CB3 controls the power to coolant pump only. It can be blown by an overload of the coolant pump motor or a short in the
wiring to the motor.
CB4 controls the 115V AC to the air solenoids, 4th axis brake, and the oiler. It is never expected to trip. If it does trip, it is
likely caused by a short circuit in the wiring on the I/O assembly or the wiring to the solenoids on the spindle head.
