10.10 Alarm relay
The alarm relay triggers in
‘OPERATION’
(normal mode) if an error occurs which
has been defined as
‘ERROR’
and not
just as
‘WARNING’
.
The error message
‘ALARM’
in the con‐
tinuous display is marked with a ✱ (star)
and can be acknowledged with the key.
The alarm and the ✱ will then disappear.
10.11 "Error logger" operating
mode
The last three errors are displayed. Also
displayed is how long ago (in minutes)
they occurred. When a new fault occurs,
the oldest fault is deleted.
Faults are only shown which occur in
operating status
‘OPERATION’
, i.e. not in
operating status
‘STOP’
,
‘CAL’
(user cali‐
bration),
‘HOLD’
or
‘ PAUSE’
.
Only
‘ERRORs’
are shown, not
‘WARNINGS’
, e.g. a
‘LIMIT ERR’
is
shown, but not
‘ LIMIT↑’
.
A fault, whose display has lasted for 999
minutes is automatically deleted from the
‘Error Logger’
. The
‘Error Logger’
is nei‐
ther saved nor backed up in the event of
power loss.
