Signaling

The electronic compact starter provides visual confirmation of the operating status with four LEDs. The functions of the
LEDs follow NAMUR NE 44 recommendations.

Signaling for DOL-types
The following table shows the LED codes for
• HF0.6-DOL-24VDC
• HF2.4-DOL-24VDC
• HF9-DOL-24VDC
Operation Status
The electronic compact starter uses the LEDs to indicate the status messages for operation, fault and test:
Status Description
LED colors on HMI (human machine interface)
OFF Supply voltage not present
Ready to operate Supply voltage present
Drive switched on Forward running motor
Internal error Internal device error –
device replacement required
External error in the Motor protection function: The motor current is higher than
controller or I/O the nominal motor current specification (e.g. Class 10A):
devices (maintenance Cooling time is running (20 min.)
requirement)
After two min., 'ON' flashes: a manual reset is possible
Error restoring the system state: Checksum error. The
thermal memory of the motor protection function is set to
the maximum value. The error must be manually
acknowledged.
Symmetry: The two motor currents deviate from each other
by more than 33%.
Blocking: The max. measurable motor current is exceeded
for more than two sec..
Message (power path Message with pending control signal:
remains switched on) - Two or more phases are missing
- No motor connected
- Motor current in at least two phases > two sec. minimum
current value that can be set
