9252000991 Rev N BE1-50/51B Testing 5-1
SECTION 5 • TESTING
GENERAL
Dielectric testing, operational testing, and periodic testing are described in the following paragraphs.
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: 2,828 Vdc.
Input to output circuits: 2,000 Vac or 2,828 Vdc.
Output contacts are surge protected.
OPERATIONAL TEST PROCEDURE
The following procedures verify operation of BE1-50/51B relays. The test setups 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 Aac (sensing input current)
• Current source 0.2 to 3 Aac (target operation)
• Timer or counter
CAUTION
When testing units with integrating reset characteristics selected, timing may be
affected by the integrating reset.
