ALL Minimum temperature alarm: (1÷50°C/1°F) When the “SET-ALL”
temperature is reached the alarm is enabled, (possibly after the “Ald”
delay time).
ALd Temperature alarm delay: (0÷255 min) time interval between the
detection of an alarm condition and alarm signalling.
EdA Temperature alarm delay at the end of defrost: (0 ÷ 255 min) Time
interval between the detection of the temperature alarm condition at the
end of defrost and alarm signalling.
tbA Silencing alarm relay: (Yes= silencing buzzer and alarm relay, no= only
buzzer silencing).
OTHER
Ad1 Address 1 for RS485: (0 ÷ 94)
Ad2 Address 2 for RS485 (0 ÷ 94)
LodLocal display: (rP, EP, iP, nr) select which probe is displayed by the
instrument: rP: thermostat probe; EP: evaporator probe; iP: insert probe,
nr: during a temperature cycle the insert probe is displayed, during the
holding phase the room probe is displayed; if the cycle is made by time
the time remaining is displayed (in minutes).
rEd Remote display: (rP, EP, Ip) select which probe is displayed by the XR
REP. rP: thermostat probe; EP: evaporator probe; iP: insert probe.
LocSet point of the holding phase lock (no - YES) It locks the set point of
the holding phase.
PAS Security code set up: (0 ÷ 999) It sets the personal security code.
tPb Type of probe: it displays the probe used (NTC or PTC) (readable only)
rEL Release code (readable only)
Ptb Parameter code (readable only)

18. Printer management
The instrument XB570L can drive the serial printer XB05PR by means of
the RS232 output. So temperatures measured during a freezing cycle can be
printed. Time reference is provided by the internal Real Time clock of the
instrument.
The “Prt” functions manages the printer by means of the following
parameters:
Prt: printer presence: (Yes/no) it enables or disables the printer.
itP: printing interval: (0.0÷30.0 min).
PbP: which probe has to be printed: (iP: Only the insert probe; rP: Only
the thermostat probe; irP: Insert and thermostat probes; irE: All the probes.
PtH: Printing during the holding phase (yES, no) yES = Printing enabled
during the holding phase; no= Printing disabled during the holding phase.
19. IV configurable relay.
The relay can be used for
19.1.1 OAC=AL: for remote alarm
the IV relay is switched ON when an alarm happens.
19.1.2 OAC=Li: light
The light is switched on pressing the DOWN key or when the door is opened
(if dIC=dor). It stays on for the OAt time. It can be switched off before the OAt
time by pressing the DOWN key or by closing the door. NOTE: with OAt=0 it
can be switched off only by pressing the DOWN key or by closing the door.
19.1.3 OAC=UL: UV light for a sterilisation cycle
It is used for a sterilisation cycle of the machine.
It can be enabled ONLY WHEN THE CONTROLLER IS NOT WORKING or
when a manual defrost is running.
The ultra violet light stays on for the OAt time. It can be switched off before
the OAt time by pressing the DOWN key.
NOTE: with OAt=0 it can be switched off only by pressing the DOWN key.
19.1.4 OAC=AA: to enable the resistor of anti condensation
It can be enabled by pressing the DOWN key. The resistor stays on for the
OAt time. It can be switched off before the OAt time by pressing the DOWN
key.
NOTE: with OAt=0 it can be switched off only by pressing the DOWN key.
19.1.5 OAC=iP to extract the insert probe by means of a resistor
heater
It can be enabled ONLY WHEN THE CONTROLLER IS NOT WORKING. To
extract the insert probe press the DOWN key for few seconds. The resistor
stays on for the OAt time. To switch it OFF before the OAt time, press the
DOWN key for few seconds. NOTE: with OAt=0 it can be switched off only by
pressing the DOWN key.
19.1.6 OAC=rE thermostat function
The IV relay works like a thermostat with the set point OAS and the
differential OAH. The kind of action is selectable by means of the OAH
parameter: with OAH<0, the action is for heating, with OAH>0 it is for
cooling. In this case the probe used for the regulation is selected by means
of the OAi parameter.
E.G. with OAi = rP; OAH>0
19.1.7 OAC = C2: as second compressor.
Second compressor operates on the following set: 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:
Cycle
Holding
1c2=0
C1 ON; C2 On C1 on; C2 On
1c2=1
C1 on; C2 On C1 on C2 off
1c2=2
C1 on; C2 off C1 on; C2 On
1c2=3
C1 on; C2 off C1 off; C2 On
20. Digital configurable input.
The configurable input has 3 functions, selectable by means of the dIC
parameter
• dIC=EAL Signal a external alarm (after the dId time): buzzer enabled,
“EA” message on the display.
• dIC=bAL Signal a external serious alarm(after the dId time): buzzer
enabled, all the loads are switched OFF and the cycle is stopped, “CA”
message on the display. When the alarm recovers the controller is
placed in stand by mode.
• diC=dor: “door switch” input: the compressor and the fans are
stopped; if OAC=Li the light is switched on; after the dId time the buzzer
is enabled and the dA message is displayed.
