5 Alarm and Trip operations. The ESTAsym CPR is working with unsigned absolute values. Due to this always a positive value is shown. Independent of the direction of the changing (meas. value increase / decrease) always a exceeding of the threshold is given. -
Page 5: Application
ESTAsym CPR Doc No.: 13172 - Rev. 01 Operating instructions Page 5 of 20 2 Application High- and medium voltage capacitors taken into operation must be monitored all the time. Most of these capacitors are manufactured by using insulating oil for the dielectricum, which could catch fire in any case of fail. -
Page 6: Operation
Inputs 3.2.1 Measurement input The ESTAsym CPR has one voltage and one current input. Possible range for voltage input is 0,1-20V. The measurement range for the current input 10mA-5A. The ESTAsym CPR supervises current or voltage. It’s not possible to use both inputs parallel! 3.2.2 Blocking input... -

3.4.3 Input of numerical values Whenever the ESTAsym CPR prompts for the input of a value, the routine will be the same: A preset-value will be displayed with the first (highest) digit blinking. This digit can now be changed by use of keys. -
Page 10: Menus
ESTAsym CPR Doc No.: 13172 - Rev. 01 Operating instructions Page 10 of 20 4 Menus Info The main menu "INFO” contains all information’s about the adjusted thresholds, delay times for trip/alarm and the stored natural unbalance. In the Info menu it’s not possible to change any values. -
Page 11: Setup
The main menu “Setup” is split into two menu levels. Level 1 is the “start menu”, this contains settings to commissioning the ESTAsym CPR. Level 2 is the expert menu this menu contains all possible settings. Because of the possible settings this menu is protected by an separate password. - Page 12 ESTAsym CPR Doc No.: 13172 - Rev. 01 Operating instructions Page 12 of 20 Set the delay time for trip. If the trigger value (voltage or current) for trip is exceeded for a longer period than , contacts 11-14 will close and 11-12 will open.
- Page 13 ESTAsym CPR Doc No.: 13172 - Rev. 01 Operating instructions Page 13 of 20 The alarm relay output can be configured as either latch able or non latch able output. The alarm relay goes back to inactive state as soon as the alarm value falls below the adjusted threshold.

4.2.2.2 Current measuring The ESTAsym CPR is measuring the current at input K&L. Trip and alarm thresholds are given in A respectively in % of nominal input range. The ESTAsym CPR is measuring the voltage at input UM1 & UM2. Trip and alarm thresholds are given in V respectively in % of nominal input range. - Page 15 ESTAsym CPR Doc No.: 13172 - Rev. 01 Operating instructions Page 15 of 20 Alarm menu 4.2.2.3 Trip active When exceeding the adjusted threshold for trip, the trip relays operates, the display is blinking and shows No event following the exceeding the trip threshold.
- Page 16 Case 2: Threshold for trip is 0.5A and “drop of ratio” is 50% = trip is reset when the current falls below 0.25A. The ESTAsym CPR is working with unsigned absolute values. Due to this always a positive value is shown.
