Marlen Smart Tech
Case Study #1
The customer had issue reported as excessive residual air in the product. We reviewed the unit product inlet valve, loading into the sleeve/piston area, and performed a static vacuum test. After 15 minutes use of the Smartech device, we were able to verify our pump/hopper system was not the root cause of their issue and allowed them to move trouble-shooting downstream. If the plant were to attempt these checks without the visual confirmation we may not have been able to confidently eliminate our components resulting in a service call of 2500-3000.00. At a minimum, there would have been several phone calls. With the plant personnel walking to and from the machine would have been at least an hour or longer.
Case Study #2
A unit had failed to start (COV portioner). The main fuse had blown. Upon starting the Smartech, it was immediately found the e-stop switch had broken. Water had entered the broken switch and shorted the 24VDC system. 5 minutes on the Smartech device, issue was identified. It would have been much longer without the visual aid using a volt meter to find shorted wires due to looking inside the machine's cabinet where the circuitry resides.
Case Study #3
At initial installation of a Smartech system, it was noted by the production supervisor the line was slow for pieces per minute. We reviewed the portion fill speed, sleeve/piston loading, and piston speed. The issue was identified as slow piston speed. We opened the hydraulic enclosure to check signal at the hydraulic valve (speed by-pass) and no light was present. Opening and checking the PLC found a fuse blown for this valve. We tested the coil and found it had failed. Replacing the valve coil solved the issue and normal production speeds were achieved. Total time to identify the issue was 20 minutes. Each of the checks, with a mechanic walking to and from the unit, would have taken approximately 1.5-2.0 hours plus the time walking back and forth from the mechanics room to make phone calls for next steps.
