Description
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.
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.
Description
Protocol error detected, such as receipt
of a non-DATA packet or lack of an ex‐
pected message acknowledgment. Most
likely the gateway settings on the SNE
are wrong.
The TFTP client didn't receive a re‐
sponse from the server.
The data packets requested by the TFTP
client to not match those sent by the
TFTP server. Either the TFTP client or
TFTP server is not working properly.
which to communicate. SNE or host com‐
puter is low on resources.
Too many TFTP load requests have
been commanded.

ized. Usually a problem of resource.
Action
No action required. The shutdown is
temporary and the operation will auto‐
matically resume after 15s.
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.
Action
Power up the SNE connected to a serial
terminal and change the settings in the
startup dialog.
Verify that the TFTP server is running
on the host computer, and that the host
computer is connected to the SNE
through the network.
Reset the SNE.
Restart the TFTP server on the host
computer.
Wait for problem to clear.
Contact Customer Support.
Only request one TFTP load at a time.
Verify that the SNE has sufficient mem‐
ory.
Upgrade SNE.
Reset SNE.
Verify that the SNE has 16Mb SIMM.
