27/54
don
Time delay between the insertion of two different compressors
(0 - 99.5 min; res. 10 s).
doF
T
ime delay between switching off of two different compressors
(0 - 99.5 min; res. 10 s)
donF Minimum time a stage stays switched ON
(0 - 99.5 min; res. 10 s)
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 - 255 s) 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 the
P3, 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. 3 - 4)
P4:
probe P4 (term. 22 - 23)
17.7 Fans regulation
Pb
Proportional band zone width
(0.10 - 5.00 bar; 0.5 – 30 °C or 1 – 80 PSI; 1 – 50 °F).
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 – 20 bar; -50 – 50 °C) this value is added to the fans
set point.
PbES Band offset for fan regulation in ES
(-50.0 - 50.0°C; -90 - 90°F; -20.0 - 20.0 bar;
-300 – 300 PSI; -2000 – 2000 kPA). During energy saving
Fon
Time delay between the insertion of two different fans
(0 - 255 s).
FoF
T
ime delay between switching off of two different compressors
(0 – 255 s)
LSF
Minimum set point for fan
: 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.
HSF
Maximum set point for fan
: The measurement unit depends on dEU parameter. It sets
the maximum acceptable value for set point.
