A Quick Guide to the Use of this Instruction Manual
Your BA574C 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 BA574C 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 BA574C 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 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 5.3
Themocouple input
Section 5.4
Resistance thermometer input
Section 5.5
Voltage inputs
A word of warning:
Section 5.8 explains how you can calibrate the instrument'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 unit 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 BA574C without any
problem. If you do run into difficulties however Section 8 (Maintenance) provides some
guidance on typical problems you may find during commissioning. If you still have
difficulties please contact our Sales Department (01462 438301). Our Sale
s Engineers
will be abl
e to talk you through the the procedure.
