Hello Steven,</div>

Brian and I just double checked the pinout for the connectors at the turret flanges, connectors B1, B2 and B3 to make sure that we have the correct wiring for the voltage taps.</div>

Based on the Oxford drawings, we found that besides of the the voltage taps wires, there are wires in B1, B2 and B3 connectors that goes to the sorb heaters and magnet shell heater (total of 6 wires: 2 wires for each sorb heater and another 2 wires for the
shell heater).</div>

Will these heaters be used/wired? <br>

By looking at the Controls-CLEO spreadsheet, I can see that at some point two relay channels were assigned for the sorb heaters but we do not have any drawing or cable planed to be used for these heaters.</div>

We need to know this before starting the fabrication of the voltage tap cable.</div>
