Over-Temperature Protection
The amplifier is also equipped with over-temperature protection.
Rev A and Rev B amplifiers:
If the average heat sink temperature rises above 100°C, then the amplifier will be disabled. The over-temperature
condition will trigger the #AMPERR routine if included in the program on the controller.
The amplifier will re-enable when the temperature drops below 100 °C.
Rev C and newer amplifiers:
If the average heat sink temperature rises above 80°C, then the amplifier will be disabled. The over-temperature
condition will trigger the #AMPERR routine if included in the program on the controller.
The amplifier will not be re-enabled until the temperature drops below 80°C and then either an SH command is
sent to the controller, or the controller is reset (RS command or power cycle).
Rev C Amplifiers began shipping in December 2008.
