If necessary, consult factory for further suggested cable types. IMPORTANT Det-Tronics recommends the use of shielded cable (required by ATEX) to prevent external electromagnetic interference from affecting field devices. IMPORTANT For best fault isolation performance, the maximum LON wiring length should not exceed 1600 feet (500 meters). - Page 53 CONFIGURATION AND OPERATION Configuration of the EQP LS2000 is accomplished using Det-Tronics Safety System Software (S that is running on the EQP Operator Interface Station (OIS). The LS2000 should be configured as a Line-Of-Sight Gas Detector (LS2000). 95-8714...
- Page 54 Supported gas types for the LS2000 include Methane (Default), Propane, and Butane. The range for LS2000 high and low alarms is 0.5–3.0 LFL-m. The beam block delay time can be set from 60–3600 seconds. Alarms can be set for latching or non-latching operation. The real time clock in the LS2000 receiver is automatically set by the LON network approximately once per hour.
- Page 55 ONBOARD HART INTERFACE The on-board HART interface is functional on the EQP LS2000, however, it should not be used to select the gas type, alarm levels, or the beam block delay time because the LON will overwrite these values. All EQP device configuration should be performed using the S program.
- Page 56 SETTING NETWORK ADDRESSES Overview of Network Addresses Each IR gas detector on the EQP LON must be assigned a unique address. Addresses 1 to 4 LS2000 are reserved for the EQP controller. Valid addresses for field devices including gas detectors LS2000 are from 5 to 250.
- Page 57 LS2000 Address Switches Address switches for are located within the device enclosure. Refer to Figure G-2 for switch LS2000 location. WARNING Disassembly of the LS2000 housing and removal of the front electronics module from the bulkhead is required to gain access to the network address switches. Power should be removed from the detector before disassembly.
- Page 58 Switch Access Procedure NOTE It is strongly recommended to document all LS2000 gas detector network addresses as well as the addresses of all other LON devices on the Address Identification Chart before disassembling and programming the LS2000 gas detectors. Removal of the retaining ring and the front electronics module of the LS2000 IR gas detector from the bulkhead is required in order to gain access to the network address DIP switch.
