CAUTION
When testing units with integrating reset characteristics selected, timing may be
affected by the integrating reset.
SECTION 5
TESTING
GENERAL
When not shipped as part of a control or switchgear panel, the relays are shipped in sturdy cartons to
prevent damage during transit. Immediately upon receipt of a relay, check the model and part number
against the requisition and packing list to see that they agree. Visually inspect the relay for damage that
may have occurred during shipment. If there is evidence of damage, immediately file a claim with the
carrier and notify the Regional Sales Office, or contact the Sales Representative at Basler Electric,
Highland, Illinois.
Proper operation of the relay may be confirmed by performing the operational test procedures in this
Section. In the event the relay is not to be installed immediately, store the relay in its original shipping
carton in a moisture and dust free environment.
DIELECTRIC TEST
In accordance with IEC 255-5 and IEEE C37.90-1989, one-minute dielectric (high potential) tests may be
performed as follows:
All circuits to ground: 2828 Vdc.
Input to output circuits: 2000 Vac or 2828 Vdc.
Output contacts are surge protected.
OPERATIONAL TEST PROCEDURE
The following procedure verifies operation of the relay. The test setup of Figures 5-1 and 5-2 are
intended primarily as an illustration of the principles involved. Other test setups known to be capable of
testing with the stated and implied tolerances (including equipment specifically designed for testing
relays) may be used.
Test Equipment Required
Current source with a range from 0 to 20 amperes ac (sensing input current).
Current source 0.2 to 3 amperes, ac (target operation).
Timer or counter.
