rS Band offset
(-12.0 to 12.0°C / -21to21°F)
PI band offset. It moves the pro-
portional band of the PI. With
rS = 0, the band is between Set
to Set + Pb.
InC Integration time (0 to 255 sec)
PI integration time
PROBE PARAMETERS
tPP Type of pressure transducer (420 – 5V – LAn)
Sets the type of pressure transducer to use: 420 = 4 to 20mA pressure
transducer; 5V = 0 to 5V ratiometric transducer; LAn = the pressure sig-
nal comes from another XEV module.
LPP Enable pressure probe sending
in LAN
(n to Y)
If LPP = Y, the value of pressure read by device is sent in LAN. Only
one device of the LAN can have LPP = Y.
PA4 Probe value At 4mA or At 0V (-1.0 to P20 bar/ -14 to PSI)
Pressure value measured by probe at 4mA or at 0V (related to PrM pa-
rameter).
P20 Probe value 20mA or At 5V (PA4 to 50.0 bar/ 725 psi)
Pressure value measured by probe at 20mA or at 5V (related to PrM pa-
rameter).
OPr Pressure probe calibration (-12.0 to 12.0 bar/ -174 to 174 psi)
ttE Type of temperature probe (PtM to ntC)
Sets the kind of probe used by the controller: PtM = Pt1000, ntC = NTC
probe.
otE Temperature probe calibration (-12.0 to 12.0°C/ -21 to 21°F)
DIGITAL INPUTS
i1P Digital input 1 (free of voltage)
digital input polarity
(CL, OP)
CL = activated when closed; OP = activated when opened
i1F Digital input 1 (free of voltage)
digital input function
(CCL
, rL)
CCL = cooling call; rL = digital input activates relay
d1d Digital input 1 (free of voltage)
activation delay
(0 to 255 min)
This activation delay is used only if digital input is configured as rL.
i2P Digital input 2 (high voltage)
digital input polarity
(CL,OP)
CL = activated when closed; OP = activated when opened
i2F Digital input 2 (high voltage)
digital input function
(CCL, rL)
CCL = cooling call; rL = digital input activates relay
d2d Digital input 2 (high voltage)
activation delay
(0 to 255 min)
This activation delay is used only if digital input is configured as rL.
ALARM
dAo Alarm delay after restarting reg-
ulation
(0.0 to 42.0 min: tens of seconds)
Time between digital input activation (configured as CCL) and alarm
signaling. The LSH alarm is always signaled also during this time.
