• You have a SIPART PS2 in version "2-, 3-, 4-wire".
• Positioner is connected in accordance with the connection
graphics for 2/3/4-wire systems shown in section "Electrical
wiring (Page 81)".
• 0 MA
• 4 MA
This parameter is used to set the current range of the setpoint.
The selection of the current range depends on the type of connec-
tion. The "0 MA" setting (0 to 20 mA) is only possible for three-wire
and four-wire connections.
4 MA
• riSE
• FALL
This parameter is used to set the setpoint direction. The setpoint
direction is used to reverse the direction of action of the setpoint.
• Rising (riSE): A higher value at the setpoint input results in
opening of the valve.
• Falling (FALL): A higher value at the setpoint input results in
closing of the valve.
The setpoint direction is primarily used for the split-range mode
and for single-acting actuators with the safety setting 'uP'.
