10.2 Description of parameters
SIPART PS2 with PROFIBUS communication
Operating Instructions, 09/2007, A5E00127926-07
151
If the binary input is activated, the actuator uses the value defined by "YA" and "YE" for
controlling in the "Automatic" mode.
●
BIN1 or BIN2 (contact closed) = StoP or -StoP (contact open).
In "Automatic" operating mode the piezo valves are blocked when the binary input is
activated. The actuator remains in the last position. Leakage measurements can then be
taken without the initialization function.
●
BIN1 or BIN2 = PSt or -PSt
Binary inputs 1 or 2 can be used to initiate a partial stroke test by pressing either a
normally closed or a normally open contact depending on the choice.
●
BIN1 or BIN2 = OFF (factory setting)
No function
The following is applicable if one of the aforementioned functions has been activated
simultaneously using the "BIN1" and "BIN2" parameters: "Blocking" has priority over "uP"
and "uP" has priority over "doWn".
The factory setting is "OFF".
