Mains connection
The control unit comes ready-wired with a 16A CEE
phase-changer plug and approx. 1 m of cable (see
4a
).

Observe rotating field.
Mains isolator
A mains isolator is provided for
disconnection of all poles of the mains
voltage. Secure the mains isolator against
unauthorised use during maintenance
or repair.
Connection of hydraulic motor

Valve connection
A sensor and limit switch for the automatic return
function can be installed besides the valve
connection.
6
Emergency stop button
Remove the jumper and connect the emergency stop
button. Pressing the emergency stop button stops
the dock leveller, no free floating position.
7
Sensor zero position
Required for combined operation with mutual
interlocking (menu 17=0). The door can only be
closed at zero position.

Key switch connection
When using a key switch, the desired function in
menu 50 should be selected.

Relay output
2 change-over contacts:
max. 250VAC / 2A or 24VDC / 1A.
24V-output X8:
max. 100mA
Selecting the relay function in menu 45 and 46.
11
Motor connection
Connect the motor to agree with the available mains
voltage. Also see fig. 4.
12
Motor connecting lead
The connecting lead for the motor and digital limit
switch (DES) is pre-assembled and ready to use -
attach accordingly.
13
Impulse generator connection
If the door is to be opened and closed via a
select value 1 in menu 51.
14
Photocell connection
The photocell must be correspondingly set / adjusted
in menu 36.
14a
Two-wire photocell LS2
During this process the closing
procedure must not be interfered with,
otherwise the wrong position could be
recorded.
14b
Four-wire photocell LS5 with self-testing
14c
Reflection photocell RLK29
If in the menu the frame-fitted photocell has been
selected, the next time the door closes the control
unit automatically initiates a learning run to detect the
can
position.
15
Safety edge connection
When using impulse control for door closing,
connection of a safety edge is required. Select the
corresponding setting in menu 35.

Electrical safety edge 8K2 with a termination
resistor of 8.2 kOhm

Radio remote control
Plug in receiver module (option) at J11 and initiate
the hand transmitter learning procedure in menu 60,
61 or 62.
Programming the control unit
Programming is menu-driven. Make all settings as
shown in the schematic.
Protected settings are identified by the letter
display and access to the menu is barred. To release
the menu, the release signal must be sent with the
infrared control.
Hydraulic motor overcurrent (menu 10)
If the set overcurrent is exceeded, the control will
switch off the pump.
Automatic time (menu 13)
When the return button is pressed, the dock leveller
is lifted for the time set and then lowered safely to
zero position.
Automatic return (menu 14)
When button
is released, the lip retracts for the set
time to correct the position.
Dock leveller – door operation options (menu 17)
The control for initial start-up in menu 17 = 4 is set to
dock leveller operating mode. The respective
function should be set as soon as the door is started
up.
Make sure that the door and the dock
!
leveller cannot crash.
Correcting the slowing-down path (menu 42)
Compensates changes in the closed position
resulting from temperature fluctuations, gearbox run-
in etc.
Level adjustment (menu 43)
Compensates changes in the closed position
resulting from cable elongation or a rise in the floor
level. Set the precise closed position beforehand,
then set in menu 43.
Spring breakage detection (menu 47)
The deviation in the opening and closing movements
is compared with the set value. If the set value is

button,
exceeded, error E32 is displayed.

After the springs have been renewed,
the door end-of-travel positions need to be reset.
Motor 9.24: input value = U x weight / 20 kg
Motor 9.20: input value = U x weight / 16 kg
Motor 9.15: input value = U x weight / 15 kg
Example:
Motor 9.24, U = 8 revolutions to open the door
Weight of the door leaf = 150 kg, each of the 2
springs bears 75 kg. Cut-off recommended at 60 kg.
Input value
= 8 x 60 kg / 20 kg =
The quick release requires re-setting,
otherwise spring fracture safeguards
must be connected.
Check of the spring balancing device
Press the button
only briefly, after the door has been completely
opened and closed once.
The value indicates how the door is balanced:
Motor 9.24: F (kg) = display value x 20 kg / U
Motor 9.20: F (kg) = display value x 16 kg / U
Motor 9.15: F (kg) = display value x 15 kg / U
U = number of revolutions for one door opening
If the display value ranges between -2 and -9, the
springs are over-tensioned.
The results are only approximate values; a force
measuring run is required to determine the value
more precisely.
Opening force limit (menu 48)
The door's opening movements are compared with
one another. If the set value is exceeded, the door
stops and F33 is displayed.
Thereafter, the door can only be closed via the
!
dead man's control. Eliminate the reason
for the excessive force being applied, so that
the door can be opened and closed again.

Force measuring run
to determine the cut-off threshold.
After value 99 has been entered in menu 48, the
control will carry out a force measuring run:
1. Attach a test weight (recommended approx. 20
kg) at the door and open and close the door
completely.
2. Following that, menu 48 displays the value
which will be imported as cut-off value. This
