5.2 [ FAULT MEMORY ] sub-menu
Warning messages and faults are stored in the fault
memory. The last warning message or fault recorded is
always at the top. In order to distinguish between faults
and warning messages, faults are marked with a
!
.
You can use
or
to switch between the individual
memory areas in the fault memory.
The faults are displayed as follows:
03! EM-STOP 000100h
a)
b)
c)
d)
a) The same fault has occurred three times.
b) This relates to a fault.
c) Fault has occurred as a result of the emergency off
button being pressed.
d) Fault occurred at 100 running hours.
03 HIGH
TEMP 000100h
a)
b)
c)
a) The same warning has occurred three times.
b) Warning resulting from final compression
temperature being too high
c) Warning occurred at 100 running hours.
The last eight warning messages or faults recorded are
displayed in the fault memory. All messages/faults
occurring before that are however retained in the long-
term memory. The frequency with which a warning or
fault occurs is therefore always recorded.
However you can access more detailed information on
warning messages and faults that have been recorded -
in the fault memory. The following are saved for every
warning message/fault recorded:
- time and date
- compressor status (e.g. on-load)
- speed
- final compression temperature, final compression
pressure and line pressure
When accessed, these values flash to clearly show
that they are not the current display values.
To access this information please use
or
to go to
the warning message or fault that you are interested in
in the fault memory.
The information set out above relating to the status of
the compressor at the time of the fault can be called up
in turn by pressing the
button several times.
5.3 [ TIMER CONTROL ] sub-menu
Danger
When programming in standby, the machine may
start up at any time.
The timer allows you to switch the machine on and off
at permanently set (programmed) times. You can also
change over the pressure level (e.g. night-time
lowering).
5.3.1 Setting for timer units
You will have already set the time and date as
described in section 2.3. This setting serves as the
basis for accurate timer operations. If you have not yet
set the time and date, please do so now.
Please go to the
[
TIMER
CONTROL
]
sub-menu
where you can use
or
to select from seven
different timer units. The status line of each switching
unit is as follows:
a)
b)
c)
d)
1 _______ 00:00 00:00
a) Unit no.
b) Days of the week
[SMTWTFS]
= Sunday, Monday ..
c) Switch-in point
d) Switch-out point
If there are no days of the week selected in the
switching unit line, the switching unit is not active. The
switching unit only becomes active when the day of the
week is set. When the
is pressed, the first
underscore _ starts to flash. You can now use the
key to set the first day of the week (Sunday). Then use
the
key to confirm the day of the week. The next
underscore _ then starts to flash. If you do not want to
confirm a day of the week as set, please immediately
press
.
You can run through all seven days of the
week in this way. Once you have confirmed the last day
of the week (Saturday), the first unit of the switch-in -
point starts to flash. You can either set this using
or
.
