PRESET PROGRAMS (Bootstrap)

At delivery this processor is programmed with the following (variable) settings.
To return to these settings at any time.
Power off the processor, press ALARM MAX key and keep it pressed giving
power on: release ALARM MAX key when on the screen boot message
appears. t.SEt = 25.0° AL _ _ = 10.0° AL - - = 30.0°

The COSt values are shown in COSt Programming.

Press + : will be displayed followed by

°Maximum Temperature Recording.

Press - : will be displayed followed by

°Minimum Temperature Recording.

VIEWING TEMPERATURE RECORDING

Values recorder are memory permanent stored: for memory clear keep pushed + keys
for more than 3 seconds: CLEA message will be composed on display before clearing
operation.

MAIN SETTING (Run Mode)

TEMPERATURE SETTING

Press TEMP (key lamp flashes): this message will be displayed
instead of the ° Set temperature value.
Press + or - to modify, press SET to escape.

MINIMUM ALARM TEMPERATURE

Press MIN ALARM (key lamp flashes): this message will be
displayed instead of the ° Set Minimum temperature value .
Press + or - to modify (*), press ALARM MIN to escape.

TEMPERATURE SETTING

Press MAX ALARM (key lamp flashes): this message will be
displayed instead of the ° Set Maximum temperature value.
Press + or - to modify (*), press ALARM MAX to escape.

* If option o.ALA=1 (see COSt) the c.AL_ or c.AL- message appears on display.
If option o.ALA=2 (see COSt) the r.AL_ or r.AL- message appears on display.

How to connect the sensors
Connect the sensor provided as shown in the diagram. For remote connections
use a standard 0.5-square millimeter two-pole wire, taking great care over the

connections, by insulating and sealing the joins carefully. -O.C.- is displayed when the
temperature sensor wiring is open, -S.C.- is displayed when the temperature sensor
wiring is short circuit.

COSt PROGRAMMING (System constants)

These settings refer to the mode operation of the system and must be made
These settings refer to the operation mode of the system and must be made
on initial startup. Press - / + at the same time for at least one second: the
message C.O.S.t. will be displayed.

Press than repeatedly ALARM MAX until the message regarding the chosen
variable is displayed (see table below): variable’s value and message will be
displayed.
Press + or - to set a new value and then press ALARM MAX to confirm.
The next system constant will then appear.
You can press SET 2 for at least 2 seconds to exit and return to the Run Mode.

OPERATIVE DIAGRAMS

The light situayed at the bottom of the display show the state of the various relays as set out below:

STATE INDICATION LAMPS

*1) For more details see Operative Diagrams.
*2) o.ALA = 0 : Minimum and maximum alarm sets user settable (see ALARM keys).

*3) If o.ALA = 1 : Minimum or maximum absolute alarm set value.

If o.ALA = 2 : Minimum or maximum relative alarm set value.
For more details see Operative Diagrams.

*4) :=1 : °C Temperature range.

=2 : °F Temperature range.

*5) You can correct the readings on the various sensor (+ or -).

MANUAL MODE

In some start-up conditions may be useful to work in "hand" mode.
Power off the processor, press + key and keep it pressed giving power on:
HAnd message will be displayed (release now + key).
Push + until is displayed number required to be handed (see table relays "N°

Relay") and push ALARM MAX for activing relay.
Pushing again + for increase relay number previous relay is disactivated.
You can press ALARM MAX for a least two seconds to escape and return to the Run Mode.
