OPERATIONAL TEST PROCEDURE
The following procedure verifies operation of the relay. The test setup of Figure 5-2 is intended primarily
as an illustration of the principles involved. Other test setups known to be capable of testing within the
stated and implied tolerances (including equipment specifically designed for testing relays) may be used.
Preliminary Settings
(a) All contact-sensing inputs are open circuited.
(b) All Condition Switches and Mode Switches are UP.
(c) Some styles of relay are equipped with multiturn pots accessible through holes in the front panel.
All such controls should be turned fully CCW (to their minimum settings) except the ∆V control,
which is turned fully CW.
(d) Adjust bus and line sensing input voltages to 95 Vac with zero phase difference.
(e) Apply power to the relay.
(f) If equipped with power supply status output (option 3-6), verify that the power supply status
output contacts are open.
(g) Remove input power and verify that the status contacts close.
(h) Apply power to the relay.
