Automatic shut-down

If you select 'Run 'til crash', the pump(s) can be damaged and you may invalidate any warranties on the system
equipment.
Normally, if an alarm condition exists, the control system will shut down the dry pumping system. For pumping
systems containing a dry pump and booster combination, some alarms will cause only the booster to stop, and not
the full system.
Notes: 1. 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. For safety reasons, some alarms cannot be
overridden and the system will automatically shut down even if you have selected 'Run 'til crash'.
Refer to Table
2. 'Run 'til crash' is automatically reset to 'off ' when the electrical supply is removed.
3. The Tool Interface overrides the 'Run 'til crash' state selected provided it has control of the pump.
