Automatic Closing After Stop; Automatic Closing After Photocell Activation; Automatic Closing After Vehicle Loop Activation; Direction Sensing For An Internal Closing Pulse - DAAB EP104 Instruction Manual

Automatic closing after stop

All control signals except stop and power failure restart the countdown for automatic closing. This means that automatic
closing is not affected in the event of a stop signal. This applies to conventional inputs and to programmable inputs.
If you want the countdown to restart automatically even after a stop signal is received, you must set a delay in channel C520
as well as C500 or C501.
Select channel C520 and set a 0.20 - 9.59 minute delay for automatic closing after stop has been activated. Set the value to
0.00 to disable automatic closing.

Automatic closing after photocell activation

This function enables automatic closing after a photocell is activated.
Use channel C351 to activate the function.
Select channel C351 and set the value to 1 to activate or 0 to deactivate.
Use channel C354 to specify how the door closes once the photocell is no longer activated.
Select channel C354 and set the value to 1 to close immediately, or 2 to close only after opening fully.
To delay closing after photocell activation, select channel C510 and set a time between 0 and 99 seconds.
Note that the delay configured in channel C510 is also used for automatic closing after the vehicle loop is activated.
If the photocell is not activated, automatic closing occurs as described above.

Automatic closing after vehicle loop activation

This function enables automatic closing after the vehicle loop is activated. The function is present on both loops, but is
shown below for loop 1.
To access the function, select channel d151.
Select channel d151 and set the value to 1 to activate or 0 to deactivate.
Use channel d154 to specify how the door closes once the photocell is no longer activated.
Select channel d154 and set the value to 1 to close immediately, or 2 to close only after opening fully.
To delay closing after loop activation, select channel C510 and set a time between 0 and 99 seconds.
Note that the delay configured in channel C510 is also used for automatic closing after a photocell is activated.
If the vehicle loop is not activated, automatic closing occurs as described above.

Direction sensing for an internal closing pulse

Using channel C591 and the DB402 add-in card for vehicle loops, you can configure the internal close signal depending on
the preferred direction sensing mode in LOOP1 and LOOP2 and the PHOTO input.
See the channel reference for all possible values.

• Run-on times, mechanical limit switches and timer control

See also "Stop function with run-on time" below to define how the stop function works during the run-on time.
The benefit of run-on times is that the limit switch does not need to be set precisely – you can fine-tune the end position using
the run-on time. This avoids the need to climb up to the motor winder to adjust the limit switch. You can also use the run-on
time if you want a door to close securely against the frame without triggering the load guard or safety edge.
NOTE! The run-on time must never be set if there is a risk that the limit switch cam can bypass the switch.

Reverse during run-on time

To change how the unit operates during the run-on time, set channel C448 to the desired function.
Factory setting 2, Safety edge reverse during run-on time and during the time in C492.
Set C448 to 0 to allow the unit to be operated without the safety edge function during the run-on time.
For other options, see the channel reference.

Run-on time for closing

Stopping with a run-on time means that when the limit switch close is activated, the door continues for a specified time.
Select channel C423 for motor 1 and channel C433 for motor 2, set the required run-on time in seconds.

Run-on time for opening

Stopping with a run-on time means that when the limit switch open is activated, the door continues for a specified time.
Select channel C422 for motor 1 and channel C432 for motor 2, set the required run-on time in seconds.

Stop function during run-on time

Select channel C436 and choose the stop function you want during the run-on time. The function specified in channel C436
is only active during the run-on time for closing. Depending on the stop function configured in C436, you can set the door
to close tightly against rubber strips without triggering the load guard or safety edge.
NOTE! Channel C436 is subordinate to channel C448, safety edge reverse during the run-on time, see "Safety edge".
There are four options for the stop function during the run-on time in the closing movement – channel C436 0, 1, 2 or
3 – but safety edge reverse during the run-on time must be disabled in channel 448.
