Tachometers monitor belt slip and feed four-leg magnetic amplifier which controls conveyor drive relay K2. If tachometer outputs do not match because of belt slip or belt failure, bridge becomes unbalanced, magamp output decreases, and K2 drops out.-F. R. Hulscher, Fail-Safe Circuits for Conveyor Sys tems, Electronics, 32:28, p 60.
