This menu is used for the management of the printer. It contains the

parameters:

PrP

printer presence: (Yes/no) Enabling or disabling the printer

itP: printing interval: (0.0÷30.0 min) It sets the interval of printing.

PbP: Which probe print: (,iP: Only the Insert probe; rP: Only the room

probe; irP: The Insert and the room probe; irE: All the probe)

16. Accessing "Pr2" and SECURITY CODE input

To access parameters in "Pr2" a security code is required.

Enter Function Menu, select label "Pr2" and press the "SET" key. The

"PAS" flashing message is displayed, shortly followed by "0 _ _" with a

flashing zero.

Use "UP" or "DOWN" to input the security code in the flashing digit;

Confirm the figure by pressing "SET".

Repeat operations 2 and 3 for the other digits.

If the security code is correct the access to "Pr2" is enabled by pressing

"SET" on the last digit, otherwise the "rtC" menu is shown.

If no key is pressed for more than 15 seconds the instrument reverts to room

temperature display mode.

The default SECURITY CODE is

NOTA1: the general security code is 981. (please refer to parameter PAS)

NOTE2: each parameter in "Pr2" can be removed or put into "Pr1" (user

level) by pressing "SET+ è". In Pr2 when a parameter is present in "Pr1" or

"rtC" LED

is on.

17. List of parameters

REGULATION

HyIntervention differential for set point: (0,1 ÷ 12,0 /0,1°C/1°F), always

positive. Compressor cut IN is Set Point Plus Differential (Hy).

Compressor cut OUT is when the temperature reaches the set point.

AC Anti-short cycle delay: (0÷30 min) minimum interval between the

compressor stop and the following restart.

1c2 Second compressor setting: (enabled only if OAC=C2)

The fourth relay work as second compressor if OAC=Co2.

Second compressor operates on set + OAS. (whit set= set loaded during

the current phase). It starts oAt min. after the first compressor

The following table shows how it works:

rPOThermostat probe calibration (-12,0 ÷ 12,0; res. 0,1 °C /1°F)

EPP Evaporator probe presence (not present in the XB350C): (no / YES)

no: not present (timed defrost); YES: present (end defrost )

EPO Evaporator probe calibration (not present in the XB350C): (-12,0 ÷

12,0; res. 0,1 °C /1°F)

iPP Insert probe presence (no / YES) no: not present; YES: present.

iPO Insert probe calibration (-12,0 ÷ 12,0; res. 0,1 °C /1°F)

CF Temperature measurement unit: °C =Celsius; °F =Fahrenheit

rES Resolution (for °C): in: integer; de: with decimal point

PAU Time of stand by: (0 ÷ 60min) after this time the controller restart the

cycle

PFt Maximum acceptable duration of power failure: (0 ÷ 250 min) if power

failure duration is less than PFt, the cycle restarts from the same point at

which it was stopped otherwise the cycle restarts from the beginning of

the current phase.

iPd Temperature difference for the automatic recognition of the insert

probe: (0 ÷ 30; ris.1 °C/1°F) if the difference of temperature between the

insert probe and the thermostat probe is less than iPd, the selected cycle

is made by time.

iPtTime delay for the automatic recognition of the insert probe:

(0÷255sec, with 0 only timed cycles are done) time between the start of

a cycle and the comparison of the temperature of the thermostat probe

and the insert probe to recognising if the insert probe is used.

Con Compressor ON time with faulty probe: (0÷ 255 min) time during

which the compressor is active in case of faulty thermostat probe. With

COn=0 compressor is always OFF

COF Compressor OFF time with faulty probe: (0÷255 min) time during

which the compressor is off in case of faulty thermostat probe. With

COF=0 compressor is always active

diC Digital input operating mode (EAL, bAL, dor)

EAL: external alarm; bAL: serious alarm; dor: door open function

diP: digital input polarity: (OP÷CL)select if the digital input is activated by

opening or closing the contact. OP= opening; CL=closing

did: digital input delay (0÷255 min) delay between digital input activation

and his signalling for configurable or door opened alarm.

