Digital Remote Indicator
The MK2000CB Digital Remote Indicator permanently mounts
into standard two- to xxx-gang electrical box. Low voltage wiring
connects it via the connector assembly CP-LIM2000 to the Line
Isolation Monitor.
The remote can duplicate the audible and visible "SAFE",
"HAZARD" and "OVERLOAD" (optional) signals of the LIM.
A "MUTE" button can either silence the remote buzzer (local
muting) or all buzzers in the system (system muting). The
optional "TEST" button can remotly perform a function test of the
LIM.
Additional to that there are two 7-segment-displays indicating the
Total Hazard Current and the Transformer Load current.

2. General Information
3. Technical Description
The Line Isolation Monitor is based on the superimposition of
a measuring signal on the isolated power system. The signal is
very small and near the frequency of the power line making it
compatible with all electrical equipment due to ist low EMI. This
signal is connected between each of the lines and ground and
flows through the system leakage impedances producing an
interference (beat frequency) pattern. The difference frequency
produces an envelope directly proportional to the system
leakage. This is extracted from the power line and processed.
The resulting measurement is a very accurate determination of
the total leakage current on the isolated power system.
The BENDER LIM (US Patend #4,472,676) meets or exceeds all
applicable U.S. and Canadian standards.
It complies with NEC Article 517, NFPA 99, UL 1022, and is
recognized under UL and CUL File No.E224808 (Listee:
BENDER Inc.).
