Procedure 5.
Setting the Three Ultima Gas Monitor Alarm
Setpoint Values
The Ultima Gas Monitor has three alarm levels. The relay module can
be connected directly to the Ultima Gas Monitor to provide three levels
of relays and a normally-energized trouble relay. The three levels of
alarm also appear on the Ultima Gas Monitor LCD display even if an
Ultima Gas Monitor relay module is not used.
• Alarm #1 must be set at a lower or equal value than Alarm #2
• Alarm #2 must be set lower or equal than Alarm #3
• On the oxygen unit:
• Alarms #1 and #2 are negative or downward acting
• Alarm #3 is positive or upward acting
• Alarms #1, #2 and #3 can be set to any value; they are
independent of one another.
To set the three levels of alarm:
1. Press the SEND button.
• The display prompts: SEND?
2. Press the ALARM button.
• The display prompts: 0=SetPt 1=OnOff
3. To set the alarm values, press the 0 button.
• The display prompts: Alm Gas Type +.
4. Press the + or - button to scroll through the available list:
NOTE: If your gas type or range is not shown on the Controller
display, use the custom range option on the menu.
5. When the selection matching your sensor type is found, press the
ENTER button. (Invalid entries are ignored.)
• The display prompts: Alm Set Point #.
6. Using the NUMBER buttons, enter the desired alarm setpoint 1, 2
or 3; then, press the ENTER button. (Invalid entries are ignored.)
• The display prompts: SetPVal ###
NOTE: If the custom range option was selected, a decimal point
may be implied, since this range can be used for decimal
point and non-decimal point Ultima units. When sending a
value to an Ultima unit that indicates a decimal point, enter
the data assuming an implied decimal point
(e.g., "009" is interpreted as "00.9").
