* Installation.
On the connection diagram of the
ALFA 53-Grasso
you can see how the power supply,
network (to the sensor-pcb), contact input and relays have to be connected.
After connecting the
ALFA 53-Grasso
to the power supply, a self test function is started. As
this test is finished, the measured oil temperature appears in the display.
* Control.
The
ALFA 53-Grasso
alarm thermostat can be controlled by four pushbuttons on the front;
SET
- view / change cylinder temperatures.
UP
- increase a value and reset of alarm.
DOWN
- decrease a value.
MODE
- view status of relays.
* Viewing cylinder temperatures.
By pushing the
SET
key the first cylinder temperature sensor is selected and
‘S1'
appears
in the display to indicate this. By pushing the
MODE
key the actual value of this sensor in
viewed in the display.
You can select another cylinder temperature by pushing the
UP
and/or
DOWN
key. The
displays shows the according cylinder temperature number f.i. ‘S2', ‘S3'.
A few seconds after releasing the keys the cylinder temperature disappears and the
measured oil temperature is shown again in the display.
* Setting internal parameters.
Next to viewing the cylinder temperatures, some internal settings are possible like number
of cylinders, maximum cylinder temperature.
By pushing the
DOWN
key more than 10 seconds, you enter the 'internal programming
menu'. In the left display the upper and lower segment, are blinking. Over the
UP
and
DOWN
keys the required parameter can be selected (see parameters table). If the required
parameter is selected, the value can be read-out by pushing the
SET
key. Pushing the
UP
and/or
DOWN
key allows you to change the value of this parameter. If after 20 seconds no
key is pushed, the
ALFA 53-Grasso
changes to its normal operation mode.
