Introduction
TheMicromonhasbeen developed to provide a comprehensive,
yetsimple-to-usemeansofmonitoringandrecordingrefrigera-
tiontemperaturesandotheraspectsofrefrigerationplant
operation. Itisintendedforuseinsmallto medium food storage
operations(forexampleasmallsupermarket)wherecompliance
withtheFoodHygiene Regulations is to be demonstrated.
Designedforoperationalsimplicity, the system once configured
will display the status of each input point. Further details on any
aspectoftheoperationoftheinstallationare available via the
keypad. Inadditionthere is the ability for authorised personnel
tomakeadjustmentsto 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
externalmodemconnectionand alarm calls can also be gener-
atedifrequired.
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
optionsandicons.
Thefollowingsectionsprovide a descriptionoftheMicromon,and the remainderofthemanualprovides further detailonthe
configuration,operationandmaintenanceofthe system.Itis recommendedthattheappropriatepart(s)arestudiedbeforeany
attempt is made to use the system.

System Overview The Micromon consists of
acentralmonitoringunit
which can monitor up to 16
local sensors or inputs
whichare usually located
adjacenttotheequipment
inquestionforexample
specificrefrigeratedareas
(chillercabinets,freezers,
coldroomsorplant
rooms).The precise layout
andconfigurationofthese
sensors are specific to
eachinstallation,anditis
not necessary for a typical
operatortobefamiliarwith
theoperationofthe
sensors.
The Micromon provides audio and visual alarms whenever an input exceeds its
pre-set alarm levels. The system can be pre-set to dial-out using a digital dialler or
via a modem whenever an alarm occurs (via "extended setup menu").
Security is provided by having passcode access to the protected settings. In the
case of mains failure, an alarm is triggered after a delay. The system can be pre-
settodial-outtoanexternaltelephonenumberifrequired.

Appendix A
'AKM' Call Type
Background The Danfoss AKM has been updated to allow it to receive alarms from m2
units.Howeverthem2alarmdialoutprocedurediffersfromtheDanfoss
Gatewayinthatit isnotastolerantof faultytelecommunicationequipment.
The m2 would make repeated calls to try to transmit the alarm message up
toamaximumof 8. Thisconformedtothecurrent telecommunication
regulationswhentheprocedureasdefined.
AKMwill continue to try to transmitthe alarm indefinitely. It can alsocontrol
the power to the modem using one of it relays. It does this after ten failed
attempts to dial-out and every 6 hours.
The 'AKM' call type has been created to mimmic the same dialout as the
AKM.
The m2 has two relays that are normally used for alarm indication. The
Relay 2 (REP ALARM) can be used to control the modem power. The
Relay is rated at 24V 1A max, so the low voltage power after the mains
transformer must be switched. Mains voltage MUST NOT be connected to
thisrelay.
