Protections
Overheating threshold
This command sets the threshold temperature in Celsius at which the overheating protection activates.
As long as the measured temperature is above the threshold the relay will be OFF and you will not be able to turn it ON.
Byte index | Bit index | Hex value β Meaning |
0 | - | 1E β The command code. |
1 | - | Threshold temperature in Celsius. Default value 0x5A=90Β°C. |
Example downlink: 0x1E3C β Set the threshold temperature to 0x3C=60Β°C.
The allowed threshold temperature range is 30...100Β°C (1.0Β°C resolution).
Overvoltage threshold
Set the threshold voltage, which when exceeded will turn OFF the relay.
As long as the measured voltage is above the threshold the relay will be OFF and you will not be able to turn it ON.
Byte index | Bit index | Hex value β Meaning |
0 | - | 20 β The command code. |
1 | - | Voltage data, bits - [15:8]. |
2 | - | Voltage data, bits - [7:0]. Default value 0x113=275V. |
Example command: 0x200118 β Set the threshold voltage to 0x0118=280V.
The allowed threshold voltage range is 80...300V (1V resolution).
Overcurrent threshold
Set the threshold current, which when exceeded will turn OFF the relay.
As the measured current is above the threshold the relay will be OFF.
Byte index | Bit index | Hex value β Meaning |
0 | - | 22 β The command code. |
1 | - | Threshold current in amperes. Default value 0x10=16A. |
Example command: 0x220B β Set the threshold current the 0x0B=11A.
The allowed threshold current range is 1...16A (1A resolution).
Overpower threshold
Set the threshold power, which when exceeded will turn OFF the relay.
As the measured power is above the threshold the relay will be OFF.
Byte index | Bit index | Hex value β Meaning |
0 | - | 24 β The command code. |
1 | - | Power data, bits - [15:8]. |
2 | - | Power data, bits - [7:0]. Default value 0x0E10=3680W. |
Example command: 0x2407D0 β Set the threshold power to 0x07D0=2000W.
The allowed threshold power range is 100...3680W (1W resolution).
Overheating event
The command is sent together with the keepalive of the device. The keepalive data in the example below is omitted for clarity.
Byte index | Bit index | Received response |
0 | - | 60 β The command code. |
1 | - | Number of overheating events. |
2 | - | Temperature in Celsius. |
Example command: 0x60
Example command: 0x6053C β when we extract the value of the command code, we get the number of overheating events 0x05=5 and a temperature of 0x3C=60Β°C.
Overvoltage event
The command is sent together with the keepalive of the device. The keepalive data in the example below is omitted for clarity.
Byte index | Bit index | Received response |
0 | - | 61 β The command code. |
1 | - | Number of overcurrent events. |
2 | - | Voltage data, bits - [15:8]. |
3 | - | Voltage data, bits - [7:0]. |
Example command: 0x61
Example command: 0x61030180 β when we extract the value of the command code, we get the number of overvoltage events 0x03=3 and a voltage of 0x0180=280V.
Overcurrent event
The command is sent together with the keepalive of the device. The keepalive data in the example below is omitted for clarity.
Byte index | Bit index | Received response |
0 | - | 62 β The command code. |
1 | - | Number of overcurrent events. |
2 | - | Current data, bits - [15:8]. |
3 | - | Current data, bits - [7:0]. |
Example command: 0x62
Example command: 0x62031952 β when we extract the value of the command code, we get the number of overcurrent events 0x03=3 and a current of 0x1952=6482mA.
Overpower event
The command is sent together with the keepalive of the device. The keepalive data in the example below is omitted for clarity.
Byte index | Bit index | Received response |
0 | - | 63 β The command code. |
1 | - | Number of overcurrent events. |
2 | - | Power data, bits - [15:8]. |
3 | - | Power data, bits - [7:0]. |
Example command: 0x63
Example command: 0x630307D0 β when we extract the value of the command code, we get the number of overpower events 0x03=3 and a power of 0x07D0=2000W.
