FlexMove FC (105 mm) Conveyor System
Installation
Safeguarding can be achieved by:
• Location – locate the hazardous area out of reach of the
personnel involved.
• Guards – mechanical barriers preventing entry into the
hazardous area or protecting against falling goods.
• Control devices – machine controls preventing or inter-
rupting hazardous conditions.
• Warnings – instructions, warning labels, or sound or light
signals, alerting on hazardous conditions.
• Warnings shall be used when other means of safeguarding
will impair the function of the installation.
Torque Limiter Adjustment for Suspended
Drive Units
Introduction
The slip clutch on the drive unit is a safety device which
allows the chain to stop if the load becomes excessive. It has
two purposes:
• Prevent damage to conveyor
• Prevent damage to the products on the conveyor
(See

Torque Setting
Tighten adjusting nut hand tight (approximately ¼ turn after
first making contact). Mark nut flat closest to keyway.
Continue to tighten to specified rotation to achieve desired
torque: Note - For maximum drive torque use solid sprocket
with no overload catenary protection.
Once adjusted nut is tightened to desired rotation, bend
locking tabs down against nut flats in at least 2 locations.
Replace the Friction Facing
Change the friction facing when they reach roughly half the
thickness of 1.6 mm (0.063 in.). Before replacing the friction
facing, each part must be completely free of oil, rust and dirt.
Maintenance and Precautions after the
Replacement Procedure
Replace the friction facing and bushing if they wear.
Keep the torque limiter free from water and oil. If torque
limiter slips, re-adjust as necessary.
Safety
A
WARNING
It must be difficult to bypass or inactivate
safeguards during operation! Safety devices
should be designed to minimize discomfort
or difficulties for operators.

A
WARNING
• Before carrying out maintenance, make
sure there is no load or turning force
applied to the machine.
• Inspect operation periodically for
overloads.
A
CAUTION
• Mechanical parts may wear depending on
the rotation speed and slipping time. Check
the operation periodically.
