Issue What is the difference between the M1500 and the M1500A actuators? Environment Forta M1500 M1500A Cause Why has the "A" been dropped from the specification number? Resolution Originally there were two specifications; M1500A which fitted to the control valve using a "U-Bolt". M1500A-VB which fitted to the valve using a "Screw Mount". The M1500 actuator is fitted to the valve using an "U-Bolt", if a "Screw Mount" is required, then the appropriate linkage kit should be used.

Issue Can you have two multiplexed Wiegand readers and two multiplexed RS-485 readers on the same Controller or Reader Module? Product Line Security Expert Environment Security Expert SP-C SP-RDM2 Cause Unsure if two reader protocols could be used on the same reader module. Resolution For this you will need to use another reader module. One module (this could be the SP-C) for multiplexed Wiegand readers, and another for multiplexed RS-485 readers. When using multiplexed Wiegand readers you will need to connect the D1 cable from the exit reader to the opposite reader port. So in multiplex reader mode you can have 4 Wiegand readers, or 4 RS-485, but not two of each. If Wiegand is being used both reader ports are setup as Wiegand. See details on this in the SP-C System Controller Installation Manual starting on page 28. The wiring for multiplexed RS-485 readers doesn't require any connections to the opposite reader port.

Issue What sensors can be used in Clean Rooms  What sensors can be used outdoors for temperature measurement What sensor can be used in a swimming pool What sensor would be explosive proof What color is the wall sensor and are custom colors available Environment Building Automation System such as I/NET, Vista, or Continuum at a site containing a clean room, swimming pool, or outdoors Cause Questions concerning the uses of Schneider Electric sensors in Clean Room applications Questions concerning temperature sensors for Outdoor installations Questions concerning temperature sensors for swimming pools Questions concerning explosion proof sensors* Questions concerning color and custom colors for sensors Resolution All the Schneider Electric temperature sensors found in the HVAC Sensor Catalogue as well as on iPortal provide high accuracy and can be mounted on the wall, in ducts, or in a J-Box. Appendix A provides the accuracy for each of the temperature sensors. Color: STR series wall sensors are: Front Cover: White NCS S-0500 N Core Plate: White NCS S-0500 N and Gray NCS S-2500 N Base Plate: Gray NCS S 1502-R Manufacturing in custom colors in not available. One option could possibly to have the sensors locally custom finished to meet customer's requirements. While there is not a direct cross reference to RAL colors, our engineering team has found the closest alternates. Please see the attached pdf. Clean Room: Depending on the specified limits of the clean room, the variety of sensors offered by Schneider Electric are possible solutions. Thing you may want to research are the standards required for the site. Clean rooms are a controlled environment where products are manufactured. It is a room in which the concentration of airborne particles is controlled to specified limits. Eliminating sub-micron airborne contamination is really a process of control. These contaminants are generated by people, process, facilities and equipment and must be continually removed from the air. The level to which these particles need to be removed depends upon the standards required. The most frequently used standard is the ISO 14644 Standards, which were first formed from the US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones.  ISO 14644 is a document that establishes standard classes of air cleanliness for airborne particulate levels in cleanrooms and clean zones. Strict rules and procedures are followed to prevent contamination of the manufactured product. The only way to control contamination is to control the total environment. Air flow rates and direction, pressurization, temperature, humidity and specialized filtration all need to be tightly controlled. Outdoor:  Schneider Electrics selection of Outdoor Temperature Sensors are the STO100, 200, 500, & 600. These outdoor sensors are intended for outdoor wall mounting. Variants are available for Vista, I/NET, Continuum and Satchwell systems. The body has a 20mm conduit entry and the product is supplied with a conduit gland. Range -40 to +90 °C Accuracy See Appendix A: Table A, C, F in the attached HVAC Sensor Catalog.pdf Outdoor Temperature Sensor STO100 Order Code 5141100010 Part Number STO100 System Vista, Xenta Outdoor Temperature Sensor STO200 Order Code 5123246000 Part Number STO200 System I/NET Outdoor Temperature Sensor STO500 Order Code 5141104010 Part Number STO500 System Continuum Outdoor Temperature Sensor STO600 Order Code 5126060000 Part Number STO600 System Satchwell Outdoor Temperature Sensor STO600D Order Code 5126000000 Part Number STO600D System Drayton Outdoor Temperature Transmitters STO300 The STO300 transmitter is supplied as a complete unit, comprising a sensing element and an amplifier mounted in a housing which is resistant to ultraviolet light. The transmitter is intended for mounting on an outside wall, on the north side where possible. The transmitter is connected over a 2-wire cable, which serves both as power supply and signal transmission. The reading of the measured signal is made over an external load resistance. Outdoor Temperature Sensor STO300 -50/50 Order Code 006920501 Part Number STO300 -50/50 System All Note for each of these outdoor sensors, find the Description, the Order Code, Part Number, and the System it works with for the iBAS (intelligent Building Automation System) Please note the difference in Weatherproof and Outdoor. I put a lot of these outdoor sensors in at a university in Texas, and always installed in places that were a little protected. I found that under porches, up under the eves and out of the sun, or along a loading dock out of the rain and ice gave me accurate readings. Swimming Pool: In the piping system of a swimming pool is a corrosive environment with steadily harmful and gradually destructive minerals and chlorine in the water which present a challenge finding sensors able to withstand for extended periods of time. Schneider Electric makes several immersion temperature sensors. Beginning on page 12 of the above HVAC Catalogue, there is a variety of immersion sensors for the different iBMS lines.  One example is the STP660 is a Temperature Sensor for the European market, and intended for immersion mounting in pipe or the circulating systems. The stainless steel probe is a good solution but remember,  if the sensor is to be installed in pool water that contains chlorine, the best bet is to use a stainless steel pocket. I suppose it all depends on if sensor is in pipe associated with the secondary pool side of the system or the heating side of the system. If the sensor head is in an area exposed to Chlorine, then there may be an issue.  Chlorine may attack the solder connections of the wired joints inside the sensor. In the old days products from Satchwell used to produce special sensors for such applications where the wire connections were varnished in order to prevent corrosion. I think at the end of the day, our sensor would have a similar life expectancy to other devices in the plant that were no designed for use in such corrosive atmospheres. Explosion proof sensors: Schneider Electric does not manufacture explosion proof sensors. We do not partner with another manufacturer who provides such sensors. The closest is an 3rd party explosion proof enclosure with one of our available sensors. Our sensors are designed for building installations and if in extreme environments, we suggest enclosures.
