PRELIMINARY INFORMATIONS

After derived the connections related in Fig. 5, the instrument reproposes the last settings
stored.

iu6294.wmf

Keeping pushed for two seconds at least the key T4 the instrument turning ON (status ON) or
turning OFF (status STAND-BY), except during the working setpoint setting and the configura­tion parameters setting procedures; the LED L4 is associated to the instrument status, it is
turned ON during the status STAND-BY and it is turned OFF during the status ON.

During the status STAND-BY the display is turned OFF and all outputs are forced to the status
OFF.

During the status ON, in the course of the normal functioning the instrument displays the
temperature read by the cabinet probe: if an alarm should be active the instrument displays the
alarm code flashing and the buzzer utters an intermittent beep as long as the cause that has
given it does not disappear (see the chapter SIGNALS AND ALARMS); pressure on the key T1
during an alarm permits to silence the buzzer.

EC 6-294 is provided with one working setpoint and with some configuration parameters that
get stored in a non volatile memory and that permit to set the instrument according with one’s
requirements (see the chapter CONFIGURABILITY).

The output K 1A is associated to the compressor and to the working setpoint, it remains
activated continuously as long as the temperature read by the cabinet probe reaches the work­ing setpoint and when it rises above the working setpoint of the hysteresis value (differential)
the output gets reactivated, except during a defrost and a dripping.

Passed the defrost interval from the moment of the instrument start or from the moment in
which the instrument presents a request of a defrost cycle, if the conditions permit it (the
temperature read by the evaporator probe must be below the defrost stopping setpoint) the
instrument automatically presents the following request of a defrost cycle.

A defrost cycle provides three phases (defrost, dripping and evaporator fans stoppage) con­nected in cascade since the end of one automatically determines the passage to the following
one.

The output K 2A is associated to the defrost and it remains continuously activated during the
defrost as long as the temperature read by the evaporator probe reaches the defrost stopping
setpoint when the defrost ends and the instrument automatically moves to the dripping; if the
instrument was set to manage defrost to resistances (electrical) during a defrost the compres­sor output gets forced to the status OFF, if the instrument was set to manage hot gas defrost
(reversal of cycle) during a defrost the compressor output remains continuously activated.

Passed the dripping length from the moment of the defrost end the instrument automatically
moves to the evaporator fans stoppage; during a dripping the compressor output gets forced
to the status OFF.

Passed the evaporator fans stoppage length from the moment of the dripping end the defrost
cycle ends; during an evaporator fans stoppage the evaporator fans output activation gets
disabled.

If the conditions permit it (the temperature read by the evaporator probe must be below the
defrost stopping setpoint) keeping pushed the key T2 for four seconds at least the instrument
presents a request of a defrost cycle.

The output K 3A is associated to the cabinet light: pushing and releasing the key T5 the output

gets activated or deactivated, except during the working setpoint setting and the configuration
parameters setting procedures; the LED L5 is associated to the output status, it is turned ON
when the output is activated and it is turned OFF when the output is deactivated.

The output K 4A is associated to the evaporator fans and to the output deactivation setpoint, it
remains continuously activated as long as the temperature read by the evaporator probe reaches
the output deactivation setpoint, when it falls below the output deactivation setpoint of the
hysteresis value (differential) the output gets reactivated and during the status OFF of the
compressor output the output gets forced to the status OFF, except what established with the
parameters of the family F.

The output K 5A is associated to the instrument status: it is forced to the status ON during the
status ON and it is forced to the status OFF during the status STAND-BY.

Activating the multifunction digital input and the locking digital input (available on request
instead of a relay output) the instrument interacts on the outputs activity according what
established with the parameters of the family i.

WORKING SETPOINT SETTING (WORKING TEMPERATURE)

To modify the working setpoint value keep pushed the key T3 (the instrument displays the
actual value) and at the same time push and release over and over the key T1 or T2 as long as
the instrument displays the desired value (keeping pushed the key T1 or T2 the value gets
decreased or increased more quickly): after the modification release the key T3 last; during the
pressure of the key T3 the LED L1 flashes quickly to indicate that a working setpoint setting
procedure is running (to the release of the key T3 the instrument automatically turns out from
the working setpoint setting procedure).

