Issue What is the life expectancy of the LCD display of smart sensors with available display? Environment Smart sensor with LCD display Cause Display life expectancy. Resolution The Life expectancy of an LCD Display is 50K hours. Note: Life is reduced if LCD works under direct sunlight. If you use a LED backlight in a LCD module the life expectancy of the LED is 30K to 50K hours, depending on the forward current. EL backlights are available but we don’t recommend them because of their short life (3K hours) and EMC problems. The AC voltage is generated by the DC to AC inverter.  

Issue Even though Windows Server 2008 R2 is exclusively a 64-bit operating system, 32-bit applications are supported by enabling the WoW64 optional feature. NOTE: These are general instructions for utilizing the WoW64 function. Not all Schneider Software will be able to run in an emulated environment. If uncertain, please check with Product Support Services to ensure proper installation. Product Line Andover Continuum, Field Devices, Other, Satchwell MicroNet, Satchwell Sigma, TAC INET, TAC Vista Environment Windows Server 2008 R2 WoW64 feature. All 64bit OS Cause If the WoW64 feature is not enabled and you try to run a 32-bit application, the application will fail to execute. WoW64 option in in undesired state. Resolution If the WoW64 feature is not enabled and you try to run a 32-bit application, the application will fail to execute. The WoW64 execution layer is an optional component that is installed by default on R2 releases. You can save resources by removing the feature if you are not going to be running 32-bit applications on your Server Core install. Install the WoW64 Execution Layer using the following command: dism /online /enable-feature /featurename:ServerCore-WOW64 If your solution has a .NET 32-bit dependency, then also invoke the following sequence: dism /online /enable-feature /featurename:NetFx2-ServerCore dism /online /enable-feature /featurename:NetFx2-ServerCore-WOW64 Note: In Windows Server 2008 R2 RC1, WoW64 is enabled by default. If you don't want WoW64 enabled, just disable the feature as follows:  dism /online /disable-feature /featurename:ServerCore-WOW64

Issue The Forta range actuator does not fit onto the V321 Valve. Environment V321 M800 M1500 MV15B M3000 Cause The actuator has a 10mm fitting, the valve (DN65 to DN100 only) spindle has a 8mm stem. Resolution On V321 valves size DN65 to DN100 an adaptor piece is supplied with the valve part no. 880-0133-000 to adapt the valve spindle to the actuator drive. The part no. 880-0133-000 can be ordered separately.

Issue Which actuator should be used as replacement to a M15 actuator that is mounted on a VTRA Valve? Environment VTRA DN65 M15 24V / 12VA 15 Nm 300s / 180° Cause Currently used actuator is no longer available. Resolution Use EM9/180 (part no 8601110000) together with Linkage kit E/M9-VTRA (part no 8600990000).

Issue Is the DC1100C still available? Is the DCCOMMS software still available? Environment DC1100C DC1100 C DCCOMMS DC COMMS DC1100 DC1400 DC1000C DC1000 C Cause Is the DC1100C and the DCCOMMS software still available? Resolution The DC1100C had the communication module so that the controller could be interrogated remotely. This controller is no longer available. The DCCOMMS software ran in a DOS environment and is also obsolete. The DC1000C or DC1100C must not be confused with the DC1100 or the DC1400, these are the same controllers but without the communication interface and are still available.

Issue What is necessary to do in order to change settings in the Kamstrup Multical 601 meter? Environment Kamstrup Multical 601 Cause How to change the basic settings in pulse calculations from MWhrs to kWhrs, and also other settings.   Resolution Metertool software (part no: MAHWSWTOOL) together with the Optical eye USB hardware (part no: MAOPTICUSB) is required for this type of configuration. For more information, please take a look at MeterTool for Multical 601 presentation.

Issue According to the datasheet, there should be a DIP switch for output voltage adjustment for Veris CO sensor. But some of them haven't such DIP switch. Environment Veris Sensor Cause There are several models for Veris CO sensor. For example, GWVAS is the wall mount sensor with voltage output signal, while GDMAS is the duct mount sensor with current output signal. The sensor with current output signal hasn't such DIP switch for voltage output. Resolution This model of product hasn't such DIP switch.

Issue Is it possible to run a Forta series actuator on 24VDC? Environment TAC Forta series actuators: M300 M310 M400 M750 M800 M1500 M3000 Cause The TAC Forta series actuators older documentation suggests it can only be run on 24VAC only. Resolution The TAC Forta series actuators can run on 24VAC +/- 25% or 24Vdc +/- 10%. For more specific details on tolerances, please see the data sheet for each product.

Issue Controlling a Forta actuator from PLC system using 0-10V output. Environment TAC Forta actuator  PLC controller Cause The PLC system is using a 0-10V control output to control the TAC Forta (MX and X1 input), powering the TAC Forta (G and G0 input)using a separate transformer. Resolution As long as the PLC system and TAC forta units are fed from separate transformers, this should cause no problem, and galvanic isolators on the control signal should not be required. Make sure to not mix up G and G0 in case several TAC Forta actuators are fed through the same transformer.

Issue Schneider Electric part number equivalent to Belimo LMQU24-SR  Environment Belimo LMQU24-SR Cause Internal purchasing instead of external. Resolution No cross reference is available. The Belimo actuator in question is not represented in our portfolio and needs to be purchased from the manufacturer directly.

Issue There are different versions of TAC Forta actuators available on the global market. Environment Forta actuators on the global market. M400 M400A M800 M800A M1500 M1500A Cause There are different types of Fortas available. Resolution The "A" version of the Forta actuators are designed to be used on the US market. There are several differences between the "A" series and the regular type, but the key ones are: UL approval Electrical connections designed to conform to US standards The VB version is equipped with a short yoke to fit directly on the VB series of valves used on the US market.

Issue When defining configuration on SE7300 part no, your choice is between "0" (override) and "5" (possibility to change between °C and °F in interface). Environment SE7300 Cause its not possible to have both override and °C/°F feature Resolution When defining the part number, you will have to choose. The override feature is usually the preferred choice in industrial applications, while the °C/°F feature is used for Hotels and similar, where users are given the possibility to change unit of desired temperature.

Issue When specifying the configuration of the SE7300 you can choose between "50" and "55" in step 5 of the part number. Product Line EcoStruxure Building Expert, Field Devices Environment SE7300 Cause Different options of configuration when defining the part no for the SE7300 Resolution The difference is that the "50" option is PIR Ready, but PIR cover of unit is not included. Option "55" is with the PIR cover already mounted upon delivery. 

Issue Looking for actuator with position feedback signal for V321 (V292, V222) DN125-DN150 since M22/M50 does not provide this option. Environment V222 DN125 V222DN150 V292 DN125 V292 DN150 V321 DN125 V321 DN150 M22 M50 Cause Actuator with positioning feedback signal for DN125 - DN150 valves Resolution There are currently no suitable actuators available that gives the Forta features on the M22/M50 actuators. Also, there is no linkage kit that would make the Forta series actuators fit on the DN125 and DN150 size valves, due to its different design.
