How to set frequency and voltage and current gain factors

Frequency, current and voltage gain for the stator and/or rotor can be set and stored from the injection
unit HMI. The display shows the latest stored settings.
The settings are stored in non-volatile memory, which means that they remain stored in case IED is
powered off.

Status symbols and their description
Description of the status
Over voltage occurred, injection is blocked. This can occur on both X61/62
and X81/82 (Stator & Rotor) simultaneously or on either of them. The symbol
is displayed in the status column (column 1) in row 2 for X61/62 and in row 4
for X81/82. The injection is blocked until a manual reset of the blocking occurs.
Injection blocked by the injection switch. The symbol is displayed in the status
column (column 1) and is always shown in both row 2 and 4.
Injection blocked by binary input. Blocked injection will be shown in the status
column (column 1) depending on binary in status. This can occur on both
X61/62 then shown in row 2 and X81/82 then shown in row 4 (Stator & Rotor)
Ø
simultaneously or on ether of them.
Analog output saturation. This status is set when the analog signal, current
and or voltage, to REG670 IED is too high and may thereby be incorrect due
to saturation in amplifier stage. Saturation status will be shown in the status
column (column 1) in row 3 or 5 depending on the saturation occurrence
