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 (body + base socket + input resistor) ..... (1)
Input resistor is provided only with current input type.
■ 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.
■ 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.
■ 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 supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.
POINTS OF CAUTION
■ INSULATION CLASS
• This unit is provided with the class of basic insulation.
Prior to installation, check that the insulation class of this unit satisfies the system requirements.
■ CONFORMITY WITH LOW VOLTAGE DIRECTIVE OR UL
• This equipment is suitable for use in a Pollution Degree
2 environment and in Installation Category II, with the maximum operating voltage of 300V.
Basic insulation is maintained between signal input, output and power input. 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 conform to CE/UL requirements. Failure to observe these requirements may invalidate the CE/UL conformance.
■ CONFORMITY WITH EMC DIRECTIVE
• Insert a noise filter for the power source connected to the unit. Densei-Lambda Noise Filter Model MZS-1206-33 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.
■ 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. 6VA
(100 – 240V ±10% for UL)
24V DC rating: 24V ±10%, approx. 3.5W
110V DC rating: 85 – 150V, approx. 3.5W (110V ±10% for UL)

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 that the input signal is within 0 – 100% of the full-scale.
4) Alarm operations: Check the alarm operations referring to the figure below.
5) Output load: Check that the output load is:
Output code 2 and 3: 380V AC/120VA or 125V DC/30W
Output code 5: 380V AC/600VA or 125V DC/150W
Output code 2A, 3A and 5A: 220V DC/30W
For maximum relay life with inductive load, external protection is recommended.

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.

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.
