Thermal Shutdown In Critical Conditions - HBM Genesis GEN5i User Manual

GEN5i
Every one of the automatic range changes will be identified within your
measurement data. Not only will your measured input be scaled correctly with
the adapted input range, but also the exact moment the automatic range
change happens is identified within Perception software.
As the highest selectable range is ±1 kV the ultimate protection for the system
will be to disconnect the input from the external signal source. This step will
only be executed if the system is in the ±1 kV range and local temperature is
not within maximum operating limits. Disconnecting from the external signal
source is done by grounding the input. When inputs are grounded, the only
connections to the external signal are the input connectors and the input pin of
the ground relay.

Thermal shutdown in critical conditions

This protective scheme allows for any overload condition the input would be
confronted with during normal operation. For any other failure condition that
would result in excessive heat dissipation, the system has a last protective
stage built in. When local temperatures reach a critical condition the system will
turn-off the mains power automatically to prevent damage to the system or other
systems near the GEN series system. Maximum and critical temperature
conditions are defined as such that it is very unlikely the system will ever reach
this critical condition when operating within its specified conditions.
