The C3-CE is the first in a new line of AC motor controllers designed specifically to the requirements of EN ISO 13849.
Featuring EN ISO 13849 Category 3 hardware architecture, including dual microprocessors, dual inputs and a dedicated B+Safe output, this extension to PGDTs high performing, compact and cost-effective C3 family will provide vehicle OEMs with one of the worlds safest controllers for Class 3 trucks.
The C3-CE features twelve dedicated digital inputs that can be individually switched to 0V, open-circuit, B+ or a combination of these options to provide the active state. Flexible, yet simple programming facilitates up to six dual paths for safety functions such as prevention of travel and tiller control, both of which are listed in EN1175-1:1998+A1:2010 Safety of industrial trucks, Electrical requirements Part 1: General requirements for battery powered trucks. Single input, Category 2 architectures like those currently adopted by other controller suppliers, require the safety function to be checked at machine start-up and prior to the initiation of any hazardous situation. For typical pallet trucks this is inconvenient and potentially dangerous.
PGDTs Category 3 dual input design provides a safer and more convenient approach. The C3-CE also features a dual path analog input that accepts multiple types of throttle connections, including 2- or 3-wire resistive and voltage, for maximum safety and wiring simplicity.
