2. Use of HMC 542
2.1. Installation
HMC542 is to be connected according to the wiring diagram to the power supply, sensors and actuators
of the chipper
2.2. Switch on and off
The HMC 542 is switched on with the key start (turn to position 1). The chipper can be started after the
preheat time (turn to position 2). After start of the engine, the chipper speed is displayed (see at 3.1).
To stop the and the chipper and switch off the HMC542 turn the HMC542 into the Position “0”
HMC542 has to be connected permanent to the battery + to enable the storage of parameters like running hours after the engine was stopped.
2.3. SET-button
If you want to change settings on the device, hold the SET button pressed, while the ignition key is turned
into position 1, until the field of code entry appears. Each digit of the code has to be confirmed by pushing
the SET button. In addition, you need the button to get in the sub-menus of programming or display mode
and to quit your entry .
2.4. Arrow buttons
In normal operation, the arrow buttons are used to increase and to decrease the engine speed (RUN and
IDLE.
In the parameterization mode, use the arrow keys to navigate the various settings in the main and submenu and in the "selection / input" (see table in paragraph 3.2). In addition, use the arrow keys to enter
the digits in the code and for reducing or increasing a value of the parameters.
3. Change of settings
If you want settings different than the factory defaults settings, the HMC 542 can be programmed after the
initial installation. If you want to make such a change, please contact the manufacturer of your chipper
To enter the parameterization mode, press the SET button while the ignition key is turned into position1,
until the field for entering the codes appears.

3.3. Further adjustments and explanations
3.3.1. How to reset the total hours counter
To reset the total hour meter push the SET-button while turning the key start in position 1. Afterwards
enter the code 9191. If you confirm the code with the SET-button the total hours are deleted.
3.3.2. Energized to run solenoid (ETR)
This solenoid releases the fuel supply and has to be triggered while the engine is running.
3.3.3. Energized to stop solenoid (ETS)
This solenoid has to be triggered to stop the engine. If you turn the key start in position “0”, the solenoid
will be triggered for 20 seconds. After the engine is stopped, the HMC 542 is disconnected from power
supply.
3.3.4. How to set engine speed values
The setting of the speed values with the help of four parameters, guarantees the stable operation of the
engine. The following overview of the scheme should serve faster understanding:
The rated speed is the speed at which the feeder is switched on.
If during the operation speed gets below the minimum speed, the feeder is stopped. The engine will increase the speed because the load is reduced. When the return speed is reached, the feeder will start
again.
If during the operation the speed exceeds the maximum speed, the feeder is stopped also. When the
rated speed is reached, the feeder will start again.
