A light load or circuit with no load will cause the “Check Install” to be displayed, for
example a transformer with no load. The meter must have at least 1% load for each
current sensor. For example model number E20-208200-(J or R)-KIT is 200 amp rated;
each of the current sensors must have at least two amps flowing though them to verify
installation. If the “Check Install” message goes off with 1% or more load, then there is
no issue with installation. “Check Install” was due to a light load; this is normal and will
turn back on during light load condition.
Intermittent “Check Install” message displays for a while and then goes off? This is
very typical with air conditioning monitoring applications. With modern air conditioning
systems a condenser coil-cooling fan runs on single-phase power and the compressor
runs off three-phase power. The “Check Install” displays when the fan is running and
will remain on until the compressor motor cycles back on. This is to be expected and is
normal.
“Check Install” display is still on with 1% load and phase rotation sequence A-B-C
verified in steps 1-4, then check for correct Current Sensor Installation.
Is the Current Sensor(s) clamped around the wire backwards?
Assemble the current sensor halves around the conductor(s) to be monitored. Ensure
each of the current sensor halves marked “ Load” (Load Side is shown with two arrows
see Fig. 29) are both facing the load side of the conductor. (The load is the side of
the conductor where the equipment you are monitoring is located.)
When removing the spit-core Current Sensor halves, DO NOT cut the tie wrap! The
head of the cable tie has a release tab. Push down on the tab to release the green
colored core.
