Thermal Overload Indicator
To protect the AC drive from damage due to excessive
temperature, a thermal limit switch is embedded in the
drive box.
If the thermal limit switch is tripped due to damaging
conditions, the “Drive Thermal Indicator” light located
in the WE-6 control module will light and power will
be removed from the drive. The AC drive thermal limit
switch MUST be manually reset. Refer to the
following for location and instructions.
Before resetting the thermal overload switch,
determine the reason for the overload. The following is
a partial list of possible problems:
● Bad motor bearings.
● Motor cooling fan blocked or not operating.
● Excessively dirty motor (lint build-up, for
example).
● Room temperature higher than 104°F (40°C).
● Dirty fan filter.
● Fan not operating properly.
● Fan not installed properly.
