• 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.
• 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.
• Install lightning surge protectors for those wires connected to remote locations.
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and confirm its operational range as indicated below:
100 – 240V and 85 – 264V AC rating: 85 – 264V
(90 – 264V for UL), 47 – 66 Hz, approx. 3 – 5VA
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
■ 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 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.

INSTALLATION
Loosen the fixing screw at the front of the unit in order to separate the body from the base socket.
■ 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.

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
13 – 14 with a multimeter.
3) Input: Check voltage across the terminal 1 – 4 with a sensitive voltmeter.
(With 20°C or 68°F, approx. 220mV with Pt 100, approx.
110mV with Pt 50Ω.)
If RTD 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.
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for protection against induced lightning surges. Please contact
M-System to choose appropriate models.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered specifications, therefore you usually do not need any calibration.
The output signal can be finely adjusted to match it to a receiving instrument, or to compensate input wire resistance when the unit is combined with a zenor barrier. Follow the regular calibration procedure explained below:
■ 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).
M2RS
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.
