WIRING
1.Confirm the power is off prior to wiring. Follow all local and national electrical and building
codes.
2.The GPS-FC48-AC will self-adjust to voltages from 24VAC to 240VAC. Connect the power
wires as follows:
Black 24 - 240VAC
White Neutral or L2
Green Ground
Brown Dry Contacts/BAS terminals
3.Wire in BAS terminals (optional). The GPS-FC48-AC is equipped with dry contacts that are
normally open and close when the GPS-FC48-AC is on and has no faults. The contacts are
rated up to 250VAC and 1A.
OPERATION
CAUTION! NEVER TOUCH BRUSHES WHILE OPERATING, SHOCK MAY OCCUR
Once powered and the inline switch is in the on position, the unit initiates an internal check of
all systems. If the autocleaning wiper blade is not in the “home” position, it will move to the
home position in series with the airflow.
CLEANING CYCLE
The GPS-FC48-AC comes with a preset cleaning cycle designed to clean the brushes every three
days. The cleaning process may be activated by pushing the test button located on the top of
the unit. To change the cycle frequency, press the cleaning cycle button once. While cleaning is
in progress press and hold the cleaning cycle button for 5 seconds. The LED will start flashing.
Pressing the cleaning cycle button again will change the days between cleaning. The number
of flashes indicates the cleaning interval in days (3 flashes=3 days, 5 flashes=5 days).
TROUBLESHOOTING
1.Unit will not power up, LED not illuminated:
a.Confirm proper voltage is applied to the correct terminal(s).
a.Try an alternate power source. If using 24v try using 120v or vice versa.
2. Wiper sticks or stops on emitters:
a.Adjust height of emitters: loosen screw at base of emitter gently push or pull emitter to
a height where wiper just contacts emitter. Hold the emitter in place and tighten screw.
Verify correct height after tightening screw.
3.Wiper does not clean/ contact emitters:
a.Adjust height of emitters: loosen screw at base of emitter gently push or pull emitter to
a height where wiper just contacts emitter. Hold the emitter in place and tighten screw.
Verify correct height after tightening screw.
a.If the emitter is worn to the point where there is no adjustment, replacement emitters can
be ordered from GPS. Remove the screw and the emitter base, unplug the emitter from
the connector. Plug the new emitter in, reinstall base, adjust emitter height and tighten
screw.
4.If unit does not operate properly after verifying the above instructions please contact GPS
for additional assistance.
