BI2, and to 110V or 220V for BI3-BI6. In the case of a 24 / 48Vdc model, the input detection
nominal voltage can be set to 12V, 24V or 48V for BI1 and BI2, and to 24V or 48V for BI3-BI6.
In the case of a 48 / 110Vdc model, the input detection nominal voltage can be set to 24V, 48V or
110V for BI1 and BI2, and to 48V or 110V for BI3-BI6.
The binary input detection threshold voltage (i.e. minimum operating voltage) is normally set at
77V and 154V for supply voltages of 110V and 220V respectively. In case of 24V and 48V
supplies, the normal thresholds are 16.8V and 33.6V respectively. Binary inputs can be configured
for operation in a Trip Circuit Supervision (TCS) scheme by setting the [TCSPEN] switch to
"Enable". In case TCS using 2 binary inputs is to be applied (refer to Section 3.3.3), then the binary
input detection threshold of BI1 and BI2 should be set to less than half of the rated dc supply
voltage.
The logic level inversion function, pick-up and drop-off delay timer and detection voltage change
settings are as follow:
Element
BI1SNS – BI6SNS
BITHR1 *
BITHR2 *
TCSPEN
BI1PUD – BI6PUD
BI1DOD – BI6DOD
*At the PC interface software RSM100 (Relay Setting and Monitoring system), BI threshold voltage
settings are indicated by V1, V2 and V3. The V1, V2 and V3 are distinguished with 11th digit of
ordering code for supply voltage, as shown below,:
Supply voltage (11th digt of ordering cord)
110 - 220V (-1x-xx)
48 - 110V (-2x-xx)
12 - 48V (-Ax-xx)
The binary input detection threshold of BI1 and BI2 should be set to less than half of the rated dc
supply voltage.
The logic level inversion function, pick-up and drop-off delay timer and detection voltage change
settings are as follow:
