Hubbell Electric Cable Reels TMR Series Installation And Maintenance Instructions

INSTALLATION and MAINTENANCE INSTRUCTIONS

DESCRIPTION

The TMR series reel is designed to automatically lift and
retrieve electric cable. The reel incorporates a rotating hollow
shaft with spool mounted outboard on one end and collector
assembly on the opposite end. The main shaft, rotating on
two flange block bearings, is driven by an electric torque motor
through a chain drive. The torque motor has an electronically
released break holding the spool stationary when the reel is
not in use.

INSTALLATION

1. Thoroughly inspect reel upon receipt for damage that may
have been caused in shipping.
2. Mount reel with the main shaft horizontal and level and
with the spool centerline in line with the cable tray. Mount
at recommended height so that proper distance from the
center of the spool to the cable tray is maintained.
Exceeding designed lift distance may lead
to poor cable spooling and
erratic operation because the electric motor
will have insufficient torque.
3. Remove collector cover. Connect conduit to line entrance
of collector housing and connect wires to brushes of
collector assembly. Brush terminals are number coded.
Be careful that incoming wires do not put strain on brush
terminals and cause brush misalignment. Replace
collector cover.
4. Connect motor to electric line of proper specification as
stamped on motor nameplate. Refer to wiring diagram
(below, in terminal box or on name plates. 3-lead
polyphase and 2-lead single phase do not require
diagram). Provide suitable overload protection based on
full load ampere rating shown on nameplate as
recommended by control manufacturer. Protect wiring circuit
with proper fuses selected according to local codes.

3 PHASE 60Hz
NOTE: Reel start/stop circuit should be wired into main machine
power master switch (not to machine travel drive motors). Frequent
starting and stopping of torque motor is not recommended.
Torque motor should be wired to wind cable only. Torque motor
compensates for direction change when cable is unwound.

OPERATION

The reel is activated when power is supplied to the torque
motor through the main starting control of the equipment.
Care should be taken to see that all electrical connections are
made before power is turned on to the collector ring and
torque motor. All nuts and bolts should be checked to see that
they are tight. Check to make sure collector ring brushes are
aligned on rings.

MAINTENANCE

GENERAL LUBRICATION: All bearings provided with grease
fittings are lubricated at the factory before shipment. They
should be regreased periodically depending on the running
time of the reel, more often if used in dusty conditions. Parts
with bearing assemblies not provided with grease fittings are
equipped with sealed bearings and do not require lubrication.
CHAIN CASE: Every three months, remove cover from chain
case, check chain tension, and lubricate chain using a lithium
based heavy duty chain lubricant.
TORQUE MOTOR GEAR REDUCER: See section 5.2.2 of
the enclosed brake motor operation instructions for grease
lubrication. This gear reducer is filled with grease when used
with 600 RPM torque motor.
TORQUE MOTOR: Reel is equipped with a Demag torque
motor. See enclosed brake motor operation instructions.
INSPECTION: Every six months inspect entire reel to see that
all nuts, bolt, screws, and set screws are in place and tight and
that no parts show undue wear. Yearly (more often depending
on duty cycle), check brushes on collector rings. Replace
brushes when worn to the shunt
