EB 8484-1 EN 16-3
Annex A (configuration instructions)
Code Reading/values Description
P10 Control response
[PID]/PD
The integral action in the control parameters can be deactivated.
P11 Pressure limitation
ON/[OFF]
The signal pressure can take on the same pressure as the supply air
at the maximum [ OFF ] or, in the case that the maximum actuator
force can damage the valve, the pressure is limited to approx.
2.4 bar [ON].
P12 Set point cutoff
decrease (end position
w <)
[ON]/OFF
Lower tight-closing function:
If w reaches up to 1 % towards the final value that causes the
valve to close, the actuator is immediately completely vented (with
ATO : air to open) or filled with air (with ATC : air to close).
P13 Set point cutoff increase
(end position w >)
ON/[OFF]
Upper tight-closing function:
If w reaches up to 99 % towards the final value that causes the
valve to open, the actuator is immediately completely filled with air
(with ATO : air to open) or vented (with ATC : air to close).
P14 Switching mode of soft -
ware limit contact
[NO.NO]
Switching mode of software limit contact 1 (SLS1) and 2 (SLS2)
when activated (when the positioner has been initialized).
− Explosion-protected version according to EN 60947-5-6:
NO.NC : SLS1 Conductive SLS2 Non-conducting
NO.NO : SLS1 Conductive SLS2 Conductive
NC.NC : SLS1 Non-conducting SLS2 Non-conducting
NC.NO : SLS1 Non-conducting SLS2 Conductive
− Version without explosion protection:
NO.NC : SLS1 Conductive SLS2 Non-conducting
NO.NO : SLS1 Conductive SLS2 Conductive
NC.NC : SLS1 Non-conducting SLS2 Non-conducting
NC.NO : SLS1 Non-conducting SLS2 Conductive
When the positioner has not been initialized, the signal states of
the software limit contacts are the same as in the state of no re-
sponse.
If there is no mA signal at the terminals 11/12, both software limit
contacts switch to the non-conducting state.
P15 Switching threshold of
software limit contact 1
–20 to 120 % [2 %]
Software limit 1 is displayed or can be changed in relation to the
operating range (steps of 0.5 %).
The contact switches to the responded state (Code P14 ) when the
value falls below the limit.
