1 Installation
1.1
DIN rail installation method:
①
The transducer fixed on the side of the card slot and hook
on the mounting rail;
②
Pull the spring pin down;
③
Clip the transducer mount on the mounting rail;
④
Release the spring pin and clip the transmitter on the
mounting rail.
1.2
Screw mounting method:
①
4mm diameter hole in the fixed plate according to the position
of the screw hole shown in Fig. 13;
②
Use the screw
Φ
3.5 to insert into hole and secure it.
2 Products factory has been accurately set according to the
"product standard". Apply power after determine the correct
wiring.
3 The maximum wire diameter of the terminal block is 2mm
(16-26AWG). Remove the 4mm ~ 5mm insulation layer from the
end of the mounting wire and insert it into the terminal block, then
tighten the screw.

Product supply power requires the isolation voltage
≥
2000VAC,
AC ripple <10mV. Multiple transducers can share a common set of
power supplies, but the power circuit can no longer be used to
drive relays and other can produce spikes in the load, in order to
avoid interference signal transmission to the transducer.

T
he transducers output 0-20mA (or 4-20mA), the RL standard is
≤
250
Ω
, and 0-5V voltage output RL standard is
≥
1K
Ω
, can guarantee
the output accuracy and linearity over the entire rated input range.
10Example of product accuracy level verification
1 According to the definition of the transducer terminals to connect
the test circuit.
Fig. 18
2 The test shall be carried out under the following environmental
conditions:
Note:
The voltage output is measured with a voltmeter and the
current output is measured with an Io meter.
2 The test shall be carried out under the following environmental
conditions:

Power preheat 2min;
4 Using high-precision power signal source to input the value of
voltage and current and the corresponding phase,
and record the
display data of calibrator, in order to ensure the veracity of the
accuracy, please enter voltage and current signals more than 20%of
the product rang. The current can be input using the ampere-turn
method.

Example for conversion relationship of output and measured
value: (Power factor products: Vo voltage output, Io current output,
C power factor).
If the output is 0-5V, then C = Vo
÷
5V;
If the output is 4-20mA, then C = (Io-4 mA)
÷
16mA;
If the output is 0-2.5V-5V more than 2.5V, a advance power factor
and inductive load, C = (5V-Vo)
÷
2.5V; When output is less than
