GE VMIVME-4512-300 Counter module
Make trial connections of the first CT to all three load sensor inputs, polarized both ways (a total of six connections). Record the Load Signal Out reading for each connection. Connect the first CT to the terminals that produce the highest positive reading and with the polarity that produces the highest positive voltage. The displayed Load Gain reading is limited to about 0.2, therefore a negative reading indicates a phasing or polarity error.
Try the second CT on each of the remaining
two CT input terminals, in each polarity and record the Load Signal Out reading. Connect the second CT to the terminals that produce (and with the polarity that produces) the highest positive reading. Try the last CT on the remaining input terminals, polarized both ways and record the voltage. Connect the last CT in the polarity that produces the highest Load Signal Out reading.
