1 About this document
This document is a translation of the original operating instructions for the product MSI 420.TMC-03. It
describes handling of the discontinued TMC 66 (Leuze article no. 50082121) and how to replace the TMC
66 for the substitute MSI 420.TMC-03. The latter is also referred to below as the
TMC 66 Legacy solution.

2 System overview
The TMC 66 Legacy system is based on the MSI 400 safe compact control from Leuze electronic. The
system is a substitute for the TMC 66 (Leuze electronic article no. 50082121) and is used only as a
replacement solution.
The solution essentially consists of a hardware component and software functionality specifically config-
ured for this application. The latter emulates the original behavior of the TMC 66, thus enabling simple
replacement of the old device.
The software functionality is already stored on the supplied memory card on delivery. The program has
already been verified so that the program sequence is executed automatically as soon as the
MSI 420.TMC-03 is connected to the supply voltage and has completed a self test.
Owing to the preconfigured memory card, it is not necessary to make any changes to the logic program
during commissioning.
If the memory card needs to be changed, this must always be done by a Leuze electronic service techni-
cian.
If Leuze electronic explicitly instructs you to change the memory card (e.g. in the event of an update), this
can be done by a competent person, taking the relevant work instructions into consideration.
2.1 Features
Four different operating modes are available:
• Operating mode 1: Start/restart interlock active; contactor monitoring inactive
• Operating mode 2: Start/restart interlock inactive; contactor monitoring inactive
• Operating mode 3: Start/restart interlock active; contactor monitoring active
• Operating mode 4: Start/restart interlock inactive; contactor monitoring active
The respective operating mode is selected by means of a wire bridge, see table 4.2 "Selection of operating
mode".
Three signal outputs for indicating the status (for details, see chapter 5 "Diagnostics messages")
•Error
• Safety on
• Error indication
NOTE
During development of the replacement solution, great importance was placed on 1:1 exchangeability
(wiring and functionality) with the TMC 66. Nevertheless, some aspects with respect to the handling and
system behavior of the replacement solution differ from the TMC 66. The main differences are described
at the appropriate point in this document.
NOTE
When designing new systems with muting, we recommend using our MLC SPG (Smart Process Gating).
This system will enable you to completely dispense with muting sensors. This will not only save space,
but will also reduce the amount of mounting and installation work required. We would be glad to advise
you in a personal consultation.
NOTE
The supplied software functionality was developed and tested in accordance with the directives appli-
cable for so-called SRASW (Safety-Related Application Software), as defined in ISO 13849-1.
ATTENTION
Before connecting the MSI 420.TMC-03 to the supply voltage, make sure that the device has been
connected in accordance with the supplied wiring plan.
Commissioning may only be performed by a competent person and following the steps given in the
section Electrical connection and commissioning (see chapter 4 "Electrical connection and commis-
sioning").
