Page 28: Using Programming Switches
3.2. Using programming switches Before system implementation, check the positions of the programming switches in accor- dance with the following basic principles: Each I/O unit connected to the communication bus has its own address (each I/O unit have an unique address). Set the programming switches before connecting the supply voltage. -
Page 29: Programming Switches - I/O Units
Switch 8 determines the mode of the master unit. When the switch is in the ON position the master unit operates in SUB-UNIT mode; in the OFF position the master unit serves as the master unit for the entire system. NOTE! If several master units are connected to the same communication bus, only one unit may operate in MASTER UNIT mode. - Page 30 Other programming switches have different functions in different units, as described below. Attention! Note the position of the ARC-EP10-2/2.0, ARC-EP10/2.0 and ARC-EC1/2.0 dip switches. Figure: Programming switches for ARC-EL3/2.0, ARC-EP10/2.0 and ARC-EP10-2/2.0 ARC-EP10/2.0, ARC-EL3/2.0 Switch 1 determines which light activation activates the arc stage. When the switch position is ON, the arc stage only activates on the light information provided by the unit‘s own sen- sors.

Page 37: Introduction
Introduction This User’s Manual contains a functional description of the protection system, application ex- amples and technical data. Installation and user instructions can be found in the Operation and confi guration instructions. 5.1. Purpose The main purpose of the arc protection relay is to protect an electrical installation against the destructive impact of an arc short circuit, minimize physical damages and mitigate potential injuries. -
Page 38: Functions
Functions 6.1. Protection functions The arc protection functions of the arc protection relay are always operational. You can select the circuit breaker failure protection stage using the programming switches. 6.1.1. Arc (fault) protection Arc protection involves the master unit, I/O units, a range of light sensitive elements and a instantaneous overcurrent stage module. -
Page 39: Measurements
6.2. Measurements The master unit ARC-EM/2.0 has a three-phase current measuring function that can be used to measure either three phase currents or two phase currents and a summation current. Cur- rent measuring is indicated on the display of the master unit. The current I/O unit ARC-EC1/2.0 has a current measuring function but no indication. -
Page 40: Bi/O Bus Interface
6.5. BI/O bus interface All ARCON 2.0 Arc Protection System units can receive or transmit light and/or current crite- ria (depending on the unit) on the BI/O bus. ARC-EM/2.0 can send BI/O information to two master units or two protection relays. If there are more than two recipients of BI/O information or the length of the BI/O bus exceeds 100 m, the BI/O bus must be equipped with a line amplifi... -
Page 41: Connection To I/O Unit
6.5.1. Connection to I/O unit Each I/O unit also has a BI/O bus. The light I/O units (ARC-EP10-2/2.0, ARC-EP10/2.0 ARC-EL3/2.0) can transmit trip information to the master unit or current I/O unit. The current I/O unit (ARC-EC1/2.0) can receive the light information and send the current information to other I/O units. -
