INTRODUCTION

The special features of the Protocol PlusTM control include:

• PID tuning

• Ramp/Soak programming of up to 64 segments

• Segment looping and profile linking

• Built-in manual reset high limit control

• Built-in process timer

• Dedicated LED display for process temperature

• Multi-purpose two-line LCD display with backlight

• Auto-tuning

• Security access

• Digital inputs for remote profile control

• Optional relay outputs for events, alarms, or end-of-cycle signal

• Optional real-time-clock

• Optional RS232/RS422/RS485 MODBUS communications

Theory of Control Operation

The Protocol Plus is a modular microprocessor based digital temperature controller. The
Protocol Plus 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 high limit portion protects the product and/or the oven from overheating. If the
product being processed has a critical high temperature limit, the high limit setpoint
should be set to a temperature somewhat below the temperature at which the product
could be damaged. If the product does not have a critical high temperature limit, the
high limit setpoint should be set 5 to 15 degrees higher than the maximum programmed
setpoint at which the oven will operate.

Operating Modes

The Protocol Plus control has five modes of operation available:
Stopped Mode: All control and relay outputs are off. Stopped Mode is integrated

into each of the following four modes of operation.

Manual Mode: Control operates as a single setpoint control until Stopped mode is

accessed

Timer Mode: Control operates as a single setpoint control until preset time period

has expired.

Profile Mode: Control operates as a ramp/soak profiling control until the end of

the profile. 8 profiles are available with up to 8 ramp/soak segments
in each profile.

Auto Start Mode (optional): Control may automatically start Manual, Timer, or

Profile mode based on a preset time and day.
Requires the optional real-time clock feature.

The optional event outputs can be utilized during Manual, Timer, or Profile modes.

Setup Mode

The control has a Setup Mode which provides access to control configuration and
programming of profiles. The Setup Mode contains ten separate electronic Pages where
the configuration and programming parameters (Menu items) are found. The Setup
Mode Pages are described in detail elsewhere in this manual.

Fast Start Mode

The Protocol Plus control has the ability to automatically start an operating mode when
power is applied. This feature may be useful if the same mode of operation is used
everyday. The user can turn on the power and the oven will start the desired process
automatically. The Fast Start Mode is controlled by the Power-Up Start parameters on
the Control page (see Setup Mode).

3

High Limit

The control has an integrated high limit function which will disable the heater output
when tripped. If the high limit does trip, the relay will need to be manually reset. When
the high limit relay is tripped, the Hi-Limit indicator will be lit. Allow the oven to cool
several degrees (or increase the high limit setpoint) and then press the Reset key. The
indicator will turn off.

The control will not allow the high limit setpoint to be set below the current setpoint
value.

Indicators

The Protocol Plus control has 12 indicating LEDs that provide operational information to
the user.

C Power LED: Indicates that power is supplied to the instrument.
C Heater LED: Indicates that the heater output is active.
C Profile LED: Indicates that the Profile Mode is in operation.
C Timer LED: Indicates that the Timer Mode is in operation.
C Manual LED: Indicates that the Manual Mode is in operation.
C Cycle Complete LED: Indicates that the control is in Stopped mode.
C Hi-Limit Alarm LED: Indicates that the high limit relay has tripped (de-energized).
C Soak Alarm LED: Indicates that the guaranteed soak deviation is in alarm

condition.

C Outputs 1 through 4: Indicate that the optional relay outputs are in the ON state.

These outputs may be configured as timed event outputs, process temperature trip
point outputs, alarm outputs, or as an end of cycle relay output. The ON state can
be configured as energized or de-energized.

4

Displays

The Protocol Plus control has two displays. A dedicated LED upper display shows the
oven temperature. A two-line LCD lower display provides information on control status
and allows changes to be made to the control settings.

Key Functions

The Protocol Plus control has seven keys that provide operation.

• Select key: Press to select mode of operation. In Setup Mode, to select profile
number or relay. In Profile/Run Mode, press simultaneously with the UP key to
advance a segment.

