INSTRUCTION MANUAL FOR DAAB EP104 CONTROL BOARD
• Connecting a safety edge
The safety edge resistor must be installed in the safety edge device so that a break in the resistor or the cable is interpreted as
actuation of the device. See the wiring diagram below.
The resistor can be between 1.0-8.2 kΩ with 1% tolerance and a power capability of at least ½ W. FAAC Nordic AB recommends
an impedance of 8.2 kΩ. A safety edge can only be connected in series.
When connecting in series, only one resistor is used in the outermost safety edge as shown in the wiring diagram below. The
maximum number of safety edge devices connected in series with an impedance of 8.2 kΩ is six per input.
Note that the impedance used for a safety edge must be checked and entered into the EP104 during commissioning, see
"Commissioning" below.
!
Other types of impedance safety edge must not be connected directly to the safety edge inputs – they require an external
control unit.
See the instruction manual for the device used.
Only use safety edge devices approved by FAAC Nordic AB.
