possible problems are as follows and can be checked
using a high powered flashlight.
•
Twisted and crossed hoisting cables
•
Power cord tangled with hoisting cables
If nothing is found or it is not easily correctable, call
Holophane at (740) 345-9631 and ask for the Field
Service Department.
3.1 Unlatching and Lowering the LD Ring
3.1.1 Rotate the drum switch to “FOR” and raise the
device until the torque limiter slips. All latch flags
should have rotated 45
°
. (See Figure 25) If any of the
flags have not rotated, lower the ring no more than 6
in., now raise the ring again to get the flags to rotate.
3.1.2 Turn the remote control switch to “REV” The
device will now be unlatched and descending the pole,
supported by the winch cable. The latch flags will align
with the ring.
3.1.3 Release the switch to “OFF” when the device
reaches the desired working height. Do not lower the
ring to less than four feet above the pole base.
3.2 Testing the Luminaires at Ground Level
WARNING
Do not break and make the circuit with the plug and
connector. Use the circuit breaker. Failure to use the
circuit breaker may result in electrical shock.
3.2.1 Turn off the circuit breaker.
3.2.2 Disconnect the circuit breaker cord from the drive
motor or transformer plug and connect it to the power
inlet on the LD ring junction box.
3.2.3 Turn on the circuit breaker, check the luminaire
performance, and then turn off the circuit breaker.
3.2.4 Connect the circuit breaker cord to the drive
motor or transformer plug and turn on the circuit
breaker.
3.3 Raising and Latching the LD Ring
3.3.1 Turn the remote control switch to “FOR”. As the
ring nears the headframe, if the ring is not equipped

Lowering Devices SECTION III
OPERATING INSTRUCTIONS
EVERY PERSON WHO INTENDS TO OPERATE THE LOWERING DEVICE SHOULD READ COMPLETELY
AND UNDERSTAND FULLY THESE INSTRUCTIONS BEFORE OPERATING THE DEVICE.
3.0 General Comments
3.0.1 The drive motor is provided with a twenty foot
long remote control cord and switch. This permits the
operator to stand a safe distance from the pole while
operating the device.
WARNING
Operate the lowering device only while standing at the
maximum distance from the pole allowed by the twenty
foot long remote control cord. Failure to follow this
procedure may result in injury or death.
3.0.2 The Holophane drive motor is supplied with two
built-in safety features which are incorporated to
prevent excessive torque from being applied to the
winch input shaft. These are:
a. a factory-set torque limiting clutch,
b. a shear pin which breaks below a predetermined
torque limit, higher than the torque limiting clutch
setting.
These two torque limiting features are for the protection
of both equipment and operating personnel.
WARNING
Do not expose the torque limiter or shear pin to damag-
ing elements or mistreatment such as sand, mud, salt
spray or other conditions which could render either
safety mechanism inoperable. Do not attempt to adjust
the torque limiting clutch or replace the shear pin. If
repairs are necessary, replace damaged equipment
with replacement components from Holophane. Failure
to follow these warnings may result in injury or death.
3.0.3 If the shear pin breaks, call Holophane at (740)
345-9631 and ask for the Field Service Department.
(See Paragraph 4.3 for the torque limiter assembly
replacement)
3.0.4 If the torque limiter releases before the LD ring
reaches the top of the pole, this is an indication that
either there is something causing the lowering device to
require an abnormally high lift force to operate or that
the clutch is releasing at an abnormally low torque
level. Carefully try to determine if there is something
wrong with the lowering device that is causing an
abnormally high input torque requirement. A couple of
