4. Typical Applications

5. Operation of wireless sensor

5.1 Add sensors node to Co-ordinator WS433-CL

5.2.1 Add Sensor Node ID automatically

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-ordinator successfully.
• 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 Co-ordinator 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.

5.2.2 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). For more details:

5.2 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

In the memmap file, refer to the Memmap of WS433-RL sheet to configure the sensor's operating parameters accordingly.

The reference memmap addresses are based on the order of the sensors added in the Memmap file above

Below are examples of some typical sensor parameters:

3	16	1	2	Cycle_healthsta	60-7200(s)	600	uint16	Read/Write	Every time interval of Cycle_healthsta,  sensor node will absolutely send data to co-ordinator regardless any condition

6. Installation

6.1 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);

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

ATTENTION:

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.

6.3 Wiring

6.3.1 Power supply connection

• Red: Power Supply
• Black: Ground (GND)

Recommend to use 24VDC power.

The signal cable from the wireless relay should be protected by corrugated hose or the plastic tube, keep the cable avoid high temperature areas.

6.3.2 IO wiring

7. Troubleshooting

No.	Phenomena	Reason	Solutions
1	The status LED of wireless sensor doesn't light up	No power supply Configuration function of the LED is not correct	Check that the battery is empty or not installed correctly Reconfigure the led light function exactly as instructed
2	Wireless sensor not connected to co-ordinator	No power supply The configuration function of the RF data rate is incorrect	Check that the battery is empty or not installed correctly Reconfigure the RF data rate with the button according to the instructions
