BELT BREAK PROXIMITY SWITCH – FUNCTION 4
It is recommended that the belt break proximity switch be installed with a 15 mm clearance with the switch
sense facing the spring loaded idler pulley (metal). If the engine cooling belt breaks, the idler pulley will
return to its rest position. The switch should be located so as to lose proximity with the pulley when the belt
breaks.
