Commissioning window

.
In the submenus of this window, a step-by-step description of the commissioning process is given. For facilities
already in operation, the parameters set during commissioning can be read out here.
Password protection:
To protect a facility against unauthorized access of the configured parameters, a password can be entered (4-
digit number code, e.g. 4321).
In case the password gets lost somehow, the controller can be unlocked with the master password 1976.
When unlocking a password protected controller, it is possible to press a button within 300 seconds. If no button
is pressed during this period, the controller is locked again.
The password can be configured by pressing the button
U
to start entering and changing the entry position,
V
to change or set the value and
X
to save the entry.
Configuring current transformer values:
For the compensation controller to function properly, all parameters concerning the current transformer have
to be set correctly. Primary and secondary current of the transformer have to be set (submenu Iprim. / Isec.).
These parameters can be read on the nameplate of the current transformer. In addition, the phase allocation
of the transformer has to be set correctly. In the controller, the phase (L1, L2, L3) in which the current
transformer is integrated has to be set (submenu Rot.field I). If the transformer connections are mixed up (k
and l interchanged), this can be corrected with the setting -L1, -L2 and -L3.

Caution!
Subsequently changing the main transformer parameters can directly
influence the capacitor stages, for which the stage power was
determined using the learning mode. This way it is ensured that the
stage power is adequately adjusted in case of a subsequent correction
of the transformer parameters.
Manually configured stages are not taken into account here.
