SAFETY PRECAUTIONS

Be sure to read carefully the safety precautions given in data sheet and user's manual before operating the module

and follow them.

The precautions explained here only apply to the G3F-DA3V/G3F-DA3I, G4F-DA3V/G4F-DA2V, G4F-DA3I/G4F-

DA2I, G6F-DA2V/G6F-DA2I (hereafter, called D/A conversion module)

For safety precautions on the PLC system, see the GLOFA GM3, GM4, GM6 User ' s Manuals and the MASTER -

K200S/300S/1000S User's Manuals.

Design Precautions

▶ Design a safety circuit in the outside of the PLC for system safety in

case of disorder of the external power or PLC module body. Other-

wise, it can cause injury due to wrong output or malfunction.

1) The following shows analog output states according to various

settings of functions that control analog output. When setting an

output state, be cautious for safety.

Channel Setting

State

PLC CPU in RUN state.

PLC CPU in STOP state

PLC CPU in Error state

2) Sometimes, fault of output device or internal circuit can make

output abnormal. Design a supervising circuit in the outside for

output signals which can cause serious accidents.

If not provided with proper prevention, it can cause death or fatal

injury or considerable loss of property.

If not properly observed, it can cause a hazard situation to result

in severe or slight injury or a loss of property.
