Maschinenfabrik Reinhausen 2014 56 222/08 EN TAPCON® 240
The voltage transformer's primary voltage is calculated by the device. For
correct functions, you must set the transformer data [
► 98].
To change the desired unit for the voltage display, proceed as follows:
1. Press > Configuration > General > until the desired
parameter is displayed.
ð Display kV/V.
2. Press or to select kV or V units.
3. Press .
ð The required unit is set for the voltage display.
Setting current display unit
In this display, you can set the unit for the limit values displayed for overcur-
rent and undercurrent as a percentage ("%") or absolute value ("A").
It is only possible to change from % to A if all the transformer data have pre-
viously been entered.
To set the desired unit for the current display, proceed as follows:
1. Press > Configuration > General > until the desired
parameter is displayed.
ð Display %/A
2. Press or to select % or A units.
3. Press .
ð The required unit is set for the current display.
Setting the switching pulse time
You can use this parameter to set the duration of the switching pulse for the
motor-drive unit.
If you set the switching pulse time to 0 s, the motor-drive unit is activated
with a continuous signal. The signal then remains active for as long as the
or keys are pressed.
If you set the switching pulse time to 1.5 seconds for example, after the set
delay time T1 or delay time T2 there will be a switching pulse of 1.5 sec-
onds .
