Warning Hazard of Electric Shock: Remove all power from all devices before removing any covers or doors of the system. Disconnect power at the device and at the power source. Issue The SLO Label shows an incorrect value range for kL. Product Line Field Devices Environment SpaceLogic SLO series Lux sensor Cause The label on the SLO shows the incorrect value range for kL. Resolution SLO: The product specification sheet states the Ranges for the jumper as: - 0 to 500 lx and 0 to 20 kLx The range to 500 lx can be seen on the circuit board. The product’s label shows 0 – 4kL The manufacturer has confirmed the label is incorrect the value should be 500 lx, New labels will be used in production from August 2022.   SLR: The tense delivery situation during the pandemic, especially for electronic components, has forced the manufacturer to make technical changes to the SLR in order to stay able to continue to deliver reliably. The range has extended from 0.4 to 0.5 kLux. These changes are incorporated in the corresponding instructions, provided with the devices. New labels will show the extended range.

Issue What is difference between valve rangeability and turndown ratio? Product Line Field Devices Environment Valves Cause Definition of the terms helps explain the flow outcomes. Resolution Rangeability - maximum controllable flow divided by minimum controllable flow Turndown ratio - normal maximum system flow divided by minimum controllable flow.   Rangeability is the inherent characteristic of the valve and turndown ratio is the installed characteristic.

Issue VTRA Valve Body requires replacement due to obsolescence. Product Line Field Devices Environment VTRA 3-port Mixing Valve Body Cause Obsolescence of VTRA Valve Body Resolution VTRA Valve Bodies are obsolete and have been for many years. VTRA Valve Bodies were available with either Flanged or Screwed connections.  Details of the various size / connection combinations available appear VTRA Specification Sheet. REPLACEMENT OF VTRA FLANGED CONNECTION VALVE BODY A replacement for the VTRA Flanged Valve Body (32-80mm) may be selected from the VTRE range of Flanged Valve Bodies, see VTRE S-E Specification Sheet for more datails. N.B. It should be noted that the VTRE Valve Body is rated PN6 whereas the VTRA was rated PN10. The VTRE Flanged Valve Body may be operated by the EM9 Actuator, see Alternatively the VTRE Flanged Valve Body may be operated by the M9B Actuator, See EM 9 Specification Sheet for more details. No Linkage Kit is required to mount the EM9 or M9B Actuator on the VTRE Valve Body. Alternatively a replacement for the VTRA Flanged Valve Body (65-80mm only) may be selected from the the S-E VG311F and V321 3-Port Flanged Valve Bodies, more details can be found in the Venta VG311F 65-150C Specification Sheet and the Venta V321 Specification Sheet N.B. It should be noted that the S-EVG311F and V321 Valve Body are rated PN16 whereas the VTRA was rated PN10.   REPLACEMENT OF VTRA SCREWED CONNECTION VALVE BODY A replacement for the VTRA Screwed Valve Body (15-50mm) may be selected from the MB range of Screwed Valve Bodies, see the MB/MBF data sheet for more details. The MB Screwed Valve Body may be operated by the MD10B series Actuator, see the MD10B specification sheet for more details. Alternatively the MB Screwed Valve Body may be operated by the MD10A Actuator, see the MD10A specification sheet for more details.

The Schneider Electric Forta M800 Actuator may be used to replace an existing Satchwell ALE series Actuator but it should be noted that where an existing Satchwell ALE series Actuator has been connected directly to a Satchwell Controller, an independent Transformer rated to provide the greater level of power required by a single Schneider Electric Forta M800 Actuator (50VA) will also be required. (e.g. Schneider Electric Transformer Type TR60)   Where an existing Satchwell ALE series Actuator has been connected via an independent Transformer, it is possible that the Transformer may have been rated to provide the level of power required by a single ALE series Actuator (9.5VA) only.   In such circumstances the existing independent Transformer may also require replacement by another independent Transformer, rated to provide the greater level of power required by a single Schneider Electric Forta M800 Actuator (50VA) (e.g. Schneider Electric Transformer Type TR60) Details of the Schneider Electric M800 Actuator may be viewed here Details of the Schneider Electric TR60 Transformer may be viewed here

Issue What is valve authority? Product Line Field Devices Environment Any valve Cause Information on Valve Authority to obtain good control. Resolution Valve Authority = (Pressure drop across fully open control valve) / (pressure drop across the remainder of the circuit) + (pressure drop across fully open valve) In other words, valve authority within a system indicates how much of the system's total pressure drop comes from the control valve. It is common practice to consider the range between .2 to .5 as "acceptable" authority for proportional valve.
