ERRORS

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.

(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:

contact)
•
defrosting relay:
16 A res. @ 250 VCA (contact
in exchange)
•
evaporator fan relay:

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.
