3. Accumulating error is almost always the result of the wheel not traveling in a path
parallel to the motion of the axis. This causes the wheel to skip at certain regular points
in its travel.
• Inspect the base to determine if it has been damaged. A damaged base will usually
have crinkles in the small, triangle-shaped plates on the front and back.
• Use a bubble level or an indicator to adjust the puller screws so that the base is
parallel to the running surface.
• Inspect that the sensor is not cocked so that the case contacts the running surface.
• Inspect the wheel for chips that are adhered or for gouges.
4.8 Electrical
4.8.1 Checking A/C Voltage
This procedure tests for the 115V power for the control.
• Use a Voltmeter, reading A/C volts.
• Acceptable range is 100V to 130V.
Note: systems running consistently close to the low values may have problems when normal voltage
fluctuations push the voltage out of the acceptable range.
Test the following in the order presented:
Problems Here: May Indicate:
1.
The wall outlet.
•
Fuse blown in the shop electrical panel.
• Incoming service from local utility is bad.
Call the electric company.
2. The control power cord from the wall.
Check the end that goes to the electrics
box.
• Power cord defective.
3. Check the top fuse on the electrical cabinet.
It should be an 8-amp fuse.
• If this is blown then power will not reach
the 4 outlets on the electrical box.
3. Check the 110-power cord to the pendant. • Power cord defective
4.8.2 Checking Fuses
CAUTION!
Turn off power before removing and replacing
There are 4 fuses to check in the system. There are 2 in the pendant and 2 in the electrical
cabinet, and one on the breakout box. The top fuse in the electrical cabinet is 8 amps and
fuses power to the pendant. The bottom fuse is 5 amps and fuses power to the auxiliary 1,
auxiliary 2 and lube pump outlets. The 2 fuses in the pendant are 1 amp and 12 amps. The
12-amp fuses the cable breakout box, and the 1 amp the pendant.
If you have the auxiliary function option then there is 1 more fuse to check on the cable
breakout box for the coolant or mister option.
To check fuses:
1. Use a Volt/Ohmmeter; select “OHM”.
2. Remove the fuse completely from the pendant, electrics box or cable breakout box.
3. Place a lead of the meter on each end of the fuse.
