SECTION 2. GENERAL INFORMATION
2.1Scope
This manual provides information about the installation, operation, and maintenance of the Programmable Logic Controller Health Monitoring and Reporting (PLCHMR) System manufactured by Honeywell.
2.2General Description
The PLCHMR system is a retrofitable health monitoring and reporting system for Honeywell’s high intensity flashing white obstruction lighting system. A majority of the system’s functionality is contributed by the PLCHMR module. It is designed for use with the StrobeGuard, Model SG-60E High Intensity Obstruction Lighting System. The system is designed and manufactured in compliance with Federal Aviation Administration Advisory Circular 150/5345-43E. The PLCHMR system will monitor and report on up to 24 flash-heads controlled by a single controller at distances up to 2500 feet.
The PLCHMR System module is shown in Figure 2.2-1. The major components of the retrofit kit consist of the following:
•PLCHMR System Module P/N 40002083-001
•Model SGC-60 Master Controller replacement Micro-Controller Unit (MCU P/N 40002085-001)
•Model SGF-60 Flash-head replacement micro-controller units (one for every flash head P/N 40002084-001)
2.2.1PLCHMR System Module
The PLCHMR module (see Figure 2.2-1) is a configurable microprocessor-based system that monitors a StrobeGuard, Model SG-60E High Intensity Obstruction Lighting system via the RS485 control and status network. The PLCHMR outputs alarm status via dry contact relays to a remote alarm monitoring system. The PLCHMR module is preassembled and consists of three circuit card assemblies affixed to mounting plate. The module provides 2 wiring harnesses that must be attached to two terminal connectors located on the Model SGC-60 Master Controller (See Figure 2.2-2).
2.2.2Model SGC-60 Master Controller replacement Micro-Controller Unit
The Master Controller (see Figure 3.3-1) is a micro-controller based system that controls the flash interval and timing, flash intensity, and monitors the complete StrobeGuard system via the StrobeGuard RS485 control and status network (SCSN). The MCU must be replaced during the installation process in order for the PLCHMR to monitor the SCSN. Software in the new micro controller changes the baud rate of the SCSN from 300 to 9600 baud. A replacement MCU is provided as part of the upgrade kit (P/N 40002085-001 and replaces P/N40000328-001).
