Performing the testing
The system should be tested systematically, since correct
operation of the arc protection system guarantees personal
safety.
•
Activate each sensor separately and ensure at the central
unit that the light information travels through the entire
communication channel. Enter the test result of each sensor
under item 4 of Table 4.2-1, for example.
•
Once you have tested each sensor channel separately,
activate a few sensor channels’ together with current
criteria and verify tripping (preferably at least one trip per
I/O unit). Enter the activated channels under items 5 and 6
and the trip in column 7 in Table 4.2-1.
•
If light or current identifier information is transferred from
one central unit to another or between relays and the
central unit through the BI/O bus, ensure that this
information is transferred between the central units or
between the relays and the central unit. Enter the light or
current information ( L > or I > ) received by the central
unit under item 2 in Table 4.2-12.
•
Ensure the selectivity of the protection zones.
4.3.
Periodic commissioning
We recommend that VAMP 221 arc protection system
functionality shall be tested every five years or according to the
law.
