We are using the double-solenoid valves that were included in the kit of parts in previous years. (I believe they are made by SMC.) We are extremely sure that the valves are not wired backwards because we switched the connections for each solenoid across the various outputs on the Solenoid Breakout and only some of the outputs worked consistently. The other outputs appeared to never work at all, although their corresponding lights on the Solenoid Module would illuminate. We are toying with the idea that the Solenoid Module and/or Breakout is damaged. At this point we probably don't have time to get another Solenoid Breakout and Module so we moved the four non-working solenoid groups onto spike relays and are doing them the "old school" way. Is there a way to test out Solenoid Module and Breakout system? If one of these components are damaged, how can we get replacements and are they covered under any warranty? Are there any rules or regulations that would disallow the use of spike relays with the SMC double-solenoid pneumatics valves?
