§１．Summary
This indicator has two signal input channels from the distortion gauge type transducer andperforms sampling 100 times per second of incoming signals and two channels aresynchronized.
Also this indicator has various functions such as comparator function, hold function, and zero
tracking function, etc.
Other than the measurement of each channel of CH-A and CH-B, the measurement of addition/ subtraction, as CH-A+CH-B or CH-A−CH-B, is carried out simultaneously.
This unit has 8 comparators which is able to output 8 comparison results through open
collectors of transistors.
As an option, 3 analog output corresponding to the measured value of each channel CH-A,
CH-B and calculated value TOTAL converted from digital data can be output.
The power supplied voltage is the wide range of voltage AC100 to 240V.

§２．Installation and connection method of the unit
２－１)

Installation environment of this unit

1)

Operation temperature range of this unit is 0℃ to +40℃.
Please install this unit in a place not exposed to direct sunlight and condensation.

2)

The power supply is AC100V to 240V.
Recommend to use a constant-voltage transformer if power supply is not stable.

3)

This unit is designed to fix by a panel-mount. Please make use of the attached metal
fittings to fix it on.

4)

Please confirm the cable specification before wiring this unit.

5)

A shield line of each cable should be ground to either one of this unit or each connected
equipment.

２－２) To obtain stable measurement
When a sensor of strain gauge (i.e., Load Cell, Pressure gauge) is amplified by an amplifier oris connected to an indicator, the value may fluctuate or may not be stable.
Control Unit
(PLC, etc.)

SensorIndicator, Amplifier(DLS-5026B, etc.)( Fig. 1 )This is because of difference of an electric potential between a sensor part and an amplifier /indicator part. It is induced from electric potential of commercial power (AC100V/AC200V).

( Fig. 2 )The most effective way to improve stability is to use a cable to connect an Earth termina l of anamplifier / indicator to a case or chassis of sensor, like Fig 2.
If it is difficult to find an Earth terminal of sensor side, loose a bolt of metal case of sensor andconnect the cable. Please make the electric potential be same as possible.
In case that a sensor and amplifier / indicator have installed separately, stability improves when
an Earth terminal of indicator / amplifier and a metal case of sensor connect to the nearest earthof each. But if they are apart far from each other, it may not bring a good result due to different
electric potential of the earth. However, in such a case, stability improves if connecting a cableas Fig 2.

This function is a serial interface dedicated for a TOYO’s peripheral equipment. If TOYO’s
CV-3010(serial to BCD converter) is connected to this interface, the measured value of thisunit can be output as parallel BCD signal. Also an external indicator of TOYO can beconnected to this interface.
This interface is isolated from an inner circuit and connected to an external equipment
through 4 to 20mA current loop, thus less affected from noise and a cable can be extended
up to 100m.
CV-3010 can be connected through RS-232C, but if the distance between this unit andCV-3010 is more than 15m, current loop interface should be used.
There is no function setting of this interface. Use a two -core cable and connect from output‘S.OUT’ of this unit to input ‘C/L’ of external equipment. Two -core can be connectedwhichever as there is no polarity of them.
There is no use of a shielded cable in short distance, but wire apart from a power line or adrive motor line with noise.

This unit is supplied voltage with AC100 to 240V.
2) Please check that wires are connected to the terminal base properly and firmly.
９－２) Precautions at the time of calibration.
1) Error occurs at the time of zero calibration.
・In case of exceeding the range of zero calibration.
To perform zero point calibration, Load Cell output with no load should be in the range of−2.8～+2.8mV/V. Please call us if it is out of the range of ±2.8mV/V, when using Load Cell
whose rated output is more than 3.3mV/V.
2) Error occurs at the time of span calibration, or display value is not correct as set in spancalibration.
・In case of a sensor output being higher.
This unit cannot measure in a system that the sum of initial tare value and measured value
exceed 3.3mV/V. Please contact us when the rating output of the sensor is more than
3.3mV/V.
・In case of input level of span calibration being lower.
This unit cannot calibrate span when span amount of output of Load Cell is lower thanvalue set at [ CH−x CAL / 2 CAL 1 ]. Increase minimum scale at [ 6 FCAL SETTING / 3
MIN.DIV ] to make resolution rougher or use an appropriate Load Cell.
3) Fluctuation of indication
・In case of span amount against resolution being not enough.
The input sensitivity of this unit is 0.25μV/digit and indication resolution is 1/20,000 at
1.0mV/V input. If the resolution is more than this, fluctuation of indication becomesbigger. In this case, please increase minimum scale at [ 6 FCAL SETTING / 3 MIN.DIV ] until
not to be noticeable of fluctuation.
９－３) Countermeasure when abnormal display is indicated
In case of the measured value blinking when not overloaded. Causes are considered asfollows.
① Disconnection of sensor cable② Sensor failure
Please confirm input signal from a sensor at [ 11 TEST MODE / 9 SENSOR CHECK ] in TestMode.
９－４) Judgement whether this unit has malfunction
1) Please confirm whether sensor excitation voltage is correct. Please disconnect sensor
from this unit and check the voltage by a tester between #1(+EXC) and #2( -EXC) of
terminal, #6−#7, #11−#12 or #16−#17 are stable at 5V±0.5V. If it is not stable, thisunit should have malfunction.
2) Make electrical short between #3(+SIG) and #4(-SIG) of terminal, #8−#9, #13−#14,#18−#19 ( make input voltage 0V ). Check input voltage at [ 11 TEST MODE / 9 SENSORCHECK ]. Please confirm whether it is stable at around 0.0000 mV/V. If it is not stable, thisunit should have malfunction. If it is stable, please check a sensor or sensor cable.

3) Digital I/O check
Please perform I/O check at [ 11 TEST MODE / 5 EXT.IN CHEK or 6 EXT.OUT CHECK ] in TestMode.
９－５) Checking Sensor ( Load Cell )Good or bad rough judgement can be done by measuring input/output resistance andinsulation resistance because the Load Cell is structured by a bridge circuit.
(Please make sure to power OFF this unit first and disconnect Load Cell before checking
resistance)
1) Fault judging method by resistance of Load Cell.
Check bridge resistance of Load Cell by a tester, and conf irm whether input/output
resistance are correct.
2) Fault judging method by insulation resistance of Load Cell.
Measure insulation resistance between shield line and other with voltage less than 50V. I f
the insulation resistance has more than 1000MΩ, insulation of Load Cell is no problem.
