a. If required, set a relay to drive the invert (is used to signal to the inverter to start and stop the
regulation), by setting: oA(i) = inF inverter for fans
b. Set the kind of signal of the analog output current (4-20ma) or voltage (0-10V) by the
Analog output setting parameter “AoC”: tEn = 0÷10V output; cUr = 4-20mA output
c. Set the function of the analog output: AoF = InF
d. Set the time of the analog output at max after start up EI: Aot = 3s
e. Set the max % variation per min (MP)
f. At last set also the percentage of analog output in case of probe failure: (0 ÷ 100%)SAO
21.2 Analog output “free”
This setting is used to link the analog output 1 to a temperature probe. The analog output will take
values proportional to the temperatures detected by the probe P3 or P4, according to the setting.
21.2.1 Analog output “free” configurations and Parameters
Set the output to drive for instance a de-
superheater
Reference probe for the
analog output 1 (used only if
AOP=FrE)
It’s possible to set only P3 or P4 probes.
P3 must be set as temperature probe:
P3C = nt10 (NTC 10K) or nt86 (NTC 86K)
Temperature value
associated to minimum value
of analog output AOM.
It’s the start scale of the analog output
Temperature value
associated to the maximum
value of analog output (10V)
It’s the end scale of the analog output
Minimum value for analog
output
The minimum voltage is 0V.
NOTE: verify on the inverter of ECI fan of
chopped phase driver that with this input a
proper output is supplied to the fan.
