Issue The OnSite Stat Controller can read temperature values, but the system does not control outputs. The SS light on the Site Stat Controller Interface is not flashing. Product Line Andover Continuum Environment Andover Continuum Stat Controller Cause A field wiring error occurred. The temperature sensor was incorrectly wired with x1 and x2 terminations reversed. Resolution Verify the wiring of the temperature sensor. Ensure x1 and x2 terminations are correctly connected. Once corrected, the controller resumes normal operation and the SS light flashes as expected.

Issue Users upgrading from older Continuum versions (e.g., v1.62) need to confirm whether LCX898 and ACX781 Infinet controllers are still supported in the latest version (v2.03). Product Line Andover Continuum Environment CyberStation Continuum versions 1.62 through 2.03 LCX898 and ACX781 Infinet controllers Cause The controllers are either in limited production or no longer manufactured, raising concerns about compatibility during system upgrades. Resolution LCX898 and ACX781 controllers are supported in all CyberStation versions from v1.62 to v2.03. No chip change or hardware modification is required for compatibility. Ensure proper configuration and testing after upgrade to maintain system stability.

Issue When communication is lost to an AC1 module, doors lock down even if they were previously unlocked by schedule. Product Line Andover Continuum Environment AC1 modules Cause The AC1 module is designed to fail to a secure position when communication is lost, ensuring security during network or controller failures. Resolution This behavior is intentional for security purposes. When communication is lost, AC1 modules automatically lock doors to maintain a secure environment. To prevent unexpected lockouts, ensure redundant communication paths or monitor module connectivity.

Issue Older sites still have ACX781 controllers installed, but the cabinet keys are missing. Users want to know if replacement keys can be ordered. Product Line Andover Continuum Environment ACX781 Cabinet Enclosure Cause The ACX781 controller was discontinued in 2007, and the stock of cabinet lock/key assemblies has been depleted. Resolution Replacement cabinet keys for ACX781 controllers are no longer available. If access is required, consider replacing the cabinet lock with a standard lock assembly from a local hardware supplier. For long-term support, plan to upgrade to current-generation controllers.

Issue Users want to configure an ACX57xx controller to use its RS-485 Infinet communication port to connect to a Netcontroller as an Infinet device, similar to older ACX781 controllers. Product Line Andover Continuum Environment ACX5720 ACX5740 Cause The ACX57xx was designed to replace and improve upon the ACX781, requiring higher bandwidth for enhanced features such as: Increased memory Faster processor Larger personnel storage Secure communications The Ethernet LAN provides this bandwidth, whereas the Infinet network would create a significant bottleneck. Resolution The RS-485 port on ACX57xx can be configured for Infinet communications only to add subnet controllers off the ACX57xx. It cannot be configured to communicate directly on the Infinet network as a slave device. For full functionality and performance, the ACX57xx must connect via Ethernet LAN.

Issue After creating an output point on an XPD02 expansion module connected to a BCX controller, the output does not function. The CPU LED on the XPD02 remains solid ON. Product Line Andover Continuum Environment XPD02 Expansion Module BCX Controller Continuum system with expansion modules Cause The XPD02 was connected to the BCX while the system was powered, which can cause communication or initialization issues. Resolution Reload the BCX controller to reinitialize communication with the XPD02.

Issue The ACX57xx controller intermittently stops granting access through doors. The controller operates normally for a period but then ceases to grant access until it is reloaded. Replacing the controller does not resolve the issue. Product Line Andover Continuum, EcoStruxure Building Operation Environment ACX5740 ACX5780 Cause A single power supply is being used to power both the controller and the door strike outputs, which can lead to voltage drops or interference affecting controller performance. Resolution Install the ACX57xx controller according to the ACX57xx Controller Installation Instructions, ensuring separate and adequate power supplies for the controller and strike outputs.

Issue What is the maximum allowable cable length for the Continuum I/O bus when connecting IOU modules? Product Line Andover Continuum Environment IOU Modules Continuum I/O Bus RS-485 and FTT-10A network configurations Cause Cable length impacts signal strength and integrity. Longer cables cause signal loss and distortion, which can lead to communication failures. Resolution Follow these maximum cable length specifications for the Continuum I/O bus: RS-485: 2000 ft (610 m) FTT-10A: Double termination: 8858 ft (2700 m) Free topology: 1640 ft (500 m) Ensure proper termination and topology to maintain reliable communication.

