OPERATION MONITORING
During operation, the user is warned of an operating incident by:
--- One or several faults are displayed on the screen, in alternance with
monitoring parameters. When these faults are activated, the
monitoring triggers the warning phase which is followed by the hazard
phase. The period of time for these phases can be set.
--- Indicator lights on the front panel are illuminated.
--- Indicator lights on the hand held display module unit are illuminated.
--- The fault contacts on the Amat SPI connector at the rear of the pump
are open.
--- Pumping is stopped when an hazard threshold is reached.
A list of incidents is given in
chapter D
