The C3-CE from PG Drives Technology is the first in a new
range 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 PGDT’s high performing,
compact and cost-effective C3 family will provide vehicle
OEMs with one of the world’s safest controllers for Class 3
trucks.
Two versions are available – 200Arms and 250Arms –
providing the most economic and efficient solution for the
application. The C3-CE is compatible with all types of AC
induction motor.
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 ‘EN11751:1998+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.
PGDT’s 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.
Four 2A outputs and one 3A output allow control of line and
lift contactors, a lower valve, plus an electro-magnetic brake.
All outputs are protected against wiring errors and contain coil
suppression circuits, meaning external diodes are not
required. The C3-CE also incorporates an innovative B+Safe
high-side coil supply that electrically isolates all of the lowside switches in the event of a hardware or safety function
failure.
The innovative construction methods employed by the C3-CE
ensure reliable and repeatable assembly of the electronic
enclosure, which results in consistent protection of the
electronic circuits from the environment and efficient transfer
of heat to the baseplate. The design is compliant with all
relevant international materials handling vehicle standards,
e.g. EN 1175-1 (EN ISO 13849), UL 583 etc.
