• Motor with a power range of up to 3 kW/400 V AC can be operated with the electronic compact starter. A frequency of
2 Hz - 2 starts per second, 120 starts per minute, 7200 stars per hour is realizable.
• An AC-51 utilization category up to 9 A with a frequency of 2 Hz is also possible.
Please note that frequent switching means high starting currents for the motor. This leads to temperature increases in the
motor windings. As the electronic compact starter calculates a model of the thermal load on the motor dependent on the
operating time and current load, tripping can occur.
After tripping, the motor memory module is discharged after two minutes. You must wait for this cooling time to elapse
before the manual reset can be done. An automatic reset takes place after 20 minutes.
Frequency converters, single- phase motors, DC-motors:
Usage of the HF range in combination with a frequency converter is not admissible.
Single-phase motors are only allowed to be switched with the HF9-R. All other variants provide internal measuring
technology. The internal measuring technology evaluates this combination as an error and the device indicates a fault.
Please use a frequency of 50/60 Hz.

For switching non-inductive loads it is recommended to use a HF9-R-24VDC. This range offers no overload protection and no
monitoring functionality.
Thresholds
The threshold values describe the value where the electronic compact starter switches the motor on or off.
• Threshold level 'high' is 19.2 V…30 V
• Threshold level 'low' is -3 V…9.6 V
As can be seenn figure 9, the electronic compact starter recognizes different control input voltages. All values between 19.2
V and 30 V leads to switching on the motor. For values between 9.6 V and -3 V the motor will be switched off.
This means that the control voltage, applied in terminal ‘ON’, must be
• > 19.2 V to switch the motor on
• < 9.6 V to switch the motor off
