Assembly and Operating Instructions

Automatic Closing

A switch can be connected across terminals

A12

and

B12

(AUTO/WZL) in order to activate the

Automatic Closing function

If Automatic Closing is activated, the door is closed by the control unit after the automatic closing time (time Z4 = 60 s) has
elapsed. If the Early Warning function is activated (DIP switch 1.6 in the ON position), before commencing the automatic clos-
ing procedure an early warning is given by actuating relay 1 with an early warning time Z3 = 3 s.
By attaching the timer module to system plug X1 of the MLS Professional Card III, the reclosing time can be variably set be-
tween 2 and 240 s.
For a description of the timer module, see „Timer Module Technical Information“

Photoelectric Barrier (MLS Professional only)

A photoelectric barrier can be connected across terminals

and

(PB). For installation the wire jumper across terminals

and

must be removed.

This control input has two functions:
• If the photoelectric barrier responds during downward movement (Fault2 lamp flashes), the door stops instantly. After an

internal time of 0.5 s (time Z0) has elapsed, the

S80

opens the door again. Depending on the setting of DIP switch 1.3, the

control unit moves the door clear of the obstacle or to the top end limit.

• If the door is open or being opened and the light beam is interrupted and then released again, the automatic closing time

is reduced to 3 s in the event that DIP switch 1.8 is in the

position. If DIP switch 1.8 is in the OFF position, the auto-

matic closing time Z4 will run again.

Safety Edge (MLS Professional only)

The following safety edge systems can be connected to door control unit S80 directly:
•  Pneumatic safety edge or
•  Electric safety edge or
•  Optoelectronic safety edge: FRABA OSE
The sensor required is integrated into the control unit (self-monitoring sensor as per pr EN 12453). The pneumatic safety edge
or the electric safety edge is connected up to terminals

and

(SKS/USA). To ensure that the spiral rubber-insulated

cable is monitored, the 1.2 kW resistor clamped across terminals A6 and B6 is supplied with the unit. It must be connected
inside the pressure switch contact or at the end of the electric safety edge in accordance with the wiring diagram for the S80.
In the case of factory-assembled electric safety edges, check their terminating resistance. Safety edges with a 1.2 k

Ω

or 8.2

Ω

terminating resistor may be used. Connect the OSE optoelectronic safety edge made by FRABA to terminals

and

(OSE) direct without the need for any terminating resistor (

- brown wire,

- green wire,

- white wire). To adapt the

control unit to the respective safety edge, set DIP switches 1.1, 2.1 and 2.2 according to the following table.

Caution
When using optoelectronic safety edge FRABA OSE DIP switch 2.1 must always be set to the OFF posi-

tion or else the self-monitoring system of the sensor integrated into the control unit will be deactivated.
If a pneumatic switching rail is used, DIP switch 1.1 must be set to the ON position, as otherwise the func-

tion of the pneumatic rail will not be correctly monitored. When delivered, safety devices may be bridged.

Before initial use, always check that no non-permissible bridging exists.

If the safety edge responds during downward movement (bottom rail sensor LED

SKS/USA

lights up), the door is stopped

instantly by the S80 control unit. After an internal time of 0.3 S. (time

) has elapsed, the

S80

opens the door again.

Depending on the setting of DIP switch 1.3, the control unit moves the door clear of the obstacle or to the top end limit.
