! EPC Shutdown on %4,
Channel [1 - 2]
The [n] channel of the Electronic Pres‐
sure Control (EPC) was temporarily shut
down. This happens when the EPC
control valve is fully opened for more
than 5s and is meant to prevent over‐
heating of the valve. This situation typ‐
ically happens when the input pressure
is too low, as from an empty cylinder.
No action required. The shutdown is
temporary and the operation will auto‐
matically resume after 15s.

! EPC ramp has no origin on
%4, Channel [1 - 2]
The starting point of the pressure ramp
was set to the current measured pres‐
sure as the setpoint value was not previ‐
ously set. When no prior setpoint is
available, this alarm is issued and the
current measured pressure is used as a
substitute for setpoint #1.
Set a static setpoint first, and then set
the ramp rate, followed by a new set‐
point. With this sequence, the starting
point of the ramp will be setpoint #1 and
the ending point will be setpoint #2.
