EV1 Output of the protected ON/OFF electrovalve driver; 1,5 A
maximum continuous current (driving to –Batt). Built-in
freewheeling diode to B2. This output is activated when
the 1ST function (input A12) is request.
EV3 Output of the protected ON/OFF electrovalve driver; 1,5 A
maximum continuous current (driving to –Batt). Built-in
freewheeling diode to B2. This output is activated when
the LIFT function (input A5) is request.
NAUX2 Auxiliary output. Internal 330R resistance in series to the
driver (driving to –Batt). Max continuous current: 35mA.
Typical function: to drive a led. If the BATTERY CHECK
option is different than zero, this output blinks with a 1
sec. period when the calculated battery charge is between
10% and 30%, and it stays on when the calculated battery
charge is < = 10%.
DI5 Input of the switch DI5. The input is activated when it is
connected to +Batt. The default function is the controller
"HORN" input, closing the switch the horn output is
activated.
DI7 Input of the switch DI7. The input is activated when it is
connected to +Batt. The default function is the controller
"LIFT" enable input.
DI9 Input of the switch DI9. The input is activated when the
external switch is opened. The default function is the
controller
pump speed is reduced.
DI11 Input of the switch DI11. The input is activated when the
external switch is opened to ground. The default function
is the controller "CUTBACK1" input, opening the switch
truck speed is reduced. In the Sense Coil version this
input is connected to the AC motor sense coil.
EV2 Output of the protected ON/OFF electrovalve driver; 1,5 A
maximum continuous current (driving to –Batt). Built-in
freewheeling diode to B2. This output is activated when
the 2ND function (input A13) is request.
NAUX1 Auxiliary output. Internal 330R resistance in series to the
driver (driving to –Batt). Max continuous current: 35mA.
Typical function: to drive a led. This output blinks with a
0.5 sec. period when a warning is displayed by the
controller. It is always ON when an important alarm is
displayed when no alarms are displayed, this output is
OFF.
"PUMP CUTBACK" input, opening the switch
