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 or 2,000 Vac
Input to output circuits:
2,828 Vdc or 2,000 Vac
Output contacts are surge protected.
OPERATIONAL TEST PROCEDURE
The following procedures verify operation of relays BE1-50/51B-214/-215/-223 (5 ampere model) and
BE1-50/51B-225 (1 ampere model). The test setup of Figures 5-1 and 5-2 (BE1-50/51B-214/-225) are
intended primarily as an illustration of the principles involved. The BE1-50/51B-215 is illustrated in Figures
5-3 and 5-4. The BE1-50/51B-223 is illustrated in Figures 5-5 and 5-6. 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)
•
AC or DC voltage source (target operation)
•
Timer or counter
CAUTION
To ensure proper timing during testing, before each test, remove the current from
the unit for R times D seconds (refer to Section 1,
Specifications, Time Reset
for
R and D definitions).
