C. BASE SECTION ELECTRICAL MALFUNCTIONS
INTRODUCTION
There are four (4) electrical components associated with the ADS-464 base section. These components are
interfaced to a junction box, and connect to the main electrical enclosure through a disconnect cable. The “Base
Junction Box” is located on the right rear of the base section, and title of its wiring diagram is “ADS-464 Base
Electrical Junction Box Wiring Diagram.” The base section of electrical components provide:
-
Tumbler position information (Front Up - Level - Rear Up)
-
Lint chamber pressure information
-
Lint screen mechanism functioning okay information
The following information will provide a means to respond to “Base” associated Fault Messages, and to verify
ALL
the electrical signals associated with the Base Section. Refer to the ADS-464 Base Junction Box for a
detailed wiring diagram.
1.0 Base Section Electrical Components
1. Front Door Switch
The “Front Down Sensing Switch” is located on the left side of the ADS-464 base and comprises of four
parts; Head, Arm, Body, and Cord Grip device. The head is a rotating type, with a roller arm attached for
switch actuation. The body contains a double pole, double throw, normally open switch. LS has two (2)
electrical functions, A and B.
“A” provides a “rear down” signal to the PLC (Programmable Logic Controller)
“B” is used as an electrical interlock to the “rear up signal”
2. Rear Down Switch - LS2
The “Rear Down Sensing Switch” is located on the left side of the ADS-464 base, and compromises of
four (4) parts; Head, Arm, Body, and Cord Grip device. The head is a rotating type, with a roller arm
attached for switch actuation. The body contains a double-pole-double-throw (DPDT), normally open
switch.
“A” provides a “rear down” signal to the PLC (Programmable Logic Controller)
“B” is used as an electrical interlock to the “Front Up Signal”
3. 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, 2 proximity switches, and 3 cord grip switches. The switches sense a
magnet installed on the lint drawer that 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.
