Standard Programming; Target Cos(Phi) - janitza Prophi Operating Instructions Manual

Reactive Power Controller

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).
Standard-Programming
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.
Change from automatic mode to standard programming
and back:

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).
