We don’t use the remote setpoint option.
We are not seeing the spike. However, shouldn’t the remote setpoint match the plant setpoint prior to swapping over. Back in the old days when we had to manually swap from auto voltage control to manual voltage control it was a big “no no” to swap without matching. Not only do you have to consider what it’s doing to the machine but all of the auxiliary equipment seeing the spike – assuming you’re supplying house power.
