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.
This equipment is for use in general industrial environments, therefore may not be suitable for applications which require higher level of safety (e.g. safety or accident prevention systems)or of reliability (e.g. vehicle control or combustion control systems).
For safety, installation and maintenance of this equipment must be conducted by qualified personnel.
■ PACKAGE INCLUDES:
Signal conditioner
(body + base socket + CJC sensor) .................................(1)
■ MODEL NO.
Confirm that the model number described on the product is 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.
■ SYMBOLS USED ON THE PRODUCT AND IN THIS MANUAL
The symbol indicated on the equipment, means that the user must refer to the related parts in the manual for safe operation of the equipment. It is essential to read the instructions wherever the symbol appears in the manual.
WARNING: is reserved for conditions and actions that can cause serious or fatal injury.
CAUTION : is reserved for conditions and actions that can cause injury or instrument damage.
WARNING
■ INSULATION CLASS
Basic insulation (Signal input or output to Power input: 300
V) is maintained.
If insulation failure may result in equipment, hazardous voltage (maximum 240 V) may result to signal input and then electric shock may cause.
Prior to installation, prepare supplemental insulation
(equivalent basic insulation) between signal input and external circuits.
CAUTION
■ REGARDING SAFETY
If equipment is not used in a manner not specified by M-
System, the protection provided by the equipment may be impaired.
■ CONFORMITY WITH LOW VOLTAGE DIRECTIVE OR UL
• This equipment is suitable for use in a Pollution Degree
2 environment and in Installation Category II (transient voltage 2500 V).
• 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 conform to EU/UL requirements. Failure to observe these requirements may invalidate the EU/UL conformance.
■ CONFORMITY WITH EMC DIRECTIVE
• Insert a noise filter for the power source connected to the unit. TDK-Lambda Noise Filter Model RSNA-2006 or equivalent is recommended.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affect 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 conformity.
■ SIGNAL INPUT
This terminal is used for signal input.
Do not connect or measure to the circuits including transient voltage 2500 V.
Refer to “INPUT SPECIFICATIONS” in detail.
■ OUTPUT TERMINAL
Never use the output terminal under any load that exceeds the rated values. Otherwise it will impair prescribed performance and cause burning of the equipment itself.
■ WIRING
• For wiring connection, refer to “TERMINAL CONNEC-
TIONS” and wire correctly. Fire, electric shock and failure cause if wire are incorrectly connected.
• Wire using vinyl insulated power cable that meet input voltage and load current for equipment and screw by an adequate torque.
Loose screws may abnormally generate heat and fire may cause. (Proper tightening torque [N·m] : 0.98 – 1.18)
• 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.

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:
■ AC Power
M2: 100 – 240 V AC, 50 – 60 Hz, maximum 6 VA
(85 – 264 V AC, 47 – 66 Hz)
■ DC Power
R: 24 V DC (24 V ±10%), maximum 3.5 W
P: 110 V DC (85 – 150 V), maximum 3.5 W
■ GENERAL PRECAUTIONS
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.
■ AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.
• Never use the internal relay under any load that exceeds the rated contact values including the switching capacities (contact voltage and contact current).
Otherwise it will impair prescribed performance (insulation failure, contact welding, contact failure) and cause burning of the Relay itself.

TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the connection diagram on top of the unit.
Attach the CJC sensor together with input wiring to the input terminals. The CJC sensor is not interchangeable.
Check that its serial number is the same as that of the unit.

MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 10 minutes.
• H (HH) Setpoint
Increase the input signal from a value lower than the setpoint and check that the relay trips at the H (or HH) setpoint within the setpoint accuracy described in the data sheet.
• L (LL) Setpoint
Decrease the input signal from a value higher than the setpoint and check that the relay trips at the L (or LL) setpoint within the setpoint accuracy described in the data sheet.
When the setpoints are shifted, please contact M-System’s
Sales Office or representatives.
CHECKING
1 ) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2 ) Power input voltage: Check voltage across the terminal 7 – 8 with a multimeter.
3 ) Input: Check across the terminals 5 – 6 with a sensitive voltmeter to show a normal emf voltage value.
If the thermocouple or its extension wires are broken, the PV display indicates the upper range temperature limit and blinks (the lower range limit with downscale) due to burnout function. 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 rating road is: 240
V AC / 120 VA or 30 V DC / 30 W (240 V AC / 600 VA or 30 V DC / 150 W for dual alarm, Output Code 5) at the maximum. For maximum relay life with inductive load, external protection is recommended.
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-System.
