POINTS OF CAUTION

■POWER INPUT RATING & OPERATIONAL RANGE

• Locate the power input rating marked on the product and

conﬁrm its operational range as indicated below:

24V DC rating: 24V ±10%, approx. 60mA

■GENERAL PRECAUTIONS

• Before you remove the unit 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 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 sup-

plied, however, a warm up for 10 minutes is required for

satisfying complete performance described in the data

sheet.

WIRING INSTRUCTIONS

■SCREW TERMINAL

Torque: 0.8 N·m

CHECKING

1) Terminal wiring: Check that all cables are correctly con-

nected according to the connection diagram.

2) Power input voltage: Check voltage supplied to the rack

(model: 18KBXx). For the DC power source, be sure that

the ripple level is within 10% p-p.

3) Input: Check that the input signal is within 0 – 100% of

the full-scale.

4) Output: Check that the load resistance meets the de-

scribed speciﬁcations.

ADJUSTMENT PROCEDURE

This unit is calibrated at the factory to meet the ordered

speciﬁcations, therefore you usually do not need any cali-

bration, unless you need to match the signal to a receiving

instrument or conduct regular calibration.

Zero and span are adjusted with using the Programming

Unit (model: PU-2x).

Refer to the Operation Manual for Model PU-2x for expla-

nations how to use the programmer.

■WARNING ON USE OF THE PROGRAMMING UNIT

• Be sure to disconnect the Programming Unit before you

turn on/off power supply to the unit.

• The output signal is held when the Programming Unit is

connected. You need to disconnect when conﬁrming cur-

rent output values.

■HOW TO CALIBRATE THE OUTPUT 1

Use a signal source and measuring instruments of sufﬁcient

accuracy level. Turn the power supply on and warm up for

more than 10 minutes.

There is no need of adjusting the Output 2.

• Fine Output Calibration

Using the Programming Unit (ITEM 19, 20)

ITEM 19 is for Zero, and ITEM 20 is for Span.

1) Turn the unit into Program mode (ITEM 01).

2) Apply simulated 0% input. Increase/decrease values

(default: 0%) at ITEM 19 until the output signal is cali-

brated to actual 0%.

3) Apply simulated 100% input. Increase/decrease value

(default: 100%) at ITEM 20 until the output signal is cali-

brated to actual 100%.

4) Apply simulated 0% input again and check 0% output.

5) When 0% value is changed, repeat the above procedure

2) – 4).

The 0% value may be shifted when the output span is

greater than the input span (gain > 1).

P: Modiﬁable only when the MAINTENANCE SWITCH is in the “PRG” mode.

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 accu-

racy described in the data sheet. When the output is out of

tolerance, recalibrate the unit according to the “ADJUST-

MENT PROCEDURE” explained earlier.

LIGHTNING SURGE PROTECTION

M-System offers a series of lightning surge protector for

protection against induced lightning surges. Please contact
