2/12 Remote Operator
2 General Description
The Remote Operator allows remote operation of the soft starter, and offers the following functionality:
• Operational control (Start, Stop, Reset, Quick Stop)
• Starter status monitoring (Ready, Starting, Running, Stopping, Tripped)
• Performance monitoring (motor current, motor temperature)
• Trip code display
• 4-20 mA analog output (motor current)
• Optional RS485 network connection
1
The Remote Operator can act as a gateway device for connection to an RS485 serial communications
network, allowing remote control of a motor using Modbus RTU or standard AP ASCII communications protocol.
For further information on Modbus control of a soft starter, please refer to the Modbus Module Instructions.
NOTE
In order to use the Remote Operator with ASAC starters, a Remote Operator Module or Modbus
Module must also be installed.

Remote Operator
This section describes how to install the Remote Operator for basic control and monitoring of a soft starter. The
Remote Operator is pre-configured to control a soft starter once control supply power is applied to both devices.
For basic operation, no parameter adjustments are required on the Remote Operator or the soft starter.
In order to use the Remote Operator's 4-20 mA analog output to monitor motor current, follow the instructions in
the section 4-20 mA Analog Output on page 9.
3.1 Mounting
The Remote Operator is rated IP54 or NEMA 12 1 when mounted correctly in accordance with these
instructions. It is intended for use on the flat surface of a panel, with all external wiring connected from behind
the panel.
The Remote Operator is supplied with a mounting bracket and four fasteners. The built-in gasket seal
guarantees protection from outside the panel.
Select the panel location of the Remote Operator. The required panel cutout is 92 mm x 92 mm. Place the
Remote Operator through the cutout and locate the mounting bracket at the rear of the panel onto the four
studs. Use the four fasteners to tighten the mounting bracket up to the rear of the panel.

For use on a flat surface of a NEMA 1 or NEMA 12 enclosure.
3.2 Electrical Connections
The Remote Operator requires a minimum of three electrical connections - the external power supply, the
chassis earth and the RS485 Starter port. All external wiring, except the chassis earth (M4 stud provided), is
connected to spring operated clamp connector terminals with a maximum wire size of 2.5 mm
are required.
3.2.1 Grounding and Shielding
Twisted pair data cable with earth shield is recommended. The cable shield should be connected to the GND
device terminal at both ends and one point of the site protective earth.
3.2.2 Termination Resistors
In long cable runs prone to excessive noise interference, termination resistors should be installed between the
data lines at both ends of the RS-485 cable. This resistance should match the cable impedance (typically
120 Ω). Do not use wire wound resistors.
3.2.3 RS-485 Data Cable Connection
Daisy chain connection is recommended. This is achieved by parallel connections of the data cable at the
actual device terminals.

5.1 Operation
The Remote Operator performs all soft starter functions except programming of the soft starter. The Remote
Operator can only be used to program its own parameters.

Simultaneously pressing the STOP and RESET buttons initiates a quick stop, which immediately removes
voltage from the motor, ignoring any soft stop time set on the starter.
NOTE
Motor current and motor temperature information is only available from ASAC-1 starters. If connected
to a ASAC-0 open loop soft starter, the display will show 2222 instead of motor current and 1.11
instead of motor temperature.
5.2 Trip Codes
If the soft starter trips, the CODE and TRIP LEDs illuminate and the relevant trip code is reported on the
Remote Operator display.

8/12 Remote Operator
6 4-20 mA Analog Output
6.1 Overview
The Remote Operator has a 4-20 mA analog output for monitoring motor current. The 4-20 mA output is
available on terminals B10, B11.
The analog output signal spans from 4 mA when the motor current is zero (when the 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).
NOTE
The 4-20 mA output only operates when the Remote Operator is connected to ASAC-1 soft starters.
6.2 Calibration
The Remote Operator Motor FLC parameter (parameter 6) must be adjusted to match the Motor FLC setting in
the soft starter.
The lower end of the analog output signal can be calibrated using the Remote Operator Analog Output 4 mA
Offset parameter (parameter 7). This is set to give a 4 mA output signal when the motor current is zero.
The 4-20 mA analog output has an accuracy of ±10%. It is not designed for process signal control and should
only be used for motor current monitoring and metering.
NOTE
The analog output uses only one Motor FLC setting. This function is not suitable for applications
6.3 Programming
using two motor parameter sets.
When the 4-20 mA output is being used, the Remote Operator's Motor FLC and Analog Output 4 mA Offset
parameters (Parameters 6 and 7) must be set appropriately (see Calibration). Programming can only be
carried out while the soft starter is not running.
6.3.1 Programming Procedure
1. To enter Programming Mode, hold down the Data/Prog pushbutton for four seconds. The default value of
the first parameter will be displayed.
2. Use the Data/Prog pushbutton to advance to the next parameter.
3. Use the Stop and Reset pushbuttons to adjust parameter values.
Programming Mode closes when the Data/Prog pushbutton is pressed after parameter 9.
NOTE
There is a 20 second timeout when the Remote Operator is in Programming Mode. Programming
Mode will automatically close if no input is registered for 20 seconds. Any changes already made
will be saved.
