  • Page 5: Introduction

    Section 1. Introduction 1.1. Overview The MGS Series controllers provide local alarm status indications (via multi-colored, per-channel LEDs) as well as single-level or dual-level digital (relay) alarm outputs based on 1, 2, 4, or 6 input signals and 1 or 2 user-definable set-points.

  • Page 7 MGS Series Controller Manual Figure 2. Sample Configurations (4,6-Channel) MGS Controllers have either one or two relay outputs: one for single- level alarm controllers (“Alarm”), and 2 for dual-level alarm controllers (“Alarm High” and “Alarm Low”). Unlike the alarm LEDs that provide a channel-by-channel alarm status of each incoming transmitter’s signal,...

    MGS Series Controller Manual Figure 3. Sample Front Panels Showing Status LEDs For dual-alarm configurations, the Alarm Low relay output “trips” or “energizes” if any of the inputs exceed the alarm threshold set by the low alarm pot. Similarly, the Alarm High relay output “trips” or “energizes” if any of the inputs exceed the alarm threshold set by the high alarm pot.
