11 ONE SHOT INSTALLATION PROCEDURE

This section of the manual describes the basic connection procedure.

The truck needs (to move) a minimum I/O dotation that it is mandatory: this

minimum dotation is listed in the Steps from 1 to 8 below.

Step1 Connect a potentiometer in the range 0.5K to 10Kohms, to modify

the wished speed, between CNB#12, CNB#10, CNB#11.

Step2 Connect two travel demand switches. The FWD travel demand must

be connected between a battery (key) voltage and CNB#6. The

REV travel demand must be connected between a battery (key)

voltage and CNB#5. Only one of them can be active at the same

time. They become active when connected to a key voltage (the key

voltage is supplied on the CNB#2 connection).

Step3 Connect a tiller (or seat) switch enabling/disabling the truck motion

between CNB#3 and a key voltage. It becomes active, enabling the

motion, when closed to a key voltage (the key voltage is supplied on

the CNB#2 connection).

Step4 Connect the encoder in the motor shaft between CNA#9=VDD,

CNA#10=GND, CNA#19=CHA, CNA#20=CHB. The VDD voltage

may be 13V or 5V depending on a jumper inside the controller (see

also 8.4).

Step5 Connect the plus battery voltage through a key switch at the KEY

input CNB#1 (this is the input for the logic supply).

Step6 Connect the Main Contactor Coil to CNA#1 and CNA#2. The

contactor must make and take the plus battery power cable to the

+BATT power terminal of the AC1.

Step7 Connect the motor and the minus battery to the corresponding

power terminals of the AC1.

Step8 Connect the Electromechanical Brake between CNA#3 and the tiller

switch (when the tiller switch opens, the electromechanical brake

gets de-energized braking the truck). A 3Ampere freeweeling diode

(arc soppressor) with the anode to CNB#3 must be connected in

parallel with the Electromechanical Brake Coil.

The Steps from 1 to 8 describe the installation operations that is mandatory to do

in order your truck moves. Obviously the AC1 may execute a wider set of optional

services as:

1) to handle some speed reductions requests

2) to handle a analog sensor inside the motor

3) to handle a proportional braking

4) to handle an On/Off forks lowering valve

5) to handle a pump contactor

6) to handle a belly switch and an Inching operative mode

7) to handle the communication via CAN Bus with our MDI-PRC

8) to handle a proportional input for the forks lifting/lowering

You must fill your I/O dotation with your optional functions. The optional functions

are shown in the connecting drawing and descripted in detail inside this manual.

The index may help you.
