Introduction

Overview

Eaton’s S811+ soft starter is an electronic, self-contained, panel- or enclosure-mounted motor soft-starting device. It is intended to provide three-phase induction motors with a smooth start, both mechanically and electrically. The S811+ soft starters utilize six SCRs connected in a full wave power bridge. Varying the SCR conduction period controls the voltage applied to the motor. This in turn controls the torque developed by the motor. After the motor reaches speed, internal contacts are closed to bypass the SCRs.

The S811+ has built-in communications capabilities via a Communications Port. The Communications Port is a screw terminal block that is utilized for Modbus® communications   or communication to an Eaton HMI. Communications   adapters are available for other protocols. Please consult   Eaton for availability.

The S811+ soft starter utilizes a Digital Interface Module   (DIM) that allows the user to configure the device, read   and write system parameters, and evaluate fault codes   for troubleshooting.

The DIM includes an easy-to-read display and keypad to scroll through the parameters. The Digital Interface Module allows the user to modify control parameters, enable or disable protections, set system variances from Fault TRIP to Fault WARNING, set communication variables, monitor system parameters such as line voltages and currents and access   the fault queue.

The S811+ is designed to fulfill the industrial service requirements for applications such as chillers, pumps, and machine tools that require less than 100% of the motor’s   rated starting torque for worst-case starting condition.

The S811+ meets all relevant specifications set forth by   UL® 508, CSA® 22.2-14-1995 IEC® 60947-4-2, and   CCC GB14048.

RF susceptibility statement

It is possible, in the presence of strong RF fields, and at specific RF frequencies, that this device could indicate an increase of up to 40 V in the measured line voltages in the 370 to 420 kHz frequency range; or an increase of up to 10% (FLA) of the measured load currents in the 111 MHz to 132 MHz and   152 MHz to 155 MHz frequency range. Should this occur, and affect the functions of the required motor protection settings, refer to the troubleshooting section of this manual.

Shipping
S811+Soft Starters are to be shipped in packaging that adequately protects the unit.
S811+ units installed in an OEM system as a mounted assembly in a cabinet or panel in enclosed control systems are to be adequately secured and shipped via Air-Ride carrier to prevent damage from excessive shock or vibration during shipment.

Installation Mounting
The S811+ does not require any special tools for mounting operations.
To aid with panel layout, refer to the dimension drawings on page 7–page 9. Drill holes per mounting hole location as shown. Mounting hardware may utilize either tapped holes   in the panel or lock washers and nuts to secure the soft starter.
To mount the unit, use all the hardware specified in the table below
