Chapter 4 – Commissioning the Supply Section with ISU
4-2 ACA 635 IBGT Supply Sections
Checks with No
Voltage Connected This table is a commissioning checklist for the supply section with no
voltage connected.
Action Information
WARNING! Ensure that the disconnector of the supply transformer is locked to open
position, i.e. no voltage is, or can be connected to the drive inadvertently. Check also by
measuring that there actually is no voltage connected.
1. Air Circuit Breaker, Relays, Switches
If the supply section is equipped with an air circuit breaker,
check the current trip levels of the air circuit breaker.
The trip levels have been preset at the
factory. In most applications there is no
need to change these settings.
Check the settings of the relays for the emergency stop
circuit. See the circuit diagrams delivered with
the device.
Check the settings of the time relays. See the circuit diagrams delivered with
the device.
Check the settings of other relays. See the circuit diagrams delivered with
the device.
Check the settings of the breakers/switches of the auxiliary
circuits. See the circuit diagrams delivered with
the device.
Check that all breakers/switches of the auxiliary circuits are
open.
2. Supply Tripping Circuit
Check the operation of the supply transformer tripping
option. This is an optional feature. See the
circuit diagrams delivered with the
device.
3. Auxiliary Control Voltage Transformer
Check the wirings to the primary and secondary side
terminals of the auxiliary control voltage transformer. See the circuit diagrams delivered with
the device for the correspondence
between the wirings and the voltage
levels.
