4 RELAY CIRCUIT BOARD SEQUENCE OF OPERATION
NOTE C
Hall Switch/Proximity Switch
This board will function with either a Hall or proxim-
ity switch. There is a sleeve jumper on the circuit board
that must be positioned for the type of switch used. The
circuit board sleeve jumper comes preset for Hall switch
operation.
To be able to determine if you have a Hall or proxim-
ity switch, look at the body of the switch. The Hall switch
has threads the entire length of the switch body while
the proximity switch has only about 1/2 the length of the
entire body. the proximity switch has an LED light in the
side of the body. The Hall switch does not have an LED
in the body, it uses the light on the 4 relay circuit board.
The Hall switch can only be used on teh 4 relay circuit
board.
