Basler Electric BE1-50/51B-232 - Manual (Page 41)

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 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-232. 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)
 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).
