c. Lint Drawer Proximity Switches
The Lint Drawer Proximity Switches are located on the left side of the ADS-464 base, and is comprised
of six (6) parts: Junction Box, two (2) proximity switches, and three (3) cord grip switches. The switches
sense a magnet installed on the lint drawer that verify that
ALL safeties are met to the Burner Controller
and also signal the PLC that enables the ADS-464 to begin drying cycle.
NOTE: Front and Rear Drawers are not interchangeable.
B is used as an electrical interlock to the PLCs 110 VAC output power
d. Lint Chamber Pressure Switch -- PS3
The Lint Chamber Pressure Sensing Switch is located on the left rear side of the ADS-464 base. It is
an adjustable pressure switch, which incorporate a single-pole-single-throw (SPST) switch. PS3s electrical
function is to close its switch when the present pressure in the lint chamber is sufficient. This switch is
wired in series with other switches to form an interlock to the Burner Control Module.
2.0 Tumbler Tilt Problems LEVEL FAULT
A LEVEL FAULT message is generated by the incorrect state of either the FRONT or REAR sensor
switches. The following information will address the LEVEL signals, since they are associated with the
Base Electrical Junction Box.
a. PROBABLE CAUSES;
1) WIRING BACK TO THE PLC (Programmable Logic Controller)
LS1-B=FRONT DOWN SWITCH
LS2-B=REAR DOWN SWITCH
b. PROBABLE SOLUTIONS;
1) For a quick check of the FRONT DOWN and REAR DOWN signals to the PLC (Programmable
Logic Controller) perform the following:
FRONT DOWN signal test procedure 1a
REAR DOWN signal test procedure 1b
1a) Place the ADS-464 in the LOAD position; Front Up
Actuate the Front Down switch by hand
Have someone verify that PLC (Programmable Logic Controller) input #11 lights when the
switch actuator is down, and is OFF when the actuator is up.
Does L.E.D. #11 come ON when the switch is down?
If YES, wiring is okay
