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: Control may automatically start Manual, Timer, or Profile mode
based on a preset time and day.
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.
High-Limit temperature readout is provided on LCD 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 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.
Power LED: Indicates that power is supplied to the instrument.
Heater LED: Indicates that the heater output is active.
Profile LED: Indicates that the Profile Mode is in operation.
Timer LED: Indicates that the Timer Mode is in operation.
Manual LED: Indicates that the Manual Mode is in operation.
Cycle Complete LED: Indicates that the control is in Stopped mode.
Hi-Limit Alarm LED: Indicates that the high limit relay has tripped
(de-energized).
Soak Alarm LED: Indicates that the guaranteed soak deviation is in alarm
condition.
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,
high limit temperature, 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.
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.
Retransmission: The retransmission output is a DC 1 to 5 volt or 4 to 20 ma
(DC) signal that is proportional to the process temperature. The signal can be an
input to other devices such as a chart recorder.
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.

Profile #
There are eight profiles available.
Segment#
Recipe segments 1 through 8 may be programmed, each with its own
set of events, ramp and soak times, and soak temperature.
Ramp Time
The time required to ramp from one setpoint up to another setpoint.
Values between 0 and 99:59 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.
EV1 through 4
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).

Soak Time
The duration of soak is entered here; the value can range from 0 to
99:59.
EV1 through 4
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
installed and programmed for an event.
Hi Limit SP
The high limit setpoint may be entered here; if the temperature
exceeds this value, the hi-limit will alarm and shut off the heater.
Loop From
Values are No, Seg-1 to Seg-8.
Loop To
Values are No, Seg-1 to Seg-8.
Loop Number
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.
Profile Link
Values are STANDBY/STOP/HOLD/1 - 8. When the profile ends, the
profile can hold the temperature setpoint while keeping the events
active, turn the heater off, hold the temperature setpoint at the end of
the profile, or jump to another specified profile.
Guaranteed
Soak Band
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.

key to restore factory
Press the Page key to exit the Zone Calibration Page.
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).

Conversion and Optional MRC5000
Setup
Temperature Scale Conversion (C/F)
The Protocol Plus controller can be operated in either C or F. The default setting for the
controller is C. Changing from one to the other is as follows:
1. Go into the Setup Mode on the controller.
2. Press the Select Key until Setup is displayed.
3. Press the Page key and Security will be displayed.
4. Press the Menu Key and Password will be displayed. Use the arrow keys to
enter the proper password. The default password is 2 for level two.
5. Once the proper password is displayed, press the Page key until PID is
displayed.
6. Press the Menu key and Temp Unit along with C or F will be displayed. Use the
arrow keys to change the setting.
7. Once the proper setting is displayed, press and hold the Page key for
approximately three seconds to exit the Setup Mode.

Optional MRC5000 Recorder Setup
The temperature is retransmitted to the Recorder from the Controller. Set up the
Recorder as follows:
1. Make sure that jumper JU1 is setup for the 5 VDC setting (see MRC Manual).
2. Move the Mode switch to the PROG/TEST/CAL position, and Prog will be
displayed.
3. Press the down arrow key twice and Inps will be displayed. Make sure the
settings are per the table below.
4. Once all the settings have been changed, move the Mode switch to the RUN
position. The display on both the Recorder and controller should read the same.

Depending on the equipment, 0 - 600 paper can be used if the maximum
temperature is 500 degrees F.
** Note:
These values must mach the setting sRetOutLo and RetOutHi on the
Control page on the Protocol Plus controller (example: RetOutLo is 32,
then EUL must read 32).
