Output Time Out
This error message indicates that the relay output has been activated for an amount of time that
exceeds the user-programmed maximum allowable time. The output relay will be forced off until
the "Reset Timeout" button found in that Relay Output Page is clicked.
Possible Causes
Maximum time is set too low for
normal circumstances
.
Process value was higher/lower than
normal.
Control direction is set incorrectly.
Faulty control device attached to relay.
Relay is interlocked when it should not.
Fuse blown.
Faulty wiring of control device.
Faulty relay.
You are feeding based on flow meter volume,
and you are getting false contacts.
Faulty Sensor.
Chemical supply is empty.
Corrective Actions
Go to the Relay Output Page and increase the
programmed value for the maximum time.
Go to the Relay Output Page and increase the
programmed value for the maximum time until
the process value is brought back down to
normal levels.
Go to the Relay Output Page and check the
setting for the control direction.
Repair or replace control device.
Evaluate switch for Interlock.
Replace fuse (F2 or F3).
Correct wiring.
Replace the relay interface board.
Go to the Flow Meter Input Page and verify
that the flow total is increasing even when the
solution is not flowing.
Disconnect the flow meter cable from the
controller and verify that the flow total stops
increasing. Route the flow meter cable away
from any AC voltage and make sure that the
cable is shielded.
Clean and calibrate the electrode as described
in Section 7 above. If the calibration fails,
see troubleshooting for sensor calibration
failure.
Refill chemical supply.
