Protocol 3 Controller Owner’s Manual Version 1.2 2. Safety 2.1. Safety Information Do not work on the Protocol 3 controller without reading and understanding this section which contains important information and warnings. Ignoring these warnings can result in death, serious injury or damage to the machine and product. 2.1.1. Lockout Machine lockout places the Protocol 3 controller into a zero energy state and prevents accidental machine start up.
PAGE 14
Protocol 3 Controller Owner’s Manual Version 1.2 SAFETY 14 2.3. Electrical Power Only qualified and trained personnel should perform electrical maintenance or electrical repair. Danger! Contact with energized electrical sources will result in serious injury or death.    Before performing maintenance, disconnect all electrical power from the machine. Use a padlock and lockout all disconnects feeding power to the machine. Never clean or repair the controller when in operation.
PAGE 15
Protocol 3 Controller Owner’s Manual Version 1.2 3. THEORY OF OPERATION 15 Theory of Operation The Protocol 3 is a microprocessor based digital temperature controller designed for simple and flexible oven operation (Figure 1). 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. Figure 1. Operator Interface.
PAGE 16
Protocol 3 Controller Owner’s Manual Version 1.2 THEORY OF OPERATION 16 3.1.2. Outputs The Protocol 3 controller comes standard with an output signal that can transmit temperature data, setpoint data or control power to a user-supplied recording device. Output relays (five) can also signal user-specified events or alarm to external devices (Figure 2 and Figure 3).

Protocol 3 Controller Owner’s Manual Version 1.2 ASSEMBLY & SETUP 18 4. Assembly & Setup Danger! All grounding and safety equipment must be in compliance with applicable codes, ordinances and accepted safe practices. Warning! Disconnect the main power switch or power cord before attempting any repair or adjustment. 4.1. Install the Protocol 3 Controller When replacing a Protocol 3 controller, follow the steps below.
PAGE 19
Protocol 3 Controller Owner’s Manual Version 1.2 ASSEMBLY & SETUP 19 4.3. Setting Up Remote Communication Remote communication between the Protocol 3 controller and a PC running the Despatch Protocol Manager software involves providing each controller with a unique address and following the communication protocol procedures. Up to 32 separate controllers can be run from a PC running the Despatch Protocol Manager software. See the Protocol Manager Instruction Manual for the complete set-up procedure.

Protocol 3 Controller Owner’s Manual Version 1.2 WORKING WITH OPERATING MODES 52 5.6.1.5. Glossary of Alarm Terms Term Description Alarm Hysteresis Alarm hysteresis is the deadband on the safe side of an alarm (that is, the side of the alarm that is below the high alarm value or above the low alarm value). The signal must pass through this deadband before the alarm deactivates. Alarm Inhibit prevents unwanted process or deviation alarm activation at powerup or when the controller setpoint is changed.