• Run/Hold key: Press to activate a mode of operation. If a Profile (or Timer)
Mode is running, pressing the Run/Hold key will place the Profile (or Timer) in
Hold status. A subsequent press will resume the Profile (Timer).

• Stop key: Press to stop any mode of operation.

• Page/Reset key: While in Setup Mode, press to access different Pages of

configuration, Press this key to silence an alarm if the instrument alarm sounds
during operation. In an operating mode, if an alarm or error condition occurs,
press this key to return the instrument to normal operation once the condition is
cleared.

• Menu/View key: While running any operating mode, pressing this key will
display the high limit setpoint. While in Setup Mode, pressing this key will provide
access to each Menu parameter.

• keys: Press these keys to adjust parameter settings. In Profile/Stopped
Mode, press to select profile to run. In Profile/Run Mode, press key
simultaneously with the Select key to force the program to advance one
segment.

5

Outputs

The Protocol Plus control has seven different outputs available.

• Heating output: The control output is a DC voltage open-collector output which
is time-proportioned and designed to control a heat control device such as a solid
state relay.

• Cooling output: The cooling output is a 4 to 20 ma DC output which is designed
to control a cooling device such as a damper motor.

• High limit: The high limit output is a form C relay which is energized under
normal operating conditions. If the control senses a temperature higher than the
high limit setpoint, or if there is a sensor error, the high limit relay will de-energize
until the condition is cleared and the Reset key is pressed. When the high limit
relay is de-energized, the heater is disabled.

• Relay (four optional outputs): The four form A dry contact relay outputs can be
configured to function as alarms, events, or end of cycle. These outputs can be
utilized in Manual, Timer, or Profile Mode.

Recipe segments 1 through 8 may be programmed, each with its own
set of events, ramp and soak times, and soak temperature.

The time required to ramp from one setpoint up to another setpoint.
Values between 0 and 59:59 are allowable. In the Protocol Plus
controller, the profile ramp and soak times are stored without units.
Units are set as either hours and minutes (HH:MM) or minutes and
seconds (MM:SS). The setpoint will automatically increment from the
actual temperature to the soak temperature.

From 1 to 4 events may be programmed into the ramp time portion of
each segment here. These typically involve actuating/disabling relays
to close/open valves or perform other relay-controlled functions.
NOTE: These will only actuate when the controller has the relay cards
installed and programmed for an event.

The temperature setpoint of a particular segment is entered here; it
can range from -18 to 540 degrees C (0 to 1000 degrees F).

The duration of soak is entered here; the value can range from 0 to
59:59.

From 1 to 4 events may be programmed into the soak portion of each
segment here. These typically involve actuating/disabling relays to
close/open valves or perform other relay-controlled functions. NOTE:
These will only actuate when the controller has the relay cards

Values are No, Seq-1 to Seq-8.
Values are No, Seq-1 to Seq-8.
Values are 0 - 99.

These values enable the operator to jump from a certain step to
another step of the recipe a preset number of times.

Values are STOP/HOLD/1 - 8. When the profile ends, the profile can
turn the heater off, hold the temperature setpoint at the end of the
profile, or jump to another specified profile.

If the process temperature deviates from the setpoint by more than
this value, the soak timer is placed in a hold condition. The timer
continues when the process temperature falls within range.

Zone Calibration Page

The Zone Calibration Page allows adjustment of the displayed temperature versus the
actual temperature measured by the control thermocouple. This may be desirable in
certain conditions where the center of the oven chamber is not the same temperature as
the control thermocouple. This may occur when the oven is not allowed to soak at a
constant temperature for long periods of time, or the oven is being used at high
temperature.

There is also a Factory Calibration Recovery which will restore the factory calibration
values when the control was first shipped by the manufacturer. This may be helpful if
the calibration has been lost and a calibration instrument is not readily available. To use
the Factory Calibration Recovery feature only, bypass the Zone 1 and Zone 2
calibration parameters by pressing the Menu key.

To access the Zone Calibration Page, enter the Setup Mode (see description earlier in
this manual). Press the Page key until Zone Cal is displayed. Press the Menu key. Each
parameter can be changed by pressing the Menu key until the desired parameter is
displayed, and then pressing the keys to change the value.

