1.0 OVERVIEW

The Nova-65 SC features unique and proprietary optics which provide a 360° beam at 5°, 10° or 20° vertical divergence. Utilizing a highly efficient compact lens, the Nova-65 SC is engineered to utilize the advanced and cost-effective technology of LEDs.

Solar modules and high-grade batteries are housed in a compact self-contained marine lantern, designed for low maintenance with a projected service life of 10 years before any significant maintenance is needed. The 10° divergence lens is ideal for fixed or floating aids to navigation while the 20° lens provides exceptional performance on buoys. The 5° lens can be used to meet specific needs that require a much longer range while still using a minimal amount of power.

The Nova-65 SC’s power efficiency provides superior performance in fixed or floating aids to navigation applications.

1.3 Technical

1.3.1 Electrical

The Nova-65 SC uses the MaxiHalo II control circuit. The control circuit assembly provides terminal connections for power source, sunswitch, fail monitor signal and synchronization signal.

Block Diagram A block diagram of the principal parts of the MaxiHalo II Control Circuit is shown in



0111258-00 Rev. B 16-Jun-16

Figure 3 Block Diagram.

Figure 3 Block Diagram Input Power Filter Battery power is supplied to the control circuit through the Input Power Filter. The Input Power Filter protects against input power transients, provides reverse polarity protection and includes circuitry to arrest induced lighting surges. Main Microcontroller The main control unit, U1, a microcontroller, controls high-level functions of the MaxiHalo II controller. It generates the flash code, requests and receives sync communications, receives inputs from the sunswitch (photocell) and configuration information from switches S1, S2, S3, S4, and S5. Sunswitch The sunswitch monitors ambient light level and produces an output signal to be measured by the MaxiHalo II controller. Day and night threshold levels can be set using SignalView. To avoid false activation, the system is designed to require the crossing of two light levels to switch to either day or night operating modes. See Figure 4 Sunswitch Diagram.



0111258-00 Rev. B 16-Jun-16

Figure 4 Sunswitch Diagram

Flash Codes 256 flash codes are pre-programmed into the MaxiHalo II controller and are user-selectable by SignalView, or by using the hexadecimal (sixteen position) switches S1 and S2. Please see Code Selection Guide (part number 011.1092-00). Adjusting Power Power to the LEDs can be set by using SignalView to adjust output as a percent of full power (0 to 100%). If using the 4-position power switch, S5, there is a choice of 16 different power levels (see Section 3.3 LED Power Configuration, below). Synchronization The ASCII Sync signal uses a proprietary Tideland protocol that employs transmitted serial data to control, monitor and synchronize multiple flash units. This system is compatible with SignalView or NavLink systems. It primarily is used to synchronize flashes of several units that use ASCII Sync and to control Main/Standby lanterns. The protocol also synchronizes on-at-night and off-at-day switch over for all connected lights.



0111258-00 Rev. B 16-Jun-16

GPS Synchronization GPS synchronization is enabled when the MaxiHalo II controller is fit with an internal GPS receiver and antenna. A GPS synchronized light flashes in synchronization with the Coordinated Universal Time (UTC) of Global Position Satellites. Thus, all GPS-equipped Tideland flashers with the same flash code flash in unison without having interconnected sync terminals or additional radio links. A GPS configured Nova-65 SC can be synchronized with other standard ASCII sync lanterns by connecting MaxiHalo II controller sync terminals. In this case, the Nova-65 SC acts as the synchronization master, producing the ASCII character to synchronize other lanterns. The light retains its remote monitoring capability. Optional Real Time Clock (RTC) The RTC is an integrated circuit interconnected to the main microcontroller. It keeps twenty-four hour time and date information. The RTC can be set and read using SignalView. When main power is removed from the light, a lithium battery maintains date and time. The primary function of the RTC is to program the light to disable during the seasonal period when there is no vessel traffic, and to re-enable during the season when vessel traffic is active. RTC Battery The RTC lithium battery is used for power when main power is disconnected from the MaxiHalo II controller. S3-2 is provided to disconnect the lithium battery from the circuit when the flasher is in storage. Before deployment when desiring to use the RTC, S3-2 must be turned on. LED Voltage Monitor The LED Voltage Monitor measures LED array voltage, which is displayed in SignalView. LED voltage varies from color to color and LED array to LED array. Fail Terminal The Fail Terminal (Figure 5 Fail Terminal Diagram), used to signal a failure to an external device, is electrically switched to ground under normal operating conditions. This is the default mode in a fail-safe system where either lack of power or a failure asserts a fail condition. In event of failure or loss of power, the terminal is open. Signal current is limited to twelve milliamperes. The default logic can be reversed (open during normal operation, switched to ground during failure) using SignalView to unselect “Invert Fail Output”.