NOTE: with diC=EAL did has to be different from zero.

OAC: AUX output configuration: (AL, Li, UL, Ip, AA, rE, dF, C2)

AL: alarm output; Li: light of the cabinet; UL: for the ultra-violet light (It is

actionable only when the controller is in OFF position); Ip: to extract the

insert probe (It is actionable only when the controller is in OFF position);

AA: anti - condensation; rE: the IV relay works as a thermostat, with

direct action (cooling) (OAH>0), and inverse actions (heating) (OAH<0);

dF: the IV relay is activated during the defrost, at the end of the defrost it

remains ON for the OAt time; C2: second compressor. See 1c2

parameter for different settings.

AUX output polarity (OP ÷ CL) OP= normally open; if it is ON the

OAP

terminals 6-8 are closed. CL= normally closed; if it is ON the terminals 6-

7 are closed.

OAt AUX output timer: (0÷255 min) time in which the AUX output stays ON.

It is enabled when OAC = Li or UL or Ip or AA or dF.

OAS Set point for AUX output (-50÷50; ris.1 °C/ 1°F)

OAH Differential for AUX output: (-12.0÷12,0; ris.0,1°C/1°F, always ≠0)

Intervention differential for the set point of the auxiliary, with OAH<0 the

action is for heating, with OAH>0 it is for cooling. COOLING: AUX cut IN

is OAS Plus Differential (OAH>0). AUX cut OUT is when the temperature

reaches the set point OAS.

HEATING: AUX cut IN is OAS Plus Differential (OAH<0). AUX cut OUT is

when the temperature reaches the set point OAS.

OAi Probe selection for the AUX output (rP, EP, iP) rP = thermostat probe,

EP = evaporator probe; iP = insert probe

tdF Defrost type (not present in the XB350C): (rE= electrical heater; in =

hot gas).

dPO Defrost before the holding: no= no defrost; YES= defrost at the start

of a holding cycle.

IdF Interval between defrost cycles: (0.1÷ 24.0; res. 10 min) Determines

the time interval between the beginning of two defrost cycles. (with 0.0

the defrost is disabled)

dtE Defrost termination temperature (not present in the XB350C): (-

50÷50 °C/°F) Sets the temperature measured by the evaporator probe,

which terminates the defrost.

MdF Maximum length for defrost: (0÷255 min) When EPP = no (timed

defrost) it sets the defrost duration, when EPP = YES (defrost

termination based on temperature) it sets the maximum length for

defrost.

dFd Temperature displayed during defrost: (rt , it, SEt, dEF) rt: real

temperature; it: temperature at the start of defrost; SEt: set point; dEF:

"dEF" message

Fdt Drip time (not present in the XB350C): (0 ÷ 60 min) Time interval

between reaching defrost termination temperature and the restoring of

the controllers' normal operation. This time allows the evaporator to

eliminate water drops that might have formed during defrost.

FnC Fans operating mode during the holding phase:

C-n= runs with the compressor, OFF during defrost; o-n = continuous

mode, OFF during defrost; C-Y = runs with the compressor, ON during

defrost; o-Y = continuous mode, ON during defrost;

FSt Fan stop temperature: (-50÷50°C/°F; res. 1°C/1°F) if the temperature,

detected by the evaporator probe is above FSt fans are stopped. It

serves to avoid blowing warm air around the room.

AFH Differential for the stop temperature and for the alarm (0.1 ÷ 25.0

°C; ris.0.1°C/1°F) Fans carry on working when the temperature reaches

the FSt-AFH value, the temperature alarm recovers when the

temperature is AFH degrees below the alarm set.

Fnd Fan delay after defrost: (0 ÷ 255 min) The time interval between end of

defrost and evaporator fans start.

ALU MAXIMUM temperature alarm: (1 ÷ 50 °C/°F) When the "SET+ALU"

temperature is reached the alarm is enabled, (possibly after the "Ald"

delay time).
