■ INSTRUCTION MANUAL
This manual describes necessary points of caution when you use this product, including installation, connection and basic maintenance procedures.
■ 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
■ CONFORMITY WITH EC DIRECTIVES
• This equipment is suitable for Pollution Degree 2 and Installation Category II. Basic insulation (signal input to output: 300V) is maintained. 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.
• Insert a noise filter for the power source connected to the unit. TDK-Lambda Noise Filter Model MZS-1206-33 or equivalent is recommended.
• The actual installation environments such as panel configurations, connected devices and 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 CE conformity.

■ STATUS LED, PL2
When the PL2 is turned on, identify the device status with
ITEM 02.
REF. STATUS
12 Burnout: Wire breakdown or invalid overrange input.
Check T/C wires, T/C type and temperature range.
13 Input range setting: 0% Setting > 100% Setting
See ITEM 13 / 14.
15 Output range setting: 0% Setting > 100% Setting
See ITEM 15 / 16.
99 Memory error: Initialize all the settings of the unit by operating ITEM 18 and program the unit again.

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 voltage is within 0 – 100% of full-scale.
If the thermocouple or its extension wires are broken, the output goes over 100% (below 0% with downscale) due to the burnout function. Check leadwires in such a case.
4) Output: Check that the load resistance meets the described specifications.

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 accuracy described in the data sheet. When the output is out of tolerance, recalibrate the unit as explained earlier (ITEM
07 and 08).
