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 ZrO2 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 ZrO2 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:
