9.4 Description of parameters 
  SIPART PS2 with and without HART 
168  Operating Instructions, 10/2013, A5E00074631-11 
 
Description of parameters 40 and 41 
40.YCDO - Lower value for tight closing 
The factory setting is "0.5". 
and 
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 th
e 
values set in the "7.SDIR" and "38.YDIR" parameters.
 
The factory setting is "99.5". 
 
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".
