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 relays BE1-50/51B-219 (5 ampere model) and BE1-50/51B-
226 (1 ampere model). 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 Aac (sensing input current)
•
Current source 0.2 to 3 Aac (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).
