There are four possible Cycle Monitoring Options, explained below.

1) DUAL – DUAL LINE
Dual Line cycles generally use two pressure
switches connected to P1 and P2.
The VIP5 Pro starts the pump and must see
that P1 switch is closed within the timeout
time. After this, the Lubrication lines are
inverted by use of a directional valve.
The P2 switch must also then be made
within the timeout timer setting.
A user configurable DELAY timer can be set
to filter pressure spikes as in the PS
operating mode.
