Softstarters are electronic devices designed to enable 1-phase or
3-phase induction motors to start smoothly. The GF 9016 slowly ramps up
the current on two phases, therefore allowing the motor torque to build up
slowly. This reduces the mechanical stress on the machine and prevents
damage to conveyed material.
When the motor is up to full speed the power semiconductors in
GF 9016 are bridged to prevent internal power losses and heat build up. In
addition GF 9016 allows a softstop function prolonging the stop time of the
motor, preventing high counter torques from abruptly stopping the motor.
•Motors with gear, belt or chain drive
•Fans, pumps, conveyor systems, compresseors
•Packaging machines, door drives
•Start current limiting on 3 phase motors

Troubleshooting
In case of a fault, please proceed as follows:
Fault 1:
Electronics supply or motor too small (see technical data minimum motor
load). Send device to the producer to have it checked.
Fault 2:
Check the frequency of starts and the starting current and also observe
the max. ambient temperature. Give the device and/or the motor enough
time between starts to cool down. The heat dissipation can be improved
by forced cooling, e.g., by means of a fan mounted unterneath the device
or by using a motor with a separately driven fan.
Fault 3:
Defect in the internal control electronics. Send device to the producer to
have it checked.
Fault 4/5:
Mains supply is interrupted.Motor lead interrupted, power semiconductor(s)
defective, motor defective. Check motor and wiring. Send device to the
producer to have it inspected.
Fault 6/7:
Mains supply is interrupted. Power semiconductors do not trigger. Motor
rating is too small. Check as to whether the motor is suitable for the device
rating. Send device to the producer to have it checked.
Fault 8:
Mains or motor wiring is interrupted. Power semiconductor(s) defective.
Check wiring. Send device to producer to have it inspected
Motor load must always be connected as continuous operation of the
softstart with no load may cause overheating of the motor and softstart.
It is recommended that the softstart is protected by superfast semiconductor
fuses rated as per the current rating of the softstart or motor. However,
standard line and motor protection is acceptable, but for high starting
frequencies motor winding temperature monitoring is recommended.
Resetting of faults
The fault message can be reset by disconnecting and reconnecting the
supply voltage.
!
Warning:
At any rate, the cause of the fault has to be identified and remedied by
trained and qualified personnel. Only then must the device be put into
operation again.
Notes
!
Attention:
Please pay attention and consider for the operation of IE3 motors while
dimensioning of softstarters the resulting higher starting currents.
For the use of IE3 motors we highly recommend to dimension and design
the needed softstarters one size higher.

Connect conact to X1, X2 and select softstart (close contact) or softstop
(open contact). As option the unit can also be started by an external
control voltage of DC 10-24 V. This has to be connected to terminals X2,
X3, X4 connecting means starting up,disconnection stopping. On terminal
X3 a kickstart function can be activated. This is useful on motors that have
a high starting load as e.g. mills, breakers, conveyors. Kickstart takes 0.5
sec at fully switched thyristors.
X5, X6: Error at phase failure, frequency variation, thyristor failure,
overtemperature of the unit, disconnected motor. Reset by
switching the unit off and on.
X7, X8: Softstart finished, semiconductors bridged.
Set potentiometer "Ustart" to minimum (fully anti-clockwise).
Set potentiometer "t " to maximum (fully clockwise).
Set potentiometer "t " to mid position.
Start the motor and turn potentiometer "Ustart" up until the motor starts to
turn without excessive humming.
Stop the motor and restart.
Adjust potentiometer "t " to give the desired ramp time.
Stop and restart the motor.
Adjust potentiometer "t " to give the desired deceleration time.
Stop and restart the motor, readjusting the potentiometers until the desi-
red starting/stopping characteristics are achieved.
- Attention: If the ramp-up time is adjusted to short, the internal bridging
contact closes before the motor is on full speed.
This may damage the bridging contactor or bridging relay.

Standard Type
Ordering Example
Control Input
- Never clear a fault when the device is switched on
- Attention: This device can be started by potential-free contact, while
connected directly to the mains without contactor (see
application example). Please note, that even if the motor is
at rest, it is not physically separated from the mains.
Because of this the motor must be disconnected from the
mains via the corresponding manual motor starter.
- The user must ensure that the device and the necessary components
are mounted and connected according to the locally applicable
regulations and technical standards.
- Adjustments may only be carried out by qualified specialist staff and
the applicable safety rules must be observed.
