8.3 Parameters concerning inputs
C13: Type of probes
C13 defines the type of electrical signal and the type of value measured by the probes.
Access:
Keypad: if C50=1, 3 or 4 Ü + for 5” and password 77;
if C50=0 or 2 Ü the parameter can only be displayed.
Remote control: if C50=4 Ü press “ENABLE” and and ;
Operating range: 0 for FCM00NTC00, 1 to 2 for FCM0001000, 3 to 7 for FCM0002000.
C13=0 Ü NTC probes (10 kΩ at 25°C)
C13=1 Ü 0÷10 V probes for temperature or humidity
C13=2 Ü 0÷10 V probes for pressure
C13=3 Ü 0÷20 mA probes for temperature or humidity
C13=4 Ü 0÷20 mA probes for pressure
C13=5 Ü 4÷20 mA probes for temperature or humidity
C13=6 Ü 4÷20 mA probes for pressure
C13=7 Ü CAREL 4÷20 mA probes for temperature or humidity
Default: C13 = 0 for FCM00NTC00, 1 for FCM0001000, 6 for FCM0002000.
Note: CAREL 4÷20 mA probes are connected according to the figures on page XXX, since it is expected
a 100Ω maximum load value resistance.
C14: Type of refrigerant
C14 defines the type of refrigerant. If your system includes pressure probes, the knowledge of the type of refrigerant allows you to convert
pressure into temperature.
Access:
Keypad: if C50=1, 3 or 4 Ü + for 5” and password 77;
if C50=0 or 2 Ü the parameter can only be displayed.
Remote control: if C50=4 Ü press “ENABLE” and and ;
Modes: in all modes except C00=0 and 1 (“SLAVE DIRECT” and “SLAVE REVERSE” )
Other parameters: depends on C13=2, 4 and 6 (pressure probes).
Operating range: from 0 to 7
C14=0 Ü unspecified refrigerant
C14=1 Ü R22
C14=2 Ü R404a
C14=3 Ü R407
C14=4 Ü R134a
C14=5 Ü R410a
C14=6 Ü R290 (propane)
C14=7 Ü NH
3
(ammonia)
Default: C14 = 0 unspecified refrigerant
Not Available in FCM00NTC00.
Note: if the type of refrigerant is not specified, all the parameters concerning the measured variable will appear in bar. If the type of
refrigerant is specified, the pressure reading will be automatically converted into temperature and displayed on the basis of the unit of
measure as defined by C18.
C15: Minimum value of current or voltage inputs
C15 is the value measured when the input is given the min. possible signal, that is 0 V when using 0÷10 V probes, 0mA with 0÷20 mA
probes or 4 mA with 4÷20 mA probes.
Access:
Keypad: if C50=1, 3 or 4 Ü + for 5” and password 77;
if C50=0 or 2 Ü the parameter can only be displayed.
Remote control: if C50=4 Ü press “ENABLE” and and ;
Modes: in all modes except C00=0 and (“SLAVE DIRECT” and “SLAVE REVERSE” )
Operating range: from -40 to C16 for temperature probes in °C (C18=0) or °F (C18=1);
from 0.0 to C16 for humidity probes in rH (C18=2) or pressure probes in bar.
Default: C15 = 0.0
Not Available in FCM00NTC00.
