operating the Programming Unit.

In MONITOR mode (Maintenance Switch = 0), the unit is in normal

operation: repeating measuring, calculating and renewing the out-

put signal. In this status, the status indicator LED is flashing in

constant intervals of approx. 3 Hz (ON : OFF = 1 : 1). You can

monitorinput%,output%andoperatingstatus,variousparameters,

etc. on the Programming Unit.

The PROGRAM mode (Maintenance Switch = 1) is used when you

change various parameters concerning measuring, calculation and

output. Inthisstatus,thestatusindicatorLEDisflashinginconstant

intervalsofapprox.1.5Hz(ON:OFF=1:1). Inthetransitionperiod

fromMONITORtoPROGRAMmode,theLEDflashesapprox.in1.5

Hz but in different intervals (ON : OFF = 1 : 3), which indicates that

the unit is still processing the last cycle of measuring.

In PROGRAM mode, the unit stops measuring and renewing the

outputsignal. Theoutputisheld,butyoucanoutputaspecificvalue

for simulation and testing.

Whenalltheprogramchangeisover,be suretoreturn thetransmit-

ter to MONITOR mode. The modification will be lost if you turn off

power supply to the transmitter without doing this.

EXPLANATIONS OF TERMS & FUNCTIONS

■ BASIC OPERATION

After the power is turned on, the JAPD accesses and checks the

data stored in its non-volatile memory. When there is no abnormal-

ity, it starts measuring.

The input signal, processed through the analog input circuit and

convertedintofrequency,iscomparedwiththepreset0%(zero)and

100%(span)inputvalues(as calibrated at the factory)todetermine

the input value. Then the signal is compared with the preset 0%

(zero)and100%(span)outputvaluesandconverted proportionally

into an frequency output.

Whenthecomparedresultisoutofthenormaloperationalrange,the

output is limited to a value -15% or +15% of the full-scale.

The input is sampled according to the sampling time (default 200

ms), and the output is renewed every this cycle.

■ OPERATION MODE AND MAINTENANCE SWITCH

There are two operation modes: MONITOR mode and PROGRAM

mode.

Whenthepowersupply is turned on, theunitstartsup in MONITOR

mode. However, you can switch from one mode to another by

■ STATUS INDICATOR LED

TheCPUstatusisindicatedbydifferentblinkingpatternsofthefront

indicator LED. 1 pattern cycle is divided in 16 ON or OFF periods,

each of which lasts for 320 millisec.

In the figure to the right, ●●means that the light is OFF, while ●

meansthatit isON. TheON-OFF pattern changesfromthe leftend

to the right in 320 millisec. duration.

There are more of these patterns which are not shown here,

however, when the last one shown in the figure to the right or some

other pattern is indicated, contact M-System.

The anomaly report is available also on the display of the Program-

ming Unit. Refer to its manual for detailed information.

HARDWARE SETTING & CALIBRATION

■ SENSITIVITY ADJUSTMENT

You can change the output voltage amplitude with the Output

VoltageAdjustmentwithin5–24V. Howevertheoutputcloseto24V

may be affected by line voltage variations.

• How to Change the Sensitivity

A voltmeter of class 0.5 or better accuracy is required.

1) Connect the voltmeter in parallel to the terminal 1 – 2 of base

socket.

2) Turn the Output Voltage Adjustment until the meter indicates a

desired value.

SOFTWARE SETTING

You can program various parameters with Programming Unit,

model: PU-2❑. For detailed explanations, please refer to the

Operation Manual for Model PU-2❑(EM-9255), Section B.

In the Programming Unit, specifying GROUP No. and ITEM No.

(each 2 digits) determines which item is to be changed.

POINTS OF CAUTION

■ GENERAL

• Before you remove the unit from its base socket or mount it, turn

off the power supply and input signal for safety.

■ ENVIRONMENT

•Whenheavydustormetalparticlesarepresentintheair,installthe

unit inside proper housing and ventilate it.

•Donotinstalltheunitwhereitissubjectedtocontinuousvibration.

Do not apply physical impact to the unit.

• Environmental temperature must be within -5 to +60°C (23 to

140°F) in order to ensure adequate life span and operation.

■ WIRING

•Donotinstallcables(powersupply,inputandoutput)closetonoise

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.