0111258-00 Rev. B 16-Jun-16

Figure 5 Fail Terminal Diagram

LED Drive Circuit A high efficiency DC to DC converter provides virtually constant luminous output under a wide range of input power conditions. The DC to DC converter compensates for temperature changes of the LED array, conserving power at low ambient temperatures where LEDs are most efficient but batteries are least efficient. LED power is reduced below 100%, using SignalView or switch S5 (Section 3.3 LED Power Configuration, below).

1.3.2 Operation Modes

Main/Standby Installations When redundancy is required, units are paired as Main and Standby units with an external cable. The MaxiHalo II controller supports up to eight pairs (sixteen units) in this configuration. During normal operation, Main units (with odd addresses) send a signal via ASCII sync line that tells Standby units (with even addresses) that the Main units are operating normally. When a “Main Fail” signal is received, or when communication is lost, the Standby unit activates. The Standby unit remains activated until it receives a “Main OK” signal from its Main light.



0111258-00 Rev. B 16-Jun-16

When operating in the Main/Standby configuration, units must be set to operate in the Cutoff Mode (Lockout Mode disabled.) Note: Standby units respond faster to a “Main Fail” signal than to a communication failure. Standby Flash Character 58Hex The standby unit can be programmed to flash Character 58Hex [FL(6) 15S] when the Main unit fails. Seasonal Operation The MaxiHalo II controller can be programmed using SignalView to shut down on a certain date and start up on another date. The optional Real Time Clock (RTC) circuit, which maintains date and time information, is used by the main controller to determine when to shut down and when to start up. Alternate Code When the “Alternate Code During Low-Voltage” feature is enabled the MaxiHalo II controller, upon sensing a voltage below the Alternate Code Voltage threshold, initiates an alternate flash code. When the voltage drops below the Low Voltage Cutoff level, the MaxiHalo II controller disables the flasher and asserts a fail condition. When the voltage rises to the Alternate Code Voltage threshold, the MaxiHalo II controller is re-enabled and initiates with the primary flash code. Threshold levels are set using SignalView (See Figure 6 Cut Off Diagram). Note: The MaxiHalo II controller can be commanded to override the Active Code to flash the Alternate Code by selecting the “Enable Alternate Code” command in SignalView.

Figure 6 Cut Off Diagram



0111258-00 Rev. B 16-Jun-16

Standby to a Rotating Beacon The MaxiHalo II controller can be programmed as backup to a rotating beacon in a main/standby configuration. In this mode, should the rotating beacon fail, the MaxiHalo II controller assumes master status and either mimics the flash character of the rotating beacon or flashes any standard character, depending on how it is programmed. Sequenced Flash A group of Nova-65 SCs can be configured to flash in sequence similar to aircraft landing lights. Note: The GPS option must be installed in each flasher.

