5. Mains connection
The control is wired in a ready-to-connect fashion using a
16A CEE plug and a cable with an approximate length of 1m in
compliance with Fig.
a
. Connect the control via an all-pole line
disconnecter ≥ 10 A complying with the specifications of
EN12453 to the house wiring system. In doing this, ensure that
the line disconnecter is easily accessible after the installation.
NOTICE
Checking the mains connection
• Ensure that on-site fusing of 10 A is avail-
able.
• Check whether the mains connection on
site complies with the pre-wired mains con-
nection of the control.
• If the mains connection shows any devi-
ations, the control must be rewired.
6. Motor connection line
Fig.
a
The motor connection line is pre-assembled for the motor
and the digital limit switchDES. The connection is implemented
by fixed cable routing of the motor connection line and using cor-
responding connectors. A digital limit switch complying with PLc
as per EN13849-1 must be used (DES3, DES4).

b
Spring fracture safety device / roll-down locking mech-
anism
If a spring fracture safety device is tripped, the control must be
protected against restart by spring fracture or roll-down safety
switches. The switches must be used as normally closed contact
subject to forced actuation complying with EN 60947-5-1, An-
nexK. With fixed cable routing, the switches are connected to the
terminal board of the DES.
7. External command transmitters
If you connect external command transmitters to terminal J1 of
the control, the following variants are provided:
Fig.
a
Connection to J1 for external three-button keys.
Remove jumper J1.1/2.
Remove the jumper at J1.1/2 and set menu item 51 to the
value1.
Fig.
b
Connection to J1 for key switch OPEN-CLOSE.
Set menu item51 to the value0 (default setting).
Fig.
c
Connection to J1 for external pulse generators with an
OPEN-STOP-CLOSE switching sequence
Set menu item51 to2.
CAUTION
Crush hazard and risk of being struck by the
closing door
Persons can be struck when the door is closed
or collide with the door.
• Mount external pulse transmitters always
within the range of view of the door.
• The door must be visible from the place of
operation.
NOTICE
Dead man mode only with key switch
Dead man mode only with key switch for access
by non-instructed persons
8. Photoelectric sensor
Connect the photoelectric sensor as specified for the following
variants:
Fig.
a
2-wire photoelectric sensor LS2
Fig.
b
4-wire photoelectric sensor LS5 with testing
Fig.
c
Reflection light barrier
Then select the corresponding photoelectric sensor under menu
item36.
If you have selected the value3 "Photoelectric sensor mounted in
the frame", the next CLOSE run executed by the control is a
"learning cycle" for detecting the position.
This learning cycle is indicated by the valueE10 in the LED dis-
play.
NOTICE
Do not interrupt the learning cycle
The learning cycle must not be interrupted, so
that no incorrect position is recorded.
9. Door connection box
Fig.
a
The door connection box allows for the connection of a
safety edge, a wicket door contact and slack rope switches. The
wicket door contact and the slack rope switches are electrically
connected in series and are monitored by the control. If a wicket
door is available, the wicket door contact (Entrysense 6k8 model)
is connected to the door connection box. For this purpose, re-
move the 2kOhm resistor from the door connection box, to which
the Entrysense is clamped, and connect it there. The Entrysense
is tested in compliance with PLC as per EN13849-1 and is mon-
itored by the door control.
As slack rope switches, switches with forced actuation complying
with the specifications of EN60947-5-1, AnnexK are to be used.
The supply line of the door connection box is to be laid at the
door leaf, well protected against damage. With pulsed operation,
connect a closing edge safety device and select the correspond-
ing setting in menu item 35. Pressing the Prog button in
menu item35 for a longer time displays the measured resistance
value of the 8k2 closing edge. Example: Value 82 means 8k2.
Pressing the Prog button briefly will interrupt the display.
CAUTION
Crush hazard and risk of being struck by the
closing door
The pressure wave switches may only be actu-
ated after having been tested.
• For this purpose, select the value2 in menu
item35.
10. Radio receiver
For the use of a hand-held transmitter, attach the receiver module
(option) to J5 (Fig.
a
) and connect the antenna to J4. In order to
program the hand-held transmitters, follow the instructions
provided in Programming a radio hand-held transmitter in the
Programming chapter.
11. Relay outputs
Fig.
a
The control provides a change-over contact, max.:
250VAC / 2A or 24VDC / 1A.
The 24V output at terminalX4 may be loaded with a maximum of
150mA.
Select the desired relay function in menu item45.
