10 ERRORS
10.1 Errors
CODE MEANING
Pr1 Cabinet probe error
Solutions:
• check that the probe is the NTC type
• check the integrity of the probe
• check the instrument-probe connection
• verify the temperature of the cabinet
Main consequences:
• the activity of the compressor will depend on parameters
C4 and C5
• defrosting will never be activated
• the alarm output will be activated (only if parameter u1
and/or parameter u11 is set at 3)
• the door heaters will be switched-off (only if parameter u1
and/or parameter u11 is set at 4)
• the evaporator valve will be deactivated (only if
parameter u1 and/or parameter u11 is set at 5)
Pr2 Evaporator probe error
Solutions:
• the same as the previous case but relative to the evaporator
probe
Main consequences:
• if parameter P3 is set at 1, defrosting will last for the time
established with parameter d3
• if parameter P3 is set at 1 and parameter d8 is set at 2 or 3,
the instrument will function as if parameter d8 is set at 0
• if parameter F0 is set at 3 or 4, the instrument will function
as if parameter is set at 2
• the alarm output will be activated (only if parameter u1
and/or parameter u11 is set at 3)
Pr3 Condenser probe error
Solutions:
• the same as the previous case but relative to the condenser
probe
Main consequences:
• the overheated condenser alarm (“COH” code) will
never be activated
• the compressor blocked due to condenser temperature
alarm (“CSd” code) will never be activated
• the alarm output will be activated (only if parameter u1
and/or parameter u11 is set at 3)
• if parameter u1 and/or parameter u11 is set at 6, the
condenser fan will function in parallel to the compressor
rtc Clock error
Solutions:
• set the day and real time again
Main consequences:
• if parameter d8 is set at 4, the instrument will function as
if parameter is set at 0
• the HACCP function will not supply information relative
to the date and time the alarm occurred
• the Energy Saving function will not be available in real
time
• the alarm output will be activated (only if parameter u1
and/or parameter u11 is set at 3)
ErC Error of compatibility user interface-control module
Solutions:
• check the compatibility user interface-control module
(check the data related in the labels)
Main consequences:
• the control module will keep working correctly
ErL Error of communication user interface-control module
Solutions:
• check the connection user interface-control module
Main consequences:
• the control module will keep working correctly
When the cause of the alarm disappears, the instrument restores normal
functioning, except for the clock error (“rtc” code) that requires setting
of the day and real time.

TECHNICAL DATA
11.1 Technical data
User interface container: open frame board behind a methacrylate
sheet.
Control module container: open frame board.
User interface protection rating (front): IP 65.
Control module protection rating: IP 00.
User interface connections: screw terminal board (at the control
module).
The user interface connects to the control module via a 4-way cable:
the maximum length allowed for the connection cable is 20 m
(65.614 ft; the cable is not supplied with the instrument).
Control module connections: 6.3 mm faston (0.248 in, power
supply and outputs), screw terminal board (to the user interface and
inputs), 6-pole connector (serial port).
Temperature of use: from 0 to 55 °C (from 32 to 131 °F, 10 ... 90%
relative humidity without condensate).
User interface power supply: the user interface is powered by the
control module.
Control module power supply: 115 ... 230 VCA, 50/60 Hz, 10 VA.
Maintaining the clock data in a power cut: 24 h with battery
charged.
Battery charging time: 2 min without interruptions (the battery is
charged by the instrument power supply).
Alarm buzzer: incorporated (in the user interface).
Measurement inputs: 3 (cabinet probe, evaporator probe and
condenser probe) for NTC probes
Digital inputs: 2 (door micro switch and multipurpose) for normally
open/normally closed contact (potential free contact, 5 V 1 mA).
Range of measurement: from -40 to 105 °C (from 40 to 220 °F).
Resolution: 0.1 °C/1 °C/1 °F.
Digital outputs: 4 relays:
• compressor relay: 30 A res. @ 250 VCA (NO
contact)
• defrosting relay: 16 A res. @ 250 VCA (contact
in exchange)
• evaporator fan relay: 8 A res. @ 250 VCA (NO
contact)
• fourth output relay: 16 A res. @ 250 VCA (NO
contact))
• fifth output relay: 8 A res. @ 250 VCA (contact
in exchange).
The maximum current allowed on the loads is 20 A.
Serial port: port for communication with the Parameters Manager
set-up software system or to the monitoring and supervision system of
RICS plants (via TTL, with MODBUS communication protocol) or with
the EVKEY programming key.
