Unparalleled Safety Features

Safety system questions are at or near the top of any electrical or computer controlled mobile system evaluation chart.  The LOGICPlus™ controller provides the most comprehensive array of safety alternatives ever offered.  Historically unreliable and repair intensive approaches such as activated flooring, mechanical plungers and mechanical sweeps have been replaced with complete interface to all leading safety tape and photo sweep systems.  The LOGICPlus™ controller is designed to interface with today’s most advanced PIR infrared systems and digital photographic aisle monitoring systems.  

In addition to the safety system alternatives discussed above, every LOGICPlus™ controller features two more “designed in” safety systems. First is the Passive Block System (PBS), which is activated after carriage movement with no requirement for actions by system users. Following completion of the aisle opening, the system will remain immobile until the PBS is deactivated.  Deactivation requires the next storage system user to remove the system block by pressing the previously activated controller keypad identified by an indicator light.  PBS is preferred in mobile systems being used by the general public or in any system where any user training is not feasible.  The second “designed in” safety feature is the Motor Current Monitoring System (MCMS).  Every LOGICPlus™ controller contains logic to actually monitor the current being utilized by the motor and detect even a minute change. This change in current drawn may be caused by even slight pressure against a moving carriage or additional weight placed on a moving carriage.  When a change in current being drawn is detected by the MCMS, an Emergency Stop command is issued by the LOGICPlus™  controller and carriage movement ceases.





 

The LOGICPlus™ system design will allow it to be fully compatible with future safety systems as developed by LOGICPlus™ or others.  As a result owners of mobile systems utilizing the LOGICPlus™ controller will never have to sacrifice enhanced user safety to avoid system obsolescence or total system replacement.   
 

System Security
 

As the use of mobile aisle systems for storing valuable, sensitive, or private documents and materials has increased, so have the concerns about system security. Two commonly employed security approaches have been carriage keys, which are subject to duplication, or punch in pass codes that can be passed from one person to another.  As a result, users have had to settle for unsatisfactory system security and in many cases even forego the benefits of mobile storage systems due to security considerations..  Again the innovative design of the LOGICPlus™ controller has made the security problems of the past, just that, problems of the past.  By using the One Touch function adjustment transponder, access to the system can be limited by aisle and by user.  The individually identifiable transponder cannot be copied or passed to an unauthorized user. The system security privileges can be revoked or modified due to employee change, reassignment, or system reconfiguration by simply changing the computer security authorization spreadsheet and downloading the new security privileges to the appropriate One Touch transponders.  The LOGICPlus™ controller means no system downtime for security modifications, no costly refitting, no compromised security.

System Reliability and Durability 

Early electrical and computer controlled mobile storage systems were forced to employ mechanical devices in their control panels, stopping distance control mechanisms and safety systems.  Surprisingly most mobile system manufacturers continue to utilize these inexpensive but unreliable moving part based mechanisms.  As a result system users are constantly confronted with costly repairs and replacements often preceded by a time and resource-consuming search for a supplier of a now out of production part.    As stated earlier, a design requirement for the LOGICPlus™ controller was a level of system durability not seen before.  The controller employs analog distance sensors that control carriage spacing and allow for no-shock stopping with no moving parts.  The Big Button touch panel employs no mechanical or moving parts, and the use of a 24V DC carriage motor allows for non-jerk starting and stopping to dramatically reduce motor wear.
