This test checks all outputs of the relay. It is a convenient way to determine proper system connections and
verify the operation of all relay contacts, without having to apply currents and voltages to simulate faults. Pro-
tection can be enabled or disabled, as deemed necessary.
If this test is run remotely through ALPS-Link, then switch RM BRKR must be in the down
position to allow the outputs to operate. Refer to Section 8.4.1: HARDWARE SWITCHES for
details on changing the switch position. Note that the relay is shipped from the factory with
NOTE
the switch in the down position allowing the outputs to operate.
