Register description

These registers are used for the parameterization of the power measurement terminal and exist for each
channel. They can be read or written by means of register communication.
R0: Overflow register for energy consumption
If the register for the energy consumption (read via process data index [} 47] 0x4) overflows, this overflow
register is incremented. 32 bits are thus available for storing the energy consumption. The overflow register
for the energy consumption must be read via the register communication.
R5: Password change register
You can change the password for the KL3403 (default: 1235
the energy consumption.
The password can be changed as follows:
1. Enter the old password (default: 1235
2. Enter the new password in the password change register (R5).
3. Repeat the new password in the command register (R7).
The new password is now active without resetting the terminal!
R7: Command register
Command 0x1004: Deleting the energy consumption (user password must be set)
Write the value 0x1004 into the command register, in order to delete the energy consumption stored in the
process data (process data index [} 47] 0x4) and the overflow register for the energy consumption (R0
[} 52]).
Command 0x1005: delete maximum current
Write the value 0x1005 into the command register, in order to clear the maximum current stored in the
process data (process data index [} 47] 0x5).
Command 0x1006: clear maximum voltage
Write the value 0x1006 into the command register, in order to clear the maximum voltage stored in the
process data (process data index [} 47] 0x6).
Command 0x1007: clear maximum active power
Write the value 0x1007 into the command register, in order to clear the maximum active power stored in the
process data (process data index [} 47] 0x7).
Command 0x1009: clear minimum current
Write the value 0x1009 into the command register, in order to clear the minimum current stored in the
process data (process data index [} 47] 0x9).
Command 0x100A: clear minimum voltage
Write the value 0x100A into the command register, in order to clear the minimum voltage stored in the
process data (process data index [} 47] 0xA).
