17.12 Dynamic set point for fan
dSEP Dynamic set point reference probe
nP
= no probe: dynamic set point disabled.
P3
= P3 probe
P4
= P4 probe
dSES External temperature value to start dynamic regulation
(-50 – 150 °C; -58 – 302 °F)
dSEb External band width for dynamic set point
(-50.0 - 50.0 °C; -90 – 90 °F)
dSEd Set point differential for dynamic set point: (
-20.0 - 20.0 °C; -50.0 - 50.0 PSI;
-300 – 300 °F)
17.13 Analog outputs (optional) - Terminals 23-34
AoC Analog output setting
tEn =
0 – 10 V output
cUr =
4 - 20 mA output
AOF Analog output function
nu
= analog output disabled.
Inc1
= not set it.
Inc2
= To drive inverter for suction frequency compressor, suction of circuit 2
inF
= to drive ECI fan or inverter for fan
FrE =
“Free”, proportional to the probe P3 and P4.
InCP Digital compressor always activated at first:
no:
other compressors if available are allowed to start when the inverter compressor is
locked by safety timers. This allows the system to satisfy the cooling demand when the
inverter compressor is unavailable.
yES:
the inverter compressor is always started as first. If unavailable due to safety timers
the regulation will be locked till timers will be over.
AOP Probe for analog output:
It is used only if AOP = FrE
nP
= no probe
P3
= Probe 4
P4
= Probe 3
LAO Temperature value associated to minimum value of analog output (AOM)
(-50.0 - 150.0 °C, -58 – 302 °F).
UAO Temperature value associated to the maximum value of analog output, 10 V or
20 mA
(-50.0 - 150.0 °C, -58 – 302 °F).
AOM Minimum value for analog output (
0 – 100 %)
AOt Time of analog output at max after the start (
0 - 15 s)
MPM Maximum % variation per minute:
(nu; 1 - 100)
nu =
not used: function disabled
1 - 100 =
it sets the maximum percentage variation per minute of the analog output.
SAO Percentage of analog output in case of probe failure:
(0 - 100 %)
AOH Maximum analog output percentage when silence mode function is enabled.
(0 - 100)
