PR52: Tripping class
The delay in the event of overload is set via the tripping class (resolution: 1 s). The value set corresponds to
the release time in seconds (for an overcurrent that is precisely 7.2 times greater than the set rated current).
If the overcurrent is more than 7.2 times the rated current, the release time becomes correspondingly
shorter, and is extended if the current is below this value.
Example:
Tripping class = 10 s, rated current = 4.0 A
An overcurrent of 28.8 A (4.0 A x 7.2) results in a release time of 10 s.
PR53: Measuring cycle time
The conversion time of the A/D converter is set through this register directly (with a resolution of 1 ms).
Note
Accuracy of the measurement results
To obtain correct measurement results, a value of less than 30 ms must not be set!
5.2.2 Examples of Register Communication
The numbering of the bytes in the examples corresponds to the display without word alignment.
5.2.2.1 Example 1: reading the firmware version from Register 9
Output Data
Byte 0: Control byte Byte 1: DataOUT1, high byte Byte 2: DataOUT1, low byte
0x89 (1000 1001
bin
) 0xXX 0xXX
Explanation:
• Bit 0.7 set means: Register communication switched on.
• Bit 0.6 not set means: reading the register.
• Bits 0.5 to 0.0 specify the register number 9 with 00 1001
bin
.
• The output data word (byte 1 and byte 2) has no meaning during read access. To change a register,
write the required value into the output word.
Input Data (answer of the bus terminal)
Byte 0: Status byte Byte 1: DataIN1, high byte Byte 2: DataIN1, low byte
0x89 0x33 0x41
Explanation:
• The terminal returns the value of the control byte as a receipt in the status byte.
• The terminal returns the firmware version 0x3341 in the input data word (byte 1 and byte 2). This is to
be interpreted as an ASCII code:
◦ ASCII code 0x33 represents the digit 3
◦ ASCII code 0x41 represents the letter A
The firmware version is thus 3A.
