4.7.6 Maintenance and checkout procedures
These procedures should be performed
every year
. A visual inspection, functional check-
out and safety analysis test has to be done. For the visual inspection follow paragraph
3.1. The functional checkout is done by proceeding a data transfer.
Note, the Quick Link has no electrical ground connection, so, the Safety Analysis Test
has to be performed by proceeding the Enclosure Leakage Current Test.
This test is performed to measure leakage current from chassis and exposed metal parts
to ground during normal conditions (N. C.) and single fault conditions (S.F.C.).
In any case, the leakage current has to be measured from front-and backpanel and the
metal shield of the Twisted Pair connector to ground.
Connect the unit under test to your Safety Tester.
With Quick Link, the position of the ground switch GND does not matter.
- During normal conditions (N.C.), referring to the electrical diagram, measurements
have to be done under the following conditions:
* Polarity switch
NORM and RVS
* S 1
closed
- During single fault conditions (S.F.C.), referring to the electrical diagram, the measure-
ments have to be done under the following conditions:
* Polarity switch
NORM and RVS
* S 1
open
Test has failed if the measured values are greater than:
N.C.
S.F.C.
