8.2.3 Alarm conditions
CAUTION: LOSS OF WARRANTY
If 'Run 'til crash' is selected, the pump(s) can get damaged and all the warranties are
invalidated on the system equipment.
Normally, if an alarm condition exists, the control system will shut down the system.
For pumping systems which has a dry pump and booster combination, some alarms will
cause only the booster to stop and not the full system.
Note:
If required 'Run 'til crash' operation can be requested. In this mode of operation most
alarm conditions will be ignored and the pump(s) will continue to operate. For safety
reasons, some alarms cannot be overridden and the system will automatically shut down
even if 'Run 'til crash' has been selected. Refer to Table: Alarm actions .
'Run 'til crash' is automatically reset to 'off ' when the electrical supply is removed.
The Tool Interface overrides the 'Run 'til crash' state selected if it has control of the
pump.
