Check the Reset/Monitoring
Circuit (Step 5)
The OUT status indicator blinks green when the inputs to the GSR relay are
satisfied and the GSR relay is ready to turn on its outputs. The OUT status
indicator flashes green at a 1 Hz rate. The GSR relay is waiting for the
appropriate reset signal at terminal S34.
If the OUT status indicator is blinking green, but the relay does not turn on its
outputs when the reset button is pressed, measure the voltage at terminal S34
(point 1) as shown in Figure 73
. If 24V is not present when the reset button is
pushed, then check the other connections (points 2...7) in the circuit. If 24V is
present at terminal S34, then you must consider the reset configuration:
• Automatic/Manual: The GSR relay must be replaced as the output
indicator must turn solid green as soon as the voltage was present at
terminal S34.
• Monitored/Manual: If the output indicator does not turn solid green
when voltage at S34 is present between 0.25…3 seconds, then GSR relay
must be replaced.
