REX12-Tx-E electronic circuit protector
Enquire Enquiry of currently adjusted
adjusted current rating current independent of the operating
with REX12D-TE2-E mode (COM or standard), possible
for each channel directly on the
REX12D-TE2-E. Enquiry mode is started
by pushing the button between ≥ 2
seconds and < 5 seconds. After releasing
the button, the LED is RED for 333 ms to
indicate start of enquiry. Then the LED
flashes with a pulse/pause ratio of 1:2 at
a frequency of 1 Hz ORANGE to indicate
the set current value. After reaching
the set current rating, after repeated
indication of the RED LED for 333 ms the
signalling starts again. The enquiry mode
is quitted after 5 times of indication of
the set current rating or by pressing the
button and the display changes to current
operating mode. The enquiry mode is
available in all operating modes (ON, OFF,
LOW VOLTAGE and TRIPPED)
Settings for the The adjustment mode directly at the
current rating for REX12D-TE2-E is only available in the
REX12D-TE2-E standard mode. The adjustment mode is
started directly per channel by pushing
the button for ≥ 5 seconds. After releasing
the button, the LED is RED for 333 ms to
indicate the start of adjusting. The LED
flashes with a pulse/pause ratio of 1:4
at a frequency of 0.6 Hz GREEN. After
reaching the maximum adjustment value
the indication starts again. The overflow of
the maximum setting value after 1 ampere
is indicated by the RED LED lighting up
(333 ms). The adjustable current rating
is taken over by pressing the button
during the flashing of 1 ampere up to the
maximum adjustment value. If the button
is pressed, e.g. after the 7. flashing of the
GREEN LED, 7 ampere are taken over
for the current rating and the indication
changes to the current operating mode.
again. If the button is not pressed, the
adjustment mode will be left after the 5
times of signalling of the current rating
range, without taking over a new current
rating and the indication changes to the
current operating mode again.
The adjustment mode is available in
all operating modes (ON, OFF, LOW
VOLTAGE and TRIPPED).
