Troubleshooting

Check the OSSD Connections

Confirm that voltage is present at the relay terminals and the load.

Figure 77

shows an example of the measurement points for one output channel (terminal

14). Since most safety circuits consist of two channels, repeat the checking on

the second channel (terminal 24).

Figure 77 - OSSD Output Connections

Check the PowerFlex Drive Connections

Confirm that voltage is present at the relay terminals and the safety input

terminals of the PowerFlex drive.

Figure 78

shows an example of the

measurement points for one output channel (terminal 34). Repeat the

checking on the second channel (terminal 44). The terminal connections from

34 and 44 to S1 and S2 can be reversed.

Step

Description

The voltage at 14 must be slightly less than the supply voltage. If not, then the DIS relay must be

replaced.

The voltage at A1 must be slightly less than the supply voltage and must be the same voltage as

measured at terminal 14. If not, check for an open circuit (broken wire) between terminal 14 and A1.

The voltage at A2 must be zero. If not, check for an open circuit between A1 and the voltage supply

ground connection. If A2 measures zero volts and A1 measures the supply voltage, then K1 is not

operating properly, and must be replaced.
