Warnings -General Safety
WARNING
The safety alert symbol, black triangle with
white exclamation, is used to alert you to
potential personal injury hazards.
DANGER
SEVERE HAZARD!
KEEP OFF CONVEYORS. Climbing, sitting,
walking or riding on conveyor will cause
severe injury.
DANGER
EXPLOSION HAZARD!
• DO NOT OPERATE CONVEYORS IN AN
EXPLOSIVE ENVIRONMENT. The electric
gearmotor generates heat and could ignite
combustible vapors.
• Failure to comply will result in death or
serious injury.
WARNING
Controller must be properly grounded.
Failure to properly ground controller may
cause injury to personnel.
DANGER
SEVERE HAZARD!
Hazardous voltage will cause severe injury
or death. LOCKOUT POWER BEFORE
WIRING.
WARNING
SEVERE HAZARD!
Exposed moving parts can cause severe
injury. DO NOT ATTEMPT ADJUSTMENTS
WITH CONVEYOR RUNNING. LOCK OUT
POWER before removing guards or
performing maintenance.
WARNING
SEVERE HAZARD!
• Dorner cannot control the physical
installation and application of conveyors.
Taking protective measures is the
responsibility of the user.
• When conveyors are used in conjunction
with other equipment or as part of a
multiple conveyor system, CHECK FOR
POTENTIAL PINCH POINTS and other
mechanical hazards before system start-
up.
• Failure to comply could result in serious
injury.

Displaying the Conveyor Belt Speed
While the motor is operating, the speed of the motor output
shaft is displayed on the digital operator. To show the speed
of the conveyor belt (speed ft/minute), set the gear ratio to
the conveyor gear ratio in use.
1. Calculate the conveyor gear ratio using the formula
below:
• Conveyor gear ratio =
•where:
• Gearhead ratio = ratio of inline or 90 degree gearbox
• Pulley diameter = Diameter of Drive Pulley (Ft)
- 2200 Series = 0.104
- 3200 Series = 0.25
- 2200 Precision Move End Drive Series = 0.125
- 2200 Precision Move Mid Drive Series = 0.167
- 3200 Precision Move End Drive Series = 0.275
- 2200 Modular Belt Series = 0.125
- 5300 Modular Belt Series = 0.325
- 5200 Modular Belt Series = 0.325
• Drive Sprocket Teeth = Number of teeth on sprocket
connected to gearmotor. Note: For all side drives = 1.
• Driven Sprocket Teeth = Number of teeth on sprocket
connected to conveyor shaft. Note: For all side drives = 1.
•Example:
- 2200 Series Conveyor with a 62M015PLBDDEN Gear-
motor and a light load bottom mount with a 44 tooth
pulley on the gearmotor and a 22 tooth pulley on the
conveyor.
• Conveyor gear ratio =
