Switching on and off
Use the ignition starter switch (position 1) integrated in the controller with active terminal 30 to switch
on the HMCflex unit. You can start the engine (position 2) when the pre-glow time has elapsed. In this
manner, you directly reach the operating mode in which the speed, operating hours, oil pressure and
engine temperature (or only the "OK" state, if selected) are displayed. Use the arrow keys to switch to
display the daily and total operating hours.
Use the ignition key to switch off the engine and the HMCflex unit. The HMCflex will automatically run

Programmed faults (alarms) are indicated by a flashing warning light and full text on the display. The
display toggles between fault and operating parameter display.
The device must be connected to steady plus (terminal 30) for the correct retention of data and set-
tings.
After the HMCflex has been switched on, the following screen is displayed for a short time. It provides
