Pwr (SW9)
This switch performs a properly supervised system shutdown when placed
in the OFF position. SW9 generates a power fail interrupt to the CPU and
after a 10-ms delay, shuts the power off to the entire system board.
Figure 3.3— Switches SW9 and SW8, and potentiometers P3 and P2 (upper left corner of main board)
Placing SW9 in the ON position causes a “power on” restart. A “power on”
restart interrupts the flow calculations but does not affect the configuration
or historical flow data if the NVRAM lithium backup battery (CN20) is
enabled. Power-on restarts are logged in the event log. The display will
show:
Power on Restart
Display Wakeup (SW8)
If the display is configured to timeout and turn off, pressing the SW8
button will turn on the display. See Figure 3.3.
Contrast (P3)
The LCD display contrast is adjusted by turning the screw. See Figure 3.3.
Bklight (P2)
This potentiometer adjusts the brightness of a backlit display (available
only on configurations with backlit display). See Figure 3.3.
LCD PwrSav (CN21)
When a backlit display is configured to timeout and turn off, and the CN21
jumper is in the ON position, the display will turn off completely. When
the CN21 jumper is in the OFF position, the backlighting will turn off,
leaving the display on in a standard or non-backlit mode. See Figure 3.4.
