3.1   HANDLE SWITCH COUPLING

1.  The handle switch coupling on the side of the MICON 500C must be connected to the

dispenser handle.  In most installations, the dispenser handle can be coupled directly to the
MICON 500C.  The MICON 500C handle switch can be turned to the 

ON

 position by rotating

the actuator shaft 90 degrees in either a clockwise or counterclockwise direction.  The
direction of rotation is dependent upon the position of the dispenser handle in relation to the
coupler.

To verify correct placement of the actuator, the flat (beveled) side of the shaft should
be in the battery ON position when the dispenser handle is OFF.  This will be flat side
UP (battery actually is ON in any position except flat side DOWN).

POSITION

THE COUPLER ASSEMBLY SHOWN REQUIRES
A 90 DEGREE CLOCKWISE ROTATION TO TURN

ON

 (I.E., COTTER PIN TO THE RIGHT).

IF COUPLER ASSEMBLY RESTS AGAINST STOP
PIN #1 WHEN HANDLE OFF, ASSEMBLY WOULD
REQUIRE 90 DEGREE COUNTERCLOCKWISE
ROTATION TO TURN 

ON

 (I.E., COTTER PIN TO

THE LEFT).

HANDLE IS ON WHEN FLAT SIDE IS TOWARD
EITHER LEFT OR RIGHT SIDE

BATTERY IS ACTUALLY ON WHENEVER FLAT
(BEVELED) SIDE OF SHAFT IS FACING ANY
DIRECTION EXCEPT DOWN.
