Bender AGH675S-7 - Memory Setting (On;Off); Current Output for External Measuring Instruments

Operation and setting
41
IRDH275BM-7_D00123_06_M_XXEN/07.2018
5.4.3 Memory setting (on/off)
Memory: on = Fault memory is activated
The device must be reset with the RESET button after
clearing the fault.
Memory: off = Fault memory deactivated (factory setting)
5.4.4 Current output for external measuring instruments
Factory setting: 0…20 mA
The current output of the IRDH275BM-7 can be set to "0…20 mA" or "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 mA
Function 4…20 mA:
R
F
= insulation fault,
I= current in mA
The associated characteristic curves are illustrated on page 65.
During the automatic self test, the alarm relays are not
switched over.
When a system fault occurs at the ISOMETER®, the relay K2
will automatically be activated as a system fault relay.
