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.
BIN1 or BIN2 = on or --on
S
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.
BIN1 = bLoc1
S
The Configuration operating mode is locked to prevent it being ad-
justed (e.g. by a wire jumper between terminals 9 and 10).
BIN1 = bLoc2
S
If digital input 1 has been activated, manual operation is also locked
in addition to the Configuration operating mode.
BIN1 or BIN2 = uP or doWn (contact closes) or --uP or --doWn (con-
S
tact opens).
The actuator drives the linear actuator to the upper or lower stop
when the digital input is activated with continuous contact.
BIN1 or BIN2 (contact closes) = StoP or --StoP (contact opens).
