Safety Instructions

Precautions regarding system design

In certain applications, malfunction may occur for the following reasons:

• The timing difference between opening and closing of the PLC power supply, the I/O modules and power equipment

• An operation time lag when a momentary power failure occurs

• Abnormality in the PLC, external power supply, or other devices

In order to prevent a malfunction resulting in system shutdown choose the adequate safety measures listed in the following:

Interlock circuits on the outside of PLC

When a motor clockwise/counter-clockwise operation is controlled, provide an interlock circuit that prevents clockwise and counter-clockwise signals from inputting into the motor at the same time.

Emergency stop circuits on the outside of PLC

Install the emergency stop circuits outside the PLC to stop the power supply of the output device.

Start PLC after other devices (Start up sequence)

The PLC should be operated after all of the I/O devices and the power equipments are energized.

• Switch to RUN mode after the start of PLC.

• Use a timer circuit to delay the start of PLC.

Watchdog timer

The watchdog timer is a program error and hardware error detection timer. It goes On when the scan time exceeds 640 ms.

When the watchdog timer is activated, at the same time the ALARM LED lights, the ALARM contacts on the power supply module turn to On, all output modules are turned Off and the module is put in halted state. (The system is in a non-processing state that includes communications with programming tools as well.)

Installation LocationBe sure to maintain a sufficient distance from wiring ducts, and other machines below and above the module for proper ventilation.

Do not install the modules stacked up or horizontally. Doing so will prevent proper cooling of the module and cause overheating inside the PLC (programmable controller).

Do not install the module above devices which generate heat such as heaters, transistors or large scale resistors.

In order to eliminate any effects from noise emission, power wires and electromagnetic devices should be kept at least 100 mm away from the surfaces of the module. When installing the module behind the doors of the operation panel, be especially careful to maintain these distances.

Space for Programming Tool Connection

Leave a space of at least 180 mm from the mounting surface for programming tool connections and wiring.

Avoid installing the module in the following conditions• Ambient temperature outside the range of 0 to 55° C • Ambient humidity outside the range of 30 to 85% RH • Sudden temperature changes causing condensation • Inflammable or corrosive gases• Excessive airborne dust, metal particles, salinity• Benzene, thinner, alcohol, other organic solvents or strong alkaline

solutions such as ammonia or caustic soda• Excessive vibration or shock• Direct sunlight • Location near high-tension wires, high-voltage devices, power cables,

power devices, or other devices with generate large power surges or electronic fields when starting and stopping (esp. if within 100 mm)

Proper compressed connection terminal• Circular type terminal (O type Lug)• Circular type terminal with insulation resistance• Open type terminal (Y type Lug)

Mounting/Dismounting Module

Mounting

1. Insert the module holding projector of the module into the module holding groove on the backplane.

2. Push the top of the module toward the backplane until it is clamped in place.

3. Ensure that the module is in place onto the backplane, and then fasten the screw using a screwdriver.

Dismounting

1. Unfasten the screw that holds the module in place using a screwdriver.

2. Hold on pressing the locking button on the edge of the top side of the module, and pull the module from the backplane.

Power Supply Module Wiring

Control power (24V)

24V can be supplied to an I/O Module.Must avoid parallel connections with other 24V power supply modules or with other power supply modules.

The power supply voltage connected to the power supply module must be within allowable limits.

Terminal for the power supply module• The terminal screw M3.5 is recommended.• The compressed connection terminal is recommended for the wiring.

Use 2mm2 twisted pair cable or larger• Use power supply wire that is thicker than 2mm2 to minimize voltage

drops.• Use twisted pair cable to minimize noise effects.

ATTENTION

Power Supply SystemUse separate wiring systems for the PLC module, I/O module, and power supply module as shown in the following diagram.

Use isolation transformer for noisy environments

• Use a low noise power supply.• Use an isolation transformer to reduce the noise as illustrated above.

GroundingGround the PLC for noisy environments • Connected to the metal part of backplane, the frame ground terminal is

connected to a solid earth ground. • Use ground wires with a minimum of 2mm2 and the triple grounding

connection which has a resistance of less than 100 Ω.• The point of grounding should be as close to the PLC as possible and the

ground wire should be as short as possible.• If two devices share a single ground point, it may produce an adverse

effect. Always use an exclusive ground for each devic

安全说明

与系统设计相关的预防措施

在某些应用场合，设备可能由于以下原因而失灵：

• 打开和关闭 PLC 电源、 I/O 模块和电源设备相互之间存在时间差异

• 由于瞬时电源故障而导致运转时间滞后

• PLC、外部电源或其它设备出现反常现象

为了防止设备失灵导致系统关闭，请采用下面列出的适当安全措施：

PLC 外面的联锁电路

如果需要控制电机顺时针 / 逆时针操作，应提供连锁电路，以防止顺时针和逆时针信号同时输入电机。

PLC 外面的紧急制动电路

在 PLC 外面安装紧急制动电路，以便切断输出设备的电源。

在其它设备后启动 PLC （启动顺序）

应该在给所有 I/O 设备和电源设备加电后再启动 PLC。

• 启动 PLC 后，切换到 RUN 模式。

• 使用定时器电路来延迟启动 PLC。

监视定时器

监视定时器是一个程序错误和硬件错误检测定时器。当扫描时间超过 640 毫秒时，该定时器打开。

在监视定时器激活的同时， ALARM LED 亮起，电源模块上的 ALARM 触点变成接通状态，所有输出模块都将关闭，模块处于暂停状态。（系统处于非处理状态，该状态还包括与编程工具进行通信。）

安装位置

请确保与接线管以及模块上下的其它机器保持足够的距离，以保证适当通风。

不要将模块层叠或水平安装。否则，会阻碍模块正常散热，而导致 PLC （可编程控制器）内部过热。

不要将模块安装在发热设备（如加热器、变压器或大电阻）的上方。

为了消除噪声辐射带来的任何影响，电源线和电磁设备应与模块表面相隔至少100 毫米。在操作面板门后安装模块时，尤其要注意保持上述距离。

编程工具连接间隙

在连接编程工具时，与安装表面之间至少要相隔 180 毫米。

电源系统

如下图所示，对 PLC 模块、 I/O 模块和电源模块分别使用单独的接线系统。

在噪声环境中使用隔离变压器

• 使用低噪声电源。

• 使用隔离变压器来降低噪声，如图所示。

接地

在噪声环境中，将 PLC 接地 • 将与底板上金属部分相连的机箱接地端连接到实心地面上。

• 请使用粗细最小为 2mm2 的接地线和电阻小于 100 Ω 的三相接地连接。

• 接地点应尽量靠近 PLC，接地线应尽可能短。

• 如果两个设备共用一个接地点，则可能会产生不利影响。始终应为每台设备单独接地。
