Setting 120 / 240 VAC Boost Voltage

Follow the steps below to verify and configure the low speed starter boost voltage. This is factory
configured to 240 VAC.
1 Confirm the required boost voltage for the selected tube as described above. The requirement for
the vast majority of tubes in table 2-1 is 240 V. For tubes that require 120 V boost, this is noted in
the table.
2. The boost voltage is configured via jumpers on the H.V. auxiliary board:
•
E16 to E15 selects 240 V boost.
•
E14 to E15 selects 120 V boost.
Swap the connection at E14 and E16 if the boost voltage needs to be changed. The jumper wire
(E16 - E15 or E14 - E15) will need to be replaced if making this change. Extra jumper wires are
attached to a bag on the lip on the inside of the cable access slot above the HT tank. Select the
shortest wire from this bag that will connect between the desired tabs on the board that has the
proper terminations on the jumpers. Do not discard the existing jumper; place it in the jumper kit
to be available for future configuration changes.
Proceed to the next step if the jumper setting is correct.
3. Confirm the proper boost voltage and proper anode rotation as described above.
