ABB ARC GUARD SYSTEM™ – T VOC-2 INSTALL ATION AND MAINTENANCE GUIDE
INFORMATION
After completed Start-Up Sequence at the first
time installation the complete sytem needs
checking.
This includes checking that the detectors and
HMI works as intended.
See: "4.3.1 Start-Up Sequence" on page 33.
4.3.2 Controlling
INFORMATION
Do the test after installation and before the Arc
Monitor is used!
This test is done for each installed detector
and the Arc Monitor.The test will check that
the detectors react to a simulated arc and the
HMI will display a notification window showing
which detector and which circuit breaker is
tripped. The breaker that is connected to the
Arc Monitor should trip. Use a camera flash to
simulate an arc. At normally sensitivity the Arc
Monitor will react to the flash.
INFORMATION
Flash specifications to simulate an arc, 16 (m)
guide no. 21 DIN/100 ASA.
Testing the installation
Repeat the following steps to check all installed detectors
separately:
1. Simulate an arc by using a camera flash. Mobile
phone flash shall not be used.
2. Set the camera flash to approximately 0.5 ms.
3. Place the camera flash at a distance between 1.5 -2
meters (60-80 inches) from the detector.
4. Make sure no object is standing in the way.
5. Point the camera flash towards the detector.
6. Press the flash test button. Minimum interval
between flashes is 15s.
Do the following steps to check the Arc Monitor:
1. Check the HMI display.
2. If the detector reacts correctly and causes a
trip then it should show on the HMI display as a
notification window.
3. The notification window shows, Trip has Occurred,
which detector, which trip contact, at what time
and date.
4. The breaker that is connected to the Arc Monitor
should trip, depending on the configuration.
5. At the notification window, If manual reset is
configured, press Reset. If auto reset is configured,
press Menu.
