Pressure transmitter’s working range
Depending on the pressure, a pressure transmitter with a given working range is
used. This working range must be set in the controller (e.g.: -1 to 12 bar
The values must be set in bar if display in °C has been selected. And in psig, if °F has
been selected.
If the values are to be set from the
AKM programme, they must be set in
bar.

Operating hours
The operating hours for the compressor relays can be read and set in the follow-
ing menus. The read value is multiplied by 1000 to obtain the number of hours (f.ex.
shows 2.1 for 2100 hours). On reaching 99.9 hours the counter stops and must now be
reset to, say, 0. There will be no alarm or error message for counter overow.
(In the AKM display the hour number
has not been multiplied)
Value for relay number 1 to 4 o23-
o26

Refrigerant setting
Before refrigeration is started, the refrigeration must be dened. You may choose
between the following refrigerants:
1=R12. 2=R22. 3=R134a. 4=R502. 5=R717. 6=R13. 7=R13b1. 8=R23. 9=R500.
10=R503. 11=R114. 12=R142b. 13=User dened. 14=R32. 15=R227. 16=R401A.
17=R507. 18=R402A. 19=R404A. 20=R407C. 21=R407A. 22=R407B. 23=R410A.
24=R170. 25=R290. 26=R600. 27=R600a. 28=R744. 29=R1270. 30=R417A.
31=R422A, 32=R413A. 33=R422D. 34=R427A. 35=R438A.
Warning: Wrong selection of refrigerant may cause damage to the compressor.
Other refrigerants: Select setting 13 here, and subsequently three factors have to be
set – fac1, fac2 and fac3 – via AKM.

Manual control (stopped regulation only)
From this menu the relays can be cut in and out manually. 0 gives no override, but a
number between 1 and 10 will cut in a belonging relay. 1 will cut in relay number 1, 2
relay 2, etc.
11-18 will produce voltage on the analog output. In this way the relays on the exter-
nal relay module can be activated. Setting 11 will give a voltage of 1.25 V, setting 12
will give 2.5 V, etc.

Frequency
Set the net frequency.
