Open Circuit; Breaker Locked - Maretron MPOWER CLMD16 User Manual

___________________________________________________________

Open Circuit

When lit, this read-only field indicates an Open Circuit (no load) condition. The breaker is turned ON
but there is little, or no current being drawn. There are several possible reasons:
• External switch controlling load is in the OFF position
• If the connected load is a light, the bulb could be defective
• The load is incorrectly wired
• The load is very small (less than 1.0 Amps)

Breaker Locked

When lit, this read-only field indicates that the breaker has been locked and will not respond to
switch commands on the network. The purpose of the lock feature is to avoid inadvertent or
accidental breaker state changes. The breaker must be unlocked before the breaker state can be
remotely changed again.
