4.5 Connecting additional components

Note

The complete accessories can load the operator with max.

100 mA.

4.6 Connecting external IMPULSE buttons* to start or stop

door travel cycles

One or several buttons with closer contacts (floating),

such as internal buttons or key switches, is/are connected

(then parallel) as follows (see fig. 9):

1) first contact to terminal 21 (impulse input).

2) second contact to terminal 20 (0 V).

4.7 Connecting indoor button IT3b (see figure 10)

An indoor button IT3 is connected as follows:

1) Contact + to terminal 21 (impulse input).

2) Contact – to terminal 20 (0 V).

4.7.1 Connecting external IMPULSE button to start or stop

door travel cycles (see figure 10.1)

4.7.2 Light button: switch on / off operator lightning (see

figure 10.2)

4.7.3 Button: switch on / off radio system (see figure 10.3)

4.8 Connecting a cutout switch or a wicket door contact

(must feature forced opening) to stop and/or

cut off the operator (STOP or emergency-OFF

circuit)

A cutout switch with opener contact (floating) is connected

as follows (see fig. 11):

1) Connect the floating opener contact to terminals 12

(STOP or emergency-OFF input) and 13.

2)Set DIP switch 1 (SCH1) to OFF.

Note

By opening the contact any possible travel cycles are

immediately halted and permanently prevented. The

operator lighting signals the impulse code 1x flashing and LED 4

flashes.

4.9 Connecting a photocell* to initiate a safety return up to

the "OPEN” end-of-travel position

A photocell (safety device) that has a floating opener

contact is connected as follows (see fig. 12):

1) Connect the floating opener contact to terminals 71

(safety input) and 20 (0 V).

2) Connect terminals 5 (approx. + 24 V) and 20 (0 V) to

the voltage supply.

3)Set DIP switch 2 (SCH1) and DIP switch 1 (SCH2) to

OFF.

Note

If during the closing cycle the photocell is interrupted, the

door reverses and travels to the "OPEN" end-of-travel

position. If the automatic timer is activated, the time is

reset, i.e. as soon as the photocell is clear again, the set

time phase restarts. The connection is only active during

the closing cycle. The operator lighting signals the impulse

code once 1x flashing and LED 4 flashes.

4.10 Connecting a 2-wire light barrier* to initiate a safety

return up to the "OPEN” end-of-travel position

A 2-wire light barrier is connected as follows (see figure

13):

1) Connect the contact RX or TX to terminal 71 (safety

input) and the contact 0V to terminal 20 (0 V).

2) Set DIP switch 2 (SCH1) to OFF and DIP switch

1 (SCH2) to ON

Note

If during the closing cycle the photocell is interrupted, the

door reverses and travels to the "OPEN" end-of-travel

position. If the automatic timer is activated, the time is

reset, i.e. as soon as the photocell is clear again, the set

time phase restarts. The connection is only active during

the closing cycle. The operator lighting signals the impulse

code once 1x flashing and LED 4 flashes.

4.11 Connecting an optical protection of closing borders

8,2kΩ*

A protection of closing borders (safety device) with 8,2kΩ

resistance is connected as follows (see figure 14):

1) Remove the connected 8,2kΩ resistance

2) Connect the protection of closing borders to the

terminals 74 (safety input) and 20 (0 V)

3) Set DIP switch 2 (SCH2) to OFF.

Note

If the light barrier is activated during the closing of the door the

door reverses in position „open“. In case of automatic closing

the the opening time is set back – after leafing the light barrier

time starts to run out from the beginning.

The light barrier is only active during the closing of the door.

The operator lightning flashes 1x and LED 4 flashes.

4.12 Connecting an optical protection of closing borders*

A protection of closing borders (safety device)

optosensors (Fraba) is connected as follows

(see figure 15):

1) Remove the connected 8,2kΩ resistance

2) Connect the protection of closing borders to the

terminals 77 (+12 V), 74 (safety input) and 20 (0 V)

3) Set DIP switch 2 (SCH2) to ON.

Note

The input is active during the closing cycle. During the closing

cycle door reverses and travels to the "OPEN" end-of-travel

position. The operator lighting signals the impulse

code once 1x flashing and LED 3 flashes.

4.13 Connecting a warning light* to the optional relay

A warning lamp with max. 230V~/300W can be

connected to the floating closing contact terminal 1 and

2 (KL1) of the optional relay (see figure 21). The

warning light is on during every door cycle and flashes

during the warning time of “automatic closing”. Set DIP

switch 6 (SCH2) to OFF.

4.14 Connecting an external lamp to the optional relay

An additional external lamp with max. 230V~/300W can

be connected to the floating closing contact terminal 1

and 2 (KL1) of the optional relay (see figure 22). The lamp

is switched parallel to the operator lighting. Set DIP switch

6 (SCH2) to ON.

4.15 Connecting a “door closed” display to the optional

relay

An external “door closed” display with max. 230V~/300W

can be connected to the floating closing contact terminal

1 and 2 (KL1) of the optional relay (see figure 23). The

optional relay is activated during the end-of-travel position

“door closed”. Set DIP switch 8 (SCH2) to ON.