Issue Older Continuum access controllers (CX9900, CX9702, ACX700, ACX781) only support one card credential per user locally. When the system is configured for dual credentials, these controllers cannot store the second credential, leading to unexpected access behavior. Product Line Andover Continuum Environment CyberStation CX9900, CX9702 ACX700/1, ACX780/1 Dual credential configuration Cause Older controllers lack the capability to store two credentials per user. CyberStation does not distribute the second credential to these controllers, causing reliance on remote validation. Resolution Enable remote validation on older controllers by setting the Access Server system variable to the ACCNetId of the primary access server (any value in the range 191–254 works, but use the primary server for consistency). Explanation: When the second credential is presented at a door managed by an older controller, the controller sends a remote validation request to the access server. Access is granted or denied based on the server response. Note: Changing Allowed Credentials in CyberStation does not affect older controllers. They will continue granting access to credential 1 until reloaded.

Issue When assigning a schedule to a personnel area located in a different Continuum network than the door, the schedule does not function as expected. Product Line Andover Continuum Environment ACX5740 ACX5720 Continuum Access Control systems with multiple networks Cause Objects cannot be passed between different Continuum networks. A schedule linked to a personnel area assignment must reside in the same network as the door that uses the area. Resolution Ensure that the schedule is located in the same network as the door requiring the area assignment. Best Practice:Place schedules within the controller for the door. This ensures that if the controller goes offline, the schedule will still operate correctly.

Issue Users need access to the Declaration of Conformity (DoC) documentation for Andover Continuum hardware to meet regulatory compliance requirements. Product Line Andover Continuum Environment Continuum controllers and devices Regulatory compliance documentation Cause The location of the Declaration of Conformity documentation is unclear, making it difficult for users to find the required compliance certificates. Resolution The Declaration of Conformity documentation for Andover Continuum hardware is available through Regulatory Compliance on mySchneider Steps to Access: Navigate to mySchneider. Search for “Andover Continuum Declaration of Conformity” Download the relevant certificate for your hardware.

Issue What keypads are supported by ACX781 controllers? Product Line Andover Continuum Environment ACX781 Controller Access control systems requiring keypad input Cause The ACX781 controller circuitry only supports 3x4 matrix dry contact keypads. It does not support Wiegand keypads or voltage matrix keypads such as “2 of 7.” The reference to “2 of 7” in the ACX781 cutsheet is incorrect. Resolution Use a keypad that supports the 3x4 matrix dry contact interface, such as: Essex Keypad HID model 5355AGS00 If you require Wiegand keypads, you must upgrade to a controller that supports Wiegand, such as: ACX57xx series CX9900 + AC1 CX9680 + AC1

Issue The Error LED on ACX780 or ACX781 controllers is illuminated. Users want to know: Is the LED linked to the Errors system variable? What conditions trigger the LED? How can the error be cleared? Product Line Andover Continuum Environment ACX780 ACX781 Continuum access control system Cause The Error LED is associated with the controller’s Errors system variable. A non-zero value typically indicates an internal issue, most commonly a disabled program within the controller. Resolution Use Command Line or CyberStation to check the Errors system variable. If the value is non-zero, investigate and correct the underlying issue (e.g., re-enable disabled programs). To clear the LED, set the Errors system variable back to 0 after resolving the cause. Note: Simply resetting the variable without fixing the root cause may result in the error reappearing.

Issue How to print a Control Backslash (CTRL\) character from a PE program in Continuum systems. Product Line Andover Continuum Environment Continuum PE(Plain English) Cause The PE device driver expects an escape sequence starting with CTRL\ followed by a specific code. Without this sequence, the output will not be interpreted correctly. Resolution The following line will send the expected esc sequence followed by the value of the Minute system variable out of comm1 (assuming the port is already opened for printing): Print "|28", Minute to comm1

Issue Users encounter Runtime Error 312 when attempting to access the embedded webpage of controllers such as NC2 and BCX. Product Line Andover Continuum Environment Embedded Webpage NC2 Controller BCX Controller ACX B4 Warning Potential for Data Loss: The steps detailed in the resolution of this article may result in a loss of critical data if not performed properly. Before beginning these steps, make sure all important data is backed up in the event of data loss. If you are unsure or unfamiliar with any complex steps detailed in this article, please contact Product Support for assistance. Cause The error occurs due to malware present on the PC accessing the embedded webpage. Resolution Run a full virus scan on the PC. If the virus scan does not successfully remove the malware, format and reinstall the operating system to ensure the PC is clean.

