The Remote Lockout system is equipped with an option to operate as either a hydraulic

after lockout, turn ignition key to ON, select RUN mode, and wait for the solid green light, then turn ignition
key to start position.

pressures are monitored. If any of the hydraulic pressures increase, or if drilling fluid system is turned on,
engine will be shut down. The engine cannot be restarted until Run Button is pushed.
