SAFETY Protocol Plus Owner’s Manual

Danger!

10 Version 2

2. Safety

2.1. Safety Information

Do not wo rk on the Protocol Plus 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 t he Protocol Plus controller into a zero energy state and prevents accidenta l machine start up. Always follow the Lockout Proced ur e descr ibed in this Section before cleaning, maintaining or repairing the Protocol Plus controller. An accidenta l start-up, while working on the Protocol Plus cont roller, can result in serious inju ry or death.

2.1.1.1. Lockout Requirements

1. Every power source that can energize any element o f the Protocol Plus controller

must be shut off at the closest po ss ible pow er source. This includes air, water and electricity, includ ing the Disconnect Switch.

2. After energy sources ar e locked out, test to ensure circuits are de-energized.

2.1.1.2. Lockout Procedure with Despatch Products

Personnel author ized to lockout equipment must have the necessar y locks to perform the lockout.

1. Physically disconnect all electrical power to the machine or lockout the appropriate

breaker or disconnects.

2. Close all valves and bleed off any pressure.

3. Test for power by attempting a start with the machine co nt ro ls.

4. Identify the Lockout Condition with a tag on the elect r ical disconnect and p neu matic

shut of f valve .

5. When work is complete, remove all tags and restore the machine to its wo r king state.

Electric a l pa ne ls contain high volt age. Disconnec t a nd loc k o ut the power supply before working inside any electrical panels. Failure to lock out the power supply can result in death or injury.

Danger!

Version 2 11

2.2. Maintenance

Only qualified and trained personnel should perform maintenance or repair.

2.3. Electrical Power

Only qualified and trained personnel should perform electrical maintenance or electrical repair.

• Before performing maintenance, disconnect all electrical power from the machine.

Use a padlock and lockout all disco nnect s feeding power to the machine.

• Never clean or repair the controller whe n in op eration.

• Unauthorized alterat ions o r mod ifications to Protocol Plus controller are str ictly

forbidden. Never mod ify any electr ica l circu its. Unaut ho rized modifications can impair the fu nction a nd sa fety of the Protocol P lus controller.

Contact with energized electrical sources may result in serio us injury or death.

2.4. Fire

2.5. Equipment Lockout Requirements

Keep the Protocol Plus controller clean and free of scrap mat er ials, oil or solvents to pre vent the p ossibility of fire . In the e vent of fire, us e a fir e extinguisher as follows.

1. De-energize the machine immediately by pushing an Emergency Stop push button

2. Turn off the remote main disconnect (customer supplied disconnect).

3. Extinguish the fire.

Always disconnect all power before extinguishing a fire. Attempting to extinguish a fire in a machine connected to electrical power can result in serious injury or death!

To prevent injury or equipment damage during inspection or repair, the Protocol Plus controller must be locked out.

THEORY OF OPERATION Protocol Plus Owner’s Manual

Figure 1. Operator Interface.

12 Version 2

3. Theory of Operation

The Protocol Plus is a modular micro pr ocessor based digital te mperatu r e cont roller (Figure 1). The Protocol Plus controller operates as a dualfunc tioning controller/high limit instru ment. The control po rtion u tiliz e s a time -pr oportioning voltage signal to control heating devices with minimal tempe rature fluctuations.

The h i gh limit portion protects the product and /or the oven from overheat ing. If the product being processed has a critical high te mperat ur e limit, t he high limit setpoint should be set to a temperatur e somewhat below the temperature at which the product could be damaged. If the product do es not ha ve a critical high te mperat ur e limit, t he high limit set p oint s ho uld be set 5 to 15 degrees higher tha n the maximum programmed setpoint at w hich the ove n will operate.

Th e Prot oc ol Plus controller provides three primary operat ing modes:

• Manual: Oven operates cont inuously at a fixed temperature until turned off.

• Timer: Oven operates at a fixed temperatu r e for a user-selected time period, then

automatically tu r ns off.

• Profile: Temperat u r es increase o r d ecr ease as defined by one of eight pre-

programmable ramp and soak profiles. Each pro file co nt ains up to eight r amp and soak segments. The profiles can be linked to provide additional temperatur e combinations.

In addition these primary operating modes, the Protocol Plus controller employs a Stopped Mode, Auto Start Mode, Setup Mode and Fast Start Mode:

• Stopped Mode: All control and relay outputs are off. Stopped Mode is integrated

into each of the modes of operat ion.

• Aut o Start Mode: C ontrol may au tomat ic ally star t Manual, Timer, or Prof ile

mode based on a preset time and day. Optional event outputs can be util ized during Manual, Timer, or Profile modes.

• Setup Mode: Provides access to control configuration and programming of

profiles. Set u p Mod e contains ten separate electronic “Pages” where con figuration and programming para meter s (Menu items) are found and can be manipulated .

• Fast Start Mode: Pro vides for automatic startup of an operating mode w hen

po w er is applied. Use Fast St art Mo d e if the same mode of operation is used every day. The user can turn on the power and the oven w ill start t he desired process automatically. The Fast Start Mode is controlled by the Power-Up St a rt parameters o n the Control page.

Protocol Plus Owner’s Manual THEORY OF OPERATION Version 2 13

3.1. System Control—In Ge ner a l

• T he Proto col Plus controller provides outputs for the cooling fan, door lock

switch/door release pus hbutton, and optional beacon lig ht

• As many as eight profiles for oven hea ting cycles are stored in the Proto col Plus

controller. Access profiles using the Protocol Plus keypad.

• The Prot oco l Plus cont r ols the solenoid valves in an in ert atmosphere oven for p urg e

and maint ain operat ion

3.1.1. High-Limit Function

The Protocol Plus controller has an integ rated h igh limit function which d is able s the heater output when t ripped. Find High-Limit temperature readouts on LC D Line #2 in all Modes (Stop, Run, Hold, and Standby) except Setup Mode. High-Limit temperature is displayed for 10 seconds, alternating with current Mode and Status display for 10 seconds. The contro l will not allow t he high limit set point to be set below the current setpo int value.

If the high limit trips, the Hi-Limit indicator w ill light and the relay must be ma nu a ll y reset. Allow the o ven to cool several degrees (or increase t he high limit set point) and then press Reset. The indic ator will turn of f.

3.1.2. Optional Serial Communications Hardware

Optional MODBUS RS422/485 serial communications hardware may be installed on the Protoco l Plus controller, with a 9-pin communicatio ns port located on rear of oven. This provide s the a bility to netwo rk the oven(s) with a host PC.

3.2.

Display Functions

The Protocol Plus contro ller has t wo displa ys. A dedicated LED upper display shows t he oven temperatur e (Figure 2). A two line LCD lower display provides information on control stat u s, high limit temperat ur e and a llows changes to be made to the control settings. Figure 3 shows a schemat ic of the Protocol Plus face plate.
