7
x
red: indicates DIP switch position 8 which switches between measuring and
configuration mode. Only when DIP switch position 8 is on/1, LTDR can be
configured; configuration mode is indicated by the LED blinking alternately green and
red.
When DIP switch position 8 is off/0, LTDR is in measuring mode; indicated by the
LED blinking green.
It is only possible to enter the configuration mode when DIP switch positions 1 to 7
are off/0 before setting DIP switch position 8 to on/1; otherwise the LED is blinking red
to indicate an error
x
blue: indicates the DIP positions through which groups of functions are selected, e.g.
all functions related to the analog current output or the switching output
