End Point Auxiliary Switches (with accessory DMVE)
End point switches change over when the valve is fully open or
closed. They are free contacts with 24V AC/DC, 4A max voltage on
terminals. End point switches can be utilized to indicate valve stroke
end positions and for relay control of additional plant equipment.
When the actuators are controlled individually or in sequence, it is
possible to use the end switches to toggle when the valve is fully
open or fully closed. The auxiliary switch position according to con
-
trol signal (Y) is shown in the picture below.

Diagnostic
The actuator is provided with a self diagnostic algorithm able to de
-
tect faulty conditions:
•
stroke calibration out of range 5-60mm;
•
unexpected stall condition (e.g. valve stuck or extra stroke due
to actuator link loose);
•
voltage supply out of range.
These faulty conditions are signalled through the GREEN and RED LED
on the electronic board blinking accordingly (see Diagnostic – Alarm
Function Table).
IP65
Protection against water and solid object IP65 is guaranteed by in
-
ternal seals, IP65 cable gland and the proper engineering of the en
-
closure.
One IP65 PG13,5 cable gland and one IP65 PG13,5 plug are supplied
with the actuator.

*To guarantee “Nema Type 2” protection:
•
use flexible metal conduit (not supplied);
•
Push the listed conduit fitting device over the actuator’s cable
to butt against the enclosure. Screw in conduit connector. Jack
-
et the actuators input wiring with listed flexible conduit. Properly
terminate the conduit in a suitable junction box.
