INSTRUCTION MANUAL DAAB AUTOMATIC CONTROL UNIT EP105
28
Revision 3
• Input for photocell
Terminal 29 can be used for photocell or vehicle loop via a control unit. The photocell can advantageously receive power
from terminals 28 and 30, see Signal list section. The indication for this input is marked PHOTO, see section on Indications.
If two units are to be used at the same time on this input, these must be connected in series via potential-free contacts with
normally closed function.
Input for photocell in 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 a vehicle opening the door to fully open in this way, the door can instead stop, to prevent passage.
To then close after an automatic closing time, C340 is set to 2 and C500 to a suitable delay.
Input for photocell in 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.
Programmable input 6 configured for photocell
There is also an option for an extra input for photocell or vehicle loop by using terminal 27, and changing P600 to 2. Set
the desired safety function in P640, P641, P642 and P643. The indication for this input is marked INP6, see section on
Indications.
• Limited running time
If the limit switches have been selected in L001 or L002, a channel is displayed for limited running time, L203. Limited
running time is used to protect the equipment against possible damage when the door or gate does not reach the open or
closed position because of some fault. Limited running should be set to a slightly longer time than the normal running time
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 L211 for motor 1 and L221 for motor 2. Select channel L203 and enter a value about 3 seconds longer
than the longest time measured. If too short a time has been specified in L203, the error code E003 is displayed when the time
in L203 has passed and the control unit stops the movement.
When encoder has been selected in both L001 and L002, L203 is not displayed as it does not need to be set either.
• 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.
