Chapter 5: Maintenance 5.10 Loss of Connection If the T20 pendant ever loses connection to the SmartController EX motion controller for any reason (e.g. controller reboot), a Connection Lost screen will be displayed. From this screen, pressing OK will tell the pendant to try to reconnect to the controller. Figure 5-5. Connection Lost Screen If the reconnection fails, use the ACE software to verify that the controller's monitor window is responsive. If this state persists, contact your sales representative for assistance. 5.11 Cleaning To clean the T20 pendant, use a soft cloth dampened with a small amount of water or a mild cleaning agent. CAUTION:
Never clean the T20 pendant display screen or other sur- faces with solvents, abrasive cleaners, or scrubbing sponges. 5.12 Periodic Maintenance Periodically check the protective covers of the T20 pendant to ensure that all housing screws are firmly tightened, and that there is no damage to the cable entry area, sealing plug, or cable strain-relief.
