LKP Series
2.)
In some installations, when the channel voltages are balanced, the channel LEDs
will remain on, even though the bus is turned down to zero. In this case, the
accuracy diagnostics circuit is in an unstable condition and alarm faults, as indicated
by the channel LEDs, should be ignored. Note that, in general, the metering unit’s
0.1% accuracy is only guaranteed when the primary bus current is above 5% of the
full scale rating of the unit.
A relay contact output is available to connect to a remote warning system. The relay is
closed under normal operating conditions and opens when a fault condition occurs. The
output connections are available via Terminal Strip TS1 (see appropriate interconnection
diagram for location).
