Device description The switching actuator is part of the Gira door communication system. Switching functions operated via the 2-wire bus are executed via the potential- free relay contact of the switching actua- tor.
Operating elements and indicators "Progr." button The "Progr." button has two functions: 1. Starting programming mode of the switching actuator: If the "Progr." but- ton is pressed for 3 seconds while the system is in programming mode, the programming mode of the switching actuator is started.

"Funktion" button The required operating mode can be set with the "Funktion" button (see Page 9). The next operating mode is selected with each button press. The LEDs next to the operating mode names indicate the active operating move. LED indication The LEDs only illuminate while the door communication system is in program- ming mode.
The switching actuator is connected to the 2-wire bus via these terminals. Polar- ity need not be taken into account here, as the polarity of the Gira door communi- cation system 2-wire bus is neutral. Binary in One or more mechanical buttons (NO...
Mounting Attention Installation and mounting of electrical devices may only be carried out by a qualified electrician. For installation protected from dripping and sprayed water, mount the control unit to a top-hat rail in the distribution. The device connection and bus connec- tion are made via terminal screws.
Setting operating mode The switching actuator can be used in five different operating modes: • Schalten (Switching, see Page 12) • Timer/sek. (Timer/sec., see Page 14) • Timer/min. (Timer/min., see Page 16) • Impuls (Pulse, see Page 18) • Türöffner (Door opener, see Page 20) Proceed as follows to select the desired operating mode: 1.
Switching operating mode after programming If the operating mode of a previously pro- grammed switching actuator was switched, the programming remains in tact. When only switching between switching functions, e.g. from "Schalten" to "Timer/ min.", the switching function with the modified conditions is executed.
Information on programming Automatic assignment of the switching actuator The switching actuator is automatically assigned to the button of the home stations. If the switching actuator is pro- grammed to a specific button, the auto- matic assignment is lost. • Switching actuator functions must be assigned in a separate programming procedure, i.e.
"Schalten" (Switching) operating mode In the "Schalten" operating mode, the device is activated via the press of a but- ton and remains activated until the button is pressed again. The "Schalten" operating mode can be assigned to the following buttons: •...
Page 13
Programming "Schalten" 1. Start programming mode at the control unit by pressing the "System- progr." button for 3 seconds until the LED next to the button starts flashing. ✓ The LED of the last set operating mode flashes at the switching actuator. 2.
"Timer/sek." operating mode The "Timer/sek." operating mode (1 - 10 s) could be used for direct operation of the door opener of a back/side door, for example. It can then be operated directly, even if no calls were initiated from the back/side door.

Programming "Timer/sek." 1. Start programming mode at the control unit by pressing the "System- progr." button for 3 seconds until the LED next to the button starts flashing. ✓ The LED of the last set operating mode flashes at the switching actuator. 2.
"Timer/min." operating mode The "Timer/min." (1 - 10 minutes) operat- ing mode could be used for the operation of path illumination or staircase illumina- tion (without security function), for exam- ple. After the button is pressed, the contact closes according to the set time. The acti- vation time can be set within the range of 1 to 10 seconds via the adjuster.

Programming "Impuls" 1. Start programming mode at the control unit by pressing the "System- progr." button for 3 seconds until the LED next to the button starts flashing. ✓ The LED of the last set operating mode flashes at the switching actuator. 2.
"Türöffner" (Door opener) operating mode In the "Türöffner" (1 - 10 seconds) operat- ing mode, the switching actuator of the button of the home station is oper- ated. The activation time of the door opener can be set within the range 1 to 10 seconds via the adjuster.
