Conclusion
Universal Application
Field configurable safety timings allow the technician to choose from 15, 30 or 45 second lockout timing through the control interface.
Offers only a 15 second fixed safety timing
Truly universal - A single control covers most of the installed base.
Access to Diagnostic Information and Control Setup
Technicians can quickly access the setup menu and diagnostic information through the built-in LCD display.
An additional snap on display, handheld tool or docking station is required to setup timings and access the diagnostic information
No additional specialty tools required
Diagnostic Information
Provides the technician with the cause for lockout on the digital display allowing them to quickly troubleshoot and repair the system
Presents the technician with a data log requiring them to decipher the information to determine the actual cause of the problem
Points the technician towards the source of the problem, not to a data log i
Much more than adding a display to the control!
