9.4 Description of parameters
Factory setting:
168
• BIN1 or BIN2 =
contact uP or doWn closes, or
contact -uP or -doWn opens
If the binary input is activated, the actuator uses the value
defined by the "'35.YA' Start of manipulated variable limit /
'36.YE' End of manipulated variable limit (Page 164)"
parameter for controlling in "Automatic" mode.
• BIN1 or BIN2 contact closes = StoP or -StoP contact opens
In "Automatic" mode, the piezo valves are blocked when the
binary input is activated. The actuator remains at the last
position. Leakage measurements can be performed in this way
without using the initialization function.
• BIN1 or BIN2 = PSt or -PSt
Using binary inputs 1 or 2, a partial-stroke test can be triggered
by actuation of your choice of a normally closed or normally
open switch.
• BIN1 or BIN2 = OFF
No function
Special function of binary input 1: If binary input 1 is activated
in "P-manual mode" by means of a jumper between terminals 9
and 10, the firmware version will be displayed when the mode
button is pressed.
If one of the above functions is activated simultaneously with the
"BIN1" and "BIN2" parameters, then: "Blocking" takes priority over
"uP". "uP" takes priority over "doWn". "doWn" takes priority over
"PST".
