eSL Manual
eSL Model Number
Each time you turn on the AC power and close the front panel circuit breaker the eSL will display its
model number on the front panel. You will see something like:
eSL 30P300
eSL indicates this is the eSL series. 30 stands for 30kV (maximum output voltage). P is for positive output
polarity (N would be for negative output polarity). 300 stands for 300 watts (maximum output power).
This screen will clear in a few seconds and display the standard Standby/HVOFF screen.
Local Front Panel Operation
The eSL uses the current (left most) encoder to operate the front panel controls. Pushing the current
encoder once will bring you to the menu screen. Rotating the current encoder will allow you to select
the various operational setup submenus. Pushing the current encoder scrolls through the affiliated
sections, allowing you to make selections and exit to the previous menu.
Front Panel Meters in Standby/HV OFF
Turning on the power to the eSL and closing the front panel circuit breaker will place the eSL into the
Standby/HV OFF mode. The front panel kV and mA meters are active in this mode showing actual kV and
mA. Because the power supply was just placed into HV OFF they typically will show zero, but had the
unit just been in HV ON and placed into HV OFF residual output voltage could be shown especially if
there is a light or no load condition. Even though the meter is showing the actual output voltage, do not
rely on this measurement to touch anything connected to the output.
Only touch the output after disconnecting the AC power for a minimum of five (5) minutes and using a
short circuit stick to discharge the output to ground. Danger: Failure to follow these instructions could
have fatal consequences.
