3) SEP – SERIES PROGRESSIVE
Series progressive Operating mode is used
for Cycle switch monitoring typically on
progressive systems.
The Pump is switched on and P1 input is
monitored and must change state twice
within the timeout period otherwise a
timeout alarm will be generated.
Once P1 changes state twice, the pump is
switched off and VIP5 Pro goes to standby
or the Lubrication Cycle is repeated for the
desired number of times.
There is no WAIT time in this mode as
progressive systems do not need venting
time.
3) PS – PRESSURE SWITCH
Pressure switch monitoring is typically used
in injector system.
The VIP5 Pro will monitor input P1 to verify
that it is an OPEN contact at the start of the
cycle.
The pump is activated and the pressure
switch must CLOSE within a timeout period
otherwise a cycle alarm is generated.
Once the P1 contact is closed, a DELAY
timer checks that the switch is not broken
for a set time before switching off the
pump. This ensures that pressure spikes at
the start of a lubrication cycles on long lines
are filtered out.
A WAIT timer can be set to allow the
injectors to reset when using multi cycle
configuration.
