INTRODUCTION Configuring the instrument can take up to a couple of hours and consists of
the following operations:
1. Power supply voltage selection - select from either 110 or 220V supply.
2. Apply power - switch the power ON and observe the power supply rail
indications.
3. Alignment - optically align the transmitter and receiver units using the
integral adjustable mounts*.
4. Gain adjustment - adjust the gain within the receiver head and the
signal processor*.
5. Operating parameters - set the operating parameters within the
micro-processor for correct instrument operation.
6. Calibration - calibrate to a zero or an estimated gas concentration*.
7. Current output calibration - calibrate the analog current loop output.
8. Record the set-up and calibration data - it is strongly recommended that
the operating parameters are recorded in Table 3-1, and the calibration
data in Table 3-2.
NOTE
*These operations are preferably conducted when a clean stack condition
exists.
SAFETY
CONSIDERATIONS
The mains power is supplied to the whole system via the power supply unit. If
any servicing or rewiring is to be performed ensure that the power supply is
isolated. For configuring the CCO 5500, the system needs power,
compressed air to the air purges and the isolating valves (if used) to be open.
