* 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.
