1. The System The EnviroMon system is designed for long term recording of data from a number of locations The system offers the following features permanent retention of recorded data on PC wide range of data display and analysis options easy to use software telephone style connections for easy installation modular system for easy upgrades a wide range of options to report alarm conditions support for remote data download modem GSM IP etc The Equipment The main components of an EnviroMon system are e acomputer e alogger e anumber of converters e alarm options The computer performs the following functions using the EnviroMon for Windows program e configuring the system e long term storage of data e display print and analysis of recorded data The computer talks to loggers using one of the following methods e using a direct connection to a local logger e via a telephone modem to a logger on a remote site e using a radio link for short range connection to sites not serviced by telephone e via a GSM telephone for remote or mobile applications e viaan IP network ideal for companies that already have a computer network The logger stores data continuously even when the computer is turned off or disconnected or the mains fails The logger connects to a number of converters that take measurements The converters can be up to 400 metres away from the logger and are connected using a single low cost telephon2. C The second display shows you how long the problem has been active in hours and minutes In some installations the temperature may go out of range during a defrost cycle The logger is programmed not to sound the alarm until a temperature stays out of range for more than a pre specified period the same time as a normal defrost interval Ifa sensor is out of range but the logger is programmed not to sound the alarm yet or if the logger has sounded the alarm and a user has cancelled the alarm the logger shows a black rectangle in the bottom right hand corner of the display EL005 Logger without display The EL005 logger has no display or buttons and so it can only be used with a computer The EL005 does not have an internal alarm if you need an audible alarm connect an EL006 audible alarm unit to the network Connections The logger has four sockets on one end e around DC power socket the cable from the mains adapter supplied with the logger plugs in here e two square network sockets e a D shaped serial port socket which connects either to a computer serial port or to a printer using the serial port adapter supplied The logger also has a red light LED next to the serial port Batteries The EL005 logger has internal re chargeable batteries These batteries are kept topped up whilst mains power is available and will keep the system running for up to 24 hours during a mains power failure The ELO18 dialer adapter battery ba
