P4-01
(0CFA)
Pre-Charge Level Pre-Charge Level
Runs the drive at the frequency set in P4-02.
The drive will stop when one of the following conditions occurs:
• The feedback level rises above the level set in P4-01
• The pre-charge time set in P4-03 expires
• The low water digital input is deactivated (#8F)
Default: 0.0 PSI

P4-03
(0CFC)
Pre-Charge Time Pre-Charge Time
Sets the maximum allowed Pre-Charge time.
When P1-01 is set to 3 (MEMOBUS network), the function is
active only on the first drive to run in the network.
Setting this parameter to 0.0 disables the function.

Pre-Charge Loss of
Prime Level
Pre-Charge LOP
Detects loss of prime in the pump.
When the measured quantity determined by P1-18 drops below
this level for the time set in P1-20 and the output frequency is
at the level set in P4-02, a “Loss of Prime” condition occurs.
The drive responds to the “Loss of Prime” condition depending
on the setting of P1-22, Loss of Prime Selection.
Default: 0.0 A

Detects loss of prime in the pump.
When the measured quantity determined by P1-18 drops below
this level for the time set in P1-20 and the output frequency is
at the level set in P4-06, a “Loss of Prime” condition occurs.
The drive responds to the “Loss of Prime” condition depending
on the setting of P1-22, Loss of Prime Selection.