ADDITIONAL INFORMATIONS

- for the whole period of a corrupted memory data alarm the access to the working
setpoint setting procedure is refused

- the working setpoint is programmable within the limits established with the param­eters r1 and r2

- the working setpoint value gets stored in a non volatile memory even if a lack of
power supply happens.

CONFIGURATION PARAMETERS SETTING

Configuration parameters are arranged on two levels, to protect the most tricky settings against
undesirable violations and they are arranged in families that can be recognized through the
initial letter of the label.

To gain access to the first level keep pushed at the same time for four seconds at least the keys
T1 and T2 (passed four seconds the instrument displays the label PA).

To select a parameter of the first level push and release over and over the key T1 or T2 as long
as the instrument displays the label of the desired parameter.

To modify the parameter value keep pushed the key T3 (the instrument displays the actual
value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets de­creased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).

To gain access to the second level enter inside the first level and select the label PA.
Keep pushed the key T3 (the instrument displays the actual value) and at the same time push

and release over and over the key T1 or T2 as long as the instrument displays -19 (keeping
pushed the key T1 or T2 the value gets decreased or increased more quickly): after the modi­fication release the key T3 last (to the release of the key T3 the instrument displays the label PA
again); keep pushed at the same time for four seconds at least the keys T1 and T2 (passed four
seconds the instrument displays the first parameter of the second level).

To select a parameter of the second level push and release over and over the key T1 or T2 as
long as the instrument displays the label of the desired parameter.

To modify the parameter value keep pushed the key T3 (the instrument displays the actual
value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets de­creased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).

To turn out from the configuration parameters setting procedure keep pushed at the same time
for four seconds at least the keys T1 and T2 or do not operate with the keys for fifty seconds
at least (time-out exit).

ADDITIONAL INFORMATIONS

- for the whole period of a corrupted memory data alarm the access to the configura­tion parameters setting procedure is refused

- the modification of the parameter /A value has not immediate effect; to obtain this
effect, after the modification turn OFF and turn ON again the instrument

- the modification of a parameter value which unit of measure is the hour or the
minute or the second has not immediate effect; to obtain this effect it must not be
executed during the course of the value

- the modification of the parameters u1, u2, u3, u4 and u5 value has immediate ef­fect; to avoid damages to the connected users, it must be executed during the
status STAND-BY

- the configuration parameters values get stored in a non volatile memory even if a
lack of power supply happens.

PRELIMINARY INFORMATIONS

On request the instrument can be preset to work in a serial network of instruments (slaves)
managed from a master instrument in order to implement some resources in the slaves instru­ments in correspondence with the implementation of the same resources in the master instru­ment (compressor output status during the normal functioning, presentation of a request of a
defrost cycle, etc.).

After derived the connections related in Fig. 5, the master instrument reproposes the last
settings stored (see the chapter USE), the resources management of the slaves instruments
locally happens (see the chapter USE), except what established with the parameters of the
family n.

ALARMS

If the instrument displays the indication “E2” flashing and the buzzer utters an intermittent
beep (corrupted memory data alarm) it means that there is a corruption of the configuration
data in the memory (turn OFF and turn ON again the instrument: if to the turning ON again the
alarm does not disappear the instrument must be replaced); during this alarm the access to
the working setpoint setting and the configuration parameters setting procedures is refused,
all outputs get forced to the status OFF and if the instrument is set as master instrument the
resources management of the slave instrument locally happens.

If the instrument displays the indication “E3” flashing and the buzzer utters an intermittent
beep (instrument locking) it means that there was a number of locking digital input alarm
enough to give the instrument locking (turn OFF and turn ON again the instrument, see the
parameters i2, i3, i4 and i5); during this alarm the compressor output gets forced to the status
OFF, if a defrost cycle is running the defrost cycle ends and the instrument never activates a
defrost cycle.

beep (evaporator probe failure alarm) it means that there is one of the faults saw in the
previous case but referred to the evaporator probe; during this alarm, if the parameter F7 has
value 3 or 4 the evaporator fans output gets forced to the same status of the compressor
output, except what established with the parameter F5 and the defrost ends passed the defrost
maximum length.

If the instrument displays the temperature read by the cabinet probe and the buzzer utters an
intermittent beep (multifunction digital input alarm) it means that the multifunction digital
input is active (deactivate the multifunction digital input, see the parameters i0 and i1); during
