KL8001 Power terminal - Functional description

Rotary switches for adjusting the rated current

You can set the motor's rated current manually using the two rotary switches on the power terminal. The upper rotary switch operates in 1 A steps, while the lower switch provides 0.1 A steps. You can thus set values between 0.9 A and 9.9 A. The value set then applies to all three phases.

If you set the two rotary switches to zero, you must specify the rated motor current using the three parameter registers PR33, PR39 and PR45. You can then:

set the rated current separately for each phase, if three different single-phase motors are connected, for example.
use the extended setting range of 10.0 A to 15.0 A, which cannot be set via the rotary switches.

LEDs

The power terminal has 4 LEDs for status display to enable rapid diagnosis. The possible states are listed in the following table.

LED	State	Description
on (motor)	on	Motor is running, either to the right or left
on (motor)	off	Motor is switched off, or overload protection has triggered
overload (motor)	on	Motor has been switched off due to overload
	flashes (2 Hz)	Power has fallen below minimum load threshold
	flashes (5 Hz)	Overload threshold has been exceeded
	off	Nominal operation (load neither below minimum and or above maximum), or motor is switched off
run (fieldbus)	on	Communication with the terminal bus is taking place without errors
run (fieldbus)	off	No communication with the terminal bus (watchdog timer has triggered after 100 ms)
stop (fieldbus)	on	No communication with the terminal bus
	flashes	Error code and error argument are indicated as flashing code
	off	Communication with the terminal bus is taking place without errors

Flashing Code

If there is a fieldbus error, the stop LED indicates a flashing code that describes the fault more accurately:

The LED flickers for about 2 seconds before starting the error output. After a clearly visible pause, the error code is indicated through slow flashing, and the error argument is then indicated after a further pause. The following table allows you to determine the error more precisely with the aid of these two items of information.

Code	Argument	Description	Solution
1	0	No rated current set: both the two rotary switches and the register PR33 are zero (single-phase analysis not active) or at least one of registers PR33, PR39 or PR45 is zero (single-phase analysis is active)	Use the rotary switches to set a rated current, or enter values for the rated current in registers PR33, PR39 and PR45.
2	n	Communication with the nth ADC is faulty	Contact your supplier.
3	n	Communication with the n^th Hall sensor is faulty

Description

Solution

No rated current set: both the two rotary switches and

the register PR33 are zero (single-phase analysis not active) or
at least one of registers PR33, PR39 or PR45 is zero (single-phase analysis is active)

Use the rotary switches to set a rated current, or
enter values for the rated current in registers PR33, PR39 and PR45.

Communication with the nth ADC is faulty

Contact your supplier.

Communication with the n^th Hall sensor is faulty

	Changing the terminal registers To ensure that the new values are applied to the measuring unit after the terminal registers have been changed, you have to perform: a power-off reset (switch the terminal off and back on again) or a software reset (via the command register)!
