LOAD LED: This red LED serves two functions. In normal operation, it
acts as an output mimic. When the channel drive is at zero, it indicates whether that
channel’s load is disconnected (or open-circuit).
To check a load, set the channel drive to zero. The LOAD LED will turn ON if there is
no load.
For levels above zero, the LOAD LED will mimic the channel output whenever a load is
connected.
Note that the channel circuit breaker must be ON for the LOAD LED circuitry to work.
