HIGH VOLTAGE ON LED: Lights when the HV IS ON signal from the HVPS is high.
•
EMISSION CURRENT SELECTION SWITCH: Position of this switch determines scaling of
•
remote emission current request inputs and monitoring outputs. A black plastic cap normally
covers this switch, which is factory set and should require no further attention. Figure 3-2
shows the switch set to the 300-mA position. However, for the CV-12SLX, its default setting is
1500, which means that scaling of the emission current request input and monitoring outputs
is 0-10 V dc = 0-1500 mA.

Power-Up Procedure

Follow the procedure described below when powering up the unit when it has been powered
down and lock/tagged out at the facility breaker (e.g., for maintenance).
Follow the operating instructions provided below to switch on and to adjust the HV, the filament
bias current, and the emission current.
3.5 Control of Power Supply from a TemEBeam Controller (EBC)
3.5.1 Overview of the EBC's Operations>E-Beam Screen
If your system is equipped with a TemEBeam controller (EBC), you can use the E-BEAM button
on its touch screen (see Figure 3-3) to switch the beam on and off. The HV ON and Gun ON
buttons on the Operations>E-Beam screen allow you to switch the HV and gun on/off
independently of each other. Note that if kV Control is set to Input Ctrl on the EBC's
Config>E-Beam screen, then the kV Set button on the Operations>E-Beam screen allows the
user to change the HV operating level from the default setting (10.0 kV). If kV Control is set to
Pot Ctrl, then the kV Set button becomes a flat display rectangle like those labeled Emission
and Filament, which indicate emission and filament current, respectively.

Step Action
1 If you are powering up the power supply following a maintenance
procedure, remove the lockout/tagout device from the facility circuit
breaker supplying power to the CV-12SLX. If not, proceed to Step 2.
1 Set the facility breaker switch to the ON position.
2 Set the circuit breaker switch (labeled AC MAINS) on the power
module front panel to the ON position.
3 Set the FPS ON/OFF switch (see Figure 3-2) to the ON position.
