TSLM - M601 Operational & Install Manual
Introduction
System Options
This manual describes the installation and operation of the Turbine Start Limit & Monitor (TSLM)
from VR Avionics when used with a Walter/GE M601 engine. The TSLM is a unit (black box) which
can function standalone or with other units (black boxes) from VR Avionics as shown below. This
manual is dedicated to the TSLM, so when planning to install further units the user must also
include the manuals of these other units. For example, should you plan to use one or more VRX
multi-function displays, you need to read the VRX-M601 Operational & Installation manual.
Retrofit to existing systems
The TSLM unit can be easily retrofitted to an already
existing aircraft system. Since it is remote mount, it will have
little to no impact on your current instrument panel if start
control and limiting is all you require. You can however
choose to add a VRX multi-function display (shown here) for
the added monitoring it provides, in which case you need to
make a little space for this on your panel.
TSLM versions
A few versions of the TSLM have been produced over the years. Later versions have remained
backward compatible with earlier ones by retaining the connector and pin-outs for the most part.
The following table lists the differences other than normal general performance improvements of
the various versions as referenced by their serial numbers:
Serial number range Differences
3001 - 4100 First Generation
5001 - 6200 Oil-temperature measurement added
7001 and later New more compact enclosure
No serial port connector
Units with serial numbers 5001 and up are handled in this manual.