Monitoring With optional cable, the MaxiHalo II controller can be monitored with the following communication utilities: SignalView This software application is used for configuration changes or for simple on-site monitoring. It requires a wire connection to the monitored unit. A MS Windows based computer and SignalView kit, which includes the software, adapter, and instruction manual, are required. NavLink This system is capable of monitoring multiple Nova-65 SC units in addition to other aids to navigation. NavLink monitors by radio, satellite, telephone or internet. Operational changes such as time, date, seasonal settings, and alternate code can be made with the NavLink system. Configuration changes must be made using SignalView.

2.0 INSTALLATION

2.1 Unpacking

Unpack and inspect all hardware. In case of damage, contact your Tideland representative. Retain the original packing material in case of future return to Tideland.

WARNING! High Powered LED sources produce an extremely intense and

concentrated light source. Direct viewing of the LED should be avoided.

2.1.1 Packing List/Part Numbers

The Nova-65 SC shipping container contents include:

Nova-65 SC Light

Mounting Hardware (if purchased)

Quick Sheet Instructions 012.0062-00

Flash Character Code Booklet 011.1092-00

CD with Tideland Signal Manuals

2.1.2 Testing the Unit



Turn the On/Off Winter Charging switch to the On (Operation) position Cover the Sunswitch temporarily and verify that the Nova-65 SC flashes the correct flash code. If it does not, refer to Section 4.5 Troubleshooting.



0111258-00 Rev. B 16-Jun-16

2.2 Mounting/Physical Installation

Figure 7 Mounting Hole Dimensions

2.2.1 Mounting Hole Pattern

The Nova-65 SC unit is mounted on a 465-mm bolt circle pattern as shown in Fig. 8. Optional mounting hardware consists of 4 S/S bolts (2” x 5”), 8 flat washers and 4 self-locking hex nuts.

2.2.2 Installation

Mount the unit with bolt circle as described in the previous step. Turn the

On/Off Winter Charging switch to the On (Operation) position. Please note that this switch is a high quality, totally sealed switch with pull-to-unlock toggle level to prevent accidental toggle movement. It is placed in the Off position for shipping or storage. The Winter Charging position is for charging the battery without operating the light to help accelerate the charging of the

battery either before field installation or during long-term storage. Note: for Winter charging the lantern must be left outdoors, exposed to sunlight. The On/Off/Winter Charging Switch is located behind the cover plate as shown in Fig. 8. Once the switch is accessed, pull the switch toggle forward, releasing the locking mechanism, and move up for On/Operate position, down for Winter Charging position, or leave the switch in the middle position for shipping or storage of the lantern.



0111258-00 Rev. B 16-Jun-16

Figure 8 On/Off/Winter Charging Switch

CAUTION! Do not turn the lantern on inside a building. If the switch is left in the On/Operate position inside a building, commercial lighting can cause the solar panels to provide a high voltage, low current power to the MaxiHalo II controller control circuit which may result in a microprocessor malfunction. If the lantern does not operate, turning the switch to Off then On should reset the microprocessor

2.2.3 Changing Flash Code

The flash code is factory set to the customer’s specified code. To change the flash code, refer to the Code Selection Guide enclosed in this installation kit for switch settings. Remove the 5 screws securing the Nova-65 SC housing to access the MaxiHalo II controller control circuit. Two switches are located on the control board, Switch 1 and Switch 2. Use your thumb and index finger to rotate switches to desired locations.



0111258-00 Rev. B 16-Jun-16

Before replacing the housing, test the lantern by covering the sunswitch located on the side of the housing with a piece of black electrical tape and ensure battery is connected as described in Section 2.2.2.

2.3 Wiring

For an installation consisting of a single light, simply switching on power is sufficient to operate the light. For multiple Nova-65 SC units, SYNC and SYNC RET terminals are connected as shown in Figure 9.

Figure 9 System Wiring Diagram (Cable access is optional)

3.0 OPERATION

3.1 Safety



3.2 Configuration

The Nova-65 SC can be configured by opening the housing and using the SignalView application from Tideland. Instructions for connection and operation of the SignalView application come with the SignalView kit P/N 901.1227-00.

