1. LED „UH“ lights green?
If
yes
, go to 2.
If
no
, U

has undervoltage or the unit has an internal device failure.
(Internal failures can occur in the case of undervoltage, welded safety output contacts or
seldom because of interference)
==>
switch supply voltage off and on. If the failure still exists in spite of correct auxiliary
supply UH the unit could be defective and has to be sent to manufacturer for test or
repair.
2. 2. LED „ERR“ (red) flashes with code 1?
If
no
, go to 3.
If yes , the unit has detected undervoltage
==> Apply correct auxiliary voltage
3. LED „OUT“ flashes green?
If no , go to 4.
If
yes
, standstill is detected, but the time ts till enabling of the outputs is not elapsed.
==> wait till time ts is finished.
If after 6 s the outputs are not enabled, the measuring input L1-L2-L3 receives intermittent
voltage peaks that are higher then U
an
.
This should normally be indicated by intermittent yellow flashes on the LED).
==> Adjust U
an
to a higher value, clear interference on measuring wires (use screened
cables).
4. 4. LED „OUT“ lights yellow?
If yes , the voltage on the measuring input is higher then the adjusted value U
an
; go to 5.
If
no
, LED is off
Standstill is detected (voltage on measuring input is <U
an
) but the outputs are not enabled
because
a) Feedback circuit X1-X2 is not closed or
b) a simultaneity failure occurred (see failure monitoring) or
c) a previous failure ( broken wire / offset, feedback circuit) is still
stored (terminals x2-x3 are not linked.
The type of failure is indicated by flash code on the red LED „ERR“:
a) flash code 4 (feedback circuit not closed)
b) flash code 5 (simultaneity fault of the measuring signals on L2 L3)
c) code 2, 3 or 4 depending on priority and failure.
==> - close feedback circuit
- Bridge terminals X2-X3 (manual reset)
If now still the simultaneity failure (flash code 5 on LED „ERR“) is indicated it can be
reset by switching the auxiliary supply off and on. The reset also takes place, when
both input signals rise above Uan e.g. when starting the motor. If the simultaneity
failure remains active after start of the motor (e.g. because of short circuit between
L2-L1 or L3-L1) the wiring of the measuring circuit has to be checked according to
the connection example.
If the simultaneity failure occurs often e. g. on slow decease of the motor speed,
the problem can be solved by increasing the tripping value Uan or/and by making
a single phase instead of a 3-phase connection of the measuring circuit to the motor.
