Section 7 Service menu
The service menu is reached by the operating-mode key.
The stored maximum values of the network parameters can be displayed here as well as
the number of switching operations of the individual capacitors and their operating time.
The desired stages [in square brackets] can be selected via the arrow keys.
In addition, a fault memory is available, in which the last fault states of the system are
stored with fault code and in plain text. (This allows, for example, capturing short lived
events of overtemperature or overvoltage)

TEST-RUN
This menu point allows the user to check the settings of the PFC controller. After activation
of the test run, the controller switches each stage on and off successively and calculates
the output of the capacitors connected (this procedure is done three times to eliminate
possible errors). The values calculated are stored and can be retrieved in the following
menu item (C-POWER). At the same time, a plausibility check is conducted with the values
programmed.
Any discrepancies found are evaluated and displayed in plain text. The following errors
can be displayed:
- No measuring voltage present
- Measuring voltage too high - check programming
- Measuring voltage too low - check programming
- No measuring current? - Short circuit link in current transformer?
- Phase angle current transformer? k/l or phase transposed ?
- Current transformer ratio / 1. Step power wrong ?
- Control series? - check programming
- End stop? - check programming
- Capacitor defect or wrong power input
Note: The results displayed are messages intended to help the user trace the cause of the
error. Final evaluation remains the responsibility of the user. Under complicated (high load
fluctuations) grid conditions, 100% error recognition cannot be guaranteed.
