General S.V. start/stop key
This key (ref. E) allows the solenoid valves to be stopped or restarted simultaneously.
As for the previous key, also for this function, the progress of the bright LED
corresponding to the key must be considered.
If the LED is ON it means "STOP" and both solenoid valves must be de-energised. If
the LED is off, the opposite occurs.
N.B. Only the "full opt." art. 4494 MCK 2200 model has an output available for a general
valve that is activated only if both the other two solenoid valves of the sections are de-
energised. This allows the direct discharge into the tank when not working with the
sections open.

Programming
The "PROGRAMMING" section, carried out with the keys ref. H, L and M, allows the
computer to be adapted to the machine by setting some constants described in the
following paragraph.
N.B. Only in the case of the "full opt" art. 4494 MCK 2200 model and during work (out
of the programming mode), can an output be controlled by using the keys (ref. M) and
– (ref. L) to adjust the electric pressure valve.

Set the flowmeter pulses/litre indicated by the flowmeter in the constant "i".
Set the maximum value of the working range of the pressure sensor in the constant
"Pr".
If the "distributed litres" and "working pressure" data calculated by the computer are
not consistent with the real ones, they can be corrected by modifying the value of the
relevant constants.
