The device features extensive on-chip fault detection including detecting DIO driver short circuits longer than 650 osec, DO driver short circuits longer than 440 osec, reverse polarity protection, undervoltage detection, and thermal protection including overtemperature warning and thermal shutdown.
Automatic error reporting for detecting open and short circuits, brown-outs, and overtemperature conditions make this subsystem ideal for demanding, precision industrial control and automation applications.
Standard safety items: Control of thermocouple disconnection, Control of thermocouple against overtemperature, Failure of surface temperature of furnace, Air cooling fan stop)
Temporarily isolating a loop for 15 seconds should not result in overtemperature conditions at the electronics rack.
The controller can measure a number of system parameters, including bus status, battery status, rectifier and load current, overvoltage, rectifier failure, AC power fail, and battery overtemperature.
It incorporates DC bus undervoltage and overvoltage monitoring, and is comprehensively protected against conditions such as overcurrent, overtemperature and motor short-circuits.
According to NATOPS, an engine overtemperature results in the flashing of the warning chevrons and the activation of the stall-warning legend and aural tone, neither of which occurred during the initial stages of our engine failure.
Overtemperature and undertemperature safety thermostats protect the chamber from temperature variance.
