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.
•The equipment must be mounted inside a panel.
•Altitude up to 2000 meters.
•Insert a noise filter for the power source, input and out-
put connected to the unit. COSEL Noise Filter Model
NAC-04-472, TDK Noise Filter Model ZCAT 3035-1330 or
equivalent is recommended.
•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 location.
■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, ≤ 2VA
24V DC rating: 24V ±10%, approx. 0.5W
■GENERAL PRECAUTIONS
•Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
■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 -20 to +55°C
(-4 to +131°F) with relative humidity within 30 to 90%
RH in order to ensure adequate life span and operation.
■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.

I/O RANGING
The DIP switch setting is required to select I/O types before setting a precise output range using PC Configurator Software
(model: M6CFG).
For detailed information on the PC configuration, refer to the M6CFG users manual.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Check DIP switch setting.
3) Power input voltage: Check voltage across the terminal
7–8withamultimeter.
4) Input: Check that the input signal is within 0 – 100% of
the full-scale.
If the thermocouple, RTD, potentiometer 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.
5) 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: M6CFG).
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
M-System to choose appropriate models.
