For the compressor’s interlock circuit, when the pressure relief valve opens, is it only by starting the compressor that the interlock can be reset? The pressure relief valve can then be closed
Too little information has been provided. For this, you mainly need to check where the SIS interlock is connected. Generally, the emergency pressure relief valve being open prevents the booster compressor from starting. Also, it needs to be reset first before it can be shut down or turned on properly
I know; I’ll start compression first, then reset
If the SIS is not reset and the compressor will not start, reset it first before attempting to start the compressor
It should first be reset before compression can occur; it cannot be done if the conditions aren’t met.
Theoretically, it should be possible to close the pressure relief valve by releasing the interlock and then resetting it.
The activated interlock can be bypassed to manually close the pressure relief valve.
Depending on the temperature of the reactor bed, restart the compressor in place; if the reactor temperature does not rise excessively, the bypass interlock can be reset
