Current when disconnected = 10A (1/2)
= 5A
Current when disconnected = 10A 1
= 10A
The heater disconnection detection current value when disconnection occurs on the common side is as
follows.
Heater disconnection detection current value = (17.3 +5)/2 ≒ 11.2 [A]
The heater disconnection detection current value when disconnection occurs on the load side is as
follows.
Heater disconnection detection current value = (17.3 +10)/2 ≒ 13.7 [A]
Hence, the heater disconnection detection current value is to be 13.7 A in order to detect disconnection
in both cases.
■ Example of parameter setting
The following is an example when CT 1 and 2 are installed on the outputs 1 and 2 respectively in the
connection shown above and CT abnormality is provided as output on the output 3.
