Set UP Procedure
Follow the procedure below for setting up the thyristor power controller
Checking prior to powering On
Check the following before powering on the thyristor power controller
(1) Check the wiring to the input terminals U1, V1 and W1 and output terminals U2, V2 and W2. Also check that
the grounding wires are connected to the grounding terminals (PE).
WARNING!
Be sure to connect the grounding wires of the power controller to
the ground electrodes.
Otherwise, an electric shock could occur.
(2) Check the wiring to the aux. voltage supply.
(3) Check the wiring to neutral point connection for single phase or 3ph + neutral configurations connected to
XN1 : 1
(4) Check the control circuit terminals and main circuit terminals for short circuit or ground faults.
(5) Check for loose terminals, connectors and screws.
(6) Make sure that all switches of devices connected to the power controller are turned OFF.
Power on the power controller with any of those switches being ON may cause unexpected behavior at load
side.
Power ON and check
WARNING!
Be sure to mount the front cover before turning the power ON. Do not remove the cover when the
power controller is ON.
s with wet hands.
Otherwise, an electric shock could occur.
Turn the aux. power ON and check the following points. The following is a case when no parameter data is
changed from factory defaults.
(1) Check that the assistant control panel displays no fault and set date and time
(2) Check that the used analog and digital inputs work properly
Check signals 12.11, 12.21 and 12.31 for analog inputs
Check signals 10.1 for digital inputs
Set the inputs from voltage to current if needed
Turn on the input power and check the following points.
(1) Check following parameters
a. In case of three phase system supply
Voltage between input phases
signals 1.07, 1.08, 1.09
b. In case of single phase system supply
Voltage between phase and neutral
signals 1.01, 1.02, 1.03
