System Frequency(HZ) Where to set External Power Input Frequency, based on External Power Input, RTS controls

output(current/voltage). When External Power Input is 60, output(current/voltage) frequency is 60 . Selected External Power Input frequency is used to calculate time(Second, Cycle) and current/voltage.

CT Ratio(x:1) Where to set CT Ratio of Relay, it is useful to display converted Output Current.

System Max Current(1-10A) Where to set Max Input Current of Relay, it alarms when Input Current is larger than Max Current and Output Current is stopped when Input Current is continuously coming after Max Current Limit Time.

Max Current Limit Time(1-30s) Where to set Max Current Limit Time, in order to stop output current after Max Current limit time when larger Input Current than Max Current

Sequence Time Limit (10-990s) Where to set Sequence Time Limit, sequence is stopped after sequence time limit, if sequence continuous when OCR/External Mode test

External Debounce Time(5-200ms) Where to set External Debounce Time in order to remove a trembling signal from External Input(IN1, IN2) when Relay test on External Mode

Moment Time Limit(50-1000ms) Where to set Moment Time Limit, it’s the duration of withstand current flowing to the Relay. On “START” after the duration it automatically “STOP”

Trip Time Offset(0-1000ms) It displays the sum of Trip Time Offset value and the Trip Time result from OCR Mode and

External Mode test, on LCD. RTS operation time refers to “4. RTS Operation Time”.



Close Time Offset(0-1000ms) It displays the sum of Close Time Offset value and the Interval Time result from OCR Mode and

External Mode test, on LCD. RTS operation time refers to “4. RTS Operation Time”.

Sequence Counter(1-4) Where to set Sequence Counter number for reclosing Relay or Recloser test. It can be set on OCR Mode/External Mode by pressing [ENTER].

2.3. Recloser Control Interface - C

Figure 2-3. Recloser Control Interface

Operation Switch It shows the state of Recloser and it’s the close/open switch.

Control Cable It’s the connector interfacing with Recloser Control.

Current EVRC Recloser control gets RTS burden when current is larger than 7A and current wave gets

distorted. RTS burden ratings refers to "2.4 Output Current”.

Voltage Va, Vb, Vc are always loaded with voltage but VL(Load side) is loaded when (ON) close status

GAS It’s sets for 0bar when EVRC2A Control and Cable connected to each other Recloser Control can be tested in OCR MODE.

Do not use Output Current Terminal when Recloser Control Interface is used
