6. Depress the down arrow button one time to bring up
the base temp. screen.
See Figure 5.48.
NOTE: The screen shows the temperature of each control-
ler. If there is a temperature that is drastically dif-
ferent than the rest, refer to the control panel
trouble shooting section.
7. Depress the down arrow button one time to bring up
the motor temp. screen.
See Figure 5.49.
NOTE: If there is a motor temperature that is drastically
different than the rest, disconnect it from its con
-
troller and connect it to the opposite controller.
• If the condition follows the motor, the motor is bad.
• If the condition follows the controller, the controller
is bad.
• If the condition disappears, it was most likely a bad
connection.
8. Depress the down arrow button one time to bring up
the bus voltage screen.
See Figure 5.50.
• This screen shows the voltage at each controller.
NOTE: If one or more of the controllers show 0 volts, there
is most likely a contactor assembly issue. Refer to
the control panel troubleshooting section.
NOTE: If there is a high current draw, there should be a
matching drop in the bus voltage If the voltage
does not drop, it could indicate the current reading
is false.
