*If temperature of the device reaches the over temperature warning threshold the overheat flag will be set. If
the device is in over temperature protection state, then it will be set overheat and over current flags together.
Examples
1) For the current value parameter, 0300:
To request value, send the following command:
"J0300" in text or "4a 30 33 30 30 0d" in hex.
Answer will be:
"4b 30 33 30 30 20 30 33 45 38 0d" in hex, "K0300 03E8" in text, 03E8h > 1000 in dec > 10.00 A.
To set new value, for example, 8.00 A (0320 in hex), send the following command:
"P0300 0320" in text or "50 30 33 30 30 20 30 33 32 30 0d" in hex.
2) For the state of the device, 0700:
To request value, send the following command:
"J0700" in text or "4a 30 37 30 30 0d" in hex.
Answer will be:
"4b 30 37 30 30 20 30 30 44 35 0d" in hex, "K0700 00D5" in text, 00D5h > 11010101 in bin >
Device is powered on, stopped, internal current set, internal enable, denied external NTC
Interlock, denied Interlock.
To set new state, for example, allow Interlock, send the following command:
"P0700 1000" in text, "50 30 37 30 30 20 31 30 30 30 0d" in hex.
3) Errors:
If a command with the wrong parameter number was sent, answer will be "K0000 0000"
("4b 30 30 30 30 20 30 30 30 30 0d").
If a command with the wrong format was sent, answer will be an error "E0001"
("45 30 30 30 31 0d").
