Counter of the nr of
temperature alarm
events occurred.
(being memorized data of
the latest temperature
alarm event, the counter
is boosted to know if
C 00 – C99
C##
previously other alarms
C -- = no alarms have been activated
occurred.
from the latest reset
This counter resets with
the memorized alarm
reset (silenced button +
SET for 5 seconds). It's
implemented at every
new temperature alarm).
DIAGNOSTICS
The display shows 'orH' for temperature out of range greater
than +99.9°C. It shows 'orL' for temperature out of range less
than -45.0°C.
In the case of faults, the "Expert nano" control unit informs the
operator by means of alarm codes shown on the display and an
acoustic signal emitted by the buzzer (if present). The acoustic alarm
can be stopped by pressing the UP key (the error code remains) and
can be reactivated by pressing the SET key. In the event of an alarm,
one of the following messages is displayed:
ALARM CODE TABLE
MEANING
Var
E0 Functional fault of ambient probe.
Functional fault of defrosting probe (in this case, any defrosting
Eu1
processes will have a duration equal to time d31).
Eu2 Functional fault of defrosting probe (in this case, any defrosting
processes will have a duration equal to time d32).
E2 EEPROM memory error. All outputs are deactivated except for
alarm outputs if present.
E8 Man-in-room alarm.
Compressor protection alarm (e.g. thermal protection or max.
Ec
pressure switch). All outputs are deactivated except for the alarm
output if present.
Door open alarm. When the door switch opens and the tdo time
Ed
has elapsed, normal function of the control is reset, triggering the
door open alarm (Ed).
EL Minimum temperature alarm. The letters EL flash alternating with
the temperature (see parameter A1).
EH Maximum temperature alarm. The letters EH flash alternating with
the temperature (see parameter A2).
E9 Room light alarm. The letters E9 flash alternating with the
temperature (see parameter Tdo).
E6 Discharged battery alarm; control function for at least another 20
days, then if there is not power to the time setting will be lost.
En Communication error between the ECHO display and the Master.

ELECTRICAL PRESCRIPTIONS
Avoid using multipolar cables with conductors connected to inductive and
power loads and signal conductors such as probes and digital inputs. Avoid
installing in the same channels power cables and signal cables (probes,
digital inputs or RS485 connections). Reduce to a minimum the length of
the connecting cables, avoiding that the cabling takes on a spiral form
which may have inductive effects on the electronic system. All conductors
used in the cabling must be appropriately sized in order to support the load
which they must provide. If it's necessary to extend the probes, use
conductors with appropriate cross-sections and not less than 1mm². The
extension or reduction of the probes may alter the calibration which was
performed in the factory. Therefore, verify and calibrate by means of an
external thermometer.
