Low Speed Boost Time
When you press the PREP push-button there is a delay before the green PREP LED illuminates.
This delay is the Rotor Boost Time.
During this time the rotor is accelerated to approximately 3600 RPM, the filament is boosted to the correct temperature, all the interlocks
are checked (including the rotor interlock) and the Pre-Charge and Charge sequences are initiated.
If you have selected (50) or (60) for Pre-Set# [≡22], you may select a Rotor Boost Time.
Using the Up/Down push-buttons for the mAs Display, scroll through the Pre-Set #s until you have [≡23] displayed on the mAs Display.
The Factory Setting for this Pre-Set # is [1.7] sec.
Select a value for Rotor Boost Time.

NOTE: The minimum value is [1.7] sec. This is the minimum time necessary
for the filament temperature to stabalize when changing from Standby to the
mA Station selected for exposure.
Interlock Selection
The generator provides for two independent interlocks with LED Displays on the Operator’s Console.
They are Collimator Interlock and Door Interlock. In addition, there is a Thermal Interlock for the X-Ray Tube.

NOTE: For Tube Thermal Interlock, Collimator Interlock, and Door Interlock you
have two choices on the Time Display; [0] or [1]. [0] = disabled, [1] = enabled.
Tube Thermal Interlock
If you have connected a Thermal Interlock for the X-Ray Tube to J9, pin 9 on the SPB pcb (refer to Figure 3-5) select a [1] for Pre-Set #
[≡24]. If not select a [0].
Collimator Interlock
If you have connected a Collimator Interlock to J4, pin 5 on the BBU pcb (refer to Figure 3-7) select a [1] for Pre-Set # [≡25]. If not
select a [0].
Door Interlock
If you have connected a Door Interlock to J4, pin 6 on the BBU pcb (refer to Figure 3-7) select a [1] for Pre-Set # [≡26]. If not select a [0].
Software Version
Pre-Set # [≡27] will indicate the Software Version of the generator.
