Programming the High & Low Alarm Pressure Set Points
After placing the board in the program mode and touching the
High function icon, the high line pressure set point and programming
keypad is displayed. The currently programmed high pressure alarm
set point is displayed in the white box
in the top left corner. If the gas module
being programmed is a typical 50 psig
delivery pressure gas, the board has
been pre-programmed at the factory
with the high line pressure set point at
60 psig, so the display should show the
number 60. If you wish to change this
setting, simply
• type in the new pressure
• touch Enter,
• on the next screen touch Back
• on the next screen touch Save to adjust the pressure setting.
After placing the board in the program
mode and touching the Low function
icon, the low line pressure set point and
programming keypad is displayed. The
currently programmed low pressure
alarm set point is displayed in the white
box in the top left corner. If the gas
module being programmed is a typical
50 psig delivery pressure gas, the board
has been pre-programmed at the factory
with the low line pressure set point at
40 psig, so the display should show the
number 40. If you wish to change this
setting, simply
• type in the new pressure
• touch Enter
• on the next screen touch Back
• on the next screen touch Save to adjust the pressure setting.
NOTE:
The alarm is designed with a safety feature so that the high
and low set points must be at least 1 (psig / in Hg), 1 (bar) or 1
(kPa) increments apart. The high set point will not be able to be set
below the low set point and vice versa.
