Motor Thermal Overload Indicator; Manual Mode Control Feature - Rautheon UW50PV Manual De Operation

Operation

Motor Thermal Overload Indicator

A small indicator lamp on the side of the
control module will light to indicate that a
thermal overload switch in the motor has shut
off the AC power to the computer board,
thereby preventing damage to the motor
caused by overheating and/or an overload
condition. This feature protects and extends
the life of the motor.
The thermal overload switch will
automatically reset itself after the excessive
heat condition has subsided.
Before attempting to restart the washer-
extractor, determine the reason for the
overload. The following is a partial list of
possible problems:
• Washer-extractor not fully drained before
spin
• Out-of-balance condition
• Low voltage
• Loss of one phase on a three-phase motor
• Bad bearings
• Air circulation blocked to motor
Contact a service technician to correct serious
problems. Failure to take corrective action will
ultimately result in damage to the motor and/or
the inverter drive.

Manual Mode Control Feature

Manual control is available only while a
preprogrammed cycle is in progress, and if
manual mode is prompted in the WE-6
programming. With the exception of motor
speeds, the reuse tank B drain and tank A and
26
B fill valves, and the door unlock output, the
WE-6 computer outputs can be operated
manually from the keypad. (In order to ensure
proper sequencing, all motor speeds are always
controlled by the computer.)
Note: When the manual mode control feature
is activated, the operator must supply on/off
commands for the controllable outputs. If an
output is on, it will remain on until turned off
by the operator or until the assigned time for
the manual mode expires. This can be as long
as 9 minutes and 99 seconds.
In normal operation, when the program mode
switch is in the RUN position, only the
operations printed in black on the keys are
accessible to the operator.
During the manual mode, normal cycle timing
is suspended. When the manual mode is
entered, the operations printed in red on the
keys and mentioned in the following
discussion are activated.
Entering the manual mode during a fill
operation is not recommended. This bypasses
the water-level switch inputs, and the water
must be turned off manually by the operator.
The following procedure must be
accomplished within three seconds in
order to enter the manual mode:
1. Press the Manual key.
2. Then press three number keys to assign a
time in minutes and seconds to the manual
mode. For example, press key 2, key 3,
and key 0 to enter the manual mode for 2
minutes and 30 seconds.
3. Then press the Add Step key.
