Figure 1-8 Series 17 & Later INPUT DEFINITIONS DOOR LOCK SWITCH INPUT When input is present, this is indication the washer door is locked. The machine controller will not command the spinner to spin faster than 50 rpm when the input is not present prior to spin. END-OF-CYCLE SIGNAL INPUT The End-of-Cycle Signal Input is energized through a user input switch on the control panel. When this is energized and the cycle has finished, the machine control will sound the End-of-Cycle signal (See End-Of-Cycle Signal Output). FABRIC SELECTION INPUTS The Fabric Selection Inputs are energized through a user input switch on the control panel. The machine control reads these inputs to determine which cycles should be run when the washer is started. MAX EXTRACT INPUT The Max Extract Input is energized through a user input switch on the control panel. When input is energized, the machine control will modify the final spin profile to the max extract profile. NOTE: If the user selects the Hand Washables fabric selection, all spins will follow the Max Extract profile regardless of whether the user selects the Max Extract option. OUT-OF-BALANCE INPUT The Out-of-Balance Input Signal is provided by three normally-closed switches wired in sequence. If any of these switches opens due to an out-of-balance condition, the signal will be momentarily lost (See Unbalance Control System). PRESSURE SWITCH INPUT The input signal from the Pressure Switch serves two purposes. It supplies power for the water valves and provides an indication to the machine control as to whether the commanded water level has been reached. When the timer advances into a cycle sequence that calls for water, power is supplied through the timer to either the wash or rinse level contacts on the pressure switch. When the water level in the tub is below the full level for that setting, the pressure switch circuit is closed, supplying power for the water valves to the machine control. When the water level switch is satisfied, the pressure switch circuit is opened and power for the water valves is no longer passed to the machine control.

GENERAL INFORMATION

INPUT DEFINITIONS
DOOR LOCK SWITCH INPUT
When input is present, this is indication the
washer door is locked.
The machine control-
ler will not command the spinner to spin faster
than 50 rpm when the input is not present
prior to spin.
END-OF-CYCLE SIGNAL
INPUT
The End-of-Cycle Signal Input is energized
through a user input switch on the control
panel.
When this is energized and the cycle
has finished, the machine control will sound
the End-of-Cycle signal
(See End-Of-Cycle Sig-
nal Output).
F
ABRIC SELECTION INPUTS
The Fabric Selection Inputs are energized
through a user input switch on the control
panel.
The machine control reads these in-
puts to determine which cycles should be run
when the washer is started.
MAX EXTRACT INPUT
The Max Extract Input is energized through a
user input switch on the control panel.
When
input is energized, the machine control will
modify the final spin profile to the max ex-
tract profile.
NOTE:
If the user selects the Hand Washables
fabric selection, all spins will follow the Max
Extract profile regardless of whether the user
selects the Max Extract option.
OUT
-OF-BALANCE INPUT
The Out-of-Balance Input Signal is provided
by three normally-closed switches wired in
sequence.
If any of these switches opens due
to an out-of-balance condition, the signal will
be momentarily lost
(See Unbalance Control
System).
PRESSURE SWITCH INPUT
The input signal from the Pressure Switch
serves two purposes.
It supplies power for
the water valves and provides an indication
to the machine control as to whether the com-
manded water level has been reached.
When the timer advances into a cycle se-
quence that calls for water, power is supplied
through the timer to either the wash or rinse
level contacts on the pressure switch.
When
the water level in the tub is below the full level
for that setting, the pressure switch circuit is
closed, supplying power for the water valves
to the machine control.
When the water level
switch is satisfied, the pressure switch circuit
is opened and power for the water valves is
no longer passed to the machine control.
