.

NOTE
If the control function to close tightly is activated, for parameter

“49. LIM” the monitoring of the control deviation in each overrun direc-

tion (YCDO: < 0 %, YCUP: > 100 %) is disabled. This function is par-

ticularly useful for valves with a soft seating. For long term monitoring

of the end-stop positions, we recommend activating the parameters

“52. ZERO” and “53. OPEN”.

Value for tight closing, bottom

and

Value for tight closing, top

.

NOTE
“40.YCDO” must always be set to less than “41.YCUP”. The tight

closing function has a fixed hysteresis of 1 %. “40.YCDO” and

“41.YCUP” relate to mechanical stops and are independent of the

settings of “7.SDIR” and “38.YDIR”.

Function digital input 1 (see figure 4-6, page 96)

and

Function digital input 2 (see figure 4-6)
The parameters “BIN1” and “BIN2” can be set individually depending

on the purpose. The direction of action can be adapted to an NCC or

an NOC.

S

BIN1 or BIN2 = on or --on
Digital messages of the periphery (e.g. pressure or temperature

switches) can be read out via the HART interface or lead to re-

sponding of the fault message output by OR linking with other mes-

sages.

S

BIN1 = bLoc1
The Configuration operating mode is locked to prevent it being ad-

justed (e.g. by a wire jumper between terminals 9 and 10).

S

BIN1 = bLoc2
If digital input 1 has been activated, manual operation is also locked

in addition to the Configuration operating mode.

S

BIN1 or BIN2 = uP or doWn (contact closes) or --uP or --doWn (con-

tact opens).
The actuator drives the linear actuator to the upper or lower stop

when the digital input is activated with continuous contact.

S

BIN1 or BIN2 (contact closes) = StoP or --StoP (contact opens).
