Parameter registers (description)
These registers are used to parameterize the power terminal. They can be read or written by means of register communication.
PR7: Command register
In order to be able to call a command, you first have to enter the user codeword 0x1235 in register R31.
Command 0x7000: Restore Factory Settings
Entering 0x7000 in register R7 restores the delivery state for the following registers:
PR32: 545 (0x0221) | PR40: 0 |
Command 0x8000: Software reset
Entry 0x8000 in register R7 triggers a full software reset of the power terminal. All internal variables are cleared. The internal circuits (output driver) are reinitialized with a software reset.

Risk of injury During a software reset, the contactor connected to the power terminal is released. Ensure that your system state permits this and that hazards for persons or machinery have been ruled out! |
PR8: Terminal description
Register PR8 contains the terminal identifier in hexadecimal coding: KL8001: 0x1F41 (8001dec)
PR9: Firmware version
Register PR9 contains the firmware version of the terminal in hexadecimal coding, e. g. 0x3141 (12609 dec).
PR17, PR18, PR19: Voltage gain compensation
These registers contain the compensation values determined at production, and cannot be changed.
PR20, PR21, PR22: Current gain compensation
These registers contain the compensation values determined at production, and cannot be changed.
PR23: Hall-Sensor sensitivity
The sensitivity of the Hall sensor is adjusted during production, and has a direct effect on the compensation values; it cannot be changed.
PR31: Code word register
- If you write values into the user registers without previously having entered the user code word (0x1235) in the code word register, these values are only stored in the RAM registers, but not in the EPROM registers and are therefore lost if the terminal is restarted.
- If you write values into the user registers and have previously entered the user code word (0x1235) in the code word register, these values are stored in the RAM registers and in the EPROM registers and are therefore retained if the terminal is restarted.
The code word is reset if the terminal is restarted.
PR32: Feature-Register
A variety of KL8001 functions can be activated or enabled by means of the feature register.
Single phase analysis makes it possible to connect three single-phase motors to the power terminal. In this case, the current values for the detection of an overload are evaluated separately. This means that if an error state occurs in one of the three phases L1, L2, or L3, then the corresponding contactor is switched off.
Fast shut off is triggered after about 500 ms if one of the fast shut off functions has been activated and the corresponding error state occurs.

*) The voltages of the three phases are measured with reference to an artificial star point.
PR33, PR39, PR45: Rated current
If you set both rotary switches for setting the rated current at the front of the KL8001 to zero, the values stored in registers PR33, PR39 and PR45 are used for overload control (resolution: 0.01 A, permitted setting range: 0.9 A to 15.0 A). This is useful when:
- different rated currents are required for single-phase evaluation, for example if three different single-phase motors are connected.
- you want to use the extended setting range of 10.0 A to 15.0 A, which cannot be set via the rotary switches.
PR34, PR40, PR46: Switch-on threshold
A switch-on protection phase is maintained before switching on again after the power terminal has switched off the motor because of overload. This time corresponds to the tripping class. In other words, with a tripping class of 50 the motor can only be switched on again after a period of 50 seconds. This time can be shortened by means of this register, which can be useful under some circumstances with large tripping classes.
The value to be entered is calculated in accordance with the following formula:
Example:
Switch-on time = 10 seconds, tripping class = 50 seconds
(1 - 10 sec / 50 sec) x 65535 = 52428
The switch-on threshold to be entered then is 0xCCCC (52428dec).
PR35: L1 overvoltage threshold*
If the mains voltage at L1 exceeds the overvoltage threshold stored (with a resolution of 0.1 V) in register PR35, bit SW.7 will be set in the status word.
*) The voltages of the three phases are measured with reference to an artificial star point.
PR36: L1 undervoltage threshold*
If the mains voltage at L1 falls below the undervoltage threshold stored (with a resolution of 0.1 V) in register PR36, bit SW.4 will be set in the status word.
*) The voltages of the three phases are measured with reference to an artificial star point.
PR37: Overload threshold L1
If the current in phase L1 exceeds the overload threshold stored in register PR37 (with a resolution of 0.01 A), the ESB.0 bit will be set in the extended status byte while the Overload LED will flash at about 5 Hz. If you set the overload threshold in register PR37 below the rated current, the motor can be switched off early in the event of excessive rated load, in order to prevent damage.
PR38: Underload threshold L1
If the current in phase L1 falls below the underload threshold stored in register PR38 (with a resolution of 0.01 A), the ESB.1 bit will be set in the extended status byte while the Overload LED will flash at about 2 Hz. If you set the value in register PR38 below the rated load that has been set, then the motor can be switched off in the event of, for instance, a broken shaft, in order to avoid more serious damage.
PR41: L2 overvoltage threshold*
If the mains voltage at L2 exceeds the overvoltage threshold stored (with a resolution of 0.1 V) in register PR41, bit SW.8 will be set in the status word.
*) The voltages of the three phases are measured with reference to an artificial star point.
PR42: L2 undervoltage threshold*
If the mains voltage at L2 falls below the undervoltage threshold stored (with a resolution of 0.1 V) in register PR42, bit SW.5 will be set in the status word.
*) The voltages of the three phases are measured with reference to an artificial star point.
PR43: Overload threshold L2
If the current in phase L2 exceeds the overload threshold stored in register PR43 (with a resolution of 0.01 A), the ESB.0 bit will be set in the extended status byte while the Overload LED will flash at about 5 Hz. If you set the overload threshold in register PR43 below the rated current, the motor can be switched off early in the event of excessive rated load, in order to prevent damage.
PR44: Underload threshold L2
If the current in phase L2 falls below the underload threshold stored in register PR44 (with a resolution of 0.01 A), the ESB.1 bit will be set in the extended status byte while the Overload LED will flash at about 2 Hz. If you set the value in register PR44 below the rated load that has been set, then the motor can be switched off in the event of, for instance, a broken shaft, in order to avoid more serious damage.
PR47: L3 overvoltage threshold*
If the mains voltage at L3 exceeds the overvoltage threshold stored (with a resolution of 0.1 V) in register PR47, bit SW.9 will be set in the status word.
*) The voltages of the three phases are measured with reference to an artificial star point.
PR48: L3 undervoltage threshold*
If the mains voltage at L3 falls below the undervoltage threshold stored (with a resolution of 0.1 V) in register PR48, bit SW.6 will be set in the status word.
*) The voltages of the three phases are measured with reference to an artificial star point.
PR49: Overload threshold L3
If the current in phase L3 exceeds the overload threshold stored in register PR49 (with a resolution of 0.01 A), the ESB.0 bit will be set in the extended status byte while the Overload LED will flash at about 5 Hz. If you set the overload threshold in register PR49 below the rated current, the motor can be switched off early in the event of excessive rated load, in order to prevent damage.
PR50: Underload threshold L3
If the current in phase L3 falls below the underload threshold stored in register PR50 (with a resolution of 0.01 A), the ESB.1 bit will be set in the extended status byte while the Overload LED will flash at about 2 Hz. If you set the value in register PR50 below the rated load that has been set, then the motor can be switched off in the event of, for instance, a broken shaft, in order to avoid more serious damage.
PR51: Maximum permissible current difference
If the current difference between two phases exceeds the value stored in register PR51 (with a resolution of 0.01 A) then bit SW.0 is set in the status word.
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).
 | Accuracy of the measurement results To obtain correct measurement results, a value of less than 30 ms must not be set! |
