5.2. Arc light and pressure point sensor AQ-02
AQ-02 is an arc light and pressure point sensor that comes with arc light detection and ambient
pressure detection. The AQ-02 sensors should be mounted in the switchgear cubicles in such a way
that the light-sensitive part covers the protected area as completely as possible. Only one sensor
should be used per one closed metal-clad compartment. The AQ-02 sensors c
canno
annott be installed in
open spaces.
The default light intensity threshold for an AQ-02 sensor is 8,000 lux. Depending on the demand of the
application, the default threshold can also be set to 25,000 lux or 50,000 lux. An arc light sensor does
not require further settings by the user. Its detection radius is 180 degrees. The pressure threshold is
fixed at 0.2 bar above ambient pressure.
Figure. 5.2. - 10. AQ-02 arc light and pressure point sensor.
An AQ-02 can only be installed on the compartment wall as not to block pressure detection located
next to "the eye". The unit placed on the wall (with the gray side against the wall), and then fixed to the
wall with two screws. No external mounting plates are needed regardless of the mounting type;
however, mounting brackets can be used if so desired.
Up to three (3) sensors can be connected in series. Installing a connection cable is simple as each end
of the sensor has a detachable cover over the cable connectors. Please remember to reattach the
cover once the wires have been installed.
5.3. Arc light fiber optic loop sensor AQ-06
AQ-06 is an arc light fiber optic loop sensor, which is a plastic fiber optic cable. Fiber sensors are
distributed through the protected switchgear cells. The fixed light intensity threshold of an AQ-06
sensor is 8,000 lux. The sensor does not require further settings by the user. The sensor's detection
radius is 360 degrees.
AQ-06 sensors can be ordered in pre-manufactured lengths of 3…40 meters (3 m, 5 m, 10 m, 15 m,
20 m, 25 m, 30 m, 35 m, 40 m). 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.
When requested, the ends of an AQ-06 cable can be covered with black rubber to avoid light detection
outside the protected zone (see the figure below). The covered area can be as large or small as
necessary. For more information, please consult your nearest Arcteq representative.
