8.3 Function tests
Before switching from manual mode to auto mode, Maschinenfabrik Rein-
hausen recommends carrying out function tests. These function tests are de-
scribed in the following sections. Note the following points for all function
tests:
▪ You have to change the pulse type [
Page 142] to time-controlled switch-
ing pulse in order to activate the operating keys.
▪ You must ensure that LOCAL mode is activated before you can control
the on-load tap-changer manually in manual mode.
▪ You can only activate the on-load tap-changer manually in manual mode
using the
and
keys.
▪ You have to be logged in to the device as a user with a parameter config-
urator or administrator user role.
When in delivery status, you can log in as the administrator as follows:
▪ User name:
admin
▪ Password:
admin
During the function test, you must set the most important parameters. Details
on the parameters listed can be found in the Operation [
77] chapter.
8.3.1 Checking measured values and status of digital inputs and
outputs
Upon commissioning the device, check whether the measured values and
status of digital inputs and outputs are plausible. To do so, use an additional
measuring device if necessary to check the individual measured values.
1. Go to
Information > Hardware
.
2. Select the individual
assemblies
one after another and check the individ-
ual measured values or the status of digital inputs and outputs.
3. If errors arise, check the measurement path and the wiring.
8.3.2 Testing the device control function
ü
Supply voltage must be present.
ü
Switch pulse type to time-controlled pulse (default = continuous pulse).
1. Press the
AUTO/MANUAL key
to select manual mode.
2. Set the transmission ratio for the voltage transformer, current transformer
and transformer circuit.
3. Measure actual voltage and compare with the measured value displayed
on the device's main screen.
