Auxiliary switches wiring
The “G” terminal block is connected to two auxiliary and independent
limit switches (SPDT free contacts), FCU1 and FCU2, which indicate
the position of the actuator to the final user. The terminal block “G” is
composed by two parts, one of which removable for easier wiring. To
simplify the procedure, it is possible to remove the removable part,
wiring it and insert it once the wiring is done.
Connect to the terminal block “G” between the following terminals:
•
“B” and “C” to obtain the signal of closing position.
•
“E” and “H” to obtain the signal of opening position.
The opening or closing signal comes when the blue cams push the
auxiliary electromechanical limit switch on the logic board. The cams
adjustment procedure is described on paragraph 6.6.
WARNING: during the installation it is recommended to verify the
alignment of the auxiliary limit switches by using a multimeter/tester.
The terminal block “R” is connected to a free contact NO which clos-
es in case of powered actuator and no detected anomaly. In case of
anomalies or not powered actuator the contact is open. The terminal
block “R” is composed by two parts, one of which removable for
easier wiring. To simplify the procedure, it is possible to remove the
removable part, wiring it and insert it once the wiring is done.

Potentiometer wirings (optional) (Fig.5)
The actuator with potentiometer includes an extra terminal
block “POT” (Fig.5) which grants the possibility to use the re-
sistive infomation concerning the actuator position. Wiring in-
struction presented at Paragraph 10.0. When the actuator
is at 45°, the resistance value of the potentiometer is 2.5KΩ

Heating resistors (Fig. 6)
All the actuators are equipped with “RIS” heating resistor which
works only if the actuator is connected to the power supply, when
the motor is not rotating and the temperature inside the actuator
goes down to 25°C / 77°F. It protects the actuator from the forma-
tion of condensation due to temperature changes.
The resistor is part of the electronics, it does not require additional
wiring and it is disabled when the internal temperature exceed 25°C
/ 77° F.
WARNING: to guarantee the normal operation of the resistor, it is
necessary to keep the actuator connected to the power supply
even in the open/close positions.
