Command Name: SET NEUTRALIZER CURRENT
Syntax: NI[n]<cr>
Units: MPS-3000 CE FC: amperes
MPS-3000 CE PBN: mA
MPS-3000 CE HCN: mA
Range: MPS-3000 CE FC: 0.00 - 15.00
MPS-3000 CE PBN: 0 - 600
MPS-3000 CE HCN: 0 - 600
Description:
MPS-3000 CE FC:
Used to set the neutralizer filament current target. The filament current
will ramp to this value when the MPS-3000 CE FC power supply is in
Manual mode. In all other modes, this command has no effect, but is
still accepted. The command will not be accepted if the entered value is
greater than the neutralizer current limit (NL[n]).
MPS-3000 HCN/PBN:
Used to set the emission current target. The emission current will ramp
to this value when the MPS-3000 CE HC/PBN power supply is in Man-
ual mode. In all other modes, this command has no effect, but is still
accepted.
Set the MPS-3000 CE FC neutralizer filament current target to 4.50A using
the following command: NI4.50<cr>
Set the MPS-3000 CE HCN/PBN emission current to 250mA using the fol-
lowing command: NI250<cr>
Command Name: LOCKOUT FRONT PANEL SWITCHES
Syntax: NK[n]<cr>
Units: N/A
Range: n = 0 or 1
Description:
When enabled (NK1), all of the switches on the power supply’s front
panel will not function. Also, the alarm will not sound on any fatal of
non-fatal error.
When disabled (NK0), all switches and the buzzer act normally. The
value of the NK command is stored in non-volatile RAM and stays in
effect until it is changed. If SW1-8 is in the off position, the front panel
will be unlocked following a power cycle. To maintain a lock on the
front panel, SW 1-8 should be set to the on position.
Lockout the front panel switches using the following command: NK1<cr>
