3.0 Additional Functions
12 CC1092267A
You can also program a start-up delay of 1 – 60 seconds.
This is set in the START-UP DELAY menu item and
ensures a staggered start-up if the installation features
several compressors. This ensures that the power supply
is not loaded unnecessarily.
3.1.6 Unlimited autom. re-start after
power loss
The control system can perform an automatic re-start
after any power loss period.
You must read and apply the following safety notices
before setting unlimited automatic re-start.
Caution
In this operating mode, the compressor may start
automatically at any time and after an unlimited
length of power loss.
Check the safety notices (e.g. EN1012-1, EN60204)
that apply in your country to find out whether you
can run an unlimited autom. re-start and what
safety precautions must be taken.
Always fit the compressor with warning signs, lock
the room containing the compressor and instruct
your staff.
Fit the isolator specified by EN60204 and fit the
appropriate warning signs on it.
To set unlimited automatic restart, proceed as follows:
1. Press the
key for 5 seconds.
2. Use the or keys to enter code 8888.
3. Press the key to transfer the set code
The menu item for the max. power loss time can also
be programmed to [POWER LOSS TIME –s]. This is
the setting for an unlimited automatic re-start.
If you re-enter the code, you cancel the function.
Note
Details for locking sub menus by code can be found in
Section 3.6
3.2 [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 an
exclamation mark !.
Use the or key 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 due to the emergency stop 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 compressor 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 and faults
occurring before that are retained in the long-term memory.
The frequency with which a warning or fault occurs is
therefore always recorded.
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 (RS)
- compressor temperature and pressure
When accessed, these values flash to clearly show that
they are not the current display values.
Use the
or
key to go to the warning or fault message
of interest. Press the key, day of the week, date and
accurate time are now displayed (flashing) in the first row.
Press the key again, the status of the warning/fault of
the compressor is displayed (flashing) in the first row. If the
key is pressed again, the compressor temperature and
pressure are displayed (flashing) in the first display row.
Press the
key again to return to the normal fault
memory view.
3.3 [TIMER CONTROL]sub-menu
Caution
When programming in standby, the compressor may
start up at any time.
The timer allows you to switch the compressor on and off at
permanently set (programmed) times. You can also change
over the pressure level (e.g. night-time running at lower
pressures).
3.3.1 Setting for timer units
You will have already set the time and date as described in
Section 1.6. This setting serves as the basis for accurate
timer operations.
Go to the [TIMER CONTROL] sub-menu, use the or
key 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.
