Teds Function - KYOWA WGI-400A Instruction Manual

3-8 TEDS FUNCTION

TEDS function of the WGI-400A is a function that reads excitation voltage, rated output, and rated capacity
from transducer data with TEDS function (Transducer Data Electronic Sheet) built-in and automatically
registers sensitivity and decimal point position.
1) TEDS Function with Initial Value
Set sensors in no-load state as same as in sensitivity registering calibration. Activate the TEDS function and
digital Zero is automatically activated to display '0' (No-load Zero). In addition, sensitivity registering
calibration is automatically activated and a decimal point position is set.
TEDS function is activated by key operation (Press the SHIFT key while pressing the TEDS key) or from
the RS interface when the power is turned ON. However, in the default value, automatically conducting the
TEDS function with the power ON is prohibited. See 'F-20.'
Reference: When replacing a faulty sensor with that of the same type, set only the rated output of 'F-21'
to '0: Allow' and set rated capacity and excitation voltage to '1: Prohibit.' At this time,
coefficient internally used is only changed and the rated capacity (indicated value) and
decimal point position are not changed. If all the settings of the 'F-21'are set to '0: Allow,'
indicated value and decimal point position are calculated and obtained.
2) Excitation Voltage
Excitation voltage is set to a high voltage and less than sensor recommended excitation voltage.
<Example> When the recommended excitation voltage is 3 volt, it is set to 2 volt.
3) Calculating calibration coefficient
Calibration coefficient is registered as a value obtained by dividing the sensor rated capacity by the rated
output.
4) Digital Zero
Digital Zero activated in TEDS operation is considered as Zero in calibration function and shall be set as a
standard Zero point.
5) Indicated Value
Indicated value is shown in 4 digits including rated capacity and a decimal point.

6) Connecting Multiple TEDS Sensors
When connecting multiple TEDS sensors (Maximum 4 TEDS) in parallel, calculate the combined rated
capacity and rated output as follows.
Rated capacity (Combined):
Rated output (Combined):
= 5.000
= 50.00
= 500.0
= 5000
[kN] = 50.00
[kN] = 500.0
Total sum of rated capacity of sensors
Average of rated output of sensors (Value obtained by dividing sensor
total sums by the number of TEDS sensors.)
