Page 4: General
Modern fault location devices such as the EDS3065, PKA3001 or EDS470 (installed as a fixed system) make the fault location a good deal easier and shorter, and contribute in this way to a better power supply. -
Page 5: The Insulation Resistance
Week-end work was frequently necessary in order to locate the fault or faults while the system was switched off. Modern monitoring devices such as the EDS3065, EDS470 or RCMS470 solve these problems. Thanks to the automatic location of the insulation fault, the necessary fault elimination is made very simple and the required high level of insulation is maintained. -
Page 6: Basic Standards
Rapid insulation fault location is made possible thanks to insulation fault location devices such as the EDS3065, EDS470 or RCMS470. In this way, the risk of the power supply being switched off because of a possible second fault is considerably reduced. -

Page 9: Warranty Obligations
BENDER provides a warranty of fault-free execution and faultless material quality on the ions EDS3065 with all its components for a period of 12 months as from the date of delivery, under normal operating conditions. This warranty does not extend to any maintenance work, regardless of its nature. -
Page 10: Operating Principle Of The Eds3065
The test current is generated periodically by the PGH185 test device (which is a component of the EDS3065 system). The test current is limited in amplitude and time. As this happens, the system conductors are connected alternately to earth over a defined resistance. The fault current which is generated in this manner depends on the size of the insulation fault present, and on the system voltage. -
Page 11: Operation In The Rcm-Mode
Operating Principle of the EDS3065 Operation in the In the RCM mode, the EDS3065 operates according to the principle of residual current RCM-Mode measurement. In this case, only the EDS165 evaluator unit with the clamp-on probe is used, and the PGH185 test device is not required. -

4 is shifted accordingly to this value of 10 mA. Limitation of the test current to 10 mA is particularly intended for the use of the EDS3065 in DC control systems with consumers which may already operate at very low currents.

Page 39: Eds3065 In Diode Decoupled Systems
When the portable insulation fault location device EDS3065 is used in diode-decoupled systems, the aforementioned compensating (or circulating) currents will disturb the EDS3065 and will cause measuring faults. Therefore BENDER recommends the use of the EDS3065 in diode-decoupled system only according to the drawing on the previous page. - Page 40 Practical Use Practical Use EDS3065 in diode EDS3065 in diode decoupled systems decoupled systems DC - main distribution(DC 20-308 V) Central connection of insulation monitoring device (IMD) and test device PGH185 switchover EDS/IMD Us AC 230 V PGH185 Insulation monitoring device, e.g.
