25/50
tMin
Maximum DGS functioning time at a capacity lower than MinP, before working at
full capacity (PMA)
(1÷255min)
tMAS Time of DGS functioning at maximum capacity (PMA) to restore the right
lubrication (
1÷255min)
ESC Energy saving value for compressors:
(-20÷20bar; -50÷50°C) this value is add to the
compressor set point.
onon
:
Minimum time between 2 following switching ON of the same compressor
(0÷255
min).
oFon
:
Minimum time between the switching off of a compressor and the following
switching on
. (0÷255min).
Note: usually onon is greater than oFon.
don
:
Time delay between the insertion of two different compressors
(0÷99.5min; res.
10s).
doF:
T
ime delay between switching off of two different compressors
(0÷99.5 min; res.
10s)
donF: Minimum time a stage stays switched ON
(0÷99.5 min; res. 10s)
Maon Maximum time for compressor ON
(0 ÷ 24 h; with 0 this function is disabled.) If a
compressor keeps staying on for the MAon time, it’s switched off and it can restart after
the oFon standard time.
FdLy
:
“don” delay enabled also for the first call.
If enabled, the triggering of the step is delayed
for a “don” value, respect to the call. (
no
= “don” not enabled;
yES
=”don” enabled)
FdLF
“
doF” delay enabled also for the first switching off
. It enables the “doF” delay between
the request of a release and the actual switching off. (
no
= “doF” not enabled;
yES
=”doF”
enabled)
odo
:
Regulation delay on start-up:
(0÷255s) on switching ON the instrument starts working
after the time delay imposed in this parameter.
LSE
:
Minimum set point
: The measurement unit depends on dEU parameter. It sets the
minimum value that can be used for the set point, to prevent the end user from setting
incorrect values.
HSE
:
Maximum set point
: The measurement unit depends on dEU parameter. It sets the
maximum acceptable value for set point.
17.6 Liquid injection thermostat
Lit
:
Set point ( °C) for cooling injection thermostat
(0 ÷ 150°C) The reference probe is set
by LiPr parameter, the thermostat relay is given by the relay set as
oAi = Lin.
Lid
:
Differential for cooling injection thermostat
(0.1 ÷ 10.0) The reference probe is set by
LiPr parameter
LiPr
Probe for cooling injection thermostat:
nP:
function disabled
P3:
probe P3 (term. 38-42)
P4:
probe P4 (term. 22-23)
17.7 Fans regulation
Pb
Proportional band zone width
(0.1÷30.0°C; 1÷50°F; 0.1÷10.0bar, 1÷150PSI;
10÷1000KPA).
NOTE: Set the dEU par. and the target set point for fans before setting this
parameter.
The band is symmetrical compared to the target set point, with extremes: SETF+Pb/2 ÷
SETF -Pb/2. The measurement unit depends on the dEU par.
ESF
Energy saving value for fans:
(-20÷20bar; -50÷50°C) this value is add to the fans set
point.
PbES Band offset for fan regulation in ES
(-50.0÷50.0°C; -90÷90°F; -20.0÷20.0bar; -
300÷300PSI; -2000÷2000KPA). During energy saving
