    4. Operation and configuration 4.1. LED indicator functions The AQ-102LV unit has eleven (11) indication LEDs. Apart from the "Power" and "Error" LEDs, the user can write their own identifications for each of the remaining LEDs on the text insert located in the transparent pocket next to the LEDs.

    Unless the button is pressed, the latched trip relays remain active until the auxiliary power is disconnected. All LED indications also remain active even when the auxiliary power supply is disconnected unless the button is pressed.

    It is not recommended to cut or splice the cable on-site. However, if cutting or splicing is necessary due to the cable breaking, please contact your nearest Arcteq representative for instructions. The fixed light intensity threshold of an AQ-08 sensor is 8,000 lux. The sensor does not require further settings by the user.
