LED Purpose
If a POC (proof of closure switch) is present on the valve, this LED indicates that the valve seat is
open. This gives visual position indication per FM (Factory Mutual) 7400 and ANSI Z21.21 / CSA
6.5. LED gives status indication of the valve seat over which the LED is situated.
Open
If a POC (proof of closure switch) is NOT present, this LED indicates the solenoid is powered.
If a POC (proof of closure switch) is present on the valve, this LED indicates that the valve seat is
closed. This gives visual position indication per FM (Factory Mutual) 7400 and ANSI Z21.21 / CSA
6.5. LED gives status indication of the valve seat over which the LED is situated.
Closed
If a POC (proof of closure switch) is NOT present, this LED indicates the solenoid is not powered.
The Self Test LED indicates a valve test is being performed. Self Tests include circuit check
during initial power-up, external and internal VPS, leak detection test, manual low gas or high gas
pressure tests.
Self Test
NOTE: On BASIC (5) intelligence valves, this only indicates a circuit check.
Indicates a fault condition exists.
Refer to the VALVE FAULT CODES
Fault
Indicates a Low Gas Pressure fault condition exists when a SV2 Series Pressure Module is used on
the valve and programmed.
LGP
NOTE: The Fault LED will also be lit while this fault is active.
Indicates a High Gas Pressure fault condition exists when a SV2 Series Pressure Module is used on
the valve and programmed.
HGP
NOTE: The Fault LED will also be lit while this fault is active.
1. Valve electronics orientation is ordered as left-hand or right-hand mounted from the factory (defined as being viewed from the valve gas outlet / burner end).
If the electronics orientation is changed in the field (as illustrated in CHAPTER 10:
orientation procedure must be completed to ensure the LED annunciation continues to indicate status of the valve seat over which it is situated. This procedure
is part of the instructions in Chapter 10.
