Special Considerations
Status input IN1 is
pre-assigned to be the 52b
breaker contact. IN5 and IN6 may be used to se
-
lect setpoint profiles (with input activated profiles
enabled).
Outputs 1–6 and 9–23 are form “a” contacts (nor-
mally open), and outputs 7 and 8 are form “c” con
-
tacts (center tapped “a” and “b” normally closed)
contacts. Output contacts 1–4 contain special
circuitry for high-speed operation and pick up 4
ms faster than outputs 5–8. Function 87 outputs
are recommended to be directed to OUT1 through
OUT4 contacts.
The following functions can be configured using
enable/disable output, and status input blocking
