Visually inspect the line filter capacitors and connecting wires for any discoloration or
bulges in the canisters.
For PT Small Frames, disconnect the wires from the capacitor being measured, noting
where they were connected. Use a multi-meter to measure capacitance between the
terminals of one capacitor at a time. If the capacitance of either is below the 50%
Capacitance value in Table 26, contact Phase Technologies for replacement.
For PT Medium and Large Frames, disconnect wires from L2 and use a multi-meter to
measure between L1 and L2, then measure between L2 and L3. If either capacitance
measured is below the 50% Capacitance value in Table 26, contact Phase Technologies
for replacement.
