iB6 Operating Display
iB12 Operating Display
1.1 About this User Guide
This user guide contains all the information needed to configure and operate the iB6 and iB12
Integrated Temperature Controllers.
Wiring diagrams, mounting instructions and other information about installing the hardware are on
the installation diagrams shipped with the unit.
1.2 iB6 & iB12 Features and Benefits
1.2.1 Multi-Zone Control with Convenient User Interface
A single iB6 Temperature Controller can provide microprocessor-based control of up to six zones;
a single iB12 Hot Runner controller can control up to twelve zones. Zones can be configured
individually or all zones can be configured simultaneously.
During operation the front panel simultaneously displays the process value and setpoint for every
zone. LEDs for each zone indicate the type of control (open or closed loop), output status, alarm
status, boost status and standby status. Buttons on the front panel make it easy to change the
setpoint, mode and configuration parameter values for one selected zone or all zones.
The front panel also has buttons to:
• start the boost for all zones,
• put all zones in Idle or all Idle zones in the Run state,
• silence the audible alarm.
When necessary, access to function buttons on the front panel can be restricted.
Refer to Section 7. for details on how to enable or disable functions.

1.2.2 PID Control with Autotuning
When an iB6 or iB12 zone is in Normal (closed loop) mode, Proportional-Integral-Derivative (PID)
control is provided. The iB6 and iB12 Temperature Controllers also support Manual (open loop)
mode that overrides automatic control. In Manual mode you control the output by entering a fixed
output percentage value.1A zones transfer from PID to manual is “bumpless” when the process
value is within 5 °C (9 °F) of the setpoint.
Using PID control, the controller modulates output power by adjusting the output power
percentage within a configurable proportional band. Power is proportionally reduced as the
process temperature gets closer to the setpoint temperature.
The configurable derivative action affects the output based on the rate of change of the process
value.
The integral action affects the output based on the duration of the process value’s variation from
the setpoint. In the iB6 and iB12 Temperature Controllers, the integral (reset) action is always
equal to six times the configured derivative (rate) action.
An Autotune function is standard on every iB6 and iB12 Temperature Controller. This feature
for easy tuning of the proportional and derivative, components of the control algorithm can be
initiated every time the controller is powered up, once when the controller is set up regardless
of success (and again by changing a parameter value), once only if successful (repeated at each
power up until successful), or never.
Instructions for tuning the controller automatically and manually are in Section 6.
1.2.3 CompuStep®Soft Start for Heater Bake Out
All iB6 and iB12 Temperature Controllers support the CompuStep®soft start feature, which
allows slow dissipation of moisture in heaters by gradually applying power to the heaters. Using
this feature helps extend the life of the heaters and the moulds. When a soft start is executed,
single cycle bursts start at 5% output power and step up the output 5% every 30 seconds.
• The soft start when the controller is in Normal (closed loop) mode lasts five minutes or until
the process temperature reaches 93 °C (200 °F).
• The soft start when the controller is in Manual (open loop) mode continues until the output is
the lower of 50% or the target Manual mode output percent.
By default, a soft start will be executed:
• Every time the controller starts (after being taken out of Idle) and the process value is less
than 93 °C (200 °F), and
• Every time the controller is returned to Normal (automatic) operation and the PV is less than
93°C (200 °F).
1.0 Introduction
1Use of a fixed output percentage is also possible under other circumstances. Configuration parameters let you specify a fixed
output to be used as a failsafe action, a different fixed output percentage to be used in standby mode, and another fixed output
percentage used during the boost function described in 1.2.4.

Temperature ControlleriB6 / iB12
1.0 Introduction
1.2.4 Programmable Boost Function
Every iB6 and iB12 Temperature Controller supports a boost function. For each zone you can use
the Boost Config menu to configure a special setpoint (closed loop boost) or a special fixed output
percentage (open loop boost) to be used when the boost button is pressed.
The boost function will remain active until:
• the configured boost duration time has expired, or
• you use the mode/enter button to take a zone out of boost mode before the expiration of the
boost duration.
1.2.5 Process-Protection Features
Process-protection features are standard on all iB6 and iB12 controllers.
These features include:
• high and low deviation alarms
• high temperature safety limit
• loop break detection
• failsafe operation in case of sensor problems
1.2.6 Security
The iB6 and iB12 front panels include buttons that can be used to change the selected zones setpoint
and mode and to boost the output temporarily by a configurable amount. Users who know the
Supervisor password can limit access to these buttons on the front panel, plus limit configuration
access. (Units are shipped with password protection disabled.)

