Code 214 – Open ground detected
This alarm indicates that the charge controller has detected a line side open ground condition.
The alarm condition will persist for a minimum of one minute, after which time the alarm
condition will clear if the ground continuity is restored.
Important!
Please note that WattStation unit will not operate correctly on isolated, ungrounded power sources. The
ground monitor feature functions by introducing very small leakage currents from line (L1) to ground,
and then checks for the presence of those currents. On isolated, ungrounded power sources, those
leakage currents won't flow reliably. In such case, the ground monitor feature can be disabled by
applying a wire jumper at input J14A (contact GE Post Sale Service).
It is possible with ungrounded power sources that unintentional "parasitic" leakage paths to ground will
be sufficient for the ground monitor circuit to be satisfied at times, so this fault may only sporadically
appear.
The WattStation unit is designed to operate correctly from either centrally grounded (e.g. L1 – N – L2) or
end-grounded (e.g. Line – Neutral) power sources. On end-grounded power sources make sure the
"hot" main is connected to the L1 input and the neutral main is connected to the L2 input.
Code 215 – Charge Controller communication fault
This alarm indicates that the charge controller has stopped communicating with the
communication controller. This should be a transient condition which should automatically
clear. If not, try cycling AC power until the condition clears. If persistent the charge controller
and/or the communication controller will need to be replaced.
