Summary of Contents for 3Com DIN Digital Indicator 59039-2

  • Page 1 -DIN DIGITAL INDICATOR PRODUCT MANUAL 59039-2...
  • Page 2 This manual comprises two volumes: Volume I: This supports normal operation of the 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 intended for use only by personnel who are trained, equipped and authorised to carry out these functions.

  • Page 3: Operating Instructions

    59039 -DIN DIGITAL INDICATOR 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.

  • Page 7 59039 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. Fig ure 2-1 FOUR-DIGIT DISPLAY In Operator Mode, this normally displays the process variable value. Using the Scroll key, the operator may view, in a sequence according to the Operator Mode Display Strategy parameter in Set Up Mode (see NOTES ON TABLE 3-1): (i) Cur rent maxi mum value at tained by pro cess vari able (since the maxi mum...

  • Page 9 59039 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. SENSOR BREAK INDICATION If a break is detected in the sensor circuit, the four-digit display will show: The reaction of the alarms to a detected sensor break is dependent upon the input type.

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. 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.
