3 Operational Overview
The Universal Holding Cabinet (UHC) has either four slots that can hold up to three trays of product per slot
or two slots, which hold up to three trays. Each slot has a controller that indicates the holding time and
product selection for each tray position.
Universal Holding Cabinet (UHC)
The operator enters information into the controller via the display and keypad shown below. Each product
selection has a temperature setpoint and product holding time. All product timers run independently.
The
slot temperature is controlled by the temperature setpoint of the leftmost product entry in each slot as
viewed from the front of the cabinet. Product selections that have a holding temperature different that
the leftmost product selection will not be available for entry into that slot’s configuration.
Most UHC’s have a front and rear display for each slot. All operator mode selections can be made from
either display. Program changes can only be made from the front display. A
Special Point of Distribution
( SPOD ) cabinet has only a front controller for each slot.
