Honeywell SV2 Series User Manual page 65

NOTES:
• The SV2 Series valves have internal algorithms that prevent the accidental or intentional removing of the Pressure
Module once the valve has been fully setup and is in use.
– If the installed/operational Pressure Module connector is disconnected and reconnected, a 19-Pressure Module
reading fault will occur and can be cleared via the valve reset button.
– When a Pressure Module is replaced on the valve, two lockouts will occur; 19-Pressure Module reading fault and 22-
Lo-/Hi-Gas pressure not configured.
₀ The faults cannot be fully cleared until the new Pressure Module is Accepted and the Hi-Gas/Lo-Gas Limits and/or
VPS are re-programmed.
₀ Note that the previously selected Lockout Type for the Hi-Gas/Lo-Gas Limits remain intact as well as the VPS setup,
but the Limit Setpoints are deleted and must be setup in order to make the Limits operational.
• To avoid the 2 lockout conditions mentioned above when replacing a Pressure Module:
– BEFORE installing the replacement Pressure Module, disable the Hi-Gas and Lo-Gas Lockout Types and the Valve
Proving Sequence (VPS)
– Perform the Verify Safety Parameters procedure to confirm the changes.
Replace the Pressure Module and plug in the electrical connector.
–
To make the valve operational:
Accept the new Pressure Module and serial number either via the Guided Valve Set Up or the Pressure Module tab in
–
the Setup & Tests / Settings menus.
If this step is not performed, 3 faults will occur upon entering the Hi-Gas/Lo-Gas Pressure or VPS setup screens. In
₀
order to allow setup functions, the Pressure Module must be Accepted and the valve reset button pushed.
Perform the Pressure Module setup procedures for Hi-Gas Pressure, Lo-Gas Pressure and/or VPS again to ensure
–
proper setup, since the original Limit Setpoints will be deleted.
Perform the Safety Parameters Verification procedure before the Pressure Module features and the valve will be
–
operational.
