Abstract: A food equipment device, such as a warewasher, includes a powered component, the powered component being one of a heating element or a pump or a fan, and a power line path for delivering power to the powered component. A contactor is provided for controlling power delivery to the powered component, the contactor including main power contacts connected in the power line path and auxiliary contacts that operate the same as, or opposite to, the main power contacts. A monitoring system is operatively connected to the auxiliary contacts to monitor an open or closed state of the auxiliary contacts and includes a voltage source operatively connected to one of the auxiliary contacts and an electrical sensor for detecting one of (i) a voltage condition of the other auxiliary contact or (ii) a current flow condition between the auxiliary contacts.

Abstract: A Hall effect sensor assembly includes a tubular sleeve having an external surface portion that is threaded to facilitate mounting. A circuit board assembly has a Hall effect sensor mounted thereon. The circuit board assembly is disposed within the tubular sleeve and includes a first portion and a second portion. The first portion extends substantially lengthwise along the tubular sleeve, and the second portion extends laterally from the first portion. The Hall effect sensor is mounted on the second portion such that a sensing face of the Hall effect sensor faces one end of the tubular sleeve.
