  • Page 13: Chapter 1: Introduction

    Chapter 1: Introduction Thank you for selecting the GSE Model 350/355 Intrinsically Safe Indicator. The Model 350 I.S. and Model 355 I.S. continue the GSE tradition of Excellence in Weighing. A properly installed and maintained Model 350 I.S. or Model 355 I.S. will provide many years of reliable, accurate performance.

  • Page 14: Hazardous Area Guidelines

    Hazardous Area Guidelines The GSE Models 350 I.S. and 355 I.S. instruments are approved by FM Approvals as intrinsically safe for use in hazardous areas. An intrinsically safe device has been proven through calculation and testing that it cannot produce enough electric or thermal energy under normal or fault conditions to cause ignition of flammable material present in the atmosphere.
  • Page 15 Class I, Division 1, Groups A, B, C & D Class I, Division 1 locations are those in which hazardous concentrations of flammable gases or vapors exist continuously, intermittently or periodically under normal operating conditions.

  • Page 31: Remote Display Connections

    The open circuit voltage across the remote key pins is +5 VDC. A closed switch will conduct about 0.25 mA. Therefore, a low-voltage switch with gold-plated contacts is recommended. A Mercury-wetted switch will also work well. A minimum contact duration of 100 ms is required. Once invoked, the selected remote key operation will not repeat until the contact is released and closed again.

Sealing And Audit Trails Most legal-for-trade installations will require the Model 350/355 I.S. to be sealed. A sealed indicator cannot be accessed for setup or calibration changes without breaking a physical seal or incrementing an event counter, thus providing evidence of tampering.
