Operation and settingDuring the automatic self test, the alarm relays are not switchedover.5.4.3 Memory setting (on/off)Memory: on = Fault memory is activatedThe device must be reset with the RESET button afterclearing the fault.Memory: off = Fault memory deactivated (factory setting)5.4.4 Current output for external measuring instruments (IRDH375B)Factory setting: 0...20 mAThe current output of the IRDH375 can be set to "0...20 mA" oder "4...20 mA"via the menu point "M+/M-:". The maximum load is 500 Ω.Function 0...20 mA:R F = insulation fault, I= current in mAR F =20 mA x 120 kWI- 120 kWFunction 4...20 mA:R F = insulation fault, I= current in mAR F =16 mA x 120 kWI - 4 mA- 120 kWThe associated characteristic curves are illustrated on page 68.44 TGH1352en/11.2004
Operation and setting5.5 Menu ISO ADVANCED: Setting of the extended functions5.5.1 External coupling devices (AGH: no)Basic setting "no", when no coupling device is used (factory setting).AGH: 204 AK80Terminal AK of the IRDH375 is connected to terminal AK80 of theAGH204S-4. The nominal voltage range is extended to 3AC 0...1650 V. Onlycurrent converters with an output voltage not exceeding DC 1000 V are allowedto be connected (see "operation with coupling device" on page 30).AGH: 520STerminal AK of the IRDH375 is connected to terminal 5 of the AGH520S.The nominal voltage range is extended to AC 0...7200 V. Only current converterswith an output voltage not exceeding DC 1000 V are allowed to beconnected.AGH: 204 AK160Terminal AK of the IRDH375 is connected to terminal AK160 of theAGH204S-4. The nominal voltage range is extended to 3AC 0...1300 V. Onlycurrent converters with an output voltage not exceeding DC 0...1840 V areallowed to be connected (see "operation with coupling device" on page 30).AGH: 150 AK160Terminal AK of the IRDH375 is connected to terminal AK160 of theAGH150W-4. The nominal voltage range is extended to DC 0...1760 V.The coupling monitoring is deactivated when an external couplingdevice is connected.TGH1352en/11.200445
