Target cos(phi)
In automatic mode
Prophi tries to reach
the set target power
factor by switching in
or off the capacitor
stages.
It is possible to set a target-cos(phi1) and a target-
cos(phi2). Devices without target-cos(phi) changeover
always use the target-cos(phi1). Devices with an input
for target-cos(phi) changeover switch to target-cos(phi2),
whenever the input is active.
Range 0.80cap. - 1.00 - 0.80ind.
The active target-cos(phi) is indicated in the measured
value indication for the actual-cos(phi).

Programming
Press key 1 for about
2 seconds to select au-
tomatic mode.
Press key 1 to leaf to
manual mode until in-
dication target cos
(phi).
Select the number to be
changed using key 2.
The selected number
flashes.
Change the selected
number by pressing
key 3.
Target-cos(phi1) is active.

Standard programming
In the standard programming, the settings needed fre-
quently are carried out, such as:
- target-cos(phi1),
- target-cos(phi2),
- current transformer ratio,
- learning of configuration,
- power of the first capacitive stage,
- stage ratio,
- number of stages,
- delete peak values (no indication).

Press key 1 for about 2 seconds. You return to auto-
matic mode, and the changes are saved immediately.
In delivery condition no password is programmed. The
change from automatic mode into standard program-
ming is carried out without password protection.
If a password is programmed by the user, the change
from automatic mode to standard programming is car-
ried out only after password clearance.
