This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
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.
■ POWER INPUT RATING & OPERATIONAL RANGE
•Locate the power input rating marked on the product and
confirm its operational range as indicated below:
Rating 100 – 240V AC: 85 – 264V, 47 – 66 Hz, approx. 6VA
Rating 24V DC: 24V ±10%, approx. 3.5W
Rating 110V DC: 85 – 150V, approx. 3.5W
■ UNPLUGGING THE UNIT
•Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.
MODEL
MXT
■ 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.

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.

CHECKING
■ BURNOUT
[E.G.] Downscale burnout
1) Turn the unit into Program Mode.
2) Burnout Protection
Choose ITEM 12 – DATA 0.
3) Turn the unit into Monitor Mode.
■ RESET ALL SETTINGS
Returning the unit into the factory-default settings.
1) Turn the unit into Reset Mode.
Set ITEM 01 – DATA 3 to turn the unit into Reset
Mode.
2) Call up the Reset menu.
Choose ITEM 18 – DATA 1. (Press DATA UP key.)
3) Resetting Enable
Double-click DATA DOWN key. DATA 0 is displayed after the initialization is complete.
4) Turn the unit into Monitor Mode.
If necessary, go to Moving Average and other adjustments.
Set the unit to Monitor Mode other than for programming.
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.
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 as explained earlier (ITEM
07 and 08).
