  • Page 23: Control Head

    4.2 Control head Introducing the control heads In order to inform the control about the number of control heads connected, these must be introduced. For twin engine controls with mechanical throttle control and gear shifting, the procedure has to be carried out at the portside system.

    Synchronising Synchronising active If the lever positions of the port and starboard control heads CTRHEAD deviate at 10% maximum, the same nominal value will be preset automatically. No synchronizing (default condition) CTRHEAD 4.3 Speed setting Generally, the parameters for speed setting can be set when the active control head is in neutral position.

Change to SETUP-mode PARSEL LED Setup The selected position will be reached.

  • Page 28: Gearing

    4.4 Gearing Positions for actuating the mechanical gear shifting The push-/pull-cables at the actuators must be mounted in such a way that the neutral position of the gear system is actuated when the active lever is placed in neutral. For systems configurated with 2 control units (mechanical throttle control and gear shifting) each control unit must be set separately.
  • Page 29 During step 4, it is possible that the gear position adjusts automatically, the driving engine should therefore be turned off. Change to SETUP-mode PARSEL LED Setup The selected position will be reached. LED Setup will be activated. Adjusting the gear position PARSEL Direction + Position is adjusted as long as the key is pushed.
  • Page 30 Conditions when reversing from ahead to astern: When reversing from ahead to astern, the gearing is at first shifted to neutral, the shaft is disengaged from the engine (1). As the ship continues to move ahead, the propeller is driven like a windmill by the water streaming against it so that the shaft continues to turn.

  • Page 31: Reset To Default

    4.5 Reset to default Resetting to default will reset the speed and gearing control values to their delivery status. This procedure is irreversible. A reset to default may be done only if the driving engine is turned off. In case of mechanical controlling, the push-/pull-cables should be disconnected.

  • Page 33: Activation And Request Control Station

    5.2 Activation and request of control station After switching on the power supply, all control heads which work correctly are in condition "lamp test" (all lamps and buzzer on). The command can be requested from every control station by pressing the key once.

  • Page 34: Station Transfer

    5.3 Station transfer A command transfer is possible in 2 different modes. Which mode is applicable, depends on the position of switch 3 on the switch board CTRHEAD (see chapter 4.2 control head – comparision of range / position). Always, the key on the passive control station must be pushed to change the control station.

  • Page 35: Warming Up

    5.4 Warming up By means of the special function "warming up" a determined speed can be set without gear shifting. This function is necessary to warm up the engines. To activate "warming up", the key must be pushed at the active control station and, at the same time, the lever moved in ahead or astern.

The operation mode of the control is indicated by 2 additional LEDs (RUN, SETUP). By pressing a key, further error messages can be displayed.
  • Page 38 Error type: ACTUATOR 1 Error description: The system is configurated ( see chapter 2) in such a way that actuator 1 (see chapter 3.3) directs mechanical gear shifting or speed setting. However, the control states an error in the operation of the actuator. Error elimination: Check the plugs of actuator 1 for correct connection to the board of the control unit (see chapter 3.3).
  • Page 39 Red LED 1 flashing Error type: SYN-CARD (warning only) Error description: No extension board for synchronizing found. Error elimination: Check cable from synchronizing board to board of the control unit (see instructions attached to the synchronizing board). If necessary, replace synchronizing board. Error type: SYN-SIG (warning only) Error description: The synchronizing board cannot measure the speed correctly.

  • Page 42 Error type: CTRL-POS Error description: Before adjusting parameters for speed and gear control, the active control head must be placed in the correct position (see chapter 4.3 or 4.4). It is not permitted to adjust the parameter in this lever position. Error elimination: Change to RUN-mode (step 1 in chapter 4.3 or 4.4).
