From the
Set AutoSpan Level
text scroll, hold the magnet over PGM1 or PGM2 until the “
” prompt appears
and continue to hold the magnet in place for an additional 3-4 seconds (until the display starts to scroll “Set
Level”). The display will switch to “XX“(where XX is the current gas level). Swipe the magnet momentarily
over PGM2 to increase or PGM1 to decrease the AutoSpan Level until the correct level is displayed. When
the correct level is achieved, hold the magnet over PGM1 or PGM2 for 3-4 seconds to accept the new value.
The display will scroll “Level Saved”, and revert to “Set AutoSpan Level” text scroll.
Move to another menu item by executing a momentary hold, or return to Normal Operation via automatic
timeout of about 15 seconds (the display will scroll “Set AutoSpan Level” 4 times and then return to Normal
Operation).
3.5.3
Set Range
Set Range
is used to change full-scale ranges. This is selectable between 0-20, 0-50, and 0-100ppm. The
current range can be viewed in View Sensor Status using instruction given in Section 3.5.1 View Sensor
Status.
The menu item appears as: “
Set Range
”.
From the “
Set Range”
text scroll, hold the programming magnet over PGM1 or PGM2 until the “
” prompt
appears and continue to hold the magnet in place for an additional 3-4 seconds (until the display starts to scroll
“Set Range”). The display will then switch to “XXX“(where XXX is the current Range). Swipe the magnet
momentarily over PGM2 to increase or PGM1 to decrease the range Level until the desired range is displayed.
Hold the magnet over PGM1 or PGM2 for 3 seconds to accept the new value. The display will scroll “Range
Saved”, and revert to “Set Range” text scroll.
Move to another menu item by executing a momentary hold, or, return to Normal Operation via automatic
timeout of about 15 seconds (the display will scroll “Set Range” 7 times and then return to Normal Operation).
NOTE
: When switching between ranges, it may be necessary to readjust the AutoSpan Level.
3.5.4
Set Heater Power
Set Heater Power is used to set the each H
2
S sensor to the optimum operating temperature. This function is
performed during factory calibration of each TP-524D sensor assembly, and is not necessary during
installation. However, it is necessary to perform in the field if the plug-in H
2
S sensor is replaced, mounted
remotely from the Transmitter Module, or if the Restore Factory Defaults function has been executed.
The menu item appears as: “
Set Heater Power
”.
NOTE
: “Set Heater Power” is only necessary after new plug-in H
2
S sensor installation,
mounted remotely from the Transmitter Module, or after use of the “Restore Factory Defaults”
function. A full 3-4 second magnet hold on PGM1 or PGM 2 is required to execute this
function.
From the “Set Heater Power” text scroll, hold the programming magnet over PGM1 or PGM2 until the “
”
prompt appears and continue to hold the magnet in place for an additional 3-4 seconds (until the display starts
to scroll “Setting Heater”). After scrolling “Setting Heater”, the sensor will adjust the Heater power. The
sequence should require about 2-minutes. When the cycle is complete, the display will revert to the “Set
Heater Power” text scroll.
NOTE
: If the sensor cannot adjust the heater power within 3 minutes an error message, “Can’t
set, Reverting to Default”, will be scrolled. Refer to section 5 Troubleshooting Guide.
