CAUTIONS
INCORRECT
INSTALLATION
OF
THE
THYROMAT
BD
DIGITAL
CRANE
CONTROLLER CAN RESULT IN DAMAGE TO
EQUIPMENT AND / OR PROPERTY.
5.3. COMMISSIONING PROCEDURES
The following paragraphs detail the sequence that the commissioning process must follow to ensure that
the equipment is commissioned correctly:
Step 1
Ensure that all internal and external power and control connection are done according to schematic
drawings.
Step 2
Ensure that all external circuits are clear from earth faults as well as possible short circuits, which may
have occurred during installation. When testing cables and motors with an earth insulation meter ensure
that the Thyromat drive is not connected to the equipment under test. Megger high voltage testers may
cause permanent damage to the drive.
Step 3
Ensure that the rotor resistances are wired correctly, MH Automation always provides the correct values
of the resistance steps on the respective rotor schematic diagram. Follow these correctly to ensure that
motor performance is correct from the start.
NOTE
Check that the rotor feedback wiring is
wired
exactly
as
in
the
schematic
drawings.
Step 4
Verify that the Power supply and control supply are present at the panel and the Thyromat unit installed
is rated accordingly. This should be done before the Main c.b. and the control c.b.s are turned ON.
Step 5
Turn the control c.b. ON first; go through the notches one by one; verify that the correct input interposing
relays switch in the correct sequence.
Step 6
Test the end of course limit switches, ensuring that they will trip the correct input interposing relays. Test
the final limit switch and emergency stop circuit to ensure that these devices will offer the maximum
protection as far as interruption of the main supply to motors and brakes is concerned. This specific test
is extremely important and it may not be neglected.
