Specifications
Rear Panel Connections and Configurations
Each output channel is independently programmable with output quantity
(Vab, Ia, Fault Location, etc.) and range.
Contact Outputs
The rear panel has six relay contact outputs (A1–A6). These outputs indicate
fault conditions and acknowledge reset commands. An additional relay
contact indicates self-test failure or other alarm conditions. All contact outputs
are dedicated and not programmable.
Table 2.2 shows contact assignments
and signal descriptions.
