For the correct determination of the Motor Current Index, you must use a
signaling module for the tap position that also signals the pass-through posi-
tion as a separate tap position.
7.11.3.1 Setting MCI monitoring
The device can monitor the Motor Current Index (MCI) and trigger an event
message if the Motor Current Index is outside of the permissible range. If
you would like to monitor the Motor Current Index, you must set the following
parameters.

Determining the limit
values
Upon delivery, the limit values have not been determined. Maschinenfabrik
Reinhausen GmbH recommends the following procedure for determining the
limit values:
1. When commissioning the product, deactivate limit value monitoring.
2. After one year, display the minimum and maximum values of the Motor
Current Index (MCI extreme values [ ► Section 7.11.3.2, Page 183]).
3. Use the maximum value of the MCI + 20% for the upper limit value, and
the minimum value of the MCI - 20% for the lower limit value.
4. Repeat this procedure annually, and then reset the MCI extreme values.
Limit value monitoring
You can use this parameter to activate or deactivate Motor Current Index
monitoring.
To activate/deactivate Motor Current Index monitoring, proceed as follows:
1. Go to Settings > Parameters > Motor Current Index > Limit value
monitoring .
2. Select the desired option.
