As the machine accelerates to extract speed the balance board monitors accelerometer amplitude
inputs and photo-eye timing inputs to detect the rapid excursions which occur when a machine is
out of balance. If the balance board determines that inputs exceed the predetermined limits, the
board signals the microprocessor to limit machine speed. For additional information see
“BICWPF02...Speed Limiting on 42032 F7S and 36030 F8S Open-pocket Staph-
Guard

Models,” in the reference manual. These instructions explain how to install the
accelerometer and balance board then complete the required electrical connections.

This retrofit kit contains one electronic balance board and plastic shield, one accelerometer, one
15' length of shielded, four connector wiring harness, three pre-wired and stamped MTA
connectors, along with three MTA pins, an empty four pin MTA connector and mounting
hardware for the accelerometer and balance board.
Technicians installing this kit must be able to read Milnor wiring diagrams, thread a harness
through conduit, and make electrical connections.

This retrofit kit requires personnel to work inside electric boxes of both high and low voltage.
Make machine safe for personnel prior to starting procedure.
Contact with high voltage
will electrocute or burn
y
ou. Power switches on the machine and the control box do not eliminate
these hazards. High voltage is present at the machine unless the main machine power disconnect
is off.
Lock out and tag out power at the main machine disconnect before servicing, or in
accordance with factory service procedures.
Do not service machine unless qualified and authorized.
1.
Lock out and tag out power
at the wall disconnect box.
2. Verify that the software chips in the balance and processor board are the latest versions
(Table 1). See BICWPF02...Speed Limiting on 42032 F7S and 36030 F8S Open-pocket
Staph-Guard
