Page 262 ELECTRICAL INTERLOCKS The 7100 has several interlocks which can inhibit or cancel machine functions. D REVERSE − If the board does not sense an active forward sense (P4−6) or neutral sense (P4−12), the controller board will assume reverse. When this happens the following function will become inhibited: −SQUEEGEE will rise.
Page 263 ELECTRICAL D FULL RECOVERY TANK − The 7100 will cancel the following functions if the recovery tank float switch is turned on: THE CONTROLLER will cancel scrub and squeegee operations, as if someone toggled the scrub or squeegee buttons. THE TANK FULL LED will start to blink. This message will not turn off by simply emptying the recovery tank.
