Status symbols and their description
Status symbol
Description of the status
Priority
IEC10000329 V1 EN
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.

IEC10000330 V1 EN
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) simultaneously or on ether of them.

this status
IEC10000332 V1 EN
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
Not applicable
Overvoltage reset
Stator module (SIM) and rotor module (RIM) injection outputs are protected against
voltages exceeding maximum operating range (10% of rated VT/DT for the stator and
75 % of max voltage during gain dependent time for the rotor) by a relay blocking the
injection circuit. This blocking is controlled by measuring the sense voltage, and
remains blocked by stored status in non-volatile memory. Injection block is released
by performing the following sequence:
1. Power off the REX060
2. Simultaneous press the C and key buttons
3. Power on the REX060 and wait until status indication Over-voltage is removed
from display
Stator and rotor overvoltage protection of injection circuit
Both rotor and stator have two levels of protection, injection circuit interruption
controlled by the voltage sense input and a fuse for over-current protection. The
voltage controlled interruption, overvoltage, will normally occur prior to interruption
by fuse and the reset sequence is described above. A blown fuse requires module
disassembling to replace the fuse (F 4 A 250 V for stator and F 160 mA 250 V for
rotor). However, if this occurs it is recommended to identify the reason for the over-
current and take necessary actions to reduce the current before restarting the unit. The
problem must be outside the injection unit since this unit cannot provide enough
energy to blow the fuse.
