This guide will show you how to connect the Polar Monitoring Gateway to the LS ELECTRIC S100 Variable Speed Drive. It will also take you through the setup and parameters required on the LS ELECTRIC S100 to ensure communications to the Polar Gateway.

Steps to follow:

Connect power to the Gateway.
Connect RS-485.
Final checks.
Power on the system.
Configure the LS ELECTRIC S100 Serial Parameters.

LS ELECTRIC S100 Connection Setup

1. Connect power to the Gateway.

A. Power the gateway from an external power supply.

Wire the Polar Gateway to a 12-24 V DC power supply. Connect the positive wire to the positive terminal and the negative wire to the negative terminal.

B. Power the gateway from the VSD.

Wire the Polar Gateway directly to the VSD. Connect the positive wire to the +24V(24) terminal and the negative wire to the (EG) terminal.

2. Connect RS-485.

Wire the RS-485 cable to allow communication with the Polar Gateway. Connect A+ => S+ and the B- => S- . What is RS-485?

3. Final checks

Before switching on the Gateway and the device, make sure you have completed all the previous steps correctly.

Make sure the wiring is secure – no short circuits.
Ensure that all connections are secure on the device and the gateway.
Re-check the RS-485 twisted pair cable is correctly wired.
Check that the A and B are correctly wired to the device.

4. Power on the system

Now you are ready to go, you can now switch on the Polar Gateway and the LS ELECTRIC S100.

5. Configure LS ELECTRIC S100 Serial Parameters

In order for the Gateway to correctly communicate with the LS ELECTRIC S100 controller, there will need to be some changes made to the communication parameters.

Note: It is critical to change the default settings to reflect the table below.

Serial Communication Setup

Name	Description	Parameter	Default	Required
Communication Address	Device ID/Unit ID/Node ID	Int485 St ID	1	1
Serial Speed	Communication Speed	Int485 BaudR	3=9600	3=9600
Data Format	Stop bit, Data bits and parity	Int485 Mode	0=D8/PN/S1	0=D8/PN/S1
Protocol	Communication protocol	Int485 Proto	0=Modbus RTU	0=Modbus RTU

	Remote Control Setup
Name	Description	Parameter	Default	Required
LOCAL/REMOTE Selection Source	Set dr.90 to 2(Local/Remote)to perform	dr.90	2=local/ remote	2=local/ remote
	local/remote switching using
	the [ESC] key
