Action
Fit the four attachment screws and tighten them
slightly. Make the adjustments described below
before tightening the screws properly.
In order to release the brakes, connect the 24
VDC power supply to the motor.
Fit the measuring tool to the rear of the motor.
Rotate the motor shaft several turns, using the
measuring tool.
There must always be some backlash, meaning
that the shaft should go easy to rotate!
Place the tip of a dial indicator against the
scribed mark on the measuring tool.
Set the gear play to 0.02 mm, which corresponds
to a reading on the dial indicator of 0.13 mm.
Pull gently in one direction. Note the reading.
(The gear must not turn.)
Then gently knock on the tool in the other direc-
tion and note the reading. The difference in
reading = gear play. The gear play should be
0.02 mm which corresponds to a reading on the
dial indicator of 0.13 mm.
Tighten the four attachment screws.
Perform a leak-down test.
Fill the gearbox with oil.
Refit the connection box and secure with the
three attachment screws and plain washers.
Make sure that the gasket is fitted properly!
