COATS 850 Solid State Wheel Balancer - Manual (Page 10)

Connect to Power
Your factory trained COATS ® Service Technician should do the
final check to verify the power installation before connecting the
balancer to a power supply. Failure due to improper power con-
nection will void the warranty.
Connect the balancer to an appropriate electrical receptacle.
Refer to Electrical Requirements on page 1.
Note: If pedestrian or equipment traffic might damage the
standard power cord, power outlets must be enclosed in a race-
way on the floor or in an overhead drop.
Note: Electric outlets must be solidly connected. There should
be less than 1 Ω electrical resistance between the ground pin
and earth ground. The installer or electrical inspector must ver-
ify the outlet installation before connecting the balancer. Failure
due to improper power connection will void the warranty.
Note: The green wire in the cord is the grounding wire. Never
connect the green wire to a live terminal.
Initial Testing
This should be performed by your factory trained COATS (r)
Service Technician.
1. POWER - Turn on the power to the outlet circuit breaker.
Plug the balancer into the outlet. Turn the balancer ON/OFF
switch to the on position.
An electronic BEEP will be heard when the balancer is turned
on.
Note: The balancer should be left on all day to maintain the
proper operating temperature.
2. DISPLAYS - The inner and outer weight displays will read
the current revision level for the computer software when the
balancer is first turned on.
Two LEDs will flash alternately inside the inner and outer
weight displays.
The Dynamic LED and Ounce LED will illuminate.
3. OPERATION - Mount a wheel on the shaft, lower the hood,
and push the START button. The arbor faceplate should rotate
clockwise (figure 7).
Important: If an ERROR 4 message appears, the wheel is
rotating counter-clockwise. Turn the machine off and refer to
service instructions. Disregard a short spin cycle with an inner
display reading of HUB during this initial testing.
