Press this button to view the voltage present in
Out 3
(auxiliary
variable 0-250 VDC).
Out 3,
located in the center section of
the PTE-100-C PRO panel, is switched on, regulated and pro-
tected independently from the other outputs.
A green LED above its tap will identify the displayed output. If you want to
lock the Display #2 to Out1, Out2 or Out3, press the corresponding dis-
play selection button and hold it for 5 seconds until you hear a beep. To
return to the normal ammeter function, give a brief press to any of these
buttons.
Current tap selection.
The PTE-100-C PRO cannot detect which of the current taps is
connected the load to. Though the current value shown by Dis-
play #2 is common to the four taps, some special functions, overload pro-
tections and calculations require that the current output tab to which the
load is actually connected is identified to the unit. Press this key to sequen-
tially signal the 100 A, 50 A, 25 A or 5 A tap in use.
Though this will not affect the output current nor the value shown in Display
#2, we strongly recommend you to do it whenever you move your connections
to a different current output.
Power Section Alarms
The PTE-100-C PRO’s power section is protected form over-heating and
from overload. These conditions will automatically switch the power output
off and will be signaled by these two orange-colored 3-mm LEDs:
•
I Therm.
An internal sensor will protect the unit from overheating. This
alarm automatically disappears when the unit cools down to
normal temperature. Operation can then be resumed.
•
I Lim.
This protection operates when the upper limit of the selected
current tap, or the limit optionally set with the “Ilim” special
function, whichever is lowest, has been exceeded.
Up to 250 A can be attained from the 100A/10V tap for 3 seconds
before the unit’s thermal protection trips. Refer to the duty cycle
chart in the CURRENT AND VOLTAGE INJECTION chapter to learn
more on how to get currents higher than 100 A from this tap.
