Chapter 11 Troubleshooting
Check the X32 Output
When OUT status indicator is OFF, terminal X32 does not turn ON.
Correct the fault and cycle power. The relay must be reconfigured to correct
the fault.
If the PWR/Fault status indicator is green, then measure the voltage at
terminal X32 with a digital multimeter.
shows a typical usage of X32
(point 1) as the source for the monitoring circuit. The voltage must be around
23V DC. If it is 23V, then follow the circuit and check the voltage at each of the
remaining points (2…6). If X32 measures 0V, then the relay must be replaced.
Figure 86 - Measure X32 Voltage
EMD Expansion Safety Relay
B1/B2 Inputs (Step 7)
shows the waveform from B1 to B2. This waveform is the
same as the single wire safety waveform. The waveform is present only when
the output of the EMD expansion safety relay is ON. With a digital multimeter,
the voltage measures 8…9V DC.
If the B1 status indicator is on, but no voltage is read, the expansion relay must
be replaced.
This is proper operation for the EM and EMD safety relays if they are in a
nonrecoverable faulted state. If so, then the PWR/Fault status indicator is steady
red or flashing red.
