Standard DC Wiring - 110/220 - VDC
Our ARC Retiring Cam is a coil operated cam,
meaning it's already a DC circuit. Please note
that the coils are dual wound, meaning that the
secondary windings are cut out as soon as the
cam reaches the energized position. This helps
keep the temperature of the unit as low as
possible.
We do not recommend that two ARC Retiring
Cams be wired in tandem, for example, front
and rear openings!
DC
Standard AC Wiring - 110/220 VAC
When replacing a 3 Phase Motorized Cam, simply connect one "HOT" phase to the AC Side on the rectifier
and the other AC to a common or neutral if you are replacing a 220volt
unit and to ensure that your retiring cam lasts as long as possible
connect as shown! If you connect two of your "HOT" wires to the cam this
will double the voltage and decrease the life of the cam.
We do not recommend that two ARC Retiring Cams be wired in tandem, for example,
front and rear openings!
Mount Cam
As Shown With Conduit Entrance At Top Of Unit, Do Not Modify Stroke of Cam. It will
cause the unit to fail prematurely.

MAINTENANCE: - As with all moving parts this operator may require maintenance. The design and construction is intended for wet and dusty locations. These
location may require that lubrication to the moving hinge, plunger and other pivot points be performed on regular basis. It is up to the elevator technician to determine
how often to lubricate the moving components based on the environmental conditions and how severe they are.

Trouble Shooting Your ARC
The ARC Retiring Cam has been an active product of C.J. Anderson &
Company since 1980. It's one of the more simpler devices that we manufacture.

- Check Incoming Voltage to Unit, 10% over or under 110 or 220 will cause
damage to the coil. - Solution: Transform Voltage To Correct Setting
- Check switch on side of unit for damage. This cuts out a portion of the coil
windings which helps minimize heat. Switch can fail in closed position and the
unit will continue to run. If it fails in the open position the cam will energize with
some manual help.
Solution: Replace Switch if this is the case.
Problem: Repeatedly Replacing Retiring Cams
If you have had to replace your retiring cam please verify the following.
- Where is the elevator when it shuts down? If it's stuck between floors the cam
will stay energized and the coil is going to get hot and fail at 105 degrees celsius.
It's designed to fail so that it doesn't start a fire. - Solution: Purchase a Cam
Protection Timer: - Part Number: 790-501-CP , New Retiring Cam or Coil
Assembly.
- Is the retiring cam located on a rear opening that's staggered? If so there's a
good chance that the cam is staying energized more than it should. Purchase a
Cam Protection Timer: - Part Number: 790-501-CP , New Retiring Cam or
Coil Assembly.
- What's the voltage of the incoming voltage to the retiring cam? If it fluctuates
or is 10% higher than what the retiring cam is rated for you're going to burn up
the coil much quicker.
- Check each door interlock contact for intermittent duty. There may be a
situation that is causing the retiring cam contact in the controller to not activate
properly and keeps the cam engergized when it shouldn't be.
- Running car on Inspection Service over long periods of time. This will
cause the cam to overheat and will fail.

Optional Accessories - Cam Timer
Our ARC is designed to fail when it reaches a
temperature of 105 degrees celsius. This is a
safety feature required by UL in order to
prevent a fire. If the elevator is stopped
between levels for long periods of time the
retiring cam will cook itself. The protection
cam timer is designed to prevent this from
happening. Simply wire it between your cam
and controller circuit and you the unit will
automatically de energize after a certain period
of time.
