ERROR MESSAGES
For certain types of failure, the controller performs an autodiagnostic test and displays one of the messages indicated in
the following table.
MESSAGE
DESCRIPTION
CORRECTIVE ACTION
HIGH VOLTAGE 1 OR 2 ERRORS
HV(X) ERROR
PANEL INTERLOCK
HV switched-off by an interlock received from the
front panel or cover. (“HV ENABLE” switch set to
OFF or unit cover removed)
1. Set the “HV ENABLE” switch to ON and
repeat the H.V. power on procedure.
2. Make sure that the cover is installed correctly.
HV(X) ERROR
REMOTE INTERLOCK
HV powered off due to an interlock received from
Remote I/O.
1. Check that the loopback plugs with the
external interlock jumpered are installed.
2. Make sure that the external interlock is
closed.
HV(X) ERROR
CABLE INTERLOCK
HV power off caused by an HV cable interlock.
1. If the pump uses an HV cable with safety
interlock, check that the connector at the
pump end is inserted correctly and that the
loopback pin at the unit end is inserted into
the related socket on the rear panel.
2. If the pump uses an single pole HV cable
without interlock, check that the jumper is
correctly inserted between the Interlock cable
HV plug and ground.
HV(X) ERROR
HV NOT FOUND
HV circuit has not been detected.
Repeat the Dual power on procedure; if the
problem persists, contact Varian for repair or
exchange.
HV(X) ERROR
HV FAULT
HV powered off caused by an HV circuit failure.
Contact Varian for repair or exchange.
HV(X) ERROR
HV OVERTEMP.
Temperature sensors inside the Dual have
detected a temperature which exceeds the safety
threshold.
1. Make sure that the environmental
temperature of E-Net Dual Controller
operation is not over 45 º.
2. Make sure that the ventilation slots on the
cover are not obstructed.
3. Make sure that the fan blades rotate freely
and that the air channeled inside the Dual
controller is not blocked by dust or foreign
matter.
Wait a few minutes for the temperature inside
the unit to cool down and then repeat the
HV power on procedure.
HV(X) ERROR
REMOTE I/O
NOT FOUND
Remote I/O card not detected.
Repeat the Dual power on procedure; if the
problem persists, contact Varian for repair or
exchange.
HV(X) ERROR
R. I/O FAULT
Remote I/O circuit failure.
1. Make sure that the Remote I/O external
connectors are connected as indicated in
this manual.
2. Repeat the Dual power on procedure; if the
problem persists, contact Varian for repair or
exchange.
HV(X) ERROR
PROTECT
The overcurrent protection was triggered with the
“PROTECT” mode of operation selected.
If necessary, select the START mode so that the
controller can work until the short circuit current is
reached.
HV(X) ERROR
SHORT CIRCUIT
A short circuit was detected on the H.V. output.
1. Check the integrity of the HV cable.
2. Remove cable from ion pump and check if
there is a short circuit in pump or cable.
