General 1.4 Parameter change
Number of compressors
and interval period
‚Priority Change’
The control can be used as follows for 2 or 3 compressors. Independently of
this, if the compressors are the same size, a cyclical (cycle time greater than
0) or if the compressors are different, a time-dependent (cycle time to 0) prior-
ity time change can be carried out as follows:
1. Input Code 832, as described in ‚Fundamental Procedures’
→ In the dis-
play appears for example: 3 x 002 h, and the left number (here ‚3’) blinks.
2. Use arrow keys / to set the number of compressors to be consid-
ered, then use ENTER key to quit
→ now the right number blinks (here
‚002’).
3. Use arrow keys / to set the priority change interval time to the de-
sired value and then use ENTER key to quit
→ the display changes
according to the following criteria:
– If the selected interval time is greater than zero, the display mentioned
in 8.) appears ‚Pressure + Time to next priority change’
– otherwise the text under ‚Switching Times’ appears and as soon as the
switch time input is completed text under ‚Time’ appears.
Switching times
As soon as the cycle time has been set to ‚zero’, the control considers the
switching times, which are input, as described, in the 26 timer channels A...Z.
1. Input code 798, as described in ‚Fundamental Procedures’ – For example:
A 0 00:00h = 123, appears in the display and the left letter (here ‚A’) blinks.
2. Use arrow keys / to select the desired switching channel (A...Z) and
use ENTER key to enable its change
→ now the left number blinks
(here ‚0’ means: this switching canal is not active).
3. Use arrow keys / to input the desired Switching -day -No. (1...7) and
use ENTER key to change to Switching hour, set it and change to
Switching minute and to priority sequence
→
– sequence 000 means ‚Output release will be removed for all compres-
sors from the set time’.
– sequence 123 means: From the switching time onwards ‚Compressor
No. 1 takes the base load, Compressor No. 2 the middle load and
Compressor no. 3 the peak load.
– sequence 312 means: From the switching time onwards ‚Compressor
no. 3 takes the base load, Compressor no. 1 the middle load and Com-
pressor no. 2 the peak load.
4. Use ENTER key to assign the selected Priority sequence to this switch-
ing canal
→ the display of the next switching canal blinks (here ‚B’).
5. If all desired switching channels were parameterized the same way (and
the letter of the next canal blinks) you can leave the setting area of the
switching channel by holding down arrow key and pressing ENTER
key . After first parameterization (by setting the interval time to zero),
the display automatically changes to the area described in the section
Time, otherwise the display described in 9.) appears ,Pressure + Day +
Time’.
