HOME PROXIMITY SWITCH -
This proximity switch is used during the initial installation
and set-up of your M&R Challenger Series II press. The
Home proximity switch is used in conjunction with the Index
Servo Drive to “teach” the servo drive where the optimum
starting reference point for the index drive assembly is
located. The Home proximity switch is used only for the ini-
tial installation of the system, or when ever the servo drive
assembly or its components have been replaced. This prox-
imity switch is not actively used during normal operation.
The switch is located on the left side of the index drive
assembly. (See illustration at left)
