10.2 Overview
The Environmental Manager uses analog sensors to monitor conditions such as temperature,
humidity, and battery voltage. In addition, the Environmental Manager can also monitor change
of state activities such as contact closures. External devices like auxiliary fans or alarms can be
controlled by the ASG Guard’s two solid state relays in conjunction with external power relays.
The ASG Guard/ASG Guard Plus converts analog input signals to digital signals used to generate
internal events. For information on how to associate internal events with Action Routines, refer to
Chapter 14.
10.3 ASG Guard/ASG Guard Plus Series Environmental Manager Options
Below is an outline of the Environmental Manager Options for the ASG Guard/ASG Guard Plus
product line. Along with the differences listed here, there is also a difference in the interface
cable between the ASG Guard Plus and ASG Guard. The ASG Guard Plus uses an Amphenol
connector to access all environmental functions. The ASG Guard uses standard RJ45
connections for the 2 temperature probes and the 0-5 volt analog input. The solid state relays
use a 6 pin Euroblock connection, while the contact closures use a 10 pin Euroblock connection.
ASG Guard Plus (Base Unit) inputs to the Environmental Manager are listed below:
•
48-Volt Battery Monitor available with or without the optional 48V DC-DC converter.
•
One temperature Sensor: requires temperature probes required
•
Three 0-5 VDC analog inputs
•
Eight contact closures inputs
