INSTRUCTION MANUAL FOR DAAB EP104 CONTROL BOARD
• Safety edge
Safety edge monitor
The integrated safety edge monitor in the automatic control unit performs a self test before the start of every movement. If
any of the safety edge devices is faulty, the EP104 is stopped and an error is indicated. Make sure that S.E1 is connected to
motor 1 and S.E2 is connected to motor 2.
The principle is that the automatic control unit measures the impedance over the safety edge device to ensure it matches
a specified value. The impedance changes if the safety edge device is activated, if there is a short circuit or if the circuit is
interrupted – the automatic control unit interprets all these events as an activated safety edge.
LEDs indicate an activated safety edge with a constant light. If an activated safety edge is deactivated, the LED starts
flashing and is extinguished the next time the door is operated.
!
The safety edge monitor only works correctly if the stop circuit and the limit switch are connected as described in this
instruction manual. See the sections "Low current" and "Signal reference".
Setting the impedance value for protection
You can set the impedance value for the safety edge circuit to between 1.0 and 9.9 kΩ in the following channels:
•
C115, impedance value for S.E1.
•
C125, impedance value for S.E2.
•
C135, impedance value for S.E3.
!
Note that the factory setting of S.E3 is disabled.
!
Note that if you enter the value 0.0, the safety edge input is disabled.
A safety edge can only be connected in series.
When safety edge devices are connected in series, one resistor is used in the outermost safety edge. The impedance value is
set in the relevant channel.
You can read the current values in the channels C114, C124, C134 and check them against the values in the corresponding
channels described above.
Safety edge function
The principal functions of the three safety edge inputs are:
•
S.E1 for the closing movement
•
S.E2 for the closing movement
•
S.E3 for the opening movement
!
Note that the factory setting of S.E3 is disabled.
Safety edge functions – general
These settings are the same for a safety edge for the closing movement and a safety edge for the opening movement.
•
Reversal/stop
A safety edge can be set to stop or reverse when it is activated.
S.E1 channel C112, S.E2 channel C122 and S.E3 channel C132.
1 = Reversal
2 = Stop
Option 1, Reversal, causes the unit to move to the fully open position after the delay configured in channel C493.
!
Option 2, Stop, stops the door without reversing. Use with care – the lack of the reversal function means people may
be trapped.
•
Reversal delay.
You can use channel C493 to set the time before reversal starts after the safety edge has been activated. The factory setting
is 0.10 seconds. You can configure a different delay between 0.03 and 2.00 seconds. The same channel is used for the load
guard and the safety edge.
Select channel C493 and set a suitable delay.
NOTE. Increasing the delay in C493 may increase the crushing forces.
Safety edge function in the closing movement
On delivery and after a reset, the EP104 is configured to reverse to the fully open position when the safety edge is activated
in the closing movement.
Safety edge function in the opening movement
On delivery and after a reset, the EP104 is configured to reverse when the safety edge is activated in the opening movement.
The settings for opening a safety edge are the same as for closing a safety edge.
Set the reversal function with the value 1 in channel C132, and specify the delay in channel C493.
