2 SPEED CONTROL INSTALLATION
WIRING
1. Cut a short piece of the 1/2 split wiring loom to fit the motor wires on the
jack. Install the split loom on the motor wires and apply black vinyl electri-
cal tape at teach end of the loom to retain it. See
FIG 4.
2. Uncoil the long black and red power wires. Install the remaining 1/2˝ split
wiring loom over these power wires see FIG 4.
3. Route the power wires and loom neatly along a safe path to the auxiliary
storage battery on board the trailer. Secure the loom at each end with the
rose bud loom clamps provided. Secure the loom along the mid section of
it’s path with the mounting type cable ties provided. Allow enough slack in
the wiring at the jack end to allow the control cover to be removed for
connecting the switch cable. See
FIG 1 & 2.
4. Cut the power wires and loom to a convenient length for terminating at the
battery. Strip wires back 1/2˝ and crimp on the ring terminals to each of
the red and black wires. See
FIG 4 & 5.
5. Attach the black power wire to the battery negative (-) terminal on
the battery. See FIG 5.
6. Install the manually resetable 40 AMP circuit breaker to the battery posi-
tive (+) terminal. Connect the red power wire ring terminal to the load side
terminal of the 40 AMP circuit breaker.
NOTE : The circuit breaker must be
mounted under a battery cover or inside a battery compartment out of any
wet conditions. See
FIG 5.
SWITCH INSTALLATION
1. Select a location for mounting the Jack Control Switch. The location must
be on the forward driver’s side of the trailer, within easy reach of the oper-
ator. It must also allow the operator to stand in a location where both the
entire Jack and trailer hitch can be seen. The operator must be able to
operate the switch while standing clear of the trailer NOT under the trailer.
See
FIG 1 & 2.
2. The mounting surface should be flat and relatively smooth. The gasket on
the back of the switch will allow for some small surface variations.
3. The switch cable must be routed from the mounting location over to the
Jack. The modular plug on the end of the switch cable will connect inside
the control cover on top of the Jack. Note the length of the switch cable
when choosing a mounting location. The cable must not be cut or added on
to. Excess cable can be bundled up and secured near the jack if there is
excess. If the switch is dual jack switch, it will have two cables to route.
The shorter cable will go to the jack on the driver’s side of the trailer.
4. The switch cable(s) can be either routed through a hole in the siding
behind the switch or out the bottom of the switch for surface routing of
the cable. If the cable is routed through a hole in the siding or other part of
the trailer use the bushing provided or other suitable grommet to protect
the cable from being cut at a sharp edge. See
FIG 6 & 7.
5. Install the 3/8˝ black split wire loom over the switch cable(s).
6. Mark the switch mounting hole locations using the switch box as a tem-
plate. NOTE : The switch must only be installed vertically so the door swings
up. See FIG 6 & 7.
7. Drill 2 - 3/32˝ dia. holes for the switch mounting screws.
8. Mount the switch to the trailer using the two (2) #6 x 2˝ sheet metal
screws. Do not over tighten just compress the gasket slightly about 15%.
Be careful not to crush the cable bundle.
9. Secure the split loom and switch cable within 1˝ of the switch using one of
the cable clamps provided with the #6 x 1/2˝ screws. See FIG 6 & 7.
10. Route the cable neatly about a safe path to the Jacks. Secure the cable
along its length with the mounting type cable ties provided.
11. When the switch cable is routed to within about 2 feet of the Jack
remove the cover of the control box mounted on the top of the jack by
pulling outwards on the side tabs of the box and lifting upwards.
12. Connect the modular plug of the switch cable into the mating socket
mounted on the control board. The plug will “snap” into socket and lock
in place. See
FIG 8.
13. Route the switch cable in the box as shown ( FIG 8) and secure in the
cable egress channel with the switch cable strain relief. Then secure the
cable with the special cable tie as shown. See
FIG 9.
14. Replace the cover on to the control box. It should seat all the way down
on the bottom portion of the box and “snap” in place.
15. Bundle up any excess switch cable in an out of the way location and
secure with cable ties. Secure the switch cable and loom within approxi-
mately 12˝ of the jack control box with the other 5/16 cable clamp and #6
x 1/2˝ screws. Installation is complete.
ƽ
CAUTION
PRODUCT DAMAGE
• Disconnect power to the power relay module prior to HiPot testing
of the trailer or the microprocessor will be damaged.
OPERATION
ƽ
WARNING
PERSONAL INJURY / PRODUCT DAMAGE
• Stand clear of the vehicle.
• Soft/spongy ground may cause jacks to sink.
Jack must be on firm solid ground prior to operation.
• Insure area below and around jack is clear of obstructions.
• Do not place blocks under the jack for additional ground clearance.
ƽ
CAUTION
SECURE TRAILER BEFORE TRAVELING
•
Securely latch hitch before raising landing legs.
ƽ
CAUTION
PRODUCT DAMAGE
• Do not over-extend or over-retract jacks. The electric jack has an
internal slip clutch to help prevent damage; when clicking sound is
heard, release switch. Continuing to hold the switch will wear out
the slip clutch or cause damage to the motor.
• If the motor will not extend/retract the jack and the motor is mak-
ing a ratcheting sound (clutch slipping), do not use the manual
override. Immediately contact an Atwood Service Center. Do not
use the jack until repaired or replaced.
• Do not move vehicle until Jack(s) if fully retracted.
• Damage can occur to the Jack(s), trailer and surrounding property
if the Jacks are not fully retracted prior to vehicle being move.
MANUAL CONTROL
Manual switch is always powered and will extend/retract as long as
the switch is held on for that direction.
2 SPEED CONTROL
1. Press the ON/OFF button once to activate the system. A red LED
light will come on to show the system is active. The yellow low volt-
age LED will come on momentarily during an initial diagnostic.
NOTE: This control has a time out feature that will shut the system
off approximately 5 minutes after the last button push if no other
action on the switch is made. See
FIG 10 & 11.
2. Press and release the EXTEND button(s) to auto-extend the jack(s)
to the ground. Auto-extend will only work until ground is sensed,
and should take less than a minute. Once the ground is sensed, the
EXTEND button must be held to position trailer to desired height.
The Jack operates at (2) speeds based on current draw. Under load
the Jack will optimize power by slowing it down for heavy lifting.
The Jack has 22˝ of travel; at full extension, it will make a clicking
sound. The EXTEND button should be released when this clicking
starts to prevent unnecessary wear on the clutch system.
3. Press and release the ON/OFF button when the LED is lit to deacti-
vate the system, or if no action is taken for 5 minutes the system
will deactivate on its own.
4. To retract the jack(s) the ON/OFF button may need to be pressed if
the LED is not lit. Once the system is activated, press and hold the
RETRACT button(s) to position and hitch trailer to tow vehicle. Once
the trailer is securely hitched to tow vehicle, the RETRACT button(s)
may be pressed and released to auto-retract the jack(s). Should the
auto-retract function need to be stopped for any reason simply
press any button on the keypad. Some noise is normal during the
operation of the jack, especially under elevated loads. When the
jack retracts completely it will make a momentary clicking sound
that will stop after a couple seconds.
5. Press and release the ON/OFF button when the LED is lit to deacti-
vate the system, or if no action is taken for 5 minutes the system
will deactivate on its own.
