NOTE: Front and Rear Drawers are not interchangeable
“B” is used as an electrical interlock to the PLC’s 110 VAC output power
4. 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. PS3’s 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 DOWNand 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 OK
- Check switch and actuator placement and tilt actuation.
NOTE: If actuator is at a 90º or greater angle with the base, actuator will damage if machine is lowered.
