  • Page 57 Introduction The Pressure Module may be used on most SV2 Series valves for multi-function operation. It contains embedded pressure sensors to cover the designated range of the Pressure Module model and can be used for functions including low gas pressure, high gas pressure, VPS (valve proving sequence), leak detection sequence operation and/or pressure monitoring via Modbus.
  • Page 58 SV2 Series Safety Shut-off Valves Mounting The Pressure Module can be mounted in any of the four (4) positions on the valve body and is keyed for specific mounting orientation. The seals of the Pressure Module are designed to cover the center and upper pressure access ports of each mounting location.
  • Page 59 Software algorithms are embedded in the SV2 Series valves to identify not only low and high gas pressure limit faults and VPS test failures, but also when a Pressure Module is un-configured, if there is a reading fault with the Pressure Module, if a pressure limit setting is unusable based on the pressure range of the selected Pressure Module and if the selected Pressure Module is incompatible with the applied valve pressure.
  • Page 60 Since the SV2 Series valves cannot sense a low gas pressure condition prior to opening, it will actively sense and react to the condition once both valve seats are opened. The response time upon sensing the condition is 2.7 seconds after which the valve seats will be closed and the valve will annunciate the fault condition both on the valve face via the LGP LED and the HMI / PC Tool, if connected.
  • Page 61 SV2 SERIES SAFETY SHUT-OFF VALVES USER MANUAL In order to properly program the high and low gas limit settings, the burner must be run so that the embedded pressure sensors can measure the actual pressure that should occur during low fire and high fire conditions, respectively. While the burner is running after stabilization has occurred, the user must select a % over or under the measured operating pressure for the high and low gas limit settings.
  • Page 62 When a VPS sequence is initiated by the external control, the SV2 Series valve intelligent models will automatically determine a VPS sequence is being performed since one valve seat at a time is selectively powered. Accordingly, the valve will initiate its internal leak detection routine, using the attached Pressure Module to measure the pressure rise or decay in the volume between the two safety shut-off valve seats.
  • Page 63 • When utilizing the VPS functionality with the Pressure Module, a NOVV (normally open vent valve) cannot be present unless it is powered during the entire VPS test time. The SV2 Series valves do not provide for cycling the NOVV.
  • Page 64 – PRESSMODx4: 16mbar / 6.4 in wc / 0.23 psi • In case the SV2 Series valve cannot take reliable pressure readings during the external VPS sequence, the SV2 Series valve will lockout. • Very low leakage levels of less than 2 liters/hour (= 33.3 ml/min = 0.07 CFH), which are well below any allowed level, may result due to transient pressure changes caused by the valve balance diaphragm.
  • Page 65 SV2 SERIES SAFETY SHUT-OFF VALVES USER MANUAL 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.
  • Page 66 SV2 Series Safety Shut-off Valves Introduction and Flange Selection Flanges are required to mount each valve and provide connection to standard NPT or BSP gas pipes. There are several available flanges per valve body size. Flange kits designated as AB are for the 1 inch (DN25) valves while flange kits designated as CD are for the 1 ½...
  • Page 67 Any intelligent features utilized are programmed via the Modbus connection to the SV2 Series HMI or PC Tools. Intelligent features include valve Modbus address + communication speed, low gas pressure, high gas pressure, VPS (valve proving sequence), fuel/air ratio, leak detection sequence and metering.
  • Page 68 • More than one power supply disconnect can be involved. CYBER SECURITY NOTICE SV2 Series products contain electronics and software. Care should be taken by the installer / facility management to guard against unauthorized access to the valve and to the programming interface for parameter modification (if applicable).
  • Page 69 Introduction and Replacement Solenoid Selection The SV2 Series individual solenoids can be replaced in the field without replacing the entire valve, should the need arise. Replacement solenoid part numbers are identified by ‘COIL’, followed by the valve body size identifier and applicable voltage.
  • Page 70 Table 15 and/or the model information on the solenoid assembly installed on the valve. • For valve the mechanical and electrical installation, follow the SV2 Series Valve Replacement Electronics installation instruction document, 32-00039, which is packed with the replacement assembly.

  • Page 72 Delta P across FARMOD gas inlet to the Pref outlet Approvals The Fuel/Air Module is not a stand-alone product and must be used with a SV2 Series valve and thus is specified as part of the valve approvals. Amplification Factor Accuracy The achievable accuracy or repeatability of the amplification factor depends on the adjusted value.
  • Page 73 2. ±1.5% of actual sensor reading Fuel/Air Module Introduction The Fuel/Air Module is installed on SV2 Series premix valves for fuel/air regulation (valve model numbers starting with V2V). Each FARMOD contains multiple sensors for accurate measurement of the differential air and gas pressures. Dedicated control electronics and software accurately regulate the fuel/air ratio based on the Fuel/Air Module signals.
  • Page 74 FARMOD is unknown. • The SV2 Series valves have internal algorithms that prevent the accidental or intentional removing of the Fuel Air Ratio Module once the valve has been fully setup and is in use. If the FARMOD cable is disconnected, the valve will lockout.
  • Page 75 Table IMPORTANT: • The fittings selected by Honeywell from specific brands and types assure free sample flow to and from the SV2 Series fuel/ air ratio premix valve. • If any other fittings are used, the sample flow to and from the valve can easily get obstructed and affect the combustion quality.

By selecting a short Ramp Period (and an extra startup delay of 0 = Ignition Period) the control is started almost directly after opening of the two safety valves.
  • Page 96 Ignition Period and Ignition Setpoint Parameters The SV2 Series valve allows the user to make the fuel/air mixture rich or lean during the Ignition Period relative to the amplification setting for the appliance RUN mode or the start load. This occurs AFTER the Ramp Period and Hold On Period timers have expired, when the valve control loop starts to modulate.
  • Page 97 Record Ign. Air Level parameter The SV2 Series valve will check the combustion air level during the ignition phase. To do so, the ignition air level needs to be recorded under normal conditions by checking this box.
