Testing of
high-set stage
Testing of the self-
supervision system
(IRF)
The switches of switchgroup SGR should be set
as follows:

Then the following signals are linked to the
output relays:
Output Function
(terminals)
A (65-66) Tripping of stage I>
B (68-69) (Tripping of stage I>>)
C (80-81) Signal on tripping of stage I>
(LED L3)
D (77-78) Start of stage I>> (LED L2)
E (71-72) Signal on internal relay fault
(LED L1)
The self-supervision system and its operation
indicator IRF and output relay E can be tested
in the Trip-Test mode described in section
The high-set stage is tested in the same way as
the low-set stage. The clock measuring the
operate time is stopped by contact 68-69 when
output relay B operates.
