Unsurpassed durability
The AWC 500 is designed for high durability and verified
by HALT (Highly Accelerated Life Test) testing. Built to last
for more than 20 years, the controller has been constructed
using a selection of highly durable components with a long
supply life time. We provide a 5 year warranty on the AWC
500 controller - the longest in the wind industry.
Hot and cold climate
Handling cold starts from a guaranteed -40ºC, the AWC 500
secures a safe and controlled turbine start-up in very low
temperature environments.
The highest operating temperature for the AWC 500 is 70 ºC.
This is an advantage to the controller life-time. For every 10
degree the temperature is higher, the life-time is extended - a
general rule of thumb.
Surge power on the AWC 500 is DM 2 kV, CM 4 kV. Twice
the industrial standards on both power supply and I/O
terminals. These high standards improve robustness of the
controller enabling it to toleratefor instance lightning strikes
on the turbine.
All PCB modules are coated with an eco-friendly protective
layer.
High altitude installations
The controller is designed for full operation on all I/Os and
communication interfaces without requiring additional cooling
in high altitude installations up to 4,000 m.
Tolerance to voltage dips
If the power supply suddenly drops, the complete AWC 500
system including all I/O modules within the AWC 500 rack(s)
will continue to operate for a minimum of 50 milliseconds up
to 1 second.
If power supply returns within this period, the AWC 500
system will continue uninterrupted operation. If power is still
absent after the power-loss protection period, the AWC 500
will enter its safe shutdown cycle in which it will prioritize
as clean shutdown amongst writing data to FRAM and
dedicated areas of the file system cache to the internal flash.
This ensures that all data from the application is sent to the
power-loss protected data storage and will be available to
the application, when power supply returns.
Watchdogs on 4 different hardware and software
levels
To monitor the operation of the AWC 500 system, watchdogs
on different levels are featured, from each individual module
EtherCAT slaves, EtherCAT master, Operating system
services running to application watchdog.
