Operation
Stop Routine
(Continued)
Note: If the desired action is not programmed
in the final cycle step, the computer will
default to the most recent action in the cycle. If
the cycle stops prematurely, the most recent
action at the time the cycle is interrupted will
be in effect during the stop routine.
The display will read "W1-cc," "W2-cc," or
"W3-cc" for Wash 1, Wash 2, or Wash 3 action
during the entire STOP routine until the final
10 seconds. (The "cc" here stands for the
current cycle number and will be represented
by numbers in the actual display.) During the
final 10 seconds, the display reads "STOPcc."
The display will then read "DONEcc." At that
point, the door can be opened.

Balance Detection

The washer-extractor may be equipped with
either a Vibration Safety Switch Detection
System or a Vibration Safety Switch Detection
System with an Inverter Drive Balance
Detection System. All machines of the Design
5 series or lower will have only the vibration
safety switch detection system. All machines
of the Design 6 series or greater will have both
the vibration safety switch and inverter drive
balance detection systems.

Balance Switch Detection

The vibration safety switch detection system
utilizes a micro-switch mounted between the
faces of the A-frame to signal the WE-6
computer when the load imbalance is too great
for high extract speeds. If the washer-extractor
is equipped with ONLY the vibration safety
switch detection system, the switch will signal

the computer that an unacceptable load
imbalance has been detected during the extract
speed. At this point, the computer display will
illuminate the out-of-balance LED indicator
(this indicator is located in the upper left
corner of the first digit on the display). The
computer will then command the motor to
slow down, re-distribute the load, and try again
to achieve the programmed spin speed again.
The computer will attempt to redistribute the
load in this manner up to three times. On the
third attempt, if an imbalance condition is still
detected, the computer will abort the spin
speed step(s) and advance to the next non-spin
speed step.
However, if the washer-extractor is equipped
with BOTH the vibration safety switch and the
inverter drive balance detection systems, the
function of the switch is slightly different. The
inverter drive will monitor load imbalance
conditions during the distribution speed step,
and if the load is sufficiently out-of-balance,
the computer will attempt to re-distribute the
load again. The computer will attempt to
balance the load in this manner up to two more
times for a total of three attempts. If the
inverter drive continues to detect an out-of-
balance load on the third attempt, the computer
display will illuminate the out-of-balance LED
indicator, and the computer will determine the
maximum safe spin speed up to a maximum
speed of 235g. In addition, during any spin
speed step, if the vibration safety switch
detects a severe imbalance condition, due to
improper installation or improper loading of
the washer, the computer will abort the
remaining portion of the cycle and stop the
machine. The display will flash "BAL DR"
while aborting the cycle until the door has
been opened.
