1. PRESENTATION STANDGAS HC & HC PRO are stand-alone detectors for explosive gases using catalytic technology (pellistor) for a detection range from 0 to 100% LEL. Silicon vapours resistant sensors (HDMS) Available formats and gases STANDGAS HC Available for natural gas-methane, butane-propane, and hydrogen.
2. RELAY MODULE FUNCTIONING The stand-alone detectors STANDGAS HC and STANDGAS HC PRO are provided of a relay output with the following parameters: ON position OFF position Programming Activated Deactivated Initial status: Idle mode relay Instantaneous Retarded Relay disconnection type 5min.
4. PROGRAMMING AND GAS GROUP SELECTION STANDGAS HC & HC PRO detectors are provided with a microprocessor for functioning control. This is a great advantage due that, through software and adequate algorithms, these detectors can be reprogrammed at installation for auto- calibration and sensitivity auto-adjust without using gas.
CALIBRATION WITH GAS 1. Set the detector for Group 1, as it is described on page 7 (STANDGAS HC) and 8 (STANDGAS HC PRO). 2. Insert CECALIBR adapter into the detector and release a precise mixture of methane, at 2,5% v/v, equivalent to 50% LEL, with a 0,5l/min flow and adjust the GAIN potentiometer until the measuring instrument indicates 1.0V DC between TP+ and TP- terminals.
Its negligent installation or use will exempt DURAN ELECTRONICA from any responsibility on the damages caused to objects and/or people, and the fulfillment of the terms of this warranty.
