ULTRAFLOW 150 GAS FLOW AND TEMPERATURE MONITOR
INITIATION AND CONTROL OF CALIBRATIONS AND MODES OF OPERATION
The system calibration may be initiated and controlled from the serial port. TIE1 and TIE2 may
be controlled independently when both are present. The following command string may be used.
The command string for TIE1 is as follows: 998, "command", 998, "command" <CR> <LF>
The command string for TIE2 is as follows: 999, "command", 999, "command" <CR> <LF>
The value for "command" is chosen from the following list of commands.
Command Number Action resulting from specified Command Number
1 NORMAL
2 SPANHIGH
3 SPANLOW
4 ZERO
5 DIAGNOSTIC (this command should not be used)
6 TEST_FULL_SCALE (for MIO 4 to 20 mA outputs)
7 TEST_MID_SCALE (for MIO 4 to 20 mA outputs)
8 TEST_ZERO_SCALE (for MIO 4 to 20 mA outputs)
9 CAL_CYCLE (the TIE will complete a full calibration
cycle typically consisting of both Zero and Span High
modes and then returning to Normal operation.
10 PUT_OUT_OF_SERVICE (may be used to indicate
when maintenance is done on the monitor)
11 PUT_IN_SERVICE (may be used to indicate when the
monitor is finished having maintenance done on it)
12 RESET (sends a command to reset the TIE)
13 RECONFIG (sends a command to reconfigure the FPGA)
•
MIO stands for the printed circuit board (Multi Input Output) commonly used to interface with computers
via isolator inputs, relay outputs and analog outputs)
•
TIE stands for the Transducer Interface Enclosure where the electronics which makes the measurement is
located.
•
FPGA stands for Field Programmable Gate Array which is an I.C. within the TIE.
For example to request the TIE1 to go into the SPANHIGH mode the following command line
would be used.
998, 2, 998, 2 <CR> <LF>
If the following command line is given to the ENHANCED REMOTE PANEL, it will list the
commands available for the calibration input command line as shown in the above table.
997 ? <CR> <LF>
