LF Programmer 11902F1 2-Cam Timer for Professional Appliances

A mechanical programmer with two cams governs the operating cycles of professional catering appliances. The cams rotate at a fixed speed, each lifting and lowering a switch lever in sequence. One cam sets the start of a cycle, the other its end, allowing the appliance to run for a precise interval without manual supervision. This method delivers consistent timing without electronics, making it suitable for high-temperature or high-moisture environments where digital controls might fail.

The operator sets the desired duration by rotating the cams to align their lobes with the switch levers. Once the appliance is powered, the cams turn continuously, closing and opening the switches in the programmed order. The first cam closes its switch to start the cycle; the second cam opens its switch to stop it. The interval between these two events is the programmed run time, which remains constant until the cams are reset.

This programmer is constructed as a sealed unit with a metal housing and mechanical linkages. The cams and switch levers are enclosed to protect them from dust, grease and moisture common in professional kitchens. The housing is designed to mount directly into the control panel of compatible appliances, replacing worn or damaged original programmers without modification.

The two-cam design allows a single programmer to control two distinct phases of an appliance's operation, such as pre-heat and cooking, or defrost and reheat. Each cam operates independently, so the duration of each phase can be set separately.

This programmer fits specific models of ELETTROMECCANICA CDC and PIRON commercial appliances. It is listed in the spare-parts catalogue under timers and programmers for mechanical control systems.
