The programming menu has a programming status listing that allows the operator to view the gas, range, and soft-
ware version number of the program, as well as the current alarm settings, target and calibration gas settings, cali-
bration gas level setting, RS-485 ID number, and estimated remaining sensor life. The programming menu also
allows the changing of target gas and calibration gas settings (see section 3.7), the calibration gas level setting (see
section 3.82), and alarm levels (see section 3.10).
The following procedure is used to view the programming status of the sensor:
a) First, enter the programming menu by holding the programming magnet stationary over “PGM 2” for 30 sec-
onds until the display reads “VIEW PROG STATUS”, then withdraw the magnet. At this point you can
scroll through the programming menu by momentarily waving the programming magnet over “PGM 1” or
“PGM 2”. The menu options are: View Program Status, Set Alarm 1 Level, Set Alarm 2 Level, Set Gas Factor,
Set Cal Factor, and Set Cal Level.
b) Next, scroll to the “VIEW PROG STATUS” listing and then hold the programming magnet over “PGM 1”
for 3 seconds. The menu will then automatically scroll, at f ive second intervals, through the following informa-
tion before returning back to the “VIEW PROG STATUS” listing.
1 - The gas type, range of detection and software version number. The menu item appears as: “LEL 0-100 V6.0”
2 - The alarm set point level of alarm 1. The menu item appears as: “ALM1 SET @ 20%”
3 - The alarm f iring direction of alarm 1. The menu item appears as: “ALM1 ASCENDING”
4 - The alarm relay latch mode of alarm 1. The menu item appears as: “ALM1 NONLATCHING”
5 - The alarm relay energize state of alarm 1. The menu item appears as: “ALM1 DE-ENERGIZED”
6 - The alarm set point level of alarm 2. The menu item appears as: “ALM2 SET @ 40%”
7 - The alarm f iring direction of alarm 2. The menu item appears as: “ALM2 ASCENDING”
8 - The alarm relay latch mode of alarm 2. The menu item appears as: “ALM2 LATCHING”
9 - The alarm relay energize state of alarm 2. The menu item appears as: “ALM2 DE-ENERGIZED”
10 - The alarm relay latch mode of the fault alarm. The menu item appears as: “FLT NONLATCHING”
11 - The alarm relay energize state of the fault alarm. The menu item appears as: “FLT ENERGIZED”
12 - The target gas K factor. The menu item appears as: “GAS FACTOR #.##”
13 - The calibration gas K factor. The menu item appears as: “CAL FACTOR #.##”
14 - The calibration gas level setting. The menu item appears as: “CalLevel @ xx%”
15 - Identif ication of the RS-485 ID number setting. The menu item appears as: “485 ID SET @ 1”
16 - The estimated remaining sensor life. The menu item appears as: “SENSOR LIFE 100%”
c) Exit back to normal operations by holding the programming magnet over “PGM 2” for 3 seconds, or automati-
cally return to normal operation in 30 seconds.

3.10.1 Alarm Levels
Both alarm 1 and alarm 2 levels are factory set prior to shipment. Alarm 1 is set at 20%; alarm 2 at 40%. Both
alarms can be set in 1% increments from 10 to 90%. The following procedure is used to change alarm set points:
a) First, enter the programming menu by holding the programming magnet stationary over “PGM 2” for 30 sec-
onds until the display reads “VIEW PROG STATUS”, then withdraw the magnet. At this point you can
scroll through the programming menu by momentarily waving the programming magnet over “PGM 1” or
“PGM 2”. The menu options are: View Program Status, Set Alarm 1 Level, Set Alarm 2 Level, Set Gas Factor,
Set Cal Factor, and Set Cal Level.
b) ALARM 1 LEVEL From the programming menu scroll to the alarm 1 level listing. The menu item appears as:
“SET ALARM 1 LEVEL”. Enter the menu by holding the programming magnet stationary over “PGM 1”
for 3 seconds until the display reads
“SET ALM1 @ 20%”, then withdraw the magnet. Use the programming
