Self-diagnosis of the main controller and the system
The controller has extensive diagnostic features. Directly after switching on and during operation, the diagno-
sis is carried out continuously.
Cable interruptions, short circuits and undefined states
Cable interruptions of the inductive end position sensors, the proximity switches of the actuators (upright,
rotary arrow or bolt motor) as well as of the lights (directional emitter and long range warning) are detected.
In addition, undefined states (e.g. both end position sensors active) are also detected and displayed accordin-
gly. In certain cases, the light arrow is switched off.
Further error indications
After switching on, in addition to the previously described defects, further malfunctions are displayed via the
LED of the remote control:
Lamps faults:
the keys „Arrow Right“, „Arrow Left“ and „Cross“ flash yellow or red if there is a cable interruption, a short
circuit or defects of the LEDs in these lamp.
Proximity switches
of the lifting / lowering actuator:
LEDs of both buttons (UP/DOWN) flash red, cable interruption or
undefined state
Proximity switches
of the rotary arrow:
LED on key “ON” flashes yellow: cable interruption or undefined status
Overvoltage / Undervoltage
The on-board voltage (12V or 24V) is automatically recognized by the controller after switching on.
Undervoltage control reaction (12V on-board power supply):
under 11,6 V Warning
under 11,2 V Arrow board is switched off, only MS 340 lamps keep flashing
under 10 V Complete system is shut down
Overvoltage control reaction:
higher than 16 V Complete system is shut down
Undervoltage control reaction (24V on-board power supply):
under 23,2 V Warning
under 22,4 V Arrow board is switched off, only MS 340 lamps keep flashing
under 20 V Complete system is shut down
Overvoltage control reaction:
higher than 32 V Complete system is shut down
CAUTION!
The self-monitoring of the security system does however not release you from the duty to con-
stantly ensure that it is functioning properly. This is done by observing the remote control and the
indicators fitted on the housing of the main control unit.
Especially in case of a defect of the microprocessor, error states are likely to occur which do not
cause any warning by the signal horn or the remote control. If the continuous observation is not
carried out, accidents with possibly fatal results may result.
Repairs and maintenance
CAUTION!
Repair and maintenance works should generally only be carried out by qualified
personnel or if possible by the manufacturers on site
„Information for the expert /technical engineer“.
Complete breakdown
Please check:
- the battery terminals
- fuses (on-board)
- the supply voltage at the plug contacts of the main circuit board
- LED indicator lights on the control board (from right to left):
LED 1 lights up: power supply is provided
LED 1 and 2 light up together: power supply provided, CPU is switched on or active
If no error has been detected up to this point, please contact our customer service
Softwareupdate
The software of the main control unit can be installed via the USB socket.
The control unit must be disconnected from the on-board power supply beforehand.
Now connect the control unit to the computer using a standard USB-B connection.
During the update, only LED 2 lights up if no power supply is connected.
Replacing the main circuit board
- disconnect the current supply at the rechargeable battery (first the negative and then the positive pole),
- open the enclosure of the maincontrol - disconnect the power supply cable by removing the flat plugs
- disconnect the multipoint connectors on the circuit board as well as all actuators, making sure that the main
circuit board is not subject to any mechanical stress during this process! If necessary, create counter pres-
sure at the position by holding the board firmly
- loosen the fixing screws of the circuit board and remove it
The installation of the main circuit board is carried out in reverse order.
