PRELIMINARY INFORMATIONS
After derived the connections related in Fig. 6, during the normal functioning the instrument displays the temperature read by the cabinet probe.
iu3195.wmf
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 3-195 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 1 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.
The output K 2 is associated to the evaporator fans and it is forced to the status ON, except what established with the parameters of the family F.
If the instrument was set to manage defrost interval count passed the defrost interval, if the conditions permit it (the temperature read by the evaporator probe must be below the defrost stopping setpoint) the instrument automatically presents a request of a defrost cycle, if the instrument was set to manage real time defrost the instrument automatically presents a re­quest of a defrost cycle at every time established with the parameters of the family Hd, accord­ing with the real hour and minute established with the label rtc.
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 3 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.
To the time established with the parameters of the family Hr, according with the real hour and minute established with the label rtc, the instrument activates an Energy Saving cycle; during an Energy Saving cycle the compressor output is associated to the auxiliary setpoint, it re­mains activated continuously as long as the temperature read by the cabinet probe reaches the auxiliary setpoint and when it rises above the auxiliary setpoint of the hysteresis value (differ­ential) the output gets reactivated, except during a defrost and a dripping.

WORKING SETPOINT
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 r 1 and r 2
- if the parameter r 5 has value 1 the working setpoint can not be modified as long as the parameter r 5 gets set to 0
- the working setpoint value gets stored in a non volatile memory even if a lack of power supply happens.

SIGNALS
If the LED L1 is turned ON it means that the compressor output is activated. If the LED L2 is turned ON it means that the defrost output is activated. If the LED L3 is turned ON it means that the evaporator fans output is activated. If the LED L1 flashes it means that a count of a disabling time to the compressor output activa-
tion is running (see the parameters C 0, C 1, C 2 and C 4). If the LED L2 flashes it means that a count of a delay time to a defrost cycle activation is
running (see the parameters C 0, C 1, C 2 and C 4), that a dripping is running (see the param­eter d 7).
If the LED L3 flashes it means that an evaporator fans stoppage is running (see the parameter F 5).
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 setting and using procedures is refused, all outputs get forced to the status OFF.
If the instrument displays the indication “E0” flashing alternated to the indication “---” and the buzzer utters an intermittent beep (cabinet probe failure alarm) it means that: the kind of connected cabinet probe is not proper (see the parameter / 0), the cabinet probe is faulty (verify

the cabinet probe integrity), there is a mistake in the instrument-cabinet probe connection (verify the instrument-cabinet probe connection integrity), the temperature read by the cabinet probe is outside the limits permitted by the cabinet probe in use (verify that the temperature near the cabinet probe be inside the limits permitted by the cabinet probe); during this alarm the compressor output functioning gets established with the parameters C 5 and C 6, if a defrost cycle is running the defrost cycle ends and the instrument never activates a defrost cycle.
If the instrument displays the indication “E1” flashing alternated to the temperature read by the cabinet probe and the buzzer utters an intermittent 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 F 7 has value 3 or 4 the evaporator fans output gets forced to the same status of the compressor output, except what established with the param­eters F 4 and F 5 and the defrost ends passed the defrost maximum length.
If the instrument displays the indication “Ain” flashing alternated to 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 i 0 and i 1); during this alarm gets given the action established with the parameter i 0.
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 i 0 and i 1); during this alarm gets given the action established with the parameter i 0.
If the instrument displays the indication “AH” flashing alternated to the temperature read by the cabinet probe and the buzzer utters an intermittent beep (upper temperature alarm) it means that the temperature read by the cabinet probe is outside the limit established with the parameter Ab1 (see the parameters A 0, A1b and A2b); inactive.
If the instrument displays the indication “AH” flashing, the temperature read by the cabinet probe flashing every three seconds and the buzzer utters an intermittent beep (stored tem- perature during an upper temperature alarm) it means that there was an upper temperature alarm (see the parameters A 0, A1b, A2b, A 8 and A 9); inactive, to display and to erase the temperature read by the cabinet probe stored during an upper temperature alarm see the chap­ter ADDITIONAL FUNCTIONS.
If the instrument displays the indication “AL” flashing alternated to the temperature read by the cabinet probe and the buzzer utters an intermittent beep (lower temperature alarm) it means that the temperature read by the cabinet probe is outside the limit established with the param­eter AbA (see the parameters A 0, A1A and A2A); inactive.
If the instrument displays the indication “AL” flashing, the temperature read by the cabinet probe flashing every three seconds and the buzzer utters an intermittent beep (stored tem- perature during a lower temperature alarm) it means that there was a lower temperature alarm (see the parameters A 0, A1A, A2A, A 8 and A 9); inactive, to display and to erase the temperature read by the cabinet probe stored during a lower temperature alarm see the chapter ADDITIONAL FUNCTIONS.
If the instrument displays the indication “rtc” flashing and the buzzer utters an intermittent beep (“Real Time Clock” failure) it means that there is a corruption of the instrument clock data (set the real hour and minute again: if to the turning ON again the alarm does not disap­pear the instrument must be replaced); during this alarm, if the parameter d E has value 3 the instrument manages periodicals defrost interval and the instrument never activates an Energy Saving cycle.
