10.2 Current Sensor Diagnostics
NOTE: Light Load or No Load May Cause “Check Install” Error to be Displayed.
The meter must have at least 1% load for each current sensor. For example model
number E20-208200KIT is 200 amp rated; each current sensor must have at least two
amps flowing though it to verify installation. If the error goes away with 1% or more
load, then there is no issue with installation. The error was due a light load this is
normal and may go back on during light load conditions.
STEP 1: LINE VOLTAGE PHASE ROTATION MUST BE CORRECTED
PRIOR TO CURRENT SENSOR DIAGNOSTICS - SEE SECTION 10.1.
Is the Current Sensor(s) clamped on backwards?
Assemble the current sensor halves around the conductor(s) to be monitored. Ensure
the current sensor halves marked “Load” (Load Side shown with two arrows Figure 24
below) 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). WARNING: If removal
of the split-core Current Sensor is necessary, DO NOT Cut the Tie Wrap! The head of
the cable tie has a release tab. Push down on the tab to release.
How do I know line from load?
Generally speaking, “line” is the power coming in or “upstream” to a circuit breaker/
fuse/disconnect/etc. “Load” is the power going out (“downstream”) of the device that
interrupts power.
