8.1
Feedback signals via output contacts (binary)
The output contacts can be used to indicate operation modes of the actuator or the
controls as binary signals. The signals can be freely assigned. Example:
Output contact open = no thermal fault
Output contact closed = thermal fault in actuator
The output contacts are denominated in the wiring diagram as follows:
●
Output contacts 1 to 5: DOUT1 to DOUT5
●
Alarm contacts: NC fault/NO ready
Signal assignment is made via the parameters:
OUTPUT CONTACT 1
to
OUTPUT
CONTACT 5
and
ALARM CONTACT
.
Alarm contact default value:
FAULT GROUP 3
= fault signal (includes: torque fault, thermal fault, phase failure
and internal faults)
Default values
OUTPUT CONTACT 1
to
OUTPUT CONTACT 5
:
OUTPUT CONTACT 1 = CLOSED POSITION
OUTPUT CONTACT 2 = OPEN POSITION
OUTPUT CONTACT 3 = REMOTE SW. POSITION
OUTPUT CONTACT 4 = TORQUE FAULT (CLOSE)
OUTPUT CONTACT 5 = TORQUE FAULT (OPEN)
8.2
Feedback signals (analogue)
Valve position
Signal: E2 = 0/4 – 20 mA (galvanically isolated)
Designation in the wiring diagram:
ANOUT1 (position)
Torque feedback
Signal: E6 = 0/4 – 20 mA (galvanically isolated)
Designation in the wiring diagram:
ANOUT2 (torque)
