System function test:
A function test should be performed after all values have been programmed step by step,
by disconnecting the controller from the power supply for a few seconds.
The controller should start automatically after it is reconnected to the power supply. If
the cosφ voltage is read in the start menu immediately after switching it on, the value
for cosφ should be low and inductive. After approx. 60 seconds, the controller starts to
switch on the individual capacitor stages.
The cos
φ
, which can be read in the start menu, should have risen in comparison to its
previous value, or it should rise when additional stages are switched on. If the compensa-
tion system is designed correctly, the controller should compensate to the set target cos
phi after a while.

This is displayed after the initialization window if the stage power has already been
programmed. The current total controller state and the currently measured CosPhi are
measured here.
Example:
Line 1: currently measured CosPhi 0.71 inductive
Line 2: the controller switches on stages; stages 1 to 4 are already switched to automatic
operation, where:
n
stages are switched on as compensation power is required.
!
stages are switched off due to overcompensation.
A
the stage has been switched to automatic mode.
a
the stage has been switched off by the automatic mode.
M
the stage has been switched on manually
m
the stage has been switched off manually.
X
the stage's measured stage power does not correspond to the configured
value (stage monitoring activated, p. the Stage monitoring submenu of the
Extras menu)
