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 (<strong>IRDH375</strong>B)Factory setting: 0...20 mAThe current output of the <strong>IRDH375</strong> 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
