6. Press the Enter key. The display will read
"S BAL" (short-balance-timing sequence)
or "L BAL" (long-balance-timing
sequence). This determines the load
balance timing if the machine is equipped
with either a 1305 or 1336 inverter drive
and the drive is set to control the out-of-
balance input. This prompt will have
no effect if the WE-6 senses that a
mechanical balance switch is connected
to the WE-6 balance sensing input.
If the machine has N, P or Q voltage and
50-pound capacity or less, the display
should read "S BAL" (1305 inverter
drive). Otherwise, the display should read
"L BAL" (1336 inverter drive).
The inverter drive balance-timing
sequence, if active, will occur during a
drain step. This prevents the machine from
reaching a high speed when a poorly
balanced load is sensed. The short timing
sequence ("S BAL") and the long timing
("L BAL") are as follows:
• WE-6 enters drain step (displays "D1,"
"Da" or "Db") with drain(s) initially
closed.
• Machine runs at regular wash speed
forward (not 1/2 wash speed) for a total
of 15 seconds if "S BAL" or for a total
of 20 seconds if "L BAL."
• Machine runs at distribution speed for a
total of 15 seconds if "S BAL" or for 20
seconds if "L BAL."
• Drain(s) open.
• WE-6 waits for empty condition.

(Continued)
• After empty condition appears, WE-6
waits for 10 seconds before checking
the balance signal if "S BAL" or 15
seconds if "L BAL."
• The WE-6 then monitors the balance
signal from the inverter drive for up to
5 seconds. If the balance is okay, the
computer proceeds to the next step
after the drain when the 5-second time
expires. If the balance is not okay at
any point during this 5 seconds, the
computer will return to low speed
forward (regular wash speed) for 10
seconds if "S BAL" or for 15 seconds
if "L BAL." The computer will then
repeat the timing sequence, beginning
with the third step above, in an attempt
to balance the load.
Note: Anytime the machine goes from low
speed to high speed, a drain step must be
programmed prior to the high-speed step to
allow load balancing. Otherwise, any high
speed steps for which load balancing has not
occurred will be skipped.
Note: Because of the balance procedure, the
computer will not advance through a drain
step. The computer will neither start in a spin
step nor allow any spin step(s) for which
proper balancing has not occurred. (A drain
step must precede a high-speed step or 2 or
more consecutive high-speed steps. High-
speed steps include rinse steps, medium spins,
and H1, H2, or H3 spins.)
