Theory of Operation
2.1. Protocol Manager Software
The Despatch Protocol Manager network utility software
enables the operation of up to 32 Protocol 3
and/orProtocol Plus controllers from a single, remote PC.
Protocol Manager software allows:
Remote access and operation of one or more Protocol
3 and Protocol Plus controllers
Use of a centralized PC to store and edit profiles
Download the same profile to multiple controllers
Upload a profile from a particular controller to the
central PC for use in other controllers
Centralized data logging from all controllers connected
to the central PC
Password security
Use this Instruction Manual in conjunction with the Protocol 3
and Protocol Plus
Controller Owner’s Manual.
2.2. The Protocol 3 Controller
The Protocol 3™ is a microprocessor based digital temperature controller designed for simple
and flexible oven operation (Figure 2). The Protocol 3 controller operates as a dual-functioning
controller/High Limit instrument. The control portion utilizes a time-proportioning voltage signal
to control heating devices with minimal temperature fluctuations.
The Protocol 3 controller provides three primary operating modes:
Manual: Oven operates continuously at a fixed temperature until turned off.
Timer: Oven operates at a fixed temperature for a user-selected time period, and then
automatically turns off.
Profile: Temperatures increase or decrease as defined by 255 segments that can be allocated
to 64 ramp and soak profiles. The profiles can be linked to provide additional temperature
combinations.
Review the Protocol 3 Controller Owner’s Manual for more information.
