Important!
The pulse switch is a critical input for the OEM Controller. It signals
the system that the conveyor is moving and is the measuring device
from which the system knows when to turn equipment devices on and
off. See wash equipment vendor for location of the switch.
The OEM Controller is designed to accept all commonly used
pulse/proximity switches. There are two types that are most commonly
used, either a two wire or three wire "Sinking" (NPN) switch. The
drawing below indicates the wiring for these two types of switches.
The other type of switch is defined as a "Sourcing."(PNP) If it is
determined that this type of proximity switch is being used there are
two jumpers located just below the "CLK SINK" and "CLK SRCE"
contacts (JP1) & (JP2). These jumpers must be moved to the SOURCE
jumper position. Some pulse switches vary in the wire color. You
should check the pulse / proximity switch manual for proper color
codes.
