The PWR/Fault status indicator has five possible states:
Status Description Action
Off No power to the relay. Apply power.
Steady green The relay is in the run state. None.
Steady red The relay is in a nonrecoverable faulted state. See Table 10 .
Flashing red A nonrecoverable faulted state See Table 11 .
Green and flashing red A recoverable faulted state. See Table 12 on page 56 .
IMPORTANT For accurate diagnostics, always start counting the flashing after the
first pause. The first cycle can be inaccurate.
Table 10 - PWR/Fault Status Indicator Is Steady Red
Indicator Description Model Possible Causes Corrective Action
Steady red
Faults that are not
described in
Table 11
and Table 12 on page 56
result in a steady red
indicator.
All
• A momentary power interruption.
• Noise on the power or signal wires.
• Cycle power to clear the fault and return the GSR safety
relay to an operational state.
• Reconfigure the safety relay (see Configuration on page 31 ).
• See additional information in Verify Grounding at the Power
Supply on page 57 .
CI, DI, DIS, and SI
Short circuit has occurred, or is present, from
+24V DC (A1) to S11 or S21 or from 24V Common
(A2) to S11 or S21.
DIS
Short circuit has occurred, or is present, from
+24V DC (A1) to 14 or 24.
SI
Excessive capacitance from input wiring to
ground, but not enough to cause flashing red four
times.
Table 11 - PWR/Fault Status Indicator Is Flashing Red
Indicator Description Model Possible Causes Corrective Action
Flashing red
1 time The GSR safety relay is
in configuration mode.
All
• The relay is shipped from the factory with no
configuration.
• The configuration process was not completed
successfully.
Continue with the configuration process. Rotate the
switches to the desired positions and cycle power.
Flashing red
2 times
Invalid configuration.
All
• Upon power-up, one or more of the rotary
switch settings do not agree with the value
that is stored in the EEPROM.
• Connections at S11 and S21 were swapped after
configuration.
• Return the switches/wiring to their proper settings/
terminals and cycle power.
(1)
• Reconfigure the safety relay.
EMD
A jumper was added from B1 to B2 after
configuration and power was later cycled.
Flashing red
3 times Invalid configuration on
DI or DIS safety relay.
DI, DIS
• During configuration, the Logic switch is set
for IN1 OR IN2 (position 1, 3, 5, or 7), but the
inputs are wired for safety mats.
• If the inputs are not closed during
configuration, the DI and DIS safety relays
show this fault on the next power cycle if the
inputs are closed.
• Reconfigure the relays for IN1 AND IN2 (position 2, 4, 6, or 8).
See Configuration on page 31
• See additional information in Safety Mats on page 22 .
Flashing red
4 times
Cross fault.
All
• You modified the wiring after configuration.
• You wired up one or more input connections as
a safety mat. When you stepped on the mat,
the GSR safety relay went to fault mode.
• Check the wiring.
• Remove the short circuit and cycle the power.
• See additional information in
Check Voltage-free Contacts
on page 58 .
CI, DI, DIS, and SI
• A short circuit occurred (and is no longer
present) or is present from S11 to S21.
• Excessive capacitance is detected on input
wiring to ground. The pulse tests waveform is
distorted.
Record the switch setting on
the front face. For example,
the logic setting is set to 3, but
it must be set to 4.
