There follows a list of tests which can be used to check that the unit is fully operational. For a more limited test for
the reception of units we recommend carrying out only the tests listed in sections: 6.2, 6.5, 6.6, 6.7 and 6.9.
6.1. CONNECTIONS AND NECESSARY EQUIPMENT
Necessary equipment:
•
Up to 5 AC voltage power supplies
•
One DC voltage power supply
•
One chronometer
•
One multimeter
Connect the relay as indicated in the external connections diagram, Figure 3 (189C4129F1).
Depending on each test, VAC power supplies shall be connected according to the wiring diagram.
For safety reasons, the relay shall be grounded.
Apply power always through terminals A10 and B10 at the rated voltage indicated on the front plate.
For simulating the external contacts closing (inputs to MOV unit) we will use jumpers and switches.
6.2. VISUAL INSPECTION
Check that the relay has not suffered any kind of damage due to transportation and handling.
Check that all the screws are sufficiently tight and that the terminal strips have not been damaged in any way.
Check that the information on the characteristics plate coincide with those of the ordered model.
6.3. INSULATION TESTS
• Progressively apply 2000 RMS volts between each group of terminals indicated below and the case during one
second.
• The independent relay groups are as follows:
Group 1:
Group 2:
Group 3:
Group 4:
Group 5:
Group 6:
Group 7:
Group 8:
Group 9:
GEK-106271
DURING ALL TESTS, TERMINALS A9 AND B9 SHALL BE
A10, B10
A1 to A6, B1 to B4
C9 to C12, D9 to D12
C9, C10, D9, D10
A11, B11
A12, B12
C1, D1
C2, D2
C4, D4
