Safety Features
The features listed in this section are designed with the safety of the operator in mind.
Fail-safe
The controller’s safety system includes a microprocessor watchdog which can detect software
failure, and a hardware fail-safe system. Every time the controller is powered-up, the software
checks that the fail-safe circuit is able to switch off the MOSFETs and open the contactors.
