8.4 Sensor Information
The Sensor Information page shown in Figure 7 4 displays important values for the Smart Sensor installed. The TXP-
WTA Sensor Transmitter Smart Sensor interface automatically detects new Smart Sensor Modules and updates this
page any time a new sensor is installed.
NOTE: Type, Span, Zero, SN (Serial Number) and Born On date are set at the factory and may not be modified.
•
Type indicates what kind of sensor is plugged into this TXP-WTA Sensor Transmitter channel.
•
Span / Zero indicate the nominal gas range for this sensor but not necessarily what the user's range must be.
For example, the nominal Span of an H2S sensor might be 100 ppm but the user may decide to set his TXP-
WTA Sensor Transmitter Span for only 50 ppm.
See Preamp Gain Section 8.5.2 to learn how to set the TXP-WTA Sensor Transmitter span for a different
range than the Smart Sensor's nominal Span.
•
Born On Date shows when the sensor was originally configured at the factory.
Last Cal date updates each time the CAL MODE is performed (see Section 6.3).
•
8.5 Technicians Only
WARNING: USERS OF THESE MENUS MUST HAVE A DETAILED UNDERSTANDING OF THEIR FUNCTIONS. MONITORING
OF TARGET GASES, PROCESSING OF ALARMS, AND WIRELESS COMMUNICATIONS SHOULD NOT BE RELIED UPON
WHILE EDITING THESE MENUS! BACK UP THE CURRENT CONFIGURATION PRIOR TO ALTERING ANY TECHNICIAN
MENUS IN CASE RESTORE IS REQUIRED LATER (SEE SECTION 8.2.10).
The TECHNICIAN ONLY Menu group in Figure 8-5 contains items that are factory configured depending upon the
type of sensor input connected to the TXP-WTA Sensor Transmitter. They should not be tampered with after
installation. If configured incorrectly, some items will prevent accurate monitoring of target gases. Access requires
a special key sequence of four consecutive UP keystrokes to prevent accidental modification of critical items.
