overcurrent condition for
longer than was set on the
overcurrent timer.
No suggested action.

Short Circuit
Condition
One of the following
short circuit conditions
occurred: a shorted
chamber, shorted cable,
or a failed pulsing switch.
The unit detects a short
circuit if the following
conditions exist:
• the power, current,
or voltage limit is
active (or enabled)
• the current is above
the current threshold
of pulsing
• the unit detects a
hard arc.
Cycle AC power to the
unit.
E092
No Master Detected
No master system is
detected. At least one unit
must be set as the master
unit.
Verify a unit is set as the
master unit, or that the link
to the master unit has not
been broken.
E093
Invalid Frequency
An invalid frequency has
been set to properly
operate the unit.
Reset the frequency for the
unit.
E095
Reverse Time Limit
Exceeded
In a stand-alone dual unit,
most likely you have set a
higher voltage limit for
the receiver side than for
the transmitter side. The
maximum reverse time is
inversely proportioniate
to the voltage limit.
Reduce the reverse time set
for the transmitter side, or
lower the voltage limit in
the receiver side.
