Leak Check Mode

Leak Check Mode

"Leak check" mode is provided to run the pump when a leak check is
needed on the system.
Basically both Vent and Purge valves are closed in order to avoid any
"artificial" leak. The power usable by the pump is limited to 20% of
the set maximum power (WIN 168).
Leak check mode can be enabled/disabled only when the pump is in
STOP, and it becomes effec-tive at the next NORMAL condition.
Leak check mode can be enabled/disabled through serial line:
When the Leak check mode is enabled, the pump will start with the
maximum power available. When it reaches full speed (normal) the
status condition (WIN 205) is identified by value 7 and the power is
limited to 20 % of the set maximum power (WIN 168). Both Vent and
Purge valves are closed.
Leak check mode must be explicitly disabled set-ting WIN 186 to
value 0.
