9.4 Calibration Frequency
In most applications, monthly to quarterly calibration intervals will assure reliable detection. However,
industrial environments differ. Upon initial installation and commissioning, close frequency tests should be
performed, weekly to monthly. Test results should be recorded and reviewed to determine a suitable
calibration interval.
10.0 STATUS OF PROGRAMMING: SOFTWARE
VERSION, ALARMS, CALIBRATION LEVEL,
RS-485 ID, AND SENSOR LIFE
The programming menu has a programming status listing that allows the operator to view the gas, range, and
software version number of the program, as well as the current alarm settings, calibration gas level setting, RS-
485 ID number, and estimated remaining sensor life. The programming menu also allows the changing of
alarm levels (see section 11.0) and the programming of the calibration gas level setting (see section 9.2).
The following procedure is used to view the programming status of the sensor:
1) First, enter the programming menu by holding the programming magnet stationary over “PGM 2” for 30
seconds 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, and Set
Cal Level.
2) 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 five second intervals, through the following
information before returning back to the “VIEW PROG STATUS” listing.
a) The software version number.
b) Range is ###
c) The alarm set point level of alarm 1. The menu item appears as: “ALM1 SET @ xxPPM”
d) The alarm firing direction of alarm 1. The menu item appears as: “ALM1 ASCENDING”
e) The alarm relay latch mode of alarm 1. The menu item appears as: “ALM1 NONLATCHING”
f)
The alarm relay energize state of alarm 1. The menu item appears as: “ALM1 DE-ENERGIZED”
g) The alarm set point level of alarm 2. The menu item appears as: “ALM2 SET @ xxPPM”
h) The alarm firing direction of alarm 2. The menu item appears as: “ALM2 ASCENDING”
i)
The alarm relay latch mode of alarm 2. The menu item appears as: “ALM2 LATCHING”
j) The alarm relay energize state of alarm 2. The menu item appears as: “ALM2 DE-ENERGIZED”
k) The alarm relay latch mode of the fault alarm. The menu item appears as: “FLT NONLATCHING”
l)
The alarm relay energize state of the fault alarm. The menu item appears as: “FLT ENERGIZED”
m) Calibration gas level setting. The menu item appears as: “CalLevel @ xxPPM”
n) Identification of the RS-485 ID number setting. The menu item appears as: “485 ID SET @ 1”
o) The estimated remaining sensor life. The menu item appears as: “SENSOR LIFE 100%”
3) Exit back to normal operations by holding the programming magnet over “PGM 2” for 3 seconds, or
automatically return to normal operation in 30 seconds.
