31 ELECTRONIC COMPACT STARTER | MANUAL
Signaling for ROL-types
The following table shows the LED codes for ROL- and ROLE-device diagnostics. An equivalent table can be found in the
package insert.
• HF0.6-ROL-24VDC
• HF2.4-ROL-24VDC
• HF9-ROL-24VDC
Operation status
The electronic compact starter uses LEDs to indicate status messages for operation, fault and test:
Status Description PWR ERR L R Error acknow-
ledgment
LED colors on HMI (human machine interface) Green Red Yellow
OFF Supply voltage not present OFF OFF OFF OFF -
Ready to operate Supply voltage present ON OFF OFF OFF -
Drive switched on Reverse running (L) ON OFF ON OFF
Forward running (R) ON OFF OFF ON
Internal error Internal device error –
device replacement required
ON ON OFF OFF Not possible
External error in the
controller or the I/O
devices (maintenance
requirement, NE44)
Motor protection function:
The motor current is higher than the nominal motor current
specification (e.g. Class 10A): Cooling time is running
(20 min.)
• An error occurred with left rotation (reverse running) ON Flashes ON OFF Automatic
1)
• An error occurred with right rotation (forward running) ON Flashes OFF ON Automatic
1)
After 2 minutes, the 'L' or 'R' flashes: a manual reset is
possible
• An error occurred with left rotation (reverse running) ON Flashes Flashes OFF Manual
• An error occurred with right rotation (forward running) ON Flashes OFF Flashes Manual
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, also in automatic operation.
ON Flashes Flashes Flashes Manual
Symmetry: The two motor currents deviate from each other
by more than 33%.
ON Flashes OFF OFF Manual
Blocking: The max. measurable motor current is exceeded
for more than 2 sec..
• An error occurred with left rotation (reverse running) OFF Flashes Flashes OFF Manual
• An error occurred with right rotation (forward running) ON Flashes OFF Flashes Manual
Message (power path
remains switched on)
Message with pending control signal:
- Two or more phases are missing
- No motor connected
- Motor current in at least two phases >2 sec. below the
minimum current value that can be set
• A message occurred during reverse running. Flashes Flashes ON OFF Automatic
2)
• A message occurred during forward running. Flashes Flashes OFF ON Automatic
2)
