Message description
“Idling....”
Front panel or remote interface turned off
compressor. All is well.
“Running Normally” Compressor is running. All is well.
“Starting...”
Compressor ON request received, and
compressor will start within 10 seconds unless an
error occurs or a stop request is received.
“Helium Over Temp Recovery
Delay…. WAIT x”
(x is a number, counting down, in
minutes & seconds. When x is zero
compressor will start)
Compressor ON request received and
compressor will be able to be restarted in x
amount of time unless an error occurs or a stop
request is received. This message will show
when the compressor has encountered certain
errors that require a minimum off time, such as
“Helium Temp. too high”
“You have had 6 errors in less than
an hour: mm:ss”
mm:ss indicates them minutes :
seconds until the compressor can be
reset.
The compressor has entered a locked-out state
due to experiencing 6 errors within one hour. The
compressor cannot be restarted until the error
lockout has been reset. You must select the
lockout menu and reset the number of lockouts.
In doing this you must acknowledge the relevant
errors and therefore take the necessary steps to
prevent these errors from reoccurring. Resetting
the lockout status will enforce a 30 min cool down
period before the compressor can be restarted to
prevent the short-cycling of compressor module.
The lockout contributors are noted in Section
7.6.5.
