Teledyne Analytical Instruments 26
Parity none
Stop Bits 1
Message Interval 2 seconds. When CRC opens
again, zero and span are done,
and the sample is being analyzed.
Range ID Relays: There are three dedicated Range ID relay contacts.
Three ranges are assigned to relays in ascending order—Low range is
assigned to Range 1 ID, Medium range is assigned to Range 2 ID, and
High range is assigned to Range 3 ID.
Network I/O: A serial digital input/output for local network protocol.
At this printing, this port is not yet functional. It is to be used in future
options to the instrument.
RS-232 Port: The digital signal output is a standard RS-232 serial
communications port used to connect the analyzer to a computer,
terminal, or other digital device. It requires a standard 9-pin D
connector.
The data is status information, in digital form, updated every two
seconds. Status is reported in the following order:
• The concentration in ppm or percent
• The range in use (HI, MED, LO)
• The span of the range (0-100 ppm, etc)
• Which alarms—if any—are disabled (AL–x DISABLED)
• Which alarms—if any—are tripped (AL–x ON).
3.4 Installing the Zirconium Oxide Sensor
The ZrO
2
sensor may not installed in the cell block when the
instrument is shipped. It must be installed before the analyzer is placed
in service.
When the ZrO
2
sensor needs to be installed or replaced, follow the
procedures in Section 5.2.
3.5 Testing the System
Before plugging the instrument into the power source:
