Issue What entries are needed in the INPUT_XLATE table for the Sigma digital input to work? Environment Sigma gateway.txt IC GEN DDE IC GEN OPC Cause The Sigma digital inputs operate a reverse logic of 100.0 = off and 0.0 = on.  This needs to be reflected in the IC GEN Gateway.txt file XLATE table Resolution 1.  For the IC GEN gateway.txt input XLATE table when mapping to digital input objects; [INPUT_XLATE] count=2 Item0=1 / 0.0      ;DDE input of 1 = DI on Item1=0/ 100.0  ;DDE input of 0 = DI off 2. For the IC GEN gateway.txt output XLATE table when mapping from digital output objects; [OUTPUT_XLATE] count=2 Item0=0.0/ 0        ;D0 off = DDE output of 0 Item1=100.0/ 1   ;D0 on = DDE output of 1

Issue SVT Optimiser Controller does not enable the controlled space to recover to the required day temperature after an unoccupied period during which the inside air temperature has fallen to 12°C. Environment SVT4201 Optimiser Controller fitted with Analogue Time Switch. SVT4251 Optimiser Controller fitted with Digital Time Switch. Cause SVT Optimiser Controller Time Switch settings do not allow for selected Design Preheat Hours (DPH) Resolution SVT Optimiser Controller Time Switch settings should allow for selected Design Preheat Hours (DPH) SVT Optimiser Controller Time Switch settings should be carried out as follows :- Set Td to "Day" temperature required during occupancy. Set Tn to minimum "Night" temperature required during unoccupied periods. Set DPH to design preheat time. DPH is the maximum time required in order to enable the controlled space to recover to the required day temperature after an unoccupied period during which the inside air temperature has fallen to 12 deg. C. Select the approximate time in whole hours on the rotary switch (1 to 5 hours) Fine trim +/- 1/2 hour on the associated setting potentiometer. Note.  ALL "ON" times must be set earlier than the start of occupancy by the selected pre-heat time (DPH) set at (3) above. Example : DPH = 2 hours Occupancy time = 8.00 a.m. Set Time Switch "ON" time to 6.00 a.m. Setting the Time Switch "ON" time to 6.00 a.m. will enable the SVT Optimiser Controller to switch the plant ON at any time between 6.00 a.m. and 8.00 a.m. depending on the heating loss experienced in the controlled space during the preceding plant OFF period. N.B. The setting method detailed in the example above applies equally to both SVT4201 Analogue Time Switch and SVT4251 Digital Time Switch versions of the SVT Optimiser Controller.

Issue DMS MicroSmart, Global point passing (broadcast) not working. Environment MSC-L1000 MSC- MPC-001 MSC-P-751, MSC-P-752, MSC-P-753, MSC-P-754 MSC-P-1501, MSC-P-1502, MSC-P-1503, MSC-P-1504 MSC-V-510, MSC-V-511, MSC-V-521, MSC-V-522 MSC-V-751, MSC-V-752, MSC-V-753, MSC-V-754 Cause The number of TXD and RXD broadcast channels are limited per controller type. Resolution The Level 11. controllers' MicroSmart Global Data Broadcasting capabilities are as follows: MSC-L1000: TXD and RXD on 1-122 channels MSC- MPC: TXD and RXD on 1-122 channels MSC-P-75x: TXD on 1-122 channels. RXD on 1-24 channels. MSC-P-150x: TXD on 1-122 channels. RXD on 1-24 channels. MSC-V-51x: TXD on 1-122 channels. RXD on 1-24 channels. MSC-V-52x: TXD on 1-122 channels. RXD on 1-24 channels. MSC-V-75x: TXD on 1-122 channels. RXD on 1-24 channels.  

Issue The IC3 Modbus IP interface is a client. How can this be linked to another Modbus IP client such as the Carrier i-VU gateway? Environment IC3 Modbus IP Client server Sigma Carrier I-VU Cause The IC3 Modbus only supports the IP client and cannot be directly connected to another IP client.   Other systems such as Carrier are similarly only IP client. Resolution Using the BCX1 as a Modbus IP server to hold a mapping table will allow both clients to read/write data to it.

Issue In WorkPlace Tech can a SNVT exist in a Custom Object? Environment I/A Series WorkPlace Tech 4.0 and higher. Cause Custom Object Rules Resolution Nearly all types of WP Tech shapes may be included on the Definition page of a Custom object, There are several exception and  "SNVT objects"  is one of them. This object must be on the top page of any control logic drawing instead. For  additional  exceptions see WorkPlace Tech Tool 4.0 Engineering Guide (F-27254-3), Chapter 3 "Custom Object Rules"

Issue When using DCT version 11.6, modifying the MSC-NCM schedule start-stop times do not save. The time reverts to the setting before the change was attempted. Environment MSC-NCM Cause Version 11.6 of DCT has an error in the compiled code. Resolution Instead of starting DCT from the desktop shortcut, launch it from the DCT folder (double-click DCTGL.EXE).

Issue Modify occupied cooling and heating (nciSetPts) variables on Viconics VT7652 LON stat, but changes are not transmitting to  thermostat. Have a DynamicCmd object linked up and can write the values in the DynamicCmd but they don’t ever change in the thermostat and they don’t show up in the nvoEffectSetPt variable. Environment VT7200 LonWork series VT7300 LonWork series VT7600 LonWork series Cause Setup of limits Resolution Check the HeatMaxSetpoint and CoolMinSetpoint limits found in the nciCfgRtuHP ( Vt76Pir properties). When a change that is outside of the limits, it will take the request but will not transmit change down to the thermostat.

Issue In WorkPlace Tech Tool, the Definition tab of a Custom Object, right click on any object to request Properties info. The response is an error "Exception happened finding Visio shape". What does this mean? Environment WorkPlace Tech Tool 5.7.x Cause There was an error in Visio. The custom object may have been copied from a newer version of Visio to an older version. There may have been an error when creating the custom object. Shapes may have been added to the custom object when opened directly in Visio instead of being opened in WPTech. Some other corruption to the drawing took place. Resolution Do a “Rebuild Application”, and then try opening the shape properties again.  If this does not work, try creating a new custom object, and then try copying the contents of the old custom object definition page into the new custom object definition page (while in WPTech).  Then delete the old custom object, and then try the shape properties in the newly created custom object.

Issue Unable to connect with DCT to log in MicroSmart MSC-NC Environment MSC-NC MSC-NCM MSC-DCT Cause Flash Memory got corrupted. Resolution Reloading Flash Memory on an MSC-NC (M) Power down; jump J1 (near processor); power up. Can DCT connect? If so, remove J1 jumper Do Alt-L to start Load Flash ROM installation If unable to connect with DCT, will need to consider replacing/repairing unit.

Issue Need to replace Analogue Timeswitch for Satchwell SVT4201, CSC 1776, CSC 1777, CSC2776 or CSC2777 Controller. Environment SVT4201 CSC1776 CSC1777 CSC2776 CSC2777 Analogue Timeswitch. Cause Faulty Timeswitch requires replacement. Resolution Replacement Analogue Timeswitch for Satchwell SVT4201, CSC1776, CSC 1777, CSC2776 or CSC2777 Controller is part number 561-9-260.

Issue The word TEST is displayed on the Liquid Crystal Display screen of a Satchwell Climatronic Controller when first powered up during initial installation preventing it from being commissioned. Environment Satchwell Climatronic CSC5252 CSC5352 CXR5805 CXT5605 CZT5305  Controller Display TEST LCD Screen Cause The cause of the word TEST being displayed on the Liquid Crystal Display screen of a Satchwell Climatronic Controller when first powered up during initial installation and preventing it from being commissioned is normally due to a micro processor programming error occurring during the course of production. Resolution There is no field remedy that can be applied to a Climatronic Controller displaying the word TEST on the Liquid Crystal Display screen that will enable it to be commissioned successfully. The Controller should therefore be returned to the vendor for replacement under the terms and conditions of the warranty applicable at the time of purchase.
