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.