Refer to SignalView Manual, P. N. 011.1231-00.



0111258-00 Rev. B 16-Jun-16

Alternatively, some configuration settings can be made using the switches on the control circuit. The lantern housing must be disassembled in order to make these changes (see Section 4.3 Disassembly/Reassembly).

Figure 10 Internal Wiring Diagram



0111258-00 Rev. B 16-Jun-16

Setting Flash Code and Address Note that all flashers in a synchronized multiple-unit system must have identical flash code settings. Refer to code selection guide booklet (P.N. 011.1092-00). Use SignalView to set the desired flash code. Alternatively, locate the code selection switches, S1 and S2, on the control circuit assembly (see Figure 10 Internal Wiring Diagram). Rotate to set desired flash code. Use SignalView to set the desired lantern address. The address is a number between 0 and 62. Alternatively, locate the address switch S4 on the control circuit assembly. The address is set by S4-1 through S4-6 using binary code to represent the address. The least significant bit (LSB) is on the left (S4-1) and the most significant bit (MSB) the right (S4-6). Sixty three different addresses are available (see Figure 10 Internal Wiring Diagram for switch locations). See Table 1 S4 Address Table for switch setting for a particular address. Note: Each Nova-65 SC in a synchronized, multiple unit system must be assigned a unique address to identify the synchronization master and to signal its identity to SignalView or NavLink. The synchronization master is always the light with the lowest address. It is recommended that the lowest address always be 0 and other addresses rise in sequence without skipping any address.

For simplified operation, a stand-alone Nova-65 SC should have address 0 to communicate with SignalView.

Sequenced Flash A group of Nova-65 SC lanterns can be configured to flash in sequence similar to aircraft landing lights. This requires that each flasher have a GPS module installed. Use SignalView to enable sequenced flash and to set each light’s individual delay. Alternatively, to enable the sequenced flash feature, set switch S3-4 to “ON”. The address switch bank S4 now becomes the delay setting. Set S4 according to Table 2 S4 Sequence Delay Table. The first lantern in sequence does not need to be set for sequenced flash, but it is recommended that it be set for sequential flash with a delay of 0 seconds. Each subsequent light must be set for increasing delay depending on how far down in sequence it will flash. The sequenced flash feature applies only to solitary lanterns with GPS (as on a buoy), and must not be used in a system of interconnected lanterns.

0111258-00 Rev. B 16-Jun-16

Software Options Many software options are preset at the factory to customer requirements. These options, described in the following sections, can be changed using SignalView. Default software settings are shown in Table 3 Default Option Table.

Table 3 Default Option Table Rotating Beacon This option is enabled when the Nova-65 SC is a standby to a rotating beacon. Note that the option to use the Alternate Code During Low Voltage is not recommended when the rotating beacon option is set. Invert Fail Output This option changes the fail signal from open (high voltage) to closed (low voltage) during normal operation. Main/Standby This option is selected when two lanterns are paired as main and standby units. The MaxiHalo II controller can support up to 8 pairs (16 units). In this configuration, the standby unit remains inhibited as long as the main unit is functional. Failure of any main unit automatically enables its corresponding standby unit. Set Main/Standby configurations as follows:

Use SignalView to enable the Main/Standby feature for all units.

Set flash codes the same for all units.

Set Main units with an odd address. For example 1, 3, 5, etc.

Set Standby units with an even address number. For example 0, 2, 4, etc.

Units 0 and 1 are paired, units 2 and 3 are paired, units 4 and 5 are paired, etc.

Note that when operating in Main/Standby mode it is recommended that Low Voltage Lockout and Alternate Code During Low Voltage be disabled.

