Electronic control Logitrans Controller Electric system
The Logitrans controller is an electronic control unit which uses microprocessor technology and has been
developed specially for Logitrans.
The forward/reverse function is fully electronically controlled by a Power FET system.
The variable speed is controlled by the handle employing two Hall effect units and a magnet.
In this system there are no moving parts. The electronic unit is completely enclosed and therefore unaf-
fected by dust and water.
It is possible to set a range of parameters so that the truck will have the exact characteristics the customer
requires. A number of special functions are also available in the controller:

Battery meter - continuously indicates the residual capacity of the battery.

Hour meter.

Counter for the number of battery charging cycles carried out.

Counter for the number of battery discharges to under 15% of battery capacity that have
occurred.
The serial no. of the controller is printed on the side of the box. It can also be read by a PC .
The following connectors are available on the controller:
+ and ÷ Power supply from the battery (through the main relay).
1 - 4. Connections to the drive motor, see diagram for cable connections.
5. 15-pin socket for diverse connections:
Power supply, raise, lower, main relay, handle position, etc.
6. 12-pin socket for the handle cable.
7. 9-pin socket, partly used by the display/battery indicator (optional extra), partly for
communication with a PC or hand terminal .
8. 4-pin socket is connected to the raise/lower functions - can be used for remote control.
9. Mini display for displaying operational messages, see “Operational messages on the Logitrans
controller mini display”.
10. Diode - illuminates to indicate a defective controller which must be sent to the factory for repair.
