Chapter 11 Troubleshooting
Check the Power Supply
(Step 2)
The second troubleshooting step is to check the supply of power to your relay.
Check Voltage
If the PWR/Fault indicator is OFF, check the voltage by placing a digital
multimeter on terminals A1 and A2 as shown in
Figure 58 on page 57 .
Flashing red
5 times Output test has failed
on L11.
CI
• A short circuit has occurred, or is present,
from +24V DC (A1) or S11 to L11.
• A short circuit has occurred, or is present,
from 24V Common (A2) to L11when L11 is ON.
• Correct the fault and cycle power to the GSR safety relays.
• See additional information in
Check the Single Wire Safety
Circuit (Step 4) on page 64 .
DI and DIS
• Short circuit from L11 to L12
• Short circuit from L11 to A1 on the next
downstream relay.
• The 24V common connection to the
downstream relay has temporarily
disconnected.
• One of the downstream relays exhibited a
momentary power interruption.
• For long SWS runs, L11 can pick up noise.
Consider running the SWS signal in shielded
cable.
Flashing red
6 times
Output test has failed
on 14, 24

DIS
• External cross fault
• High capacitance load
• Check wiring.
• Remove fault or move high capacitance output connections
to 34, 44.
• Cycle power to clear the fault.
• See additional information in
OSSD Outputs on page 24 .
(1) If you do not know the correct setting, you can rotate the switch to a new setting and cycle power. If the new setting does not agree with the EEPROM, the PWR/Fault indicator continues to
flash 2X red; make a new selection and cycle power again. If the new setting agrees with the EEPROM, the PWR/Fault indicator is steady green, the GSR safety relay functions properly.
(2) DIS safety relays only.

The configuration does not agree
with the EEPROM.
All
One or more of the rotary switches have changed
during operation.
The safety relay continues to operate, and the
switches can be returned to their original
position, while powered.
EMD
On Version 200, B1 was jumpered to B2 after
configuration. In Version 203, this condition is
ignored.
Remove the jumper and the EMD safety relay
functions properly.

B1-B2 connection. All
B2 is connected to B1, after configuration. The
fault indication occurs when the EMD output is
energized. If the output is already energized, this
fault will be detected on the next energization of
the EMD.
• Remove connection and fault is cleared
automatically.
• See additional information in EMD Expansion
Safety Relay B1/B2 Inputs (Step 7) on page 74 .

Retriggerable input. EMD
Set for non-retriggerable and Logic IN input has
turned off and then back ON before the time
expired. Cycle the Logic In input signal to clear the fault
or let the timer expire and the fault clears
automatically.
A connection was made from terminals B1 to B2,
after configuration.
Repeat the configuration process; the B1-B2
connection must be made before configuration.
