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 plantoperation. It is intended for use in small to medium food storageoperations (for example a small supermarket) where compliancewith the Food Hygiene Regulations is to be demonstrated.

Designed for operational simplicity, the system once configuredwill display the status of each input point. Further details on anyaspect of the operation of the installation are available via thekey pad. In addition there is the ability for authorised personnelto make adjustments to the monitoring settings. Historical data isstored within the system and may be viewed or printed on aregular basis. The data is accessible both on and off-site via theexternal 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 untrainedpersonnel, in a matter of minutes. At power up, the programmer is prompted to make a few selections, all driven by easy menuoptions and icons.

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

Safety

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

Validity

This document was made in October 2001 and applies to Danfoss Micromon with software version B2.2.

When the Micromon initially powers up the 'Easy Setup' procedure will start as follows.


System Overview The Micromon consists ofa central monitoring unitwhich can monitor up to 16local sensors or inputswhich are usually locatedadjacent to the equipmentin question for examplespecific refrigerated areas(chiller cabinets, freezers,cold rooms or plantrooms). The precise layoutand configuration of thesesensors are specific toeach installation, and it isnot necessary for a typicaloperator to be familiar withthe operation of thesensors.

The Micromon provides audio and visual alarms whenever an input exceeds itspre-set alarm levels. The system can be pre-set to dial-out using a digital dialler orvia a modem whenever an alarm occurs (via "extended setup menu").

Security is provided by having passcode access to the protected settings. In thecase of mains failure, an alarm is triggered after a delay. The system can be pre-set to dial-out to an external telephone number if required.The Micromon will always FAIL SAFE (except for modem dailout).

If hard copy details of the monitor readings are required, a parallel printer port isprovided which can be connected to an ESC/P2 Epson compatible parallel printer.

Use this option to select the modem dialout settings. From the Extended Menu,select Modem Dialout Setup.

When connected to a modem, the Micromon is able to make telephone calls to upto five pre-programmed numbers whenever an alarm is detected (see AlarmActions section). Alternatively, individual alarms detected for a particular point canbe routed to a particular telephone number. It can also call a radio pager to alert aduty engineer. Three types of pager can be supported - Tone only, Numeric andAlphanumeric. The message that is sent can also be defined.Note: Support for the TAP pager protocol may vary from country to country.

Use the ‘ ’ or ‘ ’ keys to scroll through the dialout numbers and complete thefields for each device as described below:

Use this field to specify the type of device which is connected to the specifiedtelephone number. The options are as follows:

NO DIAL Indicates the Micromon will not dialout.

GSM SMS Indicates that a RS232/GSM modem device is connected. Sendstext messages to a GSM mobile phone and receives messages.

For information on this feature refer to document FunctionalDescription RC.8A.M.

DOWNLOAD Indicates that a computer is connected (directly or remotely)running Danfoss Central Station software. If the line is busy,the telephone number will be dialled up to four times (8 bit, No

Parity, 1 Stop Bit).

AKM Indicates that a computer is connected (directly or remotely)running Danfoss 'AKM' software. If remotely, dialout attempts willcontinue and after every 10 attempts the alarm relay will reset themodem.Note: Modem must be wired in conjunction with the alarm relay

(refer to appendix A).

BEEPER Indicates that a beeper type pager is connected. The systemdials the appropriate telephone number and then disconnects.

As there is no security associated with this option, the telephonenumber is always dialled twice unless the busy tone is received.

MESSAGE7 Indicates that a 7 bit modem is connected with a printer attached.(7 bit, Even Parity, 1 Stop Bit) (normally used in France).

MESSAGE8 Indicates that a 8 bit modem is connected with a printer attached.(8 bit, No Parity, 1 Stop Bit) (normally used in UK).

PAGER7S Indicates that a TAP 7 bit protocol pager is connected which candisplay a message. The message sent is defined on the Pager

Info line (7 bit, Even Parity, 1 Stop Bit).PAGER7M Identical to PAGER7S but sends message up to 4 times.

PAGER8S Indicates that a TAP 8 bit protocol pager is connected which candisplay a message. The message sent is defined on the Pager

Info line (8 bit, No Parity, 1 Stop Bit).

PAGER8M Identical to PAGER8S but sends message multiple times.

Enter the appropriate telephone numbers for each of the devices used. If acomma ‘,’ is inserted before the number, a delay of between 2 and 4 seconds willbe inserted between the modem picking up the line and dialling. If a ‘w’ is insertedbefore the number, the modem will wait for the secondary tone before dialling.

For a message to be sent to a pager, two items of information must be supplied inaddition to the TAP Pager server telephone number.

1. The pager I/D, this is normally marked on the pager.

2. The text message to be sent to the pager.

Text codes are available that add other information into the message. Thesecodes are as follows:

\S Sends the Store Name.\A Sends the Last Alarm Message\C Sends a count of alarms and muted alarms in the

format 2/4.\R Sends the Carriage Return (CR) character.\L Sends the Line Feed (LF) character.\\ Sends the \ character.// Sends the / character.\N Sends output name.

A typical text string will take the form:

123456\RAlarm at \S = \A\R

This page info string would cause pager '123456' to receive a message in the form"Alarm at Danfoss Superstore = 24 Fresh Fish 6.4 Hi>6.0"The pager info field is limited to a maximum of 30 characters

Use the ‘ ’ or ‘ ’ keys to select the option of the modem dialling out 'AlarmsOnly' or 'Alarms and Cleared Alarms'.

Appendix A

'AKM' Call Type

Background The Danfoss AKM has been updated to allow it to receive alarms from m2units. However the m2 alarm dialout procedure differs from the DanfossGateway in that it is not as tolerant of faulty telecommunication equipment.The m2 would make repeated calls to try to transmit the alarm message upto a maximum of 8. This conformed to the current telecommunicationregulations when the procedure as defined.AKM will continue to try to transmit the alarm indefinitely. It can also controlthe power to the modem using one of it relays. It does this after ten failedattempts to dial-out and every 6 hours.The 'AKM' call type has been created to mimmic the same dialout as theAKM.

The m2 has two relays that are normally used for alarm indication. TheRelay 2 (REP ALARM) can be used to control the modem power. TheRelay is rated at 24V 1A max, so the low voltage power after the mainstransformer must be switched. Mains voltage MUST NOT be connected tothis relay.
