Fuse Replacement; Mechanical Maintenance - HySecurity SwingSmart DC Series Programming And Operations Manual

Fuse Replacement

A 35A fuse is located next to the 24VDC
power supply inputs on the SDC. It requires no
maintenance, but if it were blown due to a power
surge or other unusual circumstance, it must be
swapped out with a new fuse. The symptoms of a
blown fuse appear as a control system malfunction
(i.e. all control systems may not work properly).

GENERAL MAINTENANCE

MECHANICAL MAINTENANCE

The SwingSmart DC mechanical maintenance is
not in depth or difficult, but should be performed
on a routine basis. The operator chassis is zinc
plated, but some environments may speed
corrosion of this plating.
Schedule regular maintenance and look for the
following:
z Sweep debris out and away from the chassis.
z Verify drive belt has proper tension. Check for
drive belt wear. Fraying edges or missing teeth
indicate that drive belt needs to be replaced.
Refer to "Drive Belt Tension and Alignment"
on page 105.
z Check for signs of rust. If any areas of rust are
found, reduce spread of corrosion by treating
areas with a rust inhibitor.
z Check motor. DC motors contain carbon brushes
which wear over time and must be replaced.
Failure to replace brushes will result in DC motor
damage. Brushes should be inspected every
year in high usage applications or every 100,000
cycles and replaced as needed.
z Replace worn-out batteries. Refer to "DC
Battery Replacement" on page 106 and "Clock
Battery Replacement" on page 103.