Rotating Beacon Disabled

Invert Fail Output Enabled

Main/Standby Mode Disabled

Standby Flash Code 58 Disabled

Low Voltage Cutoff Enabled

Alternate Code (Low Voltage Enable) Disabled

0111258-00 Rev. B 16-Jun-16

Standby Flash Code 58 Standby Flash Code 58 is used with the Main/Standby option to change to flash code 58 [FL(6) 15S] during a “Main failure” condition. Low Voltage Lockout The Low Voltage Lockout option prevents recovery when input voltage drops below the “Low Voltage Cutoff” level. Power to the unit must be removed in order to return to normal operation. Note that when the Low Voltage Lockout mode is enabled it is recommended that Standby Flash Code 58 and Alternate Code During Low Voltage be disabled. Alternate Code During Low Voltage When selected, this option enables an alternate flash code when battery voltage drops below a user-set level. Note that when Alternate Code During Low Voltage is enabled it is recommended that Standby Flash Code 58 be disabled. Communication Filter When enabled, this option, which is normally not enabled, inhibits the lantern from listening to the sync signal during LED ‘on’ periods. The light needs to be able to “see” other lights on the sync line in order to establish synchronization. Under conditions of extreme noise, this option can be selected to minimize false signals. Before selecting this option, be sure to eliminate other potential noise sources, such as poor connections. When enabled unnecessarily, the communication filter may reduce the ability of lights to synchronize. Low Voltage Cutoff Configuration of Low-Voltage Cutoff and Alternate Code By enabling Low-Voltage Cutoff only, the light ceases flashing at a selectable low voltage and returns to normal operation when the voltage rises above a selectable, slightly higher voltage. By enabling both Low-Voltage Cutoff and Alternate Code During Low Voltage, the light begins flashing the alternate code when voltage is below a selectable low voltage and ceases flashing at a lower selectable voltage. The light resumes normal operation when the voltage rises above the Alternate Code during Low Voltage Threshold. For Low Voltage Cutoff Only:

Using SignalView, set the low-voltage cutoff level to the lowest voltage at which the lantern is to flash. Using SignalView (under Secondary Data,) set the Alternate Code during Low Battery Threshold to the voltage level for which the system is to return to normal operation. MaxiHalo II controller adds 0.2 volts for hysteresis. The Alternate Code during Low Voltage option (under Options) must not be

enabled, but its voltage level is used as a “Return to Normal” voltage. Factory default is 11 VDC.

Low Voltage Cutoff and Alternate Code During Low Voltage:

Using SignalView (under Options), enable Alternate Code during Low Voltage option. Using SignalView (under Secondary Data), set Alt. Code Low Battery Threshold to the minimum voltage required for the primary flash code (Factory default is 11 VDC) and Low Battery Cutoff Threshold to the minimum voltage required for system operation (factory default is 8.8 VDC.)

Sunswitch Level Configuration Sunswitch day level and sunswitch night level can be set using SignalView. (See Section 1.3 and the SignalView manual for more information on sunswitch operation.) Seasonal Shutdown Configuration Seasonal ON and OFF dates can be set using SignalView. When the optional Real Time Clock circuit is installed, and seasonal shutdown is enabled, the internal clock must be set to the current time. (See Section 1.3.2 Operation Modes and the SignalView manual for information on Seasonal Shutdown operation.)

Configuration Switch Settings These settings can only be made using the controller switches. The lantern housing must be disassembled in order to make these changes (see Section 4.3 Disassembly/Reassembly). S3-1 selects Sunswitch Type. Off or away from the center of the PCB is selected for a 24K sunswitch; on or toward the PCB center for an 8K sunswitch. S3-2 connects the RTC Battery to the clock circuit. The RTC lithium battery is used for power when main power is disconnected from the MaxiHalo II controller. Setting S3-3 on or toward the center of the PCB in conjunction with S4-8 on or toward the center of the PCB configures the flasher for Pulse-SYNC Operation, compatible with API Flashers.

