operation
Normally, if an alarm condition exists, the iF control system will shut-down the iF system. If required, you can request
'run til crash' operation. In this mode of operation, most alarm conditions will be ignored and the pump(s) will
continue to operate. Note however that for safety reasons the following alarms will shut down the iF system even if
you have selected 'run til crash':
FDP CURRENT HIGH/LOW (error numbers 310 and 312).
FDP THERMISTOR HIGH (error number 512).
EXHAUST PRESSURE (error number 3912).
On an iF1800 system, the following alarms will cause only the HMB pump to shut down, provided 'run til crash' is not
selected:
HMB POWER HIGH/LOW (error numbers 810 and 812).
HMB PHASE IMBALANCE (error number 1012).
On an iF1800 system, the following alarms will cause only the HMB pump to shut down, whether 'run til crash' is
selected or not:
HMB CURRENT HIGH/LOW * (error numbers 710 and 712).
HMB THERMISTOR HIGH (error number 912).
- (error number 701) =.

Warning/alarm messages
**
†
These display items require signals from the process tool to indicate when the process is on and off,
hence these items are only available if you have an iF Interface Module.
‡
Only available for display if the appropriate optional accessory is fitted to the iF system.
**
These messages cannot be manually selected to be displayed on the Normal display, but will be
automatically displayed on the Normal display when a warning or alarm condition exists.

The number of times the iF system has been
switched on/off.
OK indicates the cooling-water flow is acceptable;
CHECK indicates that the flow is too low, or that the
water flow-switch is faulty or disconnected: refer to
Section 6.
