display description
SAFP Setting of a safety position that is approached when binary input is active.
Depending on the actuating element, the following options can be selected:
PRZV: Control ratio in [%] for proportional valves
mA: Control in [mA] for drives with current input as manipulated variable
V:
Control in [mA] for drives with voltage as manipulated variable
OPEN: Open valve completely
CLOS: Close valve completely
STOP Valve movement is stopped (e.g. if the valve has reached the limit stop).
The controller remains active and the binary input is automatically deactivated when the
limit stop is left. The following functions are available for selection:
OPEN: Opening movement is stopped
CLOS: Closing movement is stopped
These functions are only required when using valves without position feedback in con-
junction with limit switches.
If, for example, the set-point value has not yet been reached and the limit switch is
active, the opening or closing movement is stopped.
The STOP menu option is only displayed if, in the MODE menu, PCV, 2P – T or 3P – T
was selected as actuating element.
OPEN Valve is opened. The opening is restricted by the value set in VALV, MAX
(see chapter “12.17. VALV - Test function and setting of the control range”).
The OPEN menu option is only displayed if, in the MODE menu, SCV, 4 – 20 or 0 – 10
was selected as actuating element.
CLOS Valve is being closed. The closing is restricted by the value set in VALV, MIN
(see chapter “12.17. VALV - Test function and setting of the control range”).
The CLOS menu option is only displayed if, in the MODE menu, SCV, 4 – 20 or 0 – 10
was selected as actuating element.
HIGH Binary input active if 3 V < B_IN < 30 V
LOW Binary input active if 0 V < B_IN < 2.7 V

12.15. B_O1 - configuration of the binary output
In this menu, the binary output for one of the following functions can be configured:
NO
Binary output not active
PULS
Pulse output ( PULS)
Depending on a flow-rate, a pulse signal can be emitted.
LIMT
Output for limit value monitoring ( LIMT).
Depending on limit values, alarms or switching contacts can be set for the case that such values
are exceeded or not reached.
2_P
Output for discontinuous 2-state control ( 2_P).
