Centra-W Cell Washer Service Manual
The Cell Washer uses AC power at 100,120, 220, 230 or 240 volts, at 50 or
60 Hz. The unit is shipped without fuses installed and must be configured for
power at your site. Do not plug in the cell washer until you have
configured it correctly. Variations in line voltage or frequency will affect the
unit's speed and other characteristics.
Caution: configuring the cell washer incorrectly will void your warranty.
Note: Refer to figure 2-2 while performing this procedure.
Locate the power entry module on the rear of the unit (Figure 2-2). On the
right side of this module is the fuse drawer. A small latch on the left holds the
drawer in place. Press the latch and slide the drawer out. When removing the
fuse drawer, be careful that the fuses do not fall out.
If the number visible in the window differs from the voltage at your site,
remove the square insert, rotate it, and reinstall it so that the correct voltage is
displayed through the window and insert appropriate fuse value (see chart
below).
Note:
Use 240V fuse drawer position for 230V service.
CAUTION:
This instrument must be configured for the correct line
voltage and must have correct fuse values. Incorrect
settings may cause fuses to blow and/or cause damage
to electrical controls.
From the following table, determine the correct fuses. Insert two fuses in the
fuse drawer and replace the fuse drawer in the power entry module. Make
sure it locks into place.
