J - Meters
Displays voltage and amperage when cutting. The ammeter can be activated
when not cutting to view an estimation of the cutting current before cutting
begins.
K - Actual/Preset Switch
The ACTUAL AMPS / PRESET AMPS spring return toggle switch, S42, defaults
to the ACTUAL (UP) position. In the ACTUAL position, the OUTPUT AMMETER
displays the output cutting current.
In the PRESET (DOWN) position, the OUTPUT AMMETER displays an estimate
of the output cutting current by monitoring the 0.00 to 10.00 VDC cutting or
marking current reference signal (Vref). The reference signal comes from the
CURRENT POTENTIOMETER with the PANEL/REMOTE switch in the PANEL (UP)
position and from a remote reference signal (J1-J / J1-L(+)) with the PANEL/
REMOTE switch in the REMOTE (DOWN) position. The value displayed on the
OUTPUT AMMETER will be the value of Vref (volts) times 80. For example, a
reference signal of 5.00V will result in a preset reading of 400 Amps on the
meter.
The switch may be changed to and from the ACTUAL and PRESET positions
at any time without affecting the cutting process.
