System Control
A Despatch Protocol Plus controller/high-limit device is used to control the unit. This is
located on the control panel of the oven. See the section on the Protocol Plus controller
for detailed operation.
The Protocol Plus controller provides temperature control for the process.
The Protocol Plus controller provides outputs for the cooling/exhaust fan, and
door lock switch/door release pushbuttons.
As many as eight (8) profiles for oven heating cycles are stored in the Protocol
Plus controller. These are accessed by the operator using the Protocol Plus
keypad.

follows:

Yellow (pilot light)
– Cycle On
Green (illuminated push button)
– Cycle Complete (depress push button after
unloading and sterile door closed)

Optional MODBUS RS422/485 serial communications hardware may be installed
on the Protocol Plus controller, with two 9-pin communications ports located on
the front of the oven. This provides the ability to network the oven(s) with a host
