Operating and Maintenance Manual
5. When the gap is about 0.55mm, use a feeler gauge
measuring the gap (operation gap) between the
static plate and moving plate. To con rm the four
corners of the brake have the same gap. Moreover,
to confirm the four installation screws have the
same force.
6. Screw out the adjustment sets to touch the surface
of the housing. Use torque spanner to tight the M12
screws with reserved force to make sure these
screws and the adjustment sets could lock each
other closely. Locking torque should be no less than
147Nm to avoid loosen.
7. After setting, power on the brake. The moving plate
would be pulled in. Use the feeler gauge again to
measure the gap between the brake lining and the
brake wheels to check whether the gap is 0.10mm
~ 0.20mm(contact area needs to over 75%). If not,
continue to sharp tuning the installation screws
and adjustment sets. At the same time, confirm that
during interruption of power supply, the air gap
between static plate and moving plate should be 0.5
~ 0.6mm.
Adjustment of brake monitoring
Basic requirements: No matter hot situation
or cold situation, the micro switch must
active correctly when brake works
Note
• After the installation of brake, in cold situation
with power off, use 0.2mm feeler gauge to put it
in between switch trigger and top rod (as picture
showed below). In parallel connect a multi-meter
to the terminal of brake monitoring to make sure
a close circuit.
• Take out the 0.2mm feeler but insert a 0.15mm
feeler, make sure, this time is an open circuit.
That means: the switch is action when the gap
is 0.2; while the gap is 0.15 mm, the switch is not
action.
