10. COMMISSIONING AND OPERATION MANUAL
WARNING!
The information in this manual does not purport to cover all details or variations in
equipment, nor to provide for every possible contingency to be met in connection
with installation, operation or maintenance.
Should further information be desired or should particular problems arise which
are not covered sufficiently for the purchaser's purposes, please contact your local
Solcon office.
Further, the contents of this Manual shall neither become a part of nor modify any
prior or existing agreement, commitment or relationship. The sales contract
contains the entire obligation of Solcon. The warranty contained in the contract
between the parties is the sole warranty of Solcon. Any statements contained
herein do not create new warranties nor modify the existing warranty.
Safety
Precautions!
Read this manual carefully before operating the equipment and follow its
instructions.
Installation, operation and maintenance should be in strict accordance with
this manual, national codes and good practice. Installation or operation not
performed in strict accordance with these instructions will avoid
manufacturer’s warranty.
Never open the medium voltage doors of the cabinet while medium
voltage is connected to the cabinet.
Do not open the medium voltage doors, even if the motor is not running
and the Line Contactor is open. Medium voltage may still be connected to
the cabinet (upstream the contactor)!
Ensure, before opening the medium voltage doors, that the input medium
voltage lines are disconnected from mains and grounded.
It is absolutely forbidden to change the position of the internal selector
switches while Line Contactor is closed.
Before closing the doors for medium voltage operation, ensure that the low
voltage Test Harness is not connected. The Test Harness is only used for
the low voltage test. As a rule, always disconnect the harness immediately
after ending the low voltage test. It should be mounted inside small plastic
bag in the drawing pocket. This Test Harness is equipped with long tape,
intended to prevent forgetting it connected. Never cut this warning tape.
Leave open for its full length and laid in such a way that the harness will
not be forgotten connected after the low voltage test.
The Line Contactor is not designed for disconnecting high short circuit
currents. Therefore the trip relay terminals 39-40-41 must be used to open
the upstream breaker. Alternatively, upstream fuses can be used.
The software of the external PLC (if used) controlling the starter must
check the status of the trip relay in customer terminals 39-40-41. Upon
detecting a trip signal, the PLC should open the Remote Start / Stop
contact (connected to customer terminals 15-16) immediately.
10.1 Operational notes
The seven Logic Inputs of the Control Module (terminals 4-5-6-7-8-9 & 19-20-21) are high impedance
inputs. Add an auxiliary relay for each Logic Input connected through long wire to a remote location
outside the HRVS-DN cabinet.
Do not connect power factor correction capacitors in parallel with the motor at the output side of the soft
starter. It may cause an immediate damage to the starter and/or capacitors and can be dangerous.
Do not use power factor capacitors at all if the starter is powered from a generator. The capacitors may
interfere with the voltage regulator of the generator. They may cause significant dangerous over voltages.
If there are power factor capacitors connected upstream of the starter, and they are mounted close to the
starter, it is recommended to disconnect the capacitors until the end of commissioning.
Perform a Megger test to the motor and its cables while disconnected from the cabinet. After the end of
test, leave the cable unconnected to enable the low voltage test.