Issue When ordering a bCX1 controller (models 9640 or 4040), the number of controller nodes displayed on the options page is one more than the ordered quantity. Product Line Andover Continuum Environment bCX1 9640 bCX1 4040 Cause All bCX1 controllers include one additional node beyond the ordered quantity. This extra node is reserved for connecting a RoamIO device to either the MS/TP or Infinet network. Resolution The additional node is intentional and allows the RoamIO to connect to the network. When designing a system, always leave one node available for RoamIO. Example: An 8-node controller supports up to 9 nodes. A 32-node controller supports up to 33 nodes. If all nodes are used, offline editing may be required to add the last node.

Issue When an active video event appears in the Video Monitor interface during an alarm, the events disappear after closing the Video Monitor. Users cannot locate or replay these events later. Product Line Andover Continuum Environment Andover Continuum 1.91 and above Cause This behavior is by design. The system does not store video event lists for historical access. Resolution Video events are only available while active in the Video Monitor interface. Historical video event lists are not saved in the system. To search and replay recorded videos based on alarm events, use the Continuum Video Inquiry add-on application.

Issue During the installation of Microsoft SQL Server 2005, the process appears to hang for an extended period, particularly at the “Setting File Security” step. Product Line Andover Continuum Environment Microsoft SQL Server 2005 Cause This is a known Microsoft issue. Under certain conditions, the installation process stalls while setting file security due to network-related factors. Resolution Disconnect the machine from the network before starting the installation. This typically allows the process to complete quickly. Alternatively, apply the cumulative hotfix provided by Microsoft to resolve this issue.

Issue Users need to install Continuum or webClient but do not currently have the security key connected to the PC. Product Line Andover Continuum Environment Continuum webClient Cause The installation process does not require the security key; however, the application cannot run without it. Resolution Yes, you can install Continuum or webClient without the security key connected to the PC. The security key is required only to run Continuum Cyberstation or the webClient server after installation. Ensure the key is available before attempting to start the application.

Issue ACCDataServices crashes when starting CyberStation or during normal operation. Product Line Andover Continuum Environment CyberStation Cause Windows permissions issues Windows Firewall configuration Mixed CyberStation versions (e.g., 1.94 and 1.94 SP1) Heavy resource usage on standalone systems Third-party BACnet devices flooding trend logs Resolution Step 1: Software Updates Do NOT mix 1.94 and 1.94 SP1 CyberStations on the same database Install CyberStation 1.94 SP1 or greater 2.03 is the most current version and Upgrade controller firmware to the most recent Step 2: Installation Requirements Ensure user has Local Admin rights during CyberStation installation. Turn Windows Firewall OFF during installation. (Open ports Disable VirusScan software during installation (Turn on during normal operation) Step 3: Event Notifications Avoid unnecessary recipient options (Pager, Log, Forward, etc.) to reduce traffic. Check enhanced alarm delivery in Database Initialization > Server (or Stand Alone). Examples of unnecessary recipient options Step 4: Action-Object Mapping Ensure each Event notification action (e.g., Display Graphic) has a corresponding object for point alarming. Step 5: Stand-Alone Cyberstation Systems Heavy resource usage when extended logging, graphics, SQL Server, CyberStation run together can contribute to errors Eliminate Windows error log issues and disable certain functions like graphics to see if that feature contributes to the errors Consider server-class PC for demanding sites Step 6: Third-Party Devices Disable/unplug 3rd party BACnet devices or disable their trend logs Step 7: Liebert Sitelink Versions 1.93 and below: Bacnet trendlogs may affect Continuum by flooding data Upgrade to 1.94 or greater and disable trend logs Step 8: Diagnostics Run acctrace, Continuum error log, Windows application log and Wireshark to detect errors. Use Windows application logs, system info Reference Article: Top 10 Steps for Troubleshooting Cyberstation and webClient issues
