Issue Customer did a full backup of a SIGNAL 4.4.1 installation.  A full backup is data, bitmaps, and executable files.  The computer hardware was replaced along with the operating system to Windows XP 32-bit.  The customer has SIGNAL version 5.0.0. Environment SIGNAL Cause Computer hardware replacement Resolution There are a couple of ways to restore the database.  Here is a simple method: - Install SIGNAL 5.0.0 - Restore the full backup from version 4.4.1 (this step overwrites all the executable files of 5.0.0) - Re-install SIGNAL 5.0.0 (this last step will update all the executables back to version 5.0.0) The license file, signal.dcf, may need to be checked to ensure it is for version 5.0.0.

Issue Information on how the MNB-Vx determines damper position after a power cycle. Environment MNB-V1 and MNB-V2 Cause Understanding damper behavior after a power cycle Resolution After a power cycle, the damper does not know exactly where it is and it is NOT stored in non-volatile memory. So, it must drive open or drive closed to re-synch the hall effect sensors embedded in one of the gears that provides positional feedback. There are two Hall-Effect sensors that detect a magnet, embedded in one of the drive gears, as it spins. Each sensor sends a pulse to an internal counter each time it detects the passing magnet. The two Hall-Effect sensors help with identifying clockwise and counter-clockwise rotation. The accumulated pulse count and the gear ratio help in calculating the damper position. Right-click the VAV Actuator object in WorkPlace Tech and go to its Properties, there is a setting called 'Position Initialization Mode'. Select open or closed as the choice when initializing after a power cycle.  

Issue A newly added Microzone II does not appear in the Node List in PSI.  The ASD trunk contains existing controllers connected to a UNC-520.  All existing ASD controllers appear in the Node List.  Environment Niagara R2 ASD Cause The new ASD controller must be 'learned' into the R2 station in order for it to appear in the Node List in PSI. Resolution Access the R2 station and use Device Manager to find and learn the new controller into the station. 

Issue Do we have a replacement for the Fire Rated Damper Actuator: Make: Siebe Environmental Controls Part No: MA – 223   Environment Fire Rated Smoke actuators MA-223-0-2 Cause Siebe Fire/ Smoke rated damper actuators are all obsolete. Resolution Schneider Electric no longer manufacture any fire and smoke actuators so the MA-223 range are obsolete with no replacement. The only suggestion we can offer is for the customer to contact the damper manufacturer that this actuator is mounted on and see what they would use to replace the actuator. We only sold these fire/smoke rated actuators directly to the damper manufacturers.

Issue What are the expected voltages on the RS485 IO Module bus? Product Line Andover Continuum Environment Netcontroller IO Modules IOU Modules Cause Require typical values for troubleshooting first steps. Resolution Although the IO Module bus uses RS485 comms similar to Infinet or BACnet MSTP, the typical bus voltages when measured with a voltmeter are usually lower. Exact voltages will vary from system to system and depend on the amount of bus activity at the time, but the following will allow general troubleshooting: Typical DC voltage measured across the bus + to - = 0.7 to 0.8VDC but working systems may read as low as 0.4VDC Typical DC voltage measured Screen (shield) to + = 0.6 VDC Typical DC voltage measured Screen (shield) to - = 1.3VDC Note: If using Free Topology (FTT-10A) controller and modules, these use transformer bus coupling and will measure 0VDC across the bus.

Issue Alarm Manager configuration. Environment Alarm Manager Configuration Cause A different configuration of alarms is required on a Remote Sigma client. Resolution The Alarm Manager is shared by both the local and remote Sigma clients, therefore any changes in configuration effect both clients. If there is a requirement to send different alarms to the local and remote Sigma clients, then this is achieved using Routesets, which are allocated to the individual object alarms.
