Power supply is applied to the sensor (brown and blue cables). The relay operates (connection between black and yellow cables) and remains ON until the sensor is activated. After activation of the sensor the relay releases (connection between black and grey cables.) VC11RT (See operation diagram). Power supply is applied to the sensor (brown and blue cables). When sensor is not activated, the relay operates (connection between black and yellow cables) and LED lights. When sensor is activated the VC12RT (See operation diagram). Power supply is applied to the sensor (brown and blue cables) and time measurement starts. When the set time has expired (010 min.) the relay operates (connection between black and yellow cable) and remains connected until the sensor is activated. After activation of the sensor the relay releases (connection between black and grey cable). As soon as the sensor is unactivated again the time measurements of the set time starts. Adjustment time measurement starts and LED flashes. After expiration of the set time (0-10 min.), the relay releases (connection between black and grey cables) and LED turns off. The relay remains released until sensor is activated again.
