OPTIONAL ARM ADJUSTMENT
As shipped from the factory, the front and rear arms are set to allow the axle to rest lightly on the
end caps while following the contour as it moves across the trailer.
Different types of loads and conditions may require your tarp to operate differently. For this rea-
son the system has been designed to be very versatile. Please see the steps below to adjust your
arm if need be.
To make the arms carry the axle over heaped loads: Increase the knuckle pressure on the front
and rear arms by moving the spring pin up to the middle hole. If even more lift is desired, move
the spring pin to the top hole.
To increase arm control in windy conditions:
Increase the base pivot pressure on the front and rear arms by moving the spring pin up to the
middle hole. If even more control is desired, move the spring pin to the top hole.
Recommended Maintenance:
All electrical connections should be checked regularly for corrosion. If any con¬nections are found
with corrosion, clean the connection and apply dielectric grease before reconnecting. Electrical
connections can be found at all motors, switches, contactors, limit switches, control boxes and
batteries. Motor mounting bolts should be checked periodically to ensure a minimum torque of 70
in-lbs (5.8 ft-lbs). All mounting hardware should be checked to insure all system components are
securely fastened. Visually inspect all moving parts for abnormal or excessive wear.
Field Troubleshooting Guide:
1. Check main circuit breaker at battery to make sure it is not tripped. If tripped, reset.
2. Check all connections to make sure they are properly secured both at the termi¬nal connec-
tion to the stud and where the terminal is crimped to the wire. Loca¬tions to check: battery
connection, circuit breaker near battery, male and female plugs, relay connections, motor
connection.
3. Ensure relay is powered up. If the RF module is on, the LED will be solid red. If the LED is
not on, power the module up by pushing both large buttons simultaneously for 3 – 5 seconds
until LED turns on. If RF module will not power up, remove and replace. If module will power
up but system will not function, proceed to step 2.
4. Disconnect power leads from motor. Check for motor operation in both directions. To do so,
use a set of jumper cables to go direct from battery to motor terminals (+lead to + terminal, -
lead to - terminal). To reverse direction, remove the jumper cables from terminals and swap
the leads to the opposite terminals (+lead to - terminal, - lead to + terminal). If motor does
not operate in one or both directions, replace motor. If motor operates in both directions,
proceed to step 5.
5. Reconnect input wires to motor and check for operation.
6. Using a voltmeter or test light, check for input power at relay. If using voltmeter, input voltage
should be a minimum of 12V. If voltage is good, proceed to step 6. If no or low voltage,
proceed to step 7.
7. Check voltage at relay output. To do so, connect tester leads to output terminals. Activate in
one direction, check voltage, activate in opposite direction, and confirm voltage. If no or low
voltage, relay must be replaced. If good proceed to step 8.
8. Check voltage at output circuit breaker located near battery. If no or low voltage, replace
circuit breaker.
