3.1 POWER WIRING
3.2 CONTROL INPUT WIRING
The PAXLC provides a number of control inputs, including Store, Reset,
Inhibit and Up/Down control. These inputs are active low (connected to
common), so the external switching device should be connected between the
control input and common terminals.
Up/Down - This input determines the direction of the count. Unconnected,
the meter will count up. When input is pulled low, the meter will count down.
Reset - When this input is pulled low, the meter will reset to zero. If the input
remains low or connected to common, the meter will be held in the reset mode,
and not able to count.
Inhibit - When low, this input will prevent the meter from counting. If the
input remains low or connected to the common, the meter will not be able to
count.
Store - A low will stop the display from updating. It will freeze the display
as long as the input is held low. Once released the display will update to the
current count display.
