Signaling for ROLE-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-ROLE-24VDC

Function Test
General function test when U
S
is applied: After the control supply voltage U
S
is applied, all the LEDs light up once. The device
performs a diagnosis of the functions when the load is being switched on or when it is switched off.
Motor overload protection safety function test:
A skilled worker, well acquainted with the relevant standards, can conduct a 'motor overload protection' safety function test.
For this test, the load must be activated and the current flow in a conductor interrupted (e.g. by removing L1 or L3 phase).
The Electronic Compact Starter then switches off the load within 1.5-2 sec.. The LED for right rotation (forward running)
goes out and the ‘ERR’-LED and the reply output are set.
