Operation of the Pressure Limits
As a safety feature of the system, it is possible to
define high pressure and low pressure limits so that
the operation will stop when the system pressure
falls outside these limits.
If the high pressure limit is exceeded, for whatever
reason (column clogged, wrong valve closed etc.),
the pump will stop and the message High pressure
limit will flash on the screen. The alarm will sound
if it is programmed to be on. The pump will start
again when the pressure drops below the limit.
This cycle will continue indefinitely.
