If you wish to by-pass the interlock operation and allow the two doors to operate independently, you need to connect an ON / OFF switch in
parallel between terminals 16 (AUX1) and 19 (Common) of both operator control units.
This way when the switch contact is open the interlock is enabled, while when the switch contact is closed the interlock is disabled and the
two automatic doors can operate independently.
To enable interlocked operation you need to install the ET-DSEL digital programmer as program selector.
You cannot use the EV-MSEL mechanical key selector.
30) INTERLOCK SYSTEM
The interlock system is used to connect two automatic doors when a door can only open if the other is closed.
For the electrical connection between the ET-LOGIC-B control units of the two operators you need to use a UR24 module (optional) for each
control unit. Plug the UR24 module into the J2-OUT1 connector of the ET-LOGIC-B control unit.
30.1) ELECTRICAL CONNECTION FOR INTERLOCK
The above diagram shows the electrical connection between the two doors ensuring that they are interlocked during operation.
· Terminal 19 (COM) of control unit 1 must be connected to terminal C of its own UR24 module.
· Terminal NO of the UR24 module of control unit 1 must be connected to terminal 14 (STOP/I) of control unit 2.
· Terminal 19 (COM) of control unit 2 must be connected to terminal C of its own UR24 module.
· Terminal NO of the UR24 module of control unit 2 must be connected to terminal 14 (STOP/I) of control unit 1.
· Terminals 19 (COM) of both control units must be connected to each other.
· The Interlock input (Terminal 14) must be configured as N.C. (Function F24 = OFF)
The dotted line of the ON/OFF switch connected to the AUX/1 input is used to disable the interlock operation
(connection not essential for the system operation).
Switch OFF (contact open): interlock ON
Switch ON (contact closed): interlock OFF.
