10.4 Description of parameters
SIPART PS2 with and without HART communications
154 Operating Instructions, 09/2008, A5E00074631-08
41.YCUP - Value for "tight closing above"
This parameter is used to set the value for "Tight closing below" and "Tight closing above".
Note
The value in the "40.YCDO" parameter must always be less than that in "41.YCUP". The
tight closing function has a fixed hysteresis of 1%. The parameters "40.YCDO" and
"41.YCUP" are relative to the mechanical stops. Both parameters are independent of the
values set in the "7.SDIR" and "38.YDIR" parameters.
The factory setting is "99.5".
10.4.2.13 Description of parameters 42 and 43
42.BIN1 - Function binary input 1
and
43.BIN2 - Function binary input 2
These parameters determine the function of the binary inputs. The possible functions are
described below. The direction of action can be adapted to a normally closed or normally
open mode.
● BIN1 or BIN2 = On or -On
Binary messages from peripherals, e.g. from pressure or temperature switches, can be
read over the communication interface or fed through a logical OR combination with other
messages to trigger the fault message output.
● BIN1 = bLoc1
With this parameter value, you can lock the "configuration" operation mode against
reconfiguration. The lock is performed e.g. with a jumper between terminals 9 and 10.
● BIN1 = bLoc2
If binary input 1 is activated, then manual mode is also blocked in additional to the
configuration operation mode.
● BIN1 or BIN2 = uP or doWn Contact closes or -uP or -doWn Contact opens.
If the binary input is activated in automatic mode, the actuator regulates to the value
specified by the parameters "35.YA" and "36.YE".
● BIN1 or BIN2 Contact closes = StoP or -StoP Contact opens.
If the binary input is activated in automatic mode, the piezo valves are blocked. The
actuator remains at the last position. Leakage measurements can be performed in this
way without using the initialization function.
