3 WIRES (see the remote connections diagram shown below)
With option "3 wires" (OPEN, CLOSE, COMMON), the actuator can be driven in either
"push-to-run” or “latched with instant reverse” mode.
In “ push-to-run ” mode, the actuator can be driven to the desired position by switching the
OPEN or CLOSE signal to ON. As the signal returns to OFF, the motor is de-energised.
In “latched with instant reverse” mode, when the OPEN or CLOSE signal switches to ON,
the motor is energised, and it runs on after the signal returns to OFF. If the signal relevant to
the opposite direction goes ON, the actuator reverses its direction and maintains the new
direction also if the signal returns to OFF.
2 WIRES (see the remote connections diagram shown below)
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. This option requires two wires
(signal and common).
The circuits associated to the inputs are opto-coupled and be supplied by the internally-
generated 24VDC or by an external 20-125VDC or 20-120VAC (50/60Hz).
The signal levels are the following:
• Minimum ON signal > 20 VDC or 20 VAC (50/60Hz)
• Maximum ON signal < 125 VDC or 120 VAC (50/60Hz)
• Maximum OFF signal < 3V
• Minimum signal duration > 500 ms.
• Total current drawn from remote controls < 25mA
