Both reels use a coil spring that winds as you strip line. The SE typically has a refined spring geometry:
Winner: SE — smoother, more controllable. crawford automatic 100 se better
Why it happens: The original auto-tune algorithm assumes a certain thermal response time (roughly 30 seconds to 5 minutes). If your oven takes 20 minutes to stabilize, the 100 SE may oscillate. Make it better: Manually tune the PID parameters. Both reels use a coil spring that winds as you strip line
Ask any technician who has worked in plastics since the late 1990s about the Crawford 100 SE. They’ll know the key sequence to enter setup mode (press and hold the “SET” and “<” keys for 3 seconds). They’ll know that alarm 1 is usually normally open. That institutional knowledge has real value—newer controllers require retraining, which is never “better” for a lean manufacturing environment. Winner: SE — smoother, more controllable
A: The SE has a thermal cut-off switch. If the fan fails and internal temp hits 175°F, the unit shuts down gracefully and flashes a "Fan Fault" code on the LED panel. The original would simply burn out.
To understand why someone might search for “Crawford Automatic 100 SE better,” we must first acknowledge the scenarios where this old controller still outperforms modern alternatives.
