To proceed to the next position press the PRO-
GRAM push button for about 1 second until
the indicator of the second setting starts flash-

Press the push buttons PROGRAM and STEP
simultaneously to activate tripping of stage 1
(e.g. the I> stage of the overcurrent module
SPCJ 4D29). The output relays will operate
according to the actual programming of the
relay switchgroups SGR. If the main trip relay
is operated the trip indicator of the measuring
module is lit.
h)
The starting and tripping of the remaining
stages are activated in the same way as the first
stage above. The indicator of the corresponding
setting starts flashing to indicate that the con-
cerned stage can be activated by pressing the
STEP and PROGRAM buttons simultaneously.
For any forced stage operation, the output
relays will respond according to the setting of
the relay output switchgroups SGR. Any time
a certain stage is selected that is not wanted to
operate, pressing the PROGRAM button once
more will pass by this position and move to the
next one without carrying out any operation of
the selected stage.
It is possible to leave the trip test mode at any
step of the sequence scheme by pressing the
PROGRAM push button for about five seconds
until the three digits to the right stop flashing.