Two points of display calibration (temperature offset) are available. The Zone 1 Actual

and Zone 2 Actual parameters are the two temperature points where the offset is to take
effect. These values are adjustable. The Zone 1 and Zone 2 Displayed parameters are
the values the user wishes to have displayed at the Actual temperatures, and are also
adjustable.

24

As an example, the control is displaying 400°F with the setpoint being 400°F, but the
center of the oven chamber is actually 395°F. This can occur due to oven wall losses
and product loading variations. The operator may change the zone calibration so that
the center of the oven is 400°F when the display reads 400°F. In this case operate the
oven in manual mode with a setpoint of 400°F. Record the center of the chamber (as
measured with an independent sensor). Access the Zone Calibration Page and enter
this measured value as the Zone 2 Actual value, with 400° as the Zone 2 Displayed
value.

Zone 1 can be adjusted using the same method at a lower temperature. The instrument
will then create a linear offset based on the Zone1 and Zone 2 Actual temperature
values. Note that the oven does not have to be heated to adjust the zone parameters if
the zone values are known based on prior experience.

25

Sensor Calibration Page

The Sensor Calibration Page has parameters which can change the internal calibration
of the temperature sensor input signal. There is a low and high calibration point for both
the control sensor and the high limit sensor. To calibrate the instrument, allow the
control to warm up for at least 30 minutes.

To access the Sensor Calibration Page, enter the Setup Mode (see description earlier in
this manual). Press the Page key until Control Sensor is displayed. Press the Menu
key.

The control may have the optional process value retransmission output feature. The
output is a 1 to 5VDC signal. To calibrate the retransmit signal, the RetOutLo and
RetOutHi values from the Control Page must be known. You may bypass calibrating
the control and high limit sensor input to access only the retransmit calibration by
pressing the Menu key until RetCalLo is displayed (skip steps 4-17).

To re-calibrate the instrument:

1. Disconnect the control and high limit sensor thermocouples.

2. Connect a calibration instrument with a type J thermocouple output to the
control sensor input. Allow the control to warm up at least 30 minutes.

3. Access Setup Mode.

4. Press Page key until -100F is displayed.

thermocouple, -100 degrees Fahrenheit output.

7. Wait 30 seconds. Press the key.

8. With Ctrl Sens 1400F displayed, adjust the calibration instrument to 1400
degrees Fahrenheit output (Type J thermocouple).

9. Wait 30 seconds. Press the key.

10. When the control displays Ctrl Sens Done, disconnect the calibration
instrument from the control sensor input and connect it to the high limit sensor
input. Reconnect the control sensor thermocouple.

11. Press the Menu key until HL Sens -100F is displayed.

12. With the control displaying HL Sens -100F, adjust the calibration instrument
to -100 degrees Fahrenheit output (Type J thermocouple).

13. Wait 30 seconds. Press the key.

14. With the control displaying HL Sens 1400F, adjust the calibration instrument
to 1400 degrees Fahrenheit output (Type J thermocouple).

15. Wait 30 seconds. Press the key.

16. When the control displays HL Sens Done, disconnect the calibration
instrument from the high limit sensor input. Re-connect the high limit sensor
thermocouple.

17. To skip calibration of the retransmit signal, press the Page key twice to exit the
Sensor Calibration Page.

18. To calibrate the retransmit signal, press the Menu key until RetCalLo is
displayed.

26

19. Connect a calibration instrument with a type J thermocouple output to the
control sensor input.

20. Connect a voltage measurement device to the retransmit output terminals.

21. Set the calibration instrument output to the temperature value of the RetOutLo
parameter from the Control Page.

22. Adjust the RetCalLo * value using the keys until the voltage measurement
device reads 1VDC.

23. Press the Menu key.

24. Set the calibration instrument output to the temperature value of the RetOutHi
parameter from the Control Page.

25. Adjust the RetCalHi * value using the keys until the voltage measurement
device reads 5VDC.
