  • Page 2: Important User Information

    Important User Information 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 internationally recognised standard practice for RS-485 communications when installing and using this equipment.

  • Page 3: General Description

    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) •...

  • Page 4: Installation

    Installation 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.
  • Page 5 3.2.4 Remote Operator RS-485 Network Connection Specifications Input impedance: 12 kΩ Common mode voltage range: - 7 V to + 12 V Input sensitivity: ± 200 mV Minimum differential output voltage: 1.5 V (with max loading of 54 Ω) Soft starter connections The Remote Operator connects to ASAC soft starters via a Remote Operator Module or Modbus Module.
  • Page 6 3.3.2 Configuration The DIP switches on the Modbus Module must be set as follows: DIP Switch A DIP Switch B Protocol = AP ASCII Address = 20 Baud Rate = 9600 Parity = No parity Timeout = No timeout The Remote Operator internal parameters must be set as follows: Parameter 1 (RS485 network baud rate) = set to match Modbus master Parameter 2 (RS485 network address) = unique number between 1 ~ 99 Parameter 3 (RS485 network timeout) = set as required...

  • Page 8: Operation

    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. 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.

  • Page 9: 4-20 Ma Analog Output

    4-20 mA Analog Output 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).
  • Page 10 6.3.2 Programmable Parameters The Remote Operator offers the following programmable parameters: Parameters 1 to 5 only apply when the Remote Operator is being used as a Modbus or AP ASCII network gateway. Parameter Description Default Adjustable Range Number Setting RS485 network 2 = 2400 baud baud rate (9600 baud)
