Chapter 1 Introduction 1. Introduction 1.1 About This Manual This manual is intended to assist the user in the installation of the SA300 Series (ezPAC™) Substation Automation Unit. The term ‘SA300’ is used herein to refer to all models in the series. This chapter gives an overview of this manual and an introduction to the SA300. Chapter 2, Installation, provides instructions for mechanical and electrical installation.
• Programmable Controller (32 control setpoints, OR/AND logic, extensive triggers, programmable thresholds and delays, relay control, event-driven data recording). Ability to block relay outputs with a special control algorithm.
Remote Displays The SA300 can be ordered with an optional LED Remote Display Module (RDM) or LCD Remote Graphical Module (RGM). Both have a fast RS-485 port and communicate with the SA300 through the Modbus RTU protocol. Remote displays can be located at distances of up to 0.5 km from the device. The RGM can also be ordered with an Ethernet 10Base-T port and can communicate with the SA300 through a local network. The RDM has three six-digit windows with bright red LEDs well suited for dark areas.

2.2.6 Digital Inputs There are two possible module types: a) 16 Digital Inputs, b) 16x2 (32) Digital Inputs. Optically isolated digital inputs in one digital input module are provided for status monitoring and external synchronization of power demand period and time. Dry or wet contacts may be connected to these inputs, as shown in Figures 2-10, 11, 12, and 13.

Relays There are two possible variants: a) 8 relays in one Relay Output Module. b) 8x2 (16) relays in one Relay Output Module. These output are provided for alarms, remote control or energy pulsing, as shown in Figure 2-14 and 15. For ratings, see Appendix: Technical Specifications.
2.2.7 Analog Output The SA300 provides 4 optically isolated analog inputs and 4 analog outputs with internal power supplies. Current output options are: 0-20 mA and 4-20 mA (current loop load of up to 500 Ohm), 0-1 mA and ±1 mA (current loop load of up to10 kOhm), as shown in Figure 2-16.
2.2.8 DC Voltage Input SA300 models are provided with one DC voltage input, which can be used for measuring of substation storage battery voltage (see Figure 2-17a), or for measuring unit power supply voltage (see Figure 2-17b). Copper wiring 1.5-2.5 mm2 (15 –13 AWG) should be used.

Chapter 4 Changing the Battery 4. Changing the Battery When the battery level drops below the minimum allowed threshold, the red MEM.BAT.LOW LED on the front of the device is lit up, indicating that the battery should be replaced. Use the following procedure: 1. Use a flat screwdriver to open the battery compartment, turning counter-clockwise. 2. Remove the battery cover and the battery 3. Replace the battery - with the plus towards the outside - and close the compartment.
