6.3 Routine maintenance
It is advisable to check the general condition of the installation
occasionally to make sure that no damage or deterioration has
occurred. The following should be checked at least once every two
years (more frequently for particularly harsh environments):
1. Modules are of the types specified in the relevant documentation
and are mounted in the correct positions on the associated
backplanes.
2. Modules and hazardous area connectors are correctly and
legibly tagged; that the connectors are plugged into the matching
modules and that the tag details given comply with the relevant
documentation.
3. Modules and hazardous area connectors are securely plugged
into their matching sockets.
4. All connections to the backplane, and to the hazardous area
connectors, are properly made.
5. Connecting cables to backplanes and to the hazardous area
connectors are of the specified type and rating. They should be
correctly routed and segregated and not frayed or otherwise
damaged.
6. Cable screens are properly earthed
Caution: It is strongly recommended that users only
undertake the tests and routine maintenance described in
sections 6.2 and 6.3.
If a module is faulty, repairs or modifications
MUST NOT be made as these may affect the intrinsic
safety of the module. For repair or replacement, any faulty units or
backplanes should be returned to the MTL Group company or the
representative from which they were purchased.
7 SOFTWARE CONNECTIVITY
7.1 Introduction
The MTL HART system provides access from a PC to the HART field
devices for configuration, diagnostics and the monitoring of device
performance. HART devices may be selected for regular status
monitoring, and an alert issued if the status changes.
In addition, MTL’s HART connection system supports dedicated
software packages for valve positioners to optimise valve maintenance
schedules.
7.2 Communication modes
The MTL4841 supports two communication modes:
MTL mode and
Arcom mode
to suit the various types of Instrument Management Software package
available.
MTL mode is used by Applied System Technologies Cornerstone
software and several valve manufacturers diagnostic software.
Arcom mode is used by Emerson AMS software and also several valve
manufacturers diagnostic software.
MTL4841s are therefore available in the following formats.
•
•
Part Number Configuration

Software package
MTL4841 MTL mode Cornerstone
Valvelink (stand alone)
HART OPC server
Fieldcare
FDM
MTL4841-AMS Arcom mode AMS suite Ver1.4 - 6.2
Fieldcare (with DTM*)
Pactware (with DTM*)
FDM (with DTM*)
MTL4841-AMSv7 Arcom PLUS mode AMS suite Ver 7 or later
MTL4841-PRM Arcom mode PRM
Standard MTL4841’s are shipped pre-configured to MTL mode. Units
ordered as MTL4841-AMS are pre-configured to Arcom mode and
have AMS written on the batch code label for identification.
*
Some software packages based on the FDT Specification will require the
MTL4840 communications DTM.

7.3 Software setup
Having connected the MTL4841/MTL4842 system, as described in
this manual, set up the software as described in the software user’s
manual.
