DESCRIPTION
Coil OC Fail – xx:yy*
Coil yy on Slave xx has failed Open Circuit – Replace coil.
Coil CC Fail – xx.yy*
Coil yy on Slave xx has failed Closed Circuit – Replace coil.
Low Coil Voltage – xx.yy
Voltage outside the recommended voltage is being delivered to the coil yy on Slave xx or to the
baseboard – check connections.
Slave Removed – xx
Slave xx has been lost since power-up – Check connections.
Over Temperature – Slowed
Power Supply is warm. Off Time has been increased to allow the Power Supply to return to normal.
Over Temperature – Stopped
Power Supply is hot. Controller has ceased to function to allow the Power Supply to return to normal
temperature. The controller will then automatically operate.
Power Supply Low
Power Supply voltage is below the minimum voltage. Once voltage is within operating range, the
controller will automatically operate normally.
Stop (Over Temp)
Power Supply is hot. Controller has ceased to function to allow the Power Supply to return to normal
temperature. The controller will then automatically operate.
Bad MOD board xx
A faulty ‘plug-in’ board has been identified as number xx where xx is:
3. P-CTX
4. P-MOD
Contact Goyen for replacement board.
Unknown Fault xx
Firmware Error – Contact Goyen.
Exception # xx
Contact Goyen with Exception category # and Exception number xx – Contact Goyen.
1. P2 interface Board requires calibration
2. Could not communicate to baseboard slave (may indicate problem with external slave bus, but most
likely a problem with the micro or the RS485 comms on the baseboard; other options are a fault on
the micro on the P1/2 interface or possibly the 50-way cable).
3. 3.3 V rail is low (
<
3 V) – this message indicates a fault in the 3V3 supply on the baseboard.
Aux. Alarm
Auxiliary Alarm is present (P-CTX must be present).
Low Header P
Insufficient compressed-air pressure exists in header. Solenoid operation is ceased until pressure is at
acceptable levels once again (P-CTX must be fitted).
Service Alarm 100 000 cycles
100 000 complete cleaning cycles have been completed – Check control system parameters.
Service Alarm 500 000 cycles
500 000 complete cleaning cycles have been completed – Check condition of filter elements.
Service Alarm 950 000 cycles
950 000 complete cleaning cycles have been completed – Replace kits in valves.
* In the case of solenoid failure, all other solenoids will continue to operate. Alarm will be automatically cancelled on connection of a good
solenoid to the output in question.
