Pneumatics troubleshooting gets easier

摘要

A newly developed pneumatic-control system provides basic valve operation, as well as de-Jailed monitoring of electrical solenoids, sensors, wiring, and connections. Called Drive Diagnostic Link (DDL), the system checks that every valve's supply voltage is within acceptable tolerances, solenoid coils operate properly, and instantly pinpoints short circuits. And should it detect a fault, the control system displays appropriate text messages to alert operators and service technicians, often before a failure occurs. Checks are carried out as soon as a machine is switched on and continuously as it runs, ensuring the pneumatic subsystem operates properly at all times. By integrating "intelligence" with the control system, DDL makes it easier to use diagnostic capabilities with Bosch Rexroth pneumatic systems. And better diagnostics means better response to impending problems, permitting proactive maintenance with less downtime and, ultimately, higher productivity and reliability.
