A Quick Guide to the Use of this Instruction Manual
Your BA374C 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 BA374C is set to your requirements before putting it into use you should
refer to:
Section 4 Electrical System Design
Section 5 Installation
Section 2.1 Controls
If optional alarms are fitted you should refer to Section 11.
You will also find the 'Trim' menu described in Section 7 useful if you wish to
calibrate the complete control loop.
If the BA374C has been supplied with default settings and you wish to change
these you will need to refer to:
Section 6 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 6 you will find information on setting up for:
Section 6.3 Thermocouple input
Section 6.4 Resistance thermometer input
Section 6.5 Voltage input
A word of warning: Section 6.8 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 BA374C 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 BA374C
without any problem. However, If you do run into difficulties 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 procedure.
