POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• The equipment must be mounted inside a panel.
• 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 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:
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.

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: 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) Confirm that the wire insulation tubes are not caught in
the clamp.
3) Check DIP switch setting.
4) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
5) Input: Check that the input signal is within 0 – 100% of
the full-scale.
If the potentiometer or its extension wires are broken,
the output goes over 100% (below 0% with downscale
protection) due to the burnout function. Confirm the sta-
tus indicator LED pattern and check leadwires in such a
case.
6) 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
We offer a series of lightning surge protector for protec-
tion against induced lightning surges. Please contact us to
choose appropriate models.
