m2 Version 3.11 Manual RS.8A.N5.02 © Danfoss 10-2007 3
Introduction
The m2 has been developed to provide a comprehensive, yet
simple-to-use means of monitoring, recording and control
refrigeration 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. A variety of ancillary control equipment may be in
use in such installations, each with its own specic requirements
in terms of interfacing and monitoring, and m2 can be congured
to work in such an environment.
Designed for operational simplicity, the system once congured
can display the status of each input point in turn with the
occurrence of any fault condition indicated immediately by
means of audible and visual alarms. 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 control and/or 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 o-site
via the external modem connection and alarm calls can also be
generated if required.
The following sections provide a description of m2, and
the remainder of the manual provides further detail on the
conguration, 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.
