Sedecal SHF-310 - Filament Stand-By Current

Calibration

• Verify position of dip switches on the HT Controller Board during every
calibration procedure:
DIP SWITCH OPEN (OFF) CLOSED (ON)
3000SW2-2
Position during operation -- Enables Filament and
Rotor Interlocks
Disables Filament and Rotor Interlocks
(this turns off the filament so no radiation will
be produced during the exposure).
3000SW2-4 Position during operation -- Digital mA Loop Closed Digital mA Loop Open / Filament Current Constant
Only for Generators with Low Speed Starter (LF-RAC) (it does not
apply to Generators with High Speed Starter - LV-DRAC):
-- When the Digital mA Loop is open (dip switch 3000SW2-4 in
“On”), the rotor runs for two minutes after releasing the handswitch
button from “Preparation” position. After this time the rotor will
brake (unless DC Brake is removed).
-- When the Digital mA Loop is closed (dip switch 3000SW2-4 in
“Off”), the rotor will brake after releasing the handswitch button
from “Preparation” position (unless DC Brake is removed).
• Be sure that X-ray Tubes configured in E02 and E18 Memory Locations
correspond to X-ray Tubes installed (refer to Configuration document).
2.1 FILAMENT STAND-B Y CURRENT
For RAD Only Generators, the Filament Stand-by value is
auto-calibrated by the Generator and automatically stored into the
respective Memory Locations (E01 and E17). Filament Stand-by
values are not field changeable.
For RAD and Fluoro Generators, E17 Memory Location (”Fluoro
Filament Setting”) sets maximum patient Entrance Skin Exposure
Dose Rate. (Refer to Section 2.7 “Fluoro Calibration”).
