DAAB EP104 Instruction Manual page 26

• PHOTO input
The EP104 has a PHOTO input for use with a photocell or a vehicle loop via an external control unit, see "Signal reference".
To connect both devices to the same input, connect them in series via potential-free contacts.
PHOTO input in the closing movement
When a vehicle passes the photocell or vehicle loop during the closing movement, the door usually reverses to the fully open
position. To prevent vehicles sneaking in while the door reverses, you can instead set the door to stop and then close after
the automatic closing time by setting C340 to 2 and C500 to a suitable delay.
PHOTO input in the opening movement
If a vehicle passes the photocell while the door is opening, nothing usually happens. It is possible to set the door to stop
instead, then close after the automatic closing time when the photocell is clear. However, this setting would prevent reverse
in response to an activated photocell during the closing movement.
The door can either close again when the photocell or vehicle loop is clear, or stop while the photocell is activated and then
close when the photocell is clear, according to the setting in channel C342.
• Limited running time
Limiting the running time can protect the equipment from possible damage caused by a fault. The time should be set slightly
longer than the normal running times for opening and closing.
In hold-to-run mode there is no limited running time, so this is a good way of measuring the running time.
Use hold-to-run mode to operate the door from fully closed to fully open and the other way around, read off and note the
running times from C401 for motor 1 and C402 for motor 2.
Select channel C403 and enter a value about 3 seconds longer than the longest time measured.
• Checking LED indications
Before continuing the commissioning process, check that all LEDs are working correctly as described in "Indications". If
there is a problem, review the connection instructions and check the connections. If the problem is still not solved, see
"Troubleshooting" to find out what to do next.
• Pulse mode and hold-to-run mode
Hold-to-run mode means that the button has to be kept pressed to open or close – when the button is released, the motor
stops.
In pulse mode, pressing and releasing the button opens or closes the door automatically. Pulse mode can be configured for
either direction. Pulse mode must be active for automatic operation of the door.
Note that the applicable directive does not allow wireless transmitters to operate in hold-to-run mode – this is why all wireless
channels are disabled in hold-to-run mode.
Selecting pulse mode or hold-to-run mode
Select channel C033 and set the function you want.
Example 1: To set pulse mode for both opening and closing movements, set the value to 3.
Example 2: To set pulse mode for the opening movement and hold-to-run mode for the closing movement, set the value
to 1.
Hold-to-run if there is an error in the safety edge or PHOTO input
If the safety edge, photocell or vehicle loop is faulty, the automatic control unit automatically switches to hold-to-run mode
in the direction in which there is a fault. Even when the safety edge or photocell/vehicle loop are not working, you can still
open and close the door by keeping the button on the PCB pressed
• Checking safety functions
When the automatic control unit is taken into operation, all safety functions should be tested. Take the motor winders into
operation again by recoupling and checking the following functions:
• Check that the safety edges work as intended.
• Check that the load guard is activated under abnormal load.
• Check that the photocell (if there is one) is working.
• Check that the vehicle loop (if there is one) is working.
• If all the points above are OK, continue with commissioning. Otherwise return to the relevant section and check the
settings. If this does not help, see "Troubleshooting".
