Saturation
When the voltage or current amplifiers in an injection module saturates due to high
voltage level, it is indicated with a warning symbol in the status column in the REX060
display . Besides this a binary out for the specific module is set active to indicate to the
IED that the signal may not be reliable due to saturation and could cause incorrect
measurements.
Binary in
The injection can be blocked by application in the IED. For this purpose, two binary
inputs to the REX060 exist:
•
BLOCK on X61 terminal 1, 2 or 3: Prohibits injection on the injection unit
inserted in X62
•
BLOCK on X81 terminal 1, 2 or 3: Prohibits injection on the injection unit
inserted in X82
The used terminal is depending on actual binary voltage, pin 1 for 220 V, 2 for 110 V,
3 for 48 V and 4 for return (common).
Binary out
The following binary outputs exist on the REX060:
•
INJ_BLOCKED_NC on X61 terminal 5:
Indicates to the IED that the injection on X62 is blocked. The reason for blocking
is indicated in the REX060 LCD.
•
SAT_NO on X61 pin 6:
Indicates to the IED that there is a risk of saturated amplifier on voltage and/or
current output at X61, indication is also given in the REX060 LCD.
•
COMMON on X61 terminal 7:
Common return for X61 terminal 5 and 6
•
INJ_BLOCKED_NC on X81 pin 5:
Indicates to the IED that the injection on X82 is blocked. The reason for blocking
is indicated in the REX060 LCD.
•
SAT_NO on X81 pin 6:
Indicates to the IED that there is a risk of saturated amplifier on voltage and/or
current output at X81, indication is also given in the REX060 LCD.
•
COMMON on X81 terminal 7:
Common return for X81 terminal 5 and 6
Power status
•
X11 terminal 3:
Fail, power off NC
•
X11 terminal 1:
Ready, power off NO
•
X11 terminal 2:
