■ 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.
POINTS OF CAUTION
■ NONINCENDIVE APPROVAL OPTION
• This equipment is suitable for use in Class I, Div. 2, Groups
A, B, C and D or Non-Hazardous Locations only.
• WARNING! Before You Remove the Unit from Its Base
Socket or Mount It, Turn Off the Power Supply and Input
Signal for Safety.
• WARNING! – Explosion Hazard –
Substitution of any Components May Impair Suitability for Class I, Div. 2.
• WARNING! – Explosion Hazard –
Do Not Disconnect Equipment Unless Power Has Been
Switched Off or The Area is Known To Be Non-Hazardous.
• The equipment was evaluated for use in the ambient temperature and relative humidity as mentioned in ‘ENVI-
RONMENT’ section.
• The input and output wiring must be in accordance with
Class I, Div. 2 wiring methods and in accordance with the authority having jurisdiction for use in these hazardous locations.
■ 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.
• Be sure that the ventilation slits are not covered with cables, etc.
■ 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.
• With voltage output, do not leave the output terminals shortcircuited for a long time. The unit is designed to endure it without breakdown, however, it may shorten appropriate life duration.

■ CONFORMITY WITH EC DIRECTIVES OR UL
• This equipment is suitable for Pollution Degree 2 and Installation Category II. Reinforced insulation (signal input or output 1 or output 2 to power input: 300V) and basic insulation (signal input to output 1 or output 2: 300V) are 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 noise filters for the power source, input and output connected to the unit. COSEL Model NAC-04-472, TDK
Model ZCAT 3035-1330 or equivalent is recommended.
• 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.

■ 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 (90 – 264V for UL),
47 – 66 Hz, approx. 4 – 6VA
24V DC rating: 24V ±10%, approx. 3W
11 – 27V DC rating: 11 – 27V, approx. 3W
110V DC rating: 85 – 150V (110V ±10% for UL), approx. 3W
■ DIN RAIL MOUNTING
Set the base socket so that its
DIN rail adaptor is at the bottom. Position the upper hook at the rear side of base socket on the DIN rail and push in the lower. When removing the socket, push down the
DIN rail adaptor utilizing a minus screwdriver and pull.
■ WALL MOUNTING
Refer to “EXTERNAL DI-
MENSIONS.”

ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered specifications, therefore you usually do not need any calibration.
For matching the signal to a receiving instrument or in case of regular calibration, adjust the output as explained in the following.
■ HOW TO CALIBRATE THE OUTPUT SIGNAL
Use a signal source and measuring instruments of sufficient accuracy level. Turn the power supply on and warm up for more than 10 minutes.
1) ZERO: Apply 0% input and adjust output to 0%.
2) SPAN: Apply 100% input and adjust output to 100%.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above procedure 1) – 3).
5) Go through the same procedure for the Output 2.
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
10 – 11 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.

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 accuracy described in the data sheet. When the output is out of tolerance, recalibrate the unit according to the “ADJUST-
MENT PROCEDURE” explained earlier.
