Table 1-4 System contacts

Label Name Description

TM Trip mulitply temporarily increases the alarm (Alert and Danger) setpoint values by a specific multiple (usually two or three). This function is normally applied by manual (operator) action during startup to allow a machine to pass through high vibration speed ranges without monitor alarm indications.

INHB Rack alarm inhibit Used to prevent an alarm from being declared on any monitor or relay in the 3500 rack. This is typically used when performing maintenance functions.

RST Reset Used to signal when the modules in the 3500 rack are to be reset. This contact has the same function as the Rack Reset switch on the front panel of the Rack Interface Module.

1.5 Connecting the field wiring to the I/O modules You connect transducer field wiring to a 3500 rack by using either internal or external termination. The type of termination is determined by the type of I/O modules that are installed on the rack.

13

Internal termination Connect transducer wires directly to the I/O modules

External termination Simplify wiring at the rear of the rack by using cables to connect external temination I/O modules to external termination blocks.

(1) To Transducers. (2) Internal Termination I/O Modules.

(1) To Transducers. (2) External Termination Blocks. (3) External Termination I/O Modules.

2. Operating the system This section shows how to use the various indicators and connections of a 3500 rack to control operation and collect data.

The section is divided into the following parts:

• Verifying configuration

• Operating switches

• Reading LEDs

• Collecting data from output terminals

2.1 Verifying configuration A 3500 rack can contain a variety of modules that can be set up to operate different ways. The process of setting system, module, and channel options so that all the modules in the 3500 rack work together is called configuration.

After power is applied to the rack, the configuration LED (CONFIG OK) indicates that the rack contains a complete and correct configuration.

If the configuration LED is not ON, contact your local Bently Nevada representative.

2.2 Operating switches Hardware switches let you control the operation of the rack as follows:

Reset switch clears latched alarms and resets Timed OK Channel Defeat indications. If the Configuration LED is blinking at 5 Hz, it will be stopped. This switch performs the same function as the Rack Reset contact on the Rack Interface I/O Module.

Key switch prevents unauthorized changes to the configuration settings. When the switch is in the RUN position, the 3500 rack cannot be configured. When the switch is in the PROGRAM position, the 3500 rack can be configured and the rack continues to operate normally. By removing the key, you can lock the Rack Interface Module in the RUN or PROGRAM position.

15

2.3 System contacts System contacts provide additional control by connecting external contacts to the rack.

Trip multiply ( TM ) temporarily increases the alarm (Alert and Danger) setpoint values by a specific multiple (usually two or three). This function is normally applied by manual (operator) action during startup to allow a machine to pass through high vibration speed ranges without monitor alarm indications.

Rack alarm inhibit ( INHB ) prevents an alarm from being declared on any monitor or relay in the 3500 rack. This is typically used when performing maintenance functions.

Reset ( RST ) Same function as pressing in the RESET switch on the front of the rack.

2.4 Reading the LEDs The LEDs on the front panel of 3500 modules indicate the operating status of the module.

2.4.8 Overspeed Detection System Test mode

The 3500 Overspeed Detection Module has an on board frequency generator that can generate a test signal for testing the overspeed detection function of the monitor. When the test function is enabled in the configuration software (option box is checked), you can invoke the function by closing a contact on the Overspeed Detection I/O module or via a software switch. When the test


18

is invoked, the test frequency sweeps through a start RPM and an end RPM. (The start and end RPM are set in the configuration for the module.) When the test input speed exceeds the over Alert/ /Alarm 1 and Overspeed (Danger) setpoints, the associated alarms will be driven.

TEST MODE Condition Solution

ON The overspeed module is in test mode.

No action required.

OFF The overspeed module is not in test mode.

No action required.

Alarm LED

The 3500 Overspeed Detection System (ODS) consists of mulitiple ODS modules that operate as a group. The alarms generated from this group are the result of a voting process that is set up in configuration. The alarm LEDs on the modules in overspeed detection systems indicate the result of this voting. Use the 3500 Configuration program to determine how this voting has been configured for the modules in the ODS.

