If voltage is applied simultaneously to terminals 2 and 3, terminal 2 is the leading one and the actuator moves to the OPEN position.
note!
Make certain in 3-point mode that the pulse duration of a controller lasts for at least 1 second. A pause time of at least 500 ms is required
before controller activation is repeated. Observe the duty cycle specified on the type label.
Please note the circuit board must remain power supplied to allow heating resistances working.
