Fireye BurnerPRO - BurnerPRO Valve Proving Sequence Steps; Valve Proving Test Execution

37
®
Proving steps:
1. Both safety shutoff valves are in the closed position at the start of valve proving sequence.
2. The downstream valve (MV2) is energized (open) for 3 seconds. Thus, evacuating the test space.
3. The downstream valve is closed after the evacuation time.
4. The system monitors the pressure switch within the configured TEST TIME 1 window to verify that the
upstream valve is not leaking. If the pressure switch is energized (makes) during this window, the system
will stop the valve proving test and proceed to lockout. Otherwise, the system will proceed to the next
phase of the test.
5. The upstream valve (MV1) is open for 3 seconds. Thus, pressurizing the test space.
6. The upstream valve is closed after the pressurization time.
7. The system monitors the pressure switch within the configured TEST TIME 2 window to verify that the
downstream valve is not leaking. If the pressure switch is de-energized (drops out) during this window, the
system will stop the valve proving test and proceed to lockout.
8. Upon successful completion of TEST TIME 2, the valve proving test is deemed complete and the Burner-
PRO proceeds to start the pre-purge cycle.
