Non-volatile memory function on the 3UG4583
The 3UG4583 insulation monitoring relays also have a con󹪝gurable non-volatile (retentive) fault
storage function. After shutting down and restoring the rated control and supply voltage, the
device is in the state it was in prior to shutdown, until it is reset.
If fault storage is activated using DIP switch 2 (ON), output relays K1 and K2 remain in the fault
state and do not switch back to their original position until actuation of the combined Test/Reset
button, or until activation of the remote reset (jumpering of terminals Y2/Y3) if the measured
insulation resistance is greater than the set threshold(s) including hysteresis. Fault storage is
non-volatile.
The table below shows the di󹪜erent options for resetting the device depending on the setting
of DIP switch 2.

If there is no external connection between terminals Y2 and Y3 while retentive fault storage is set,
internal device monitoring detects a parameterization error.
You will 󹪝nd the adjustment ranges and factory settings of the available parameters and the
de󹪝nitions of the DIP switch positions in Chapter "Operator control (Page 188)".
