A Quick Guide to the Use of this Instruction Manual
Your BA578C has been factory set to the requirements specified on your purchase
order. If no requirements were given, the instrument will be supplied with default
settings i.e. 3 wire RTD input; high resolution display in °C; 4 to 20mA output
corresponding to an input and display of 0.0 to 100.0°C.
If the BA578C is set to your requirements before putting it into use you should refer to:
Section 3 Electrical System Design
Section 4 Installation
Section 2.1 Controls
If optional alarms are fitted you should refer to Section 10. You will also find the 'Trim'
menu described in Section 6 useful if you wish to calibrate the complete control loop.
If the BA578C has been supplied with default settings and you wish to change these you
will need to refer to:
Section 5 Programming and Calibration
This section explains the programme functions of the front panel push-buttons and leads
you through the various stages of programming the unit. Among the sub-divisions of
Section 5 you will find information on setting up for
Section 6.3 Themocouple input
Section 6.4 Resistance thermometer input
Section 6.5 Voltage input
A word of warning:
Section 5.8 explains how you can calibrate the unit's internal
references. It is only necessary to carry out this operation if you will be using these
internal references to calibrate the instrument display,
i.e not using an external calibrator,
and then only annual or less frequent adjustment is required.
It is not necessary to
calibrate these references before putting the BA578C into operation,
we've already
done that for you. For this reason the calibration section of the programme menu is
protected by an additional security code. You should only enter this section of the
programme if you are sure that you want to carry out this calibration.
By following the notes in this manual you should be able to set up your BA578C without
any problem. If you do run into difficulties however Section 9 provides some guidance
on typical problems you may find during commissioning. If you still have difficulties
please contact our Sales Department (01462 438301). Our Sales Engineers will be able
to talk you through the the procedure.
