Error LED (333 Pump)
The ERROR light may activate (steady red) for any of the following reasons:
● A pump motor has ceased to function or has been asked to function in a way that is not
possible.
● Communication has failed with a connected pump.
● Pressure limits have been exceeded (high, File 21 and low, File 22). Any attempt to run a
file that does not exist will activate the error LED.
● Restart after a power failure has attempted to start File 23. If the file does not exist, the
software will stop the pump and activate the ERROR LED.
● Input #2 was closed, attempting to start File 23. If the file does not exist, the software will
stop the pump and activate the ERROR LED.
● A maintenance counter limit has been reached. See Resetting Maintenance Logs on page 52.
● Pump operation will cease when the maintenance counter limit is reached, even if a
method program is running.
● The audit trail is saturated.
● There is an invalid setting.
