description
E1
4TH S.
Input for 4th speed request.
The speed is active when the pin is high, connected to +Batt.
E2
3RD S.
Input for 3rd speed request.
The speed is active when the pin is high, connected to +Batt.
E3
2ND S.
Input for 2nd speed request.
The speed is active when the pin is high, connected to +Batt.
E4
HYD. S.
Input for hydrodrive speed request.
The speed is active when the pin is high, connected to +Batt.
The programmable timing (HYDRO TIME) is associated to this input.
E5
1ST S.
Input for 1st speed request.
The speed is active when the pin is high, connected to +Batt.
E6
DOWN
Only input DOWN: function descent with proportional EV connected
to connectors PT and NEVP.
Input DOWN + Hydro: both functions are activated.
Input Down+ABP: function slow lifting. The value of parameter is
reduced in function of the parameter "VMN VALVE VOLTAGE" that
in this case has the following values:
Prog.
0
1
2
3
4
5
6
7
8
9
%pwm max.
2
4
8
10
15
20
25
30
40
50
In this case the function descent is not carried out.
N.B. for avoiding the activation descent is not when the lift request
comes off the slow lift microswitch must be cable in series with the
ABP microswitch.
E7
UP
Input for speed request handled by potentiometer, active high..
E8
HYD. S.
Same function as E4 but active when forced to -BATT.
E9
HYD. S
Like pin E8.
6.1.2 Programmable functions (OPTIONS)

1)
BATTERY CHECK
on
No low battery charge alarm.
off
Activates the check that reads the battery voltage in
standby. When the residual charge is less than 10%, all
functions are blocked except for the hydrodrive and the
LED blinks continuously.
