■INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
The unit is programmable using the PC Configurator Soft-
ware. For detailed information on the PC configuration,

figurator Software is downloadable at M-System’s web site:
http://www.m-system.co.jp.
POINTS OF CAUTION
■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: 85 – 264V, 47 – 66 Hz, approx. 5 – 7VA
24V DC rating: 24V ±10%, approx. 3W
■GENERAL PRECAUTIONS
• To protect very delicate components contained inside
the unit against damage from static electricity, wear a
grounded wrist strap when handling them. If you do not
have one, touch both of your hands to a safely grounded
object or to a metal object.
• Ensure that the power supply and input signal are
switched off before you plug in or remove the unit.
• Before you remove the unit from its base socket 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 -5 to +55°C
(23 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 20 minutes is required for
satisfying complete performance described in the data
sheet.
• With voltage output, do not leave the output terminals
shortcircuited for an extended time period. The unit is
designed to endure it without breakdown, however, it may
shorten appropriate life duration.

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: W2CFG).
For detailed information on the PC configuration, refer to
the W2CFG 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
10 – 11 with a multimeter.
4) Input: Check that the input signal is within 0 – 100% of
the full-scale.
If the thermocouple or its extension wires are broken, the
output goes over 100% (below 0% with downscale) due to
burnout function. Confirm the status indicator LED pat-
tern and check leadwires in such a case.
5) Output: Check that the load resistance meets the de-
scribed specifications.
6) LED: Confirm that the LEDs indicate the normal operat-
ing mode.

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: W2CFG).
LIGHTNING SURGE PROTECTION
