The tamper may be mounted with or without self-adjusting externder screw
in place. With the extender screw removed, plunger will recede flush to housing.
Mounting Instructions
Locate switch so that removal of covering plate or door will allow the
plunger to be fully extended. Plunger travel (fully extended to fully depressed) is
approximately 3/16". Mount switch with three 6 x 1 screws (provided). When
pre-drilling for screws is necessary, use .100" bit (#39). To increase reach of
plunger, thread extender screw into switch 1/4". Closecovering plate or door.
Extender will slide inward to accommodate opening. The extender screw can also be manually
adjusted with a screwdriver.
When servicing equipment with closed loop model (3025T), the effect of
having the plunger depressed (i.e. closed loop)can be simulated by gently pulling plunger
outward into locking position.