3.3 LED Power Configuration

The Nova-65 SC is factory set for power at 5 watts to the LED array. Power to the LEDs can be adjusted from 0 to 100% of full power, as needed for the installation. Power adjustment trades off between effective intensity and power consumption.

Effective Intensity Tables can be found on our website at www.tidelandsignal.com. The tables can be used to calculate effective intensity at any power setting (or power setting for any effective intensity).

http://www.tidelandsignal.com/



0111258-00 Rev. B 16-Jun-16

LED array power can be configured using SignalView™ to adjust output as a percent of full power (0 to 100%, in steps of 1%). If using the 4-position power switch, S5, instead of SignalView, there is a choice of 16 different power levels (see Table 4 Power Selection Table, below).

Table 4 Power Selection Table

CAUTION! An incorrect power setting can ruin the LED array.

3.4 Configuring as Backup to a Rotating Beacon

The Nova-65 SC can be configured to act as a backup to a rotating beacon using SignalView™ to select the Main/Standby option and setting the address and flash codes as described below.

Setting Rotation Period For rotating beacons, the lens rotation period is controlled by the beacon’s motor control circuit. The period is also configured into the Nova-65 SC for faster coordination of the two flashes upon failure of the rotating beacon. Use SignalView™ to set the rotation period. Alternatively, use S4-2 through S4-5 according to the table below. (See Figure 10 Internal Wiring Diagram for the location of S4 switch on the MaxiHalo II controller control circuit.)

Setup for Main/Standby Operation Main/Standby systems configured using rotators are limited to one Main and one Standby. There are two types of Main/Standby configurations for rotating beacons, based upon the Main/Standby configuration described below. In either case, Main and Standby units must have the same flash code setting, which are the Standby’s flash code and not the Main’s fixed flash code.

Note: When making settings using S4, the functions of the S4 switches change when Rotator Function is enabled. See Table 5 S4 Function Table.

Case 1 – Main rotating beacon and Nova-65 SC standby flashing a selectable flash code:

Use SignalView to set both lights to Rotating Beacon

Use SignalView to set both lights to Main and Standby feature

Use SignalView or switches to:

Set Standby address to 0

Set Main address to 1

Set both units Rotation Period

Set both units to inhibit Mimic mode

Set both units to the Standby flash code

Set both units that Standby is not a rotator

Case 2 – Main rotating beacon and Nova-65 SC standby to mimic a main rotating beacon

Use SignalView to set both lights to Rotating Beacon

Use SignalView to set both lights to Main and Standby features

Use SignalView or switches to:

Set Standby address to 0

Set Main address to 1

Set both units to enable Mimic mode

Set both units to match the Main unit flash character

Set both units that Standby is not a rotator

4.0 MAINTENANCE

4.1 Safety



4.2 Service

Tideland recommends that maintenance be conducted at a repair depot where material handling equipment and a clean work environment are available. Inspect the lantern annually for damage. Any housing damage must be promptly repaired or the light replaced to minimize internal corrosion. The routine maintenance interval for the lantern is once per year.

CAUTION! Do not use the following substances on the lens: acetone, alcohol, benzene, carbon tetrachloride, fire extinguisher fluid, dry cleaning fluid, lacquer thinner, pumice soaps, or kitchen scouring compounds.

Cleaning Procedure The lens, lantern housing and sunswitch lens should be cleaned as required by local conditions (once a year minimum.) To clean the lantern and/or lens: 1. Using a soft cloth or soft bristle brush, wash the lantern with water and a mild nonabrasive soap or detergent. 2. After wetting, remove any caked dirt or mud with the hand, not with any instrument or scraper. 3. Rinse with clear water. 4. Remove grease or oil using hexane or kerosene. Wash with a mild non-abrasive soap or detergent and dry. 5. Minor foreign matter on the lens can be removed using the Tideland lens cleaning cloth (P.N. 901.1159-00) by gentle rubbing.

