This fault state is not latched. It is up to the user to latch this error if desired.
Recommended practices
This Guardian Series transducer must be installed in such a way that the opening of the
output relay will bring the system to a safe state. In this safe state the instrument that is
monitoring the pressure should be left operational.
This error indication is not latched. If it is necessary to latch the error until it is manually
reset, this is the user’s responsibility.
At startup and on a periodic basis the safety system should be tested to ensure proper
operation. This will require applying a pressure to the Guardian Series transducer that is
over the safe level but less than the maximum pressure. Verify that the protective measure
is initiated to take the machine to a safe operating condition.
