(PCB). All components are located on the board. Powering up the SBA-5 The SBA-5 requires a 6-18V DC input to power up the analyzer. Power can be applied to 3 different connectors on the SBA-5 board (CN2, CN3 or CN4). See sections below for appropriate connections.
C and performed the first ZERO. SBA-5 Warm-up We recommend allowing the SBA-5 to warm up for at least 30 minutes to ensure best operation. For the first 10-15 minutes, warm-up messages are output via digital lines (RS232 and USB).
18. Power and Signal Ground Indicating LEDs There are a couple of LEDs located on the SBA-5 board to assist with system troubleshooting: LED1 HB Represents the ‘heartbeat’ of the SBA-5. It flashes at 5 Hz indicating that the system is operating properly.

“Auto-Zero” where CO2 free gas is periodically flushed through the sample cell. (See Measurement Principle on page 10. Normally this is done using a CO2 scrubber such as soda lime.

It is vital that both of these references are accurate. Recalibration Procedure 1. Power up the SBA-5 and connect it to your computer and execute the GAS software and allow the SBA-5 to warm-up for approximately 30 minutes. 2. To avoid excess pressure in the SBA-5 sample cell and possible damage to the analyzer, you must connect the sample line with a “T”...
The spare I/O pin on the terminal block CN3 and the I/O header CN4 can be set to different modes of operation. On power up or if a “J0” command is sent to the SBA-5, the spare I/O pin is a digital 0-5V output representing data valid.
SBA-5 will power-up in the desired mode. The SBA-5 main voltage input can be any voltage between about 6.5 V and 18 V. If only 6.5 V is supplied, then the 4-20 mA output will only be able to provide 20 mA output when the the total resistance of the wire leads and the data logger shunt is 300 Ohms or less.
If the command received by the SBA-5 is valid, then the command is returned to the PC as a response. If a command received by the SBA-5 is not valid, then an error message will be returned to the PC as a response. Commands that include a value or range must be terminated with a Carriage Return (CR) i.e.

Default is Short in which the autozero sequence is approximately 20 sec long. Longer duration zero cycles can be useful if the flow rate through the SBA-5 is lower than 100 ml/min or the measured gas concentration is above 10,000 ppm to insure fully purging measurement gas from the cell prior to recording a zero reading.
User should set USF to 1.00 prior to performing recalibration measurements. Note: U command was added in V2.04. See additional note at end about upgrading an SBA-5 from V2.03 and earlier to V2.04 or later. L<value>CR Low CO2 In [ppm] alarm. range: 0-100000 (floating point). In...

Any of the commands can be included in a text file created by a program such as Microsoft Notepad. This file can be downloaded to the SBA-5 by using the HyperTerminal menu item Transfer>Send Text File…. Command a zero operation before transferring the command file to ensure the maximum time until the next zero operation.
2.03 and below, the CO2 will read 0 until the User Scale Factor is set to 1.00. After upgrading the firmware, send the command “U1.00” to the SBA-5 to set the USF to 1.00, then send the command “X” to save the USF to non-volatile memory.
Maintenance Maintenance The SBA-5 is virtually maintenance free. If proper care is taken, the SBA-5 should last for many years. The user should make sure that the sample air is adequately filtered to protect the analyzer from dirt, dust, moisture, toxic gases, etc. In some PP Systems products, PTFE hydrophobic membranes with 3 micron pore size (Millipore FSLW-14200) are mounted into 12.5...
There is also a small “O” ring on each of the absorber end cap fittings. These should be in good condition. Replacement “O” ring and filter sets can be ordered from PP Systems if required. See figure below for location of “O” rings and foam pads. The white plastic filter disks are located on the black end caps inside the absorber column.

Pump The sampling pump provided by PP Systems is a “rotary vane” style pump and components wear with prolonged use and material from the vanes may build up within the pumps. The risk of this situation occurring can be minimized by regular pump servicing.
When finished, run the pump in air for at least 15 minutes to allow any residual alcohol to evaporate. Ideally, let the pump dry overnight before plumbing back up to the SBA-5. If the pump is reconnected prematurely, the soda lime in the absorber column will exhaust quicker than usual.
