The LEDs to the right of the screen indicate which value is being displayed. When
both kW and V are lit, frequency is displayed (in kHz). When both V and A are lit, the
reverse time is displayed (in µs). Repeatedly pressing the DISPLAY button will cause
the display to cycle in the following order: kW, V, A, freq (frequency in kHz), and t-
rev (reverse time in µs).
When a fault or software error occurs, the error codes scroll across the display (for
example, E004...E002...E004...E002). These codes scroll indefinitely until you
correct the errors. For a detailed explanation of the error codes and other
troubleshooting materials, see the “Troubleshooting” chapter.
LEDs
Table 4-7. Display Panel LEDs
POWER ON
Lights green when input power is on
OUTPUT
Lights green if output power is on
SETPOINT
Lights green if the Pinnacle Plus+ supply is operating
within set point; accuracy is within 0.4% of full scale or
2% of set point, whichever is greater
INTERLOCK
Lights green if all interlock conditions have been met
BUS FAULT
Lights green when a bus fault occurs
OVERTEMP
Lights green if the Pinnacle Plus+ supply has exceeded the
maximum operating temperature
ARC
After the output has been turned off, this LED lights green
for a predetermined time if the hard arc count limit was
reached during the previous run. You define this limit. The
ARC LED will be activated under two different conditions:
1. If the hard arc count limit is non-zero and the number
of hard arcs seen exceeded this limit during the last
run, the pulse will occur when the output is turned off.
2. If the hard arc count limit is set to zero, this signal will
pulse for a predetermined time for every hard arc seen
by the unit. If another hard arc is seen before the last
pulse is complete, the pulse width will be refreshed to
the full width.
