Issue What is the unit load (UL) of the SpaceLogic SP90 PIBCV Actuators that will help me to calculate how many SP90 PIBCV Actuators can be added on ComA and ComB of a SmartX Server. Product Line EcoStruxure Building Operation, Field Devices Environment SpaceLogic SP90 PIBCV Actuator SmartX Server Cause Require the Unit Load (UL) of the SpaceLogic SP90 PIBCV Actuator to calculate the number of actuators allowed on the RS-485 network.  Resolution The Generic application note AN01 can be applied with answers to the transceiver interface attributes below. The SpaceLogic SP90 PIBCV Actuator range uses the SN65HVD1780DR transceivers which are a failsafe transceiver (not requiring bias) and reduced 1/10 UL. In addition, there are no local bias resistors and therefore the 1/10 UL of the transceiver would be the total UL presented to the bus by the SpaceLogic SLP Room Unit. Transceiver Xcvr Unit Load Xcvr Failsafe Adaptor Circuit Bias Circuit Bias Load Total Unit Load Isolated 485 Bus SN65HVD1780DR 0.1 Yes None None 0.1 No Based on the above the total number of devices can be calculated as 32/0.1 = 320. The BACnet MSTP standard specifies that the address range for BACnet master devices is 0-127 and therefore a SmartX Server is limited to 127 devices per com port (254 total per Server) so this should effectively be the limiting factor. However, the documentation recommends using only up to 64 devices with the same RS-485 transceiver, or 32 devices with different RS-485 transceivers.   Since the SpaceLogic SP90 PIBCV Actuator does not have an isolated RS-485 interface it conforms to Generic RS-485 Network Device Configuration 1 in EBO Webhelp.  A network consisting of only SpaceLogic SP90 PIBCV Actuators should only require a 120-ohm termination resistor at each end of the bus and not require any bias resistors. Also, check out the SmartStruxure-RS485-Controller Unit Load Quick-Help video on the Exchange.

Issue SE7300 and SE8000 room controller fan speeds do not turn off when fan mode is set to auto. When cooling and / or heating is no longer needed, the fan speed remains at low speed. Product Line EcoStruxure Building Expert, Field Devices Environment SE7000 series room controller SE8000 series room controller Cause It is required that the fan be turned off when no demand for cooling or heating is needed. Resolution SE7300 controllers Enter the configuration mode of the room controller. Refer to page 19 of the SE7300 Series Installation Guide for the procedure to enter the configuration mode. In configuration mode, there is a parameter 'AutoFan'. The default mode for this parameter is 'AS'. In order for the fan to stop when there is no demand, the mode should be set to 'AS AD'. AS (Default) = Auto Speed during occupied periods. Fan is always on during occupied periods. Low, medium and high speeds operate on temperature offset from set point. AS AD = Auto Speed / Auto Demand during occupied periods. - Medium and high speeds operate on temperature offset from set point. Low speed operates on demand and will shut down when no demand is present. SE8000 controllers On the room controller, select the fan mode parameter from the home screen. The fan mode must be set to Smart in order for the fan output to function as expected. In Smart mode the fan will turn off when there is no demand for cooling or heating. For SmartStruxure applications of the SE8000 controller This issue can also be seen when binding to the "Value field of the Occupancy Command of the SE8000 controller. Make sure to bind to a priority, not to Value otherwise the fan command will not turn off.

Issue Satchwell ZKM series Rotary Actuator requires replacement due to obsolescence. Environment Satchwell ZKM Rotary Actuator installed on Satchwell MBF series Rotary Shoe Valve Body. Satchwell ZKM Rotary Actuator installed on Satchwell MZF series Plug and Seat Valve Body. Cause Obsolescence of Satchwell ZKM series Rotary Actuator Resolution OVERVIEW The Satchwell ZKM Actuator was compatible with both Satchwell MBF series Flanged Rotary Shoe Valve Bodies and Satchwell MZF series Flanged Plug and Seat Valve Bodies, subject to the installation of an appropriate Linkage Kit. Various models of the ZKM Actuator were available, each differing in the number and type of electrical interface provided, enabling the Actuator to be installed in a range of control applications. Interfaces included Transfer Switches, Auxiliary Switches and Feedback Potentiometers, thus resulting in differing wiring connection options between the ZKM Actuator and its associated Controller and other peripherals. Details of the numerous ZKM Actuator variations available may be viewed here. In view of the differing wiring connection options that may be found on site, it is intended to deal only with the most common 6-wire connection option here. Please therefore check the number of wires connected to the ZKM Actuator before proceeding, as this will assist in confirming the suitability of the ZKM Actuator 6-wire connection option replacement suggestion described here.   1.

The S-E Forta M800 Actuator may be used to replace an existing Satchwell ZKM series Actuator but it should be noted that where this is to be connected directly to a Satchwell Controller, an independent Transformer rated to provide the greater level of power required by a single S-E Forta M800 Actuator (50VA) compared to that available at the CZT Controller (10VA) will also be required. (e.g. S-E Transformer Type TR60) Details of the Schneider Electric TR60 Transformer may be viewed here In such installations not only will the ZKM need to be replaced but the associated Proportional Controller will also need to be replaced.   2. PROPORTIONAL CONTROLLER REPLACEMENT The ZKM Actuator was compatible with a number of Satchwell Proportional Controller types including Z Monotronic, CZT Series 1 and CZT Series 3 Z MONTRONIC CONTROLLER APPLICATIONS :- If the Proportional Controller is a Z Monotronic type then this should be replaced by the Satchwell CZT5305 Proportional Controller.
