Introduction

The Micromon has been developed  to provide a comprehensive,
yet simple-to-use means of monitoring and recording refrigera-
tion temperatures and other aspects of refrigeration plant
operation.  It is intended for use in small to medium food storage
operations (for example a small supermarket) where compliance
with the Food Hygiene Regulations is to be demonstrated.

Designed for operational simplicity, the system once configured
will display the status of each input point.  Further details on any
aspect of the operation of the installation are available via the
key pad.  In addition there is the ability for authorised personnel
to make adjustments to the monitoring settings.  Historical data is
stored within the system and may be viewed or printed on a
regular basis.  The data is accessible both on and off-site via the
external modem connection and alarm calls can also be gener-
ated if required.

The Micromon has been designed in such a way that programming of the system can easily be performed by untrained
personnel, in a matter of minutes. At power up, the programmer is prompted to make a few selections, all driven by easy menu
options and icons.

The following sections provide a description of the Micromon, and the remainder of the manual provides further detail on the
configuration, operation and maintenance of the system. It is recommended that the appropriate part(s) are studied before any
attempt is made to use the system.

Safety

To  prevent accidents arising from improper handling, installation or operation, please read this manual carefully.
