TROUBLE SHOOTING

Upon fault

±

motor stops,

Fault

LED lights and Fault Relay operates. The LCD shows TRIP: and fault

description. (for example: TRIP: UNDER CURRENT).

Fault Massage

Cause and trouble shooting

TOO MANY
STARTS

Trips the starter if number of starts, during START PERIOD exceeds the preset
number.

Wait until motor and starter cool down

±

according to START INHIBIT setting.

For more information on adjusting START PERIOD and START INHIBIT refer to
section

7.6.4 on page 36.

LONG START
TIME

Trips the starter if output voltage does not reach nominal at the present MAX. START
TIME.

Check FLA, FLC, and MAX START TIME settings. Increase INITIAL VOLTAGE,
CURRENT LIMIT & MAX. START TIME or decrease ACCELERATION TIME as
necessary.
For more information on FLC & FLA refer to section

7.6.3 on page 32 (MAIN

PARAMETERS).
For more information on adjusting START PARAMATERS refer to section

7.6.4 on

page 36.

O/C

±

SHEAR

PIN

Trips the starter when:
Instantaneously when current exceeds 8.5 x Starter FLC. (not programmable)
During starting when current exceed 8.5 x Motor FLA. (not programmable)
During running when current exceeds 100-850%.(programmable value)
O/C Shear-Pin has a programmable delay of 0-5 seconds where the starter detects
the fault and does not trip before time delay has elapsed (delay is override when
current reaches 8.5 x Starter FLC).

Check that motor is not installed or Jammed.
Check FLA, FLC settings.
Check motor and cable connections.

(MAIN PARAMETERS).

CAUTION

is no more than 500V !!

O/C or WRONG
CON.

Trips the soft RVS-DXM when connected Inside Delta and Wrong connection or if
over current is detected by the RVS-DXM.

Verify that the motor is not stalled or shorted and check cables and wiring.
Verify that motor and RVS-DXM are connected exactly as shown in section

4.5.3.2

page 14.
If circuitry is 100% confirmed it is possible to start when WIDER SETTINGS are
ENABLED. Refer to

section

7.6.7 page 43

. If a fault occurs again consult the factory.

The operator is advised to try operating one time only. Note that it is useless to try
starting in this mode more than once.

OVERLOAD

Trips the starter when current exceed the OVERLOAD TRIP level and thermal
register has filled up.

Check FLA, FLC and Overload settings, check motor current, wait 15 minutes to let
motor and starter cool down before restarting.
For more information on FLC, FLA & OVERLOAD settings refer to section

7.6.3 on

page 32 (MAIN PARAMETERS).
