INSTRUCTION MANUAL
BEFORE USE ....
Thank you for choosing M-System. Before use, please check
contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact M-System’s Sales Office or representatives.
■ PACKAGE INCLUDES:
Signal conditioner......................................................... (1)
■ MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
The M6DXAR is programmable using the PC Configurator
Software. For detailed information on the PC configuration,
refer to the M6CFG users manual. The M6CFG PC Con-
figurator Software is downloadable at M-System’s web site:
http://www.m-system.co.jp
POINTS OF CAUTION
■ CONFORMITY WITH EC DIRECTIVES
• The relay output circuit is suitable for use in Pollution De-
gree 2 environment in Overvoltage Category II with the
maximum operating voltage 250V.
Prior to installation, check that the insulation 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.
■ 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 ven-
tilation.
• 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 (power supply, input and output)
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 sat-
isfying complete performance described in the data sheet.

M6DXAR
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 indica-
tor LED pattern and check leadwires in such a case.
4) Alarm operations: Check the alarm operations referring
to the figure below.
5) Output load: Check that the output load is 250V AC/
500VA or 125V DC/60W. For maximum relay life with
inductive load, external protection is recommended.
LED FUNCTIONS
■ STATUS INDICATOR LED
The M6DXAR is provided with a status indicator LED
which flashes in different patterns indicating various op-
erating status.
The following figure indicates typical patterns.
■ ALARM MONITOR LED
The M6DXAR is provided with an alarm monitor LED
which flashes in different patterns indicating various alarm
status.
The following figure indicates typical patterns.
MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 10 minutes.
• H Setpoint
Increase the input signal from a value lower than the set-
point and check that the relay trips at the H setpoint within
the setpoint accuracy described in the data sheet.
• L Setpoint
Decrease the input signal from a value higher than the set-
point and check that the relay trips at the L setpoint within
the setpoint accuracy described in the data sheet.
When the setpoints are shifted, recalibrate the unit using
the PC Configurator Software (model: M6CFG).
LIGHTNING SURGE PROTECTION
In order to protect the unit from lightning surges entering
through power supply cables, use of appropriate lightning
surge protectors are recommended. Please contact M-Sys-
tem.