ALARM Condition Solution

OFF Relay is not in alarm No action required. ON Relay is in alarm No action required.

2.5 Collecting data from output terminals Buffered Transducer Outputs provide the unfiltered output from the channels in the modules. All outputs are short circuit protected.

3. Common maintenance procedures Once a 3500 Monitoring System is operating, it continuously measures and monitors a variety of supervisory parameters. The boards and components inside of 3500 modules cannot be repaired in the field and require no calibration. This section provides information for common tasks required under normal operating condititions. For procedures that require more detailed information, refer to the reference manuals listed in 3500 Field Wiring Diagram Package (130432-01)


Lists of recommended wiring Reference manuals for 3500 modules on page iii.

This section includes the following topics:

• Changing configuration

• Replacing modules

• Verifying channels

3.1 Changing configuration The process of setting system, module, and channel options so that all the modules in the 3500 rack work together is called configuration. These settings are established and adjusted by using the 3500 Rack Configuration program.

Configuration settings are usually protected by security settings. The security setting for a typical 3500 Monitoring System that is operating normally is “Change Setpoints in Program Mode”. This section shows how to adjust setpoints. To change other configuration settings, refer to the 3500 Monitoring System Rack Configuration and Utilities Guide, part number 129777-01.

3.2 Replacing modules The boards and components inside of 3500 modules cannot be repaired in the field and require no calibration. For 3500 modules that are not operating properly, use the information in this section to replace the module with a spare and then contact your local Bently Nevada representative for information about returning the faulty module for failure analysis.

3.2.1 Replacing a main module 16. Save the configuration of the module to be replaced.

3500 modules must have valid configuration settings in order to operate properly. Replacement modules are not configured. By saving the configuration, you can download the original configuration settings to the replacement module.

The 3500 Monitoring System Configuration and Utilities Guide, part number 129777-01, shows how to save configuration files.

17. Remove the module to be replaced.

Refer to Removing and inserting a main module on page 22.

- The values of the measurement parameters of a channel are verified by using the Verification untility in the 3500 Rack Configuration program and the verification procedure in the reference manual for that module.

3.2.3 Removing and inserting a main module When performed properly, modules may be removed from or installed into the rack while power is applied to the rack.

3.2.3.1 To remove the old full-height module This procedure shows how to remove any full-height 3500 module. Refer to the reference manual for the module for details and safety considerations.

30. Loosen the screws to the main module so that they are free of the rack chassis, but still attached to the main module.

31. Use the ejectors to pry the main module loose from the backplane connectors.

32. Once freed from the backplane, the main module can be removed completely from the rack

23

3.2.3.2 To install a spare full-height module 33. Ensure that the ejectors are in their normal position, flush with the front of the

module.

34. Slide the main module into place, ensuring that they are properly in the guides provided on the floor and roof of the rack chassis.

35. Tighten the screws securely.

Application Advisory: It is important to tightly secure the thumb screws to ensure each module is Chassis grounded. Loose thumb screws may allow noise to show on the channel readings.

3.3 Verifying channels The boards and components inside of 3500 modules cannot be repaired in the field. Maintaining a 3500 rack consists of testing module channels to verify that they are operating correctly. Modules that are not operating correctly should be replaced with a spare. When performed properly, modules may be removed from or installed into the rack while power is applied to the rack.

The 3500 Monitoring System is a high precision instrument that requires no calibration. The functions of the 3500 modules, however, must be verified at regular intervals. All modules in the 3500 Monitoring System should be verified at these maintenance intervals. The procedures in the Maintenance and Troubleshooting sections of the module reference manuals describe the verification and troubleshooting process. (Refer to the reference manuals listed in 3500 Field Wiring Diagram Package (130432-01)
