8 -DIN DIGITAL INDICATOR PRODUCT MANUAL 59039-2
PREFACE This manual comprises two volumes: Volume I: This supports normal operation of the 18 -DIN Digital Indicator. In normal operation, all actions taken by the user are to be in front of the panel. Volume II: This supports the installation, commissioning and configuring of the 18 -DIN Digital Indicator. It is intended for use only by personnel who are trained, equipped and authorised to carry out these functions.
1 8 59039 -DIN Digital Indicator Product Manual - Volume I 1 8 -DIN DIGITAL INDICATOR PRODUCT MANUAL VOLUME I OPERATING INSTRUCTIONS In normal operation, the operator must not remove the Indicator from its housing or have unrestricted access to the rear terminals, as this would provide potential contact with hazardous live parts. Installation and configuration must be undertaken by technically competent servicing personnel. This is covered in Volume II of this manual.

1 8 59039 -DIN Digital Indicator Product Manual - Volume I Section 2 Operator Mode SECTION 2 OPERATOR MODE 2.1 INTRODUCTION The Operator Mode is the normal mode of the Indicator, once it has been set up and configured as required. The front panel displays, indicators and keys are shown in Figure 2-1. Figure 2-1 2.2 Front Panel Controls, Displays and Indicators FOUR-DIGIT DISPLAY In Operator Mode, this normally displays the process variable value.
Section 2 Operator Mode 1 8 -DIN Digital Indicator Product Manual - Volume I 59039 (iii) Time elapsed in the Alarm 1 active condition (units display shows ). The display is in the format mm.ss [mm = minutes, ss = seconds] or mmm.s [mmm = minutes, s = seconds (tens)]. If elapsed time is greater than 999 minutes 59 seconds, display will show: NOTE: This does not include time when Alarm 1 is latched but alarm condition is cleared (iv) Alarm 1 value (units display shows or, if only Alarm 1 present, ).
1 8 -DIN Digital Indicator Product Manual - Volume I 59039 2.5 Section 2 Operator Mode OVER-RANGE/UNDER-RANGE DISPLAYS If the process variable attains a value higher than the input scale maximum limit (over-range) or lower than the input scale minimum limit (under-range), the upper display will show: for the over-range condition and: for the under-range condition. 2.
Section 2 Operator Mode 1 8 -DIN Digital Indicator Product Manual - Volume I 59039 for two seconds, indicating that the latched alarm has been reset. The latched Alarm 1 can be reset only if the original alarm condition has been cleared; this reset has no effect whilst the alarm condition prevails. 2.9 VIEWING THE HARDWARE DEFINITION CODE The operator may view the current Hardware Definition Code setting in the four-digit display by simultaneously depressing the Lower and Scroll keys.

1 8 59039 -DIN Digital Indicator Product Manual - Volume II Section 1 Installation SECTION 1 INSTALLATION 1.1 UNPACKING PROCEDURE 1. Remove the instrument from its packing. The instrument is supplied with a panel gasket and push-fit fixing strap. Retain the packing for future use, should it be necessary to transport the instrument to a different site or to return it to the supplier for repair/testing. 2. Examine the delivered items for damage or deficiencies.
1 8 -DIN Digital Indicator Product Manual - Volume II Section 1 Installation Figure 1-2 59039 Main Dimensions To panel-mount the instrument: 1. Insert the rear of the housing through the cut-out (from the front of the mounting panel) and hold the instrument lightly in position against the panel. Ensure that the panel gasket is not distorted and that the instrument is positioned squarely against the mounting panel. Apply pressure to the front panel bezel only.
