Figure 6 Safety System Overview

Configuration of the

1732DS-IBXOBV4 Safety I/O

Note: To comply with TÜV, the 1732DS-IBXOBV4 Safety I/O module

must be configured as indicated below:

Configure the output that is connected to the I/O output cable assembly for:

• Dual (bipolar mode)

• Safety Pulse Test

Configure the input that is connected to the I/O Input cable assembly as

follows:

• Channel = Single

• Mode = Pulsed Test Input from test output X

• Source = Pulsed output from X

Safety PLC Program The program must:

• Force the output contactors to the open state when a safety-related stop

is demanded.

• Force the output contactors to remain in the open state if the SM

feedback is open after a safety-related stop is executed (see Notes).

Note: The program must inhibit the contactor closure to satisfy safety

Category 4 of 13849-1.

Note: The SM feedback logic should be implemented only after a

safety-related stop for the Bulletin 280G/281G controllers. It

should be ignored during normal operation. One of the series

contactors is used for the normal stop/start function for these

controllers. Therefore, a malfunctioning contactor circuit cannot be

distinguished from a normal running state.
