2 WIRES
(see the remote connections diagram) With the “2 wires” option 2 different
activities may be selected:
In “2 wires, signal ON to open”, the actuator opens if the signal switches to ON and closes if
the signal goes to OFF. In “2 wires, signal ON to close”, the actuator closes if the signal
switches to ON and opens if the signal switches to OFF.
The circuits associated to the inputs can be supplied by the internally generated 24 V DC or
by an external 20-125 V DC or 20-120 V AC (50/60 Hz).
The signal levels are the following:
•
Minimum ON signal > 20 V DC or 20 V AC (50/60 Hz)
•
Maximum ON signal < 125 V DC or 120 V AC (50/60 Hz)
•
Maximum OFF signal < 3 V DC or V AC
•
Minimum signal duration > 300 ms
•
Total current drawn from remote controls < 25 mA
5.7.2
Output Contacts
•
Monitor relay: on the terminal board, the voltage-free, change-over contacts of
the monitor relay are available. The monitor relay indicates that the actuator can
be remotely controlled or that there is a problem or condition which prevents
remote control of the valve. The conditions that cause the relay to switch over are
listed in Section 9.1.6, Output relays.
•
AS1, 2, 3, 4 relays: on the terminal board, the voltage-free contacts of 4 latching
relays are available. The status (make or break) and the conditions that cause
the switching of the relay can be viewed and configured by using the “VIEW and
SET-UP” features. The status of the latching relays is immediately updated as the
associated conditions for change occur. Moreover, the status of the above contacts
is cyclically updated (every 500 ms).
