INSTRUMENTS AND CONTROLS ELECTRONIC MONITOR & CONTROL CONSOLE (EMACC) This monitor system consists of monitor lamp groups (@, @, 01, meter group @ and switch group 0. @CHECK MONITOR GROUP (Check items before starting) If there is any abnormality, the appropriate monitor lamp will flash. Check the location where the monitor is flashing, and carry out the Checks before starting. * When the engine is started, these monitor lamps will go off even if there are abnormalities. @CAUTION MONITOR GROUP (Caution items) If any abnormality occurs while the engine is running, the appropriate monitor lamp will flash to indicate the abnormality.
* Even if any monitor lamp flashes, the machine can operate, but it should be repaired as soon as possible. @CAUTION MONITOR GROUP (Emergency caution items) If any abnormality occurs while the engine is running, the appropriate monitor lamp will flash and the alarm buzzer will sound intermittently at the same time. * If any monitor lamp flashes, stop the work, and repair it immediately. @METER GROUP This group consists of engine water temperature gauge, fuel gauge, engine pre-heating monitor lamp and swing lock lamp. @SWITCH GROUP This consists of the lamps, car heater, mode selector switches, wiper switch, alarm buzzer stop switch and travel speed switches.
Functional check of the machine monitor system When the starting switch is turned ON before starting the engine, all the monitor lamps and the gauges light up and the alarm buzzer sounds for about 3 seconds. If any monitor lamp does not light up, there is probably a broken bulb or disconnection in the monitor, so ask your Komatsu distribu- tor to inspect it. * Park the machine on level ground and check the monitor lamps. -6-
