14.5 Option board with 2 serial outputs (24VDC power supply)
This option board does not require any programming. By default the time is
the local time dened in the Sigma, with 1.2-second impulses, and the line is
stopped.
Impulse generated from internal power (24V),
Connect the clock lines to the outputs A and B.
The current can be adjusted (from 50 to 100 mA) for each line, using the
potentiometer next to each terminal strip.
The (10 K) resistor on each output terminal strip is designed to prevent the
“line open” alarm message. It must be left if the line is not used.
Set the lines to “On” in the “Time outputs” technician menu (see page 36).
