2 OPERATOR MODE

2.1 Introduction

Operator Mode (Level 1) is the normal day-to-day mode of the instrument.
Frames displayed in Level 1 are determined by the indicator functions which are

selected during configuration of the instrument – see Section 4.

Note. Only the operating frames relevant to the configured functions are

displayed in Operator Mode.

The three indicator functions are:

• Standard Indicator – page 8

• Indicator with Totalization – page 9

• Indicator with Max./Min./Average – page 11

4 CONFIGURATION MODE

4.1 Introduction

The Configuration Mode comprises two levels (3 and 4) as shown in Fig. 4.2.
Configuration Level 3 is divided into four frames. For most simple applications, it is

only necessary to set up the parameters in the first frame.

Note.

When in the configuration level:

• All the LED indicators flash.

• All relays and logic outputs are turned off.

• The analog output reverts to 0% (4mA) output level.

4.2 Accessing the Configuration Mode – Fig. 4.1

To access the Configuration Mode, set the security switch to the 'Configure'
position (Levels 1 and 2 cannot be accessed from this setting). When the
configuration parameters are programmed, reset the security switch to the 'Normal'
position and the operating page is displayed automatically .
