Product Overview
The Bobcat Interlock Control System uses the seat-bar signal as one of the conditions for enabling machine functions. If the sensor fails or its wiring is damaged, the loader can behave as though the restraint bar is still raised even when the operator has lowered it.
Parts references identify 6691714 as a seat-bar BICS sensor and show 6680429 as an earlier number. Because interlock systems are safety-critical and model/serial changes exist, the sensor number should be matched to the machine parts catalog rather than bypassing or defeating the circuit.

Frequently Asked Questions
Can a bad seat-bar sensor stop hydraulic functions?
Yes. The interlock controller may withhold function enable if it does not receive the expected restraint-bar signal.
Should the interlock be bypassed for testing?
Follow the service manual and approved diagnostic procedure. Permanent bypassing of operator-safety interlocks is unsafe.
Compatibility can vary by engine, serial number and equipment configuration. Match the original part number and physical configuration whenever possible before ordering.
