Congurationlevel
9.6 Binary input
The function of the binary input can be congured as required. Code c12 is used to deter-
mine the switching state for the active function. c12=NINV: the binary input is active when
the input terminals IN4+/IN4– are connected with each other. c12=INV: The binary in-
put is active when the connection between the input terminals IN4+/IN4– is interrupted.
Î Do not connect an external power supply to the input terminals.
− Inactive(c11=NONE): No function is assigned to the binary input.
− Priorityposition(c11=PRIO): The priority position is triggered and the actuator stem
moves to the position entered in Code c34 as soon as the binary input changes to the ac-
tive switching state. The valve leaves the priority position and follows the input signal af-
ter the binary input changes to the inactive switching state.
− Nextentryininformationlevel(c11=NEXT): If the NEXT function is selected in Code
c11, the rst code of the information level (i01) is displayed as soon as binary input
switching state is changed. After every new change to the active state, the next code of
the information level appears (i02, i03 etc.). The display switches back to the start screen
after all the codes of the information level have been displayed due to the binary input
switching or when the binary input's switching state remains unchanged for ve minutes.
− Backlight(c11=LAMP): When the binary input's switching state is active, the display
backlight is switched on permanently.
− Exitmanuallevelfortraveladjustment(c11=MEND): When the binary input's switch-
ing state is active, the actuator exits the manual mode. The actuator stem moves to the
valve position determined by the automatic mode.
