 NEW SWP Series MC Based Digital Controllers
New SWP series instruments are developed by our expertise of designing and manufacturing of instruments for years, which provided
with newest components and control algorithm. They will present the features of intelligent, standardization, as well as high reliability of
microprocessor-based instruments to our customers.
Based upon many customers are already familiar with our Wide plus instruments, New SWP series will bring up a new way to setting
the internal parameters(including input type, calculation, output parameter, communication protocol, etc.)of instruments. The feature of
instrument with several purposes will provide more flexibility for our customers to deal parameters without depending on the manufacturer.
New SWP series instruments support multiple units networking data communication, different kinds of standard, non-standard serial
bi-direction communication function. Many data communication protocols can be chosen, such as RS-232, RS-422, RS-485, etc. It is
possible for multiple units to communicate to a computer or programmer, baud rate is 300-9600bp/s.
We believe that our customers will obtain more advantages with using New SWP series instruments.

Filtering Coefficient——sampling times, used to stabilize the display value.
Sampling Period——data acquisition time for frequency input. (0.5 second for analog input)
The relationship between PV display value, filtering coefficient and sampling period is shown below.
Example 1:
For frequency input, when filtering coefficient is 2, sampling period 10 seconds, the display value is the average of the samples
in last 20 seconds (10×2).
Example 2:
For analog input, when filtering coefficient is 6, the display value is the average of the samples in last 3 seconds (0.5×6).

 NEW SWP Series MC Based Digital Controllers
★NOTE 3：Display Offset and Proportion:
Formulae for computing Pb1 and KK1:
KK1=preset scale ÷ display scale × KK1(default)
Pb1=lower limit of preset scale-lower limit of display scale×KK1+Pb1(default)
Example：
A device with 4～20mA DC current input range, measuring scale -200～1000Kpa. During calibration the device displayed -202
with 4mA input and 1008 with 20mA input. (Pb1(default)=0，KK1(default)=1)
According to the above formulae：
KKK= preset scale ÷ display scale × KK1(default)
=[1000-（-200）] ÷[（1008）-（-202）] ×1=1200÷1210×1≈0.992
Pb1= lower limit of preset scale-lower limit of display scale × KK1+Pb1(default)
=200-（-202×0.992）+0=0.384
So parameters should be set as Pb1=0.384，KKK1=0.992
★NOTE 4：Cold-junction Compensation Offset and Proportion:
Adjusting Pb2 and KK2 can change the cold-junction compensation value. Formulae for computing Pb2 and KK2 are similar to
those for Pb1 and KK1.
★NOTE 4：Transmit Output Offset and Proportion:
Adjusting Pb3 and KK3 can change the transmit output value. Formulae for computing Pb3 and KK3 are similar to those for Pb1
and KK1.

5. Type of Transmit Output

The device has dual isolated current or voltage outputs, whose types can be defined by users.
★ Output rang can be modified by changing the secondary parameters.(see secondary parameters)
★ Output type can be modified by the jumpers J3(J4) – DC current or DC voltage output.
★ Following is setting of jumpers J3(J4) ( J3(J4) are on the transmit output sub-board）:

Jumpers on D821 serial:

★Note：
1．Output type can be modified by the jumpers J3(J4) –DC current or DC voltage output;
2．DC current output when 1, 2 pins are on, DC voltage output when 2, 3 pins are on;
3．One the dual outputs sub-board J3 is for first output and J4 for second output.

2) How to Wire
Please refer to the “Wiring Diagram”.
3) Wire Connection
① Please keep input signal lines away from any power lines and load lines to avoid interference.
② Instrument’s power line should avoid interference from other power lines, if necessary dedicated filter can be used ( please
identify instrument’s power voltage firstly)
☆ please according its frequency respond to choose the power filter for better performance.
please shorten the pitch of instrument’s power line to reduce the interference.
the power filter must be installed on a well grounded panel, and the connection between its output and instrument’s power
input should be as short as possible.
adding in fuse on the power filter output will reduce its performance.
power source filter instrument’s power input
12

shorten pitch as short as possible power line

please use electrical specification compatible power line ( ground line’s cross section area should be about 1.25～2.0mm
and as short as possible).
③ There is 2～3 output preparation time after power on, so if output is a part of external loop please use time delay relay.
