POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
•This equipment is suitable for Pollution Degree 2 and In-
stallation Category II (transient voltage 2500V). Rein-
forced insulation (signal input or output to power input:
300V) and basic insulation (signal input to output: 300V)
are maintained. Prior to installation, check that the insu-
lation class of this unit satisfies the system requirements.
•Altitude up to 2000 meters.
•The equipment must be mounted inside a panel.
•The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE conformance.
•The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conform-
ity.
•Install lightning surge protectors for those wires connect-
ed to remote locations.
■POWER INPUT RATING & OPERATIONAL RANGE
•Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 90 – 264V, 47 – 66 Hz, approx. 2 – 4VA
24V DC rating: 24V ±10%, approx. 0.5W
24 – 240V DC rating: 21.6 – 264V, approx. 1W
■GENERAL PRECAUTIONS
•Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
•Pulling the front part of the unit forcibly may separate
the front housing from the body housing. Touching ex-
posed internal power/input terminals may cause an elec-
tric shock if the unit is powered.
■ENVIRONMENT
•Indoor use.
•When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
•Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
•Environmental temperature must be within -10 to +55°C
(14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
•Be sure that the ventilation slits are not covered with ca-
bles, etc.
■WIRING
•Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
•Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■AND ....
•The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
•With voltage output, do not leave the output terminals
shortcircuited for a long time. The unit is designed to
endure it without breakdown, however, it may shorten ap-
propriate life duration.

■HOW TO SEPARATE THE TERMINAL BLOCKS
When you need to separate the terminal blocks from the
transmitter body for wiring, insert a minus driver between
the terminal block and the housing body, pull up the driver
and pull out the terminal block.
INSTALLATION
■DIN RAIL MOUNTING
Set the unit so that its DIN rail adaptor is at the bottom.
Position the upper hook at the rear side of the unit on the
DIN rail and push in the lower. When removing the unit,
push down the DIN rail adaptor utilizing a minus screw-
driver and pull.

OUTPUT RANGING
The internal DIP switch setting is required to select output
types before setting a precise output range using PC Con-
figurator Software (model: M3SCFG).
For detailed information on the PC configuration, refer to
the M3SCFG users manual.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
If the RTD or its extension wires are broken, the output
goes over 100% (below 0% with downscale protection) due
to the burnout function. Confirm the status indicator
LED pattern and check leadwires in such a case.
4) Output: Check that the load resistance meets the de-
scribed specifications.
STATUS INDICATOR LED
The transmitter is provided with a status indicator LED
which blinks in different patterns indicating various oper-
ating status.
The following figure indicates typical patterns.

MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit using the PC Configurator
Software (model: M3SCFG).
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
