INSTALLATION GUIDE
ASAC SOFT STARTER
1 CA UTIO N STATEMENTS
This symbol is used throughout this manual to draw attention to topics of special
importance to the installation and operation of the ASAC Series soft starter.
Caution Statements cannot cover every potential cause of equipment damage but can highlight common
causes of damage. It is therefore the installer’s responsibility to adhere to all instructions in this manual, to
follow good electrical practice and to seek advice before operating this equipment in a manner other than as
detailed in this manual.

Ensure that the ASAC is completely isolated from the power supply before attempting any work on the
unit.

Do not apply incorrect voltages to the control input terminals.

Ensure cables to the control inputs are segregated from AC power and control wiring.

Some electronic contactor coils are not suitable for direct switching with PCB mount relays. Consult the
contactor manufacturer/supplier to see if this is advisable.

Do not connect Power Factor Correction capacitors to the output of ASAC Series soft starters. If static
power factor correction is employed, it must be connected to the supply side of the soft starter.
The examples and diagrams in this manual are included solely for illustrative purposes. Users are cautioned
that the information contained in this manual is subject to change at any time and without prior notice. In no
event will responsibility or liability be accepted for direct or indirect or consequential damages resulting from
the use or application of this equipment.
GROUNDING AND BRANCH CIRCUIT PROTECTION
CAUTION
It is the responsibility of the user or person installing the ASAC to provide
proper grounding and branch circuit protection according to the IEC rules
and local codes.
WARNING - ELECTRICAL SHOCK HAZARD
DANGER
CAUTION
ASAC Series soft starter contains dangerous voltages when connected to line
voltage. Only a competent electrician should carry out the electrical
installation. Improper installation of the motor or the ASAC may cause
equipment failure, serious injury or death. Follow this manual, IEC rules and
local safety codes.
SHORT CIRCUIT
The ASAC is not short circuit proof. Therefore, after severe overload or short
circuit, the operation of the starter should be fully tested.

2.1 O VERVI EW
The ASAC Series comprises two separate ranges, ASAC-0 and ASAC-1. These ranges share common power
and mechanical designs but offer different features sets. These ranges include an internal bypass function that
bypass the soft starter SCRs during run. This allows the ASAC to be installed in a non-ventilated enclosure
without the need for an external bypass contactor.

3.
Control power and mains supply must be removed from the ASAC before
attachment or removal of accessory modules. Failure to do so may result in
equipment damage.
Cut a 92mm 2 hole in the panel and fit the ASAC Remote Operator.

The Remote Operator allows remote operation of the soft starter. Observe all necessary safety precautions
when controlling the soft starter remotely. Alert personnel that machinery may start without Warning.
It is the installer’s responsibility to follow all instructions in this manual and to follow correct electrical practice.
Use all International recognised standard practice for RS485 communications when installing and using this
equipment.

Grounding and Shielding.
Twisted pair data cable with earth shield is recommended. The cable shield should be connected to a GND
device terminal at both ends and one point of the site protective earth.
Termination Resistors.
In long cable runs prone to excessive noise interference, termination resistors should be installed. This
resistance should match the cable impedance (typically 120 Ω). Do not use wire wound resistors.
RS485 Data Cable Connection.
Daisy chain connection is recommended. This is achieved by parallel connections of the data cable at the
actual device terminals.

6.10 Configuration
The ASAC Remote Operator must be configured to operate on the network. When configuring the ASAC
Remote Operator the unit must be powered up with the soft starter in the “ off” mode.
Programming Procedure
1.
Enter program mode by holding down the [ DATA/PROG] pushbutton for 4 seconds. The value of the
first parameter will be displayed.
2.
If required, adjust the parameter value using the [ START/+] and or [ STOP/-] pushbuttons.
3.
Confirm the setting and move to the next parameter by pressing the [ DATA/PROG] pushbutton.
4.
Repeat steps 2 & 3 until all parameters have been set. The ASAC Remote Operator will automatically
exit programming mode when the last parameter value has been set or if the if the keypad is left inactive for
more than 20 seconds.

Calculating the check sum (LRC).
Each command string sent to and from the ASAC Remote Operator includes a check sum. The form used is
the Longitudinal Redundancy Check (LRC) in ASCII hex. This is an 8-bit binary number represented and
transmitted as two ASCII hexadecimal characters.

INSTALLATION GUIDE
ASAC SOFT STARTER
6.13 4-20m A Output
The ASAC Remote Operator has a 4-20 mA analogue output for monitoring motor current.
CAUTION
The 4-20mA output is operational only when the Remote Operator is connected to
ASAC-1 models.
Calibration
The ASAC Remote Operator Motor FLC parameter (Par. 6) must be adjusted to match the
Motor FLC setting in the soft starter. The 4 mA end of the analogue output signal can be calibrated using the
Remote Operator Analogue Output 4 mA Offset parameter (Par. 7). This is set to give a 4 mA output signal
when the motor current is zero.
Refer section 6.10 for the adjustment procedure.
The analogue
output signal spans from 4 mA when the motor current is zero
(ie, soft starter is not running) to 20 mA when the motor current is 125% of the Motor FLC setting in the
Remote Operator parameter 6.
The 4-20 mA analogue output must only be used for motor current monitoring and metering. It is not
designed for process signal control use.

Problem
No control supply voltage.
Four dashes

flashing
A loss of communication has been
detected on the RS485 link to the soft
starter.
nEt on display
A loss of communication has been
detected on the RS485 link to the network.
Incorrect or no
4-20 mA analogue
output signal
The motor cannot be started.
Possible Solution
Check that correct voltage is present at
terminals
1 and 2.
Verify and solve the cause for loss of
communication.
If communication is restored before a soft
starter RS485 Time Out trip, the display
will regain active status and the RS485 LED
will illuminate.
If communication is restored after a soft
starter RS485 Time Out trip, the
display will indicate a trip code.
Use the Reset pushbutton to reset the soft
starter fault.
The Remote Operator has an RS485
Network Time Out Protection setting
(Parameter 3). This mode is entered when
loss of communication is longer than this
time setting. If communication is restored
the system becomes active again.
To clear nEt on the display, press the
DATA/PROG pushbutton momentarily.
Check the correct voltage is present at
terminals
1 and 2.
Check that correct polarity is used at
terminals B10 and B11.
Check that Motor FLC and Analogue
Output 4 mA Offset parameters are set
correctly.
Check that control voltage is connected to
the ASAC, and that terminals 01 and 02
are linked and connected to A1.
