BASIC SETTING-UP PROCEDURE
Preliminary Precautions
BEFORE ATTEMPTING TO CONNECT POWER:-
CONTROLLER
Check:-
1.
The Auxiliary Supply Voltage is correctly selected on the Power Board.
2.
The Main Power Supply Voltage is within the operating range of the controller.
3.
The Armature Voltage and current ratings are compatible with controller supplied.
4.
The Field Voltage and current ratings are suitable.
5.
All external wiring circuits are correct, i.e:-
a) Auxiliary connections
b) Power connections
c) Control connections
d) Motor connections
NOTE:
Completely disconnect the controller before point to point checking with a buzzer or
when checking insulation with a megger.
6. For damage to equipment.
7.
For loose ends, clippings, drilling swarf etc., lodged in the drive or ancillary equipment.
MOTOR
1.
Inspect the motor, in particular the commutator for any extraneous matter. If an air supply is
available, it is recommended to blow over the commutator.
Check the brushes are properly seated and that the brush spring tension is adequate.
If possible check that the motor (and vent fan if fitted) can be turned freely by hand.
Preparation
MACHINE
Check:-
1.
That rotation of the motor in either direction will not cause damage.
2.
That nobody else is working on another part of the equipment that will be affected by
powering up.
3. That other equipment will not be adversely affected by powering up.
CONTROLLER
1.
Prevent application of the main power supply by removal of the supply fuses.
2.
Disconnect the load from the motor shaft if possible.
3.
If there is any doubt as to the integrity of a particular installation, insert a high wattage
resistor (i.e. fire bar elements) in series with the motor armature.
4.
If it is possible to rotate the motor, and tachogenerator feedback is in use, check that forward
rotation results in positive tacho feedback, i.e. terminal 1 is positive with respect to terminal 8
or 11.
