PW806 Intelligent Digital Controller Introduction and Specification


Wuyue Sensor Co., LTD 
ISO9001:2000 Certified

Company Introduction
Wuyue Sensor Co., Ltd.(WTC) is a high-tech company and maker of sensors and related instruments. WTC majors in researching, designing, making and selling sensors, transmitter and digital instrument. WTC is of the capability to manufacture various kinds of sensors and relative products. Especially with the high temperature melting sensors, PW series products are widely used in plastic, rubber, petrol and chemistry lines. Actually, we are in the lead both at home and abroad. WTC’s products are sold all over our country and exported to Southeast  Asia, and are highly remarked.
PW806 Introduction
PW806 is an intelligent digital pressure controller, which is widely used in measurement and control field. PW806’s appearance is beautiful; key operation is simple; PW806 is capable of resisting interference.
PW806 is adopted with double-row structure with four digit bit in each row to respectively vshow measured value(PV) and set value(SV). Output available is: 4 ~ 20 mA or 0 ~ 10V. Systematic adjustment can automatically finish through keyboard operation, i.e., only pressing “⌒” key to execute the adjustment. PW806 introduces photoelectric technology, watchdog, and special software to resist interference. 
PW806 is generally connected with a high temp. melting sensor, and both of them form an excellent system to measure the pressure and temp. of the melting.  Meanwhile, PW806 can be used to control the operation of motors, which are embedded in other equipments.

Connection between PW806 and sensor
The terminals of connector are as follows: (numeric symbol for five pin cable, alphabetic symbol for six pin cable)
1 (A)……………………….S+  Positive signal 
2 (C)……………………….E+  Positive bridge voltage
3 (B)……………………….S -  Negative signal
4 (D、E)…………………..E -  Negative bridge voltage
5 (F)……………………….C    Calibration

Rear Terminals

1, 2 Open terminals of AL1 relay
2, 3 Close terminals of AL1 relay
4, 5 Open terminals of AL2 relay
5, 6 Close terminals of AL2 relay
7, 8 Input voltage
9 S+ Positive signal from sensor (blue line)
10 E+ Positive voltage for sensor’s power supply (red line)
11 S - Negative signal from sensor (black line)
12 E - Negative voltage for sensor’s power supply (yellow line)
13 C Adjustment (green line)
14 shield
15 + positive signal from thermocouple
16 - negative signal from thermocouple

Power-on and running
After power-on, PW806 does self-check.  At the same time, the above display unit shows the full scale of pressure, and the lower display unit shows the full scale of temperature. After about 2 seconds, the above display unit shows the divided value for pressure, and the lower display unit shows the thermocouple type and divided value for temperature. Finally, PW806 return to working status automatically.
In the working status, the above display unit shows the measured value of pressure, and the lower display unit shows the measured value of temperature.
Modify the inner parameters
In working state, press the “⌒” key for five seconds, and then the inner parameters can be modified. 
Pressing     key,       key and      key to modify the parameter value.
Pressing the “⌒” key stores the modified parameter and transfer to the next parameter.
If user presses “⌒” for five seconds or if user doesn’t press any key for one minute, PW806 will return automatically to working state.
Inner Parameter Table

Pressure Adjustment
Generally, PW806 is corresponded with a sensor, and after our company adjusts them both, user can use them. If PW806 is not corresponded with sensor, user has to adjust both of them. It must be ensured that sensor is loaded zero pressure. 
When PW806 is in working state, user presses CAL key, PW806 starts to adjust automatically. At the same time, user presses “⌒” key till adjustment is finished. PW806 will store the adjusted value. (CAL key and “⌒” must be both pressed till adjustment is finished.)
Note :  before adjustment, user has to open digital locker, that is to say, LCK is set to zero.
