A2.2 Setting and Change of Basic Parameters
This section describes the procedure taken to set and change the parameters for each block.
Obtaining access to each parameter differs depending on the configuration system used. For details,
refer to the instruction manual for each configuration system
Do not turn the power OFF immediately after parameter setting. When the parameters are saved to
the EEPROM, the redundant processing is executed for the improvement of reliability. If the power is
turned OFF within 60 seconds after setting of parameters, changed parameters are not saved and
may return to their original values.
Note 1: Block mode consists of the following four modes that are controlled by the universal parameter
that displays the running condition of each block.
Target: Sets the operating condition of the block.
Actual: Indicates the current operating condition.
Permit: Indicates the operating condition that the block is allowed to take.
Normal: Indicates the operating condition that the block will usually take.
Note 2: The followings are the operating conditions which the individual blocks will take.
Note: Refer to Appendix 1, “List of parameters for each block of the AV550G” for details of the Write Mode for each block.
A2.3 Setting the AI Function Blocks
Each AV550G contains three AI function blocks having independent parameters. Set up the
parameters of each AI block you use, individually as necessary.
The AI block performs the averaging oxygen concentration output calculation.
(1)-1. Setting the calibration range
Access the parameter to be set or changed.
Make setting or change in accordance with each parameter.
Set the Target of block mode (MODE_BLK) back to Auto (*Note 2) .
Access the block mode (MODE_BLK) of each block.

Set the Target (*Note 1) of block mode MODE_BLK) to Auto, Man or O/S (*Note 2)
according to the Write Mode of the parameter to be set or changed.