There are no wear out parts

4.3 Disassembly/Reassembly

Note: Exercise care when disassembling or reassembling the Nova-65 SC in order to keep from pinching the o-rings. If new o-rings are used, please use o-ring lubricant. To remove the battery hosing remove the 8 screws that are holding the battery housing to the base. See Figure 13 for an exploded diagram of the Nova-65 SC.

4.4 Moisture Protection

The lantern is equipped with a soft EPDM gasket at the base, as shown in Figure 15, to provide sealing against water ingress.

CAUTION! When installing the unit, make sure that proper flat washers are used. After replacing batteries or servicing the inside of the unit, tighten the M6 hardware (8) that secures the battery housing to the base. Tighten the customer supplied M12 mounting hardware (4) when mounting the self-contained assembly to the structure. Check all hardware after installation is complete

4.5 Troubleshooting

Following is a guide for field troubleshooting the MaxiHalo II controller.

4.5.1 Mechanical Verification

Verify that all cables are intact and connections firmly seated. Verify that all wiring is correct (see Figure 10 Internal Wiring Diagram).

4.5.2 Configuration Verification

Refer to Section 3.2 Configuration to verify flash code and address settings.

4.5.3 Testing the Nova-65 SC

Assuming the Nova-65 SC has been turned on, cover the sunswitch with black electrical tape and observe the Flasher operating. Confirm flashing of the unit consistent with the preset timing code (see Section 3.2 Configuration). When the flash code is set to 00 Hex the light should illuminate continuously. When LEDs do not flash, use SignalView™ to assure the flasher is not in low-voltage cutoff or other failure mode (see Section 4.5.4 Troubleshooting with SignalView™ ). When not in any fail mode, then the problem is in either the control circuit or the LED array.



0111258-00 Rev. B 16-Jun-16

Testing LED Array



Testing of the LED array will require opening the lantern housing (see Section 4.3 Disassembly/Reassembly). Measure the voltage between LED+ and LED- when the array is under power (see Figure 10 Internal Wiring Diagram). A properly functioning LED string will measure 25 to 35 VDC, depending on LED color. When no or very little voltage is measured, the power supply is malfunctioning and it should be replaced. When 45 to 60 VDC is measured, depending upon input voltage, then the LED string is open and the light should be returned to the repair depot.

4.5.4 Troubleshooting with SignalView™

SignalView™ monitors the Nova-65 SC and provides information that is helpful in troubleshooting. The following sections describe check points that are read and displayed by SignalView. LEDs Enabled: The control circuit checks conditions listed below to determine when the LED array should flash. When any one of these items is true SignalView will indicate that the LEDs are not enabled:

Unit is set for low voltage cutoff and input voltage is too low

Sunswitch is in bright light or is defective (shorted)

Unit is set in software for main/standby and has an even address (is in standby mode)

The real time clock is enabled and is currently signaling seasonal shutdown mode.

Error Status Messages SignalView monitors the Nova-65 SC and reports the following: Low Voltage Cutoff Indicates the battery voltage has dropped below the operator-set voltage level. This condition asserts the “Fail” terminal. Main Fail Main/Standby option is selected, the Nova-65 SC has determined that the main lantern has failed and the standby lantern is operating.



0111258-00 Rev. B 16-Jun-16

Lantern Failure The fail terminal is asserted. Nova-65 SC has experienced a general failure. When no other failure is indicated by SignalView, a failure other than those specifically detected by SignalView has occurred. Low Voltage Lockout Low Voltage Lockout has been activated by a low voltage condition. The lockout is reset by cycling input power. Standby Fail The Standby unit in the Main /Standby system has failed. Flash Inhibited This indicates that the flash has been suspended. This message is generated either when the lantern is in RTC winter mode or the flash has been inhibited by overriding sunswitch control. Alternate Flash due to Low Voltage The alternate code is activated because of a low voltage condition. Remove the black tape from the sunswitch and observe that the light extinguishes.
