Description

ZAPI COMBIACX Controller Port Definition

A1 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.

A2 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.

A3 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%.

A4 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.

A5 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.

A6 DI9 Input of the switch DI9. The input is activated when the

external switch is opened. The default function is the

controller “PUMP CUTBACK” input, opening the switch

pump speed is reduced.

A7 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.

A8 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.

A9 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 1

sec. period when a warning is displayed by the controller.

It also blinks with a 0.5 sec. period when an alarm is

displayed when no alarm are displayed, this output is OFF.

A10 GND This is the ground of the logic board.

A11 DI6 Input of the switch DI6. The input is activated when it is

connected to +Batt. The default function is the controller“LOWER” enable input.

A12 DI8 Input of the switch DI8. The input is activated when it is

connected to +Batt. The default function is the controller

“1ST” input: the pump motor turn at a defined speed.

A13 DI10 Input of the switch DI10. The input is activated when it is

connected to +Batt. The default function is the controller

“2ND” input: the pump motor turn at a defined speed.

A14 DI12 Input of the switch DI12. The input is activated when the

external switch is opened to ground. The default function

is the controller “CUTBACK2” input, opening the switch

truck speed is reduced. In the Sense Coil version this

input is connected to the AC motor sense coil.
