Operation Principle

Process of measurement

When the sensor sampling time interval is reached, for example 2 minutes, the node will wake up and switch ON the power supply to supply the energy to external sensor to start the measurement. Depends on the type and characteristic of external sensor, the sensor will take a certain time to finish the measurement.

For example: the measurement time is 200mS, after this time, the node will read the value of sensor using I2C, node will switch OFF power supply to external sensor to save energy.

Once reading the sensor value, the raw data is X, it can be scaled to any engineering value by the following formula:

Y = aX + b

Where

X: the raw value from sensor
Y: the calculated value for parameter 1’s value or parameter 2’s value
a: constant (default value is 1)
b: constant (default value is 0)

So, if there is no user setting for a and b ==> Y = X
The Y value will be compared with Lo and Hi threshold.

For example 1: We need to calibrate the mA sensor at 4-20mA. When putting the sensor at 4mA and 20mA, we will have:

The raw X1 ADC value measured at 4 mA (Y1 value) CO2 is 605, and the value of X2 ADC value at 20 mA (Y2 value) is 3005. Then:

Use the offline configuration tool to configure sensor. Write in the sensor the parametersa 1 and b1.

Status bytes of sensor Node

Hi-Byte is error code

Error code	Description
0	No error
1	Just exchange the sensor module but node has not been reset ==> please take

out the battery for 20s then install it again to reset node to recognize the new sensor module
2| Error, sensor port M12F shorted to GND
3| Error, sensor port M12F shorted to Vcc
4| Error, sensor port M12F shorted each other

Lo-Byte is sensor type

Error code	Description
0	No error
1	Just exchange the sensor module but node has not been reset ==> please take

out the battery for 20s then install it again to reset node to recognize the new sensor module
2| Error, sensor port M12F shorted to GND
3| Error, sensor port M12F shorted to Vcc
4| Error, sensor port M12F shorted each other

Info: Refer to Section 5.4 for more details.

Add sensors node to Co-ordinator WS433-CL

Add Sensor Node ID automatically

Daviteq-WS433-MA-Wireless-Current-Input-fig-9

Step 1: After supplying power the Co-ordinator via M12 connector, the Node ID must be registered within the first 5 minutes, up to 40 WS.
Step 2: Bring the wireless sensor closer to the Co-ordinator’s antenna then take off the wireless sensor battery, wait for 5s then insert the battery again. If:

Buzzer plays 1 peep sound, LED blink 1 time, that means registering Node ID on Co-ordinators uccessfully.
Buzzer plays 2 peep sounds, LED blink 2 times, that this Node ID is already registered.

If you do not hear the “Peep” sound, please disconnect the power the co- ordinator, wait a few minute and try again.

Node id added in this way will be written to the smallest node_id_n address which is = 0.

Set Rssi_threshold (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL), default -25): The case if Coordinator is on high position and need to add node sensor. We set the sensor as close as possible and set the Rssi_threshold to -80, -90 or -100 to increase the sensitivity to allow WS433-CL-04 can add sensors at a longer distance. After that, perform 2 steps of adding sensors and then reset Rssi_threshold = -25.

Enb_auto_add_sensors configuration (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL)): In case you do not want to turn off the power WS433-CL, you can set Enb_auto_add_sensors = 1, this way we have 5 minutes to add nodes (add up to 40 nodes) . After 5 minutes Enb_auto_add_sensors will automatically = 0.

Add sensor node into WS433-CL-04 (1) through intermediate WS433-CL-04 (2) and Modbus

In case the sensor need to be added to WS433-CL-04 (1) has been installed in a high position, the sensor cannot be brought close to WS433-CL-04 (1).

Button Function

Open the cover of sensor then use the push button to set the data transfer speed for the first 30 seconds when the battery is first installed, after 30 seconds the push button function does not work.
Press and hold the button for 2 seconds => LED blinks once => Release the button to set Data rate RF 50kbps
Press and hold the button for 5 seconds => LED blinks twice => Release the button to set Data rate RF 625bps
Press and hold the button for 10 seconds => LED blinks 3 times => Release the button to reset RF parameters (frequency, RF output power, data rate), if held for more than 30 seconds then the button function does not work.

Reset default WS433

Frequency: 433.92 MHz
RF transmit power: 15 dBm
RF data rate: 50 kbps

Configuration

First, you need to prepare

Daviteq-WS433-MA-Wireless-Current-Input-fig-10

Num of Node will indicate the number of nodes managed by WS433-CL.
Every time a node is added, the Num of Node will increase by 1.
Every time a node is deleted, the Num of Node is reduced by 1.
Writing Num of Node = 0 will delete all 40 node ids to 0.
If you want to delete a node id, then write it = 0 with theW rite function is 16 and the Read function is 3.

Step 1: Connect Antenna, RS485 – configuration cable and power supply co- ordinator

Installation

Mounting bracket installation

Locate the place where the wireless sensor is mounted, from that locate the position to mount the bracket;
Placing the wireless module on bracket and secure it by 02 x M2 screws (supplied in accessory bag)

Note: The bracket can be mounted on the wireless module in both direction, upward or downward

The mounting bracket is made from hard metallic material. The following steps are for mounting this bracket;

Installation location

Wireless sensor utilize the ultra-low power 433Mhz RF signal to transmit/receive data with Wireless co-ordinator. To maximize the distance of transmission, the ideal condition is Line-of-sight (LOS) between the Wireless sensor and Gateway. In real life, there may be no LOS condition. However, the two modules still communicate each other, but the distance will be reduced significantly. The bracket will be fixed on the wall or material with a flat surface with double-sided 3M tape (included in the accessory bag in a carton box) or 2 x M4 screws (supplied by the customer);

Info: When using 3M double sided tape, please install the sensor at a height of 2 meters or less.

ATTENTION

Daviteq-WS433-MA-Wireless-Current-Input-fig-18

DO NOT install the Wireless sensor or its antenna inside a completed metallic box or housing, because the RF signal can not pass through the metallic wall. The housing is made from Non-metallic materials like plastic, glass, wood, leather, concrete, cement…is acceptable.

IO Wiring

Warning

DO NOT CONNECT AN EXTERNAL POWER SUPPLY TO THE PWR + WIRE OF THE WIRELESS SENSOR !!!
SUPPLYING AN EXTERNAL POWER SUPPLY TO THE SENSOR’S PWR + LINE CAN MAKE SERIOUS DAMAGE !!!

CASE 1 : WORK WITH LOOP POWERED SENSOR

Daviteq-WS433-MA-Wireless-Current-Input-fig-20

CASE 2: WORK WITH NON – LOOP POWERED SENSOR

Warning: The signal cable from sensor should be protected by corrugated hose or the Φ16 plastic tube, keep the cable avoid high temperature areas.

Battery installation

Steps for battery installation:

Step 1: Using Philips screw driver to unscrew M2 screw at the side of housing.
Step 2: Pull out the cover then insert the AA 1.5VDC battery, please take note the poles of the battery.
- ATTENTION: Because of O-ring, it requires to have much pulling force at the beginning, therefore please do it carefully to avoid the damage of circuit board which is very thin (1.00mm);
- REVERSED POLARITY OF BATTERIES IN 10 SECONDS CAN DAMAGE THE SENSOR CIRCUIT!
Step 3: Insert the top plastic housing and locking by M2 screw