1.0 Introduction
1.4 What Happens When You Power Up the Controller
When an iB6 or iB12 Temperature Controller is powered up using the switch on the back, all
LEDs and all elements in the LCD display light briefly, and then software versions (of the display
and the controller hardware) are displayed.
At the conclusion of the startup process, the process values and setpoints for all zones are
displayed. Only the green LED for the display unit of measure (Celsius or Fahrenheit) is lit.
All zone outputs will be off because the unit starts up with all zones in the Idle state.
Briefly pressing the run/idle button on the front of the case puts all zones that are currently
Idle in the Run state. (Pressing the button again for at least two seconds puts all zones in Idle.)
In each zones column of LEDs, the green LED in the closed loop or open loop row is lit to
indicate the type of control.
The green LEDs in the output row indicate whether the zones outputs are on (LED lit) or off.
For more information about the user interface, see the Section 3.
When zones go into the Run state, the effect on each zones output depends on the value of the
Startup Mode parameter configured using the Control Config menu.
Refer to 5.4 for Startup Mode parameter details

2.0 Setup Sequence
2.1 Setup Sequence
The following list summarises the configuration and startup tasks to be accomplished once the
controllers are wired as shown on the diagrams shipped with the unit.
Refer to Section 5 for information about all configuration parameters, parameter interactions and valid ranges.
1) Turn on the controller using the switch on the back (shown below). When the unit is powered
up, the controller goes through its startup sequence (see 1.4), and then the process value and
setpoint for every zone (the standard operating display) are shown. All zones will be Idle (all
outputs off).
If the controller has already been wired to the sensors and heaters, do NOT push the run/idle
button on the front of the case until after you have configured the zones and entered custom
setpoints. When zones are taken out of Idle, their outputs may go on unless you change the
default parameter values.
2) Take unneeded zones out of service by setting them to Offline.
a) Select a zone by pressing the zone selection button until only that zones
PV and SP are displayed. (Zone numbers are above the column of status LEDs
for each zone.)
b) Access the mode-selection function by pressing the mode/enter button .
c) Step through the possible modes by pressing the button repeatedly until “Offline”
is displayed.
d) Exit the mode-selection function by pressing the menu-access/exit button .
A confirmation message will be displayed briefly and then the PV and SP for the zone will
be displayed as “OFF.”
3) Notice that the green C (for Celsius) or F (for Fahrenheit) LED is lit. This LED indicates the unit of
measure for the process values and setpoints displayed.
If you want to change the unit of measure used for temperature displays:
a) With any zone selected, press and hold the menu-access/exit button until the name of
a configuration menu is displayed.
b) Step through the menus by pressing repeatedly until the Display Config menu name is
displayed.
c) To access the Display Units parameter, press . The currently selected unit of

for all zones (except any offline zones) will be displayed in the selected unit of measure.
Other temperature values previously entered while a different unit of measure was in use
will be converted automatically.
4) If the factory settings listed in subsection 3.6 are not appropriate for your application, you can
change a parameter value for one or all zones.
a) To select one zone, press repeatedly until only that zones PV and SP are displayed.
To select all zones, press repeatedly until the PV and SP for all zones are displayed
with asterisks between the PV and SP for zones 3 and 4 (refer to the image below) on
an iB6 unit. (On an iB12 unit, asterisks will also be displayed between the PV and SP for
zones 9 and 10.)
b) Press and hold to enter the menu system.
c) Step through the menus by pressing repeatedly until the name of the menu you want
is displayed.
d) Step through the menu items by pressing until the parameter you want is displayed,
alternating with its current value.
e) Change the value by pressing or . When changing a numerical value, you can hold
down an arrow button for fast changes.
f) Exit the menu system by pressing and holding for several seconds.
Note that the default High [Temperature] Safety [Limit] (a Supervisor parameter) is Off
by default. If you want the controller to turn off the output to a zone that exceeds the high
limit, change the value of the High Safety parameter.
5) iB6 and iB12 units are shipped with the Supervisor password set to 100, which disables
password protection. If you want to limit access to the Superv [Supervisor] Config menu, change
the Supervisor password from the default 100. As long as the password is 100, no password will
be required to access all functions (except settings on the Factory Config menu).2
6) Change Normal mode (closed loop) setpoints or Manual mode (open loop) output percentage by
selecting a zone, and then pressing or to change the setpoint or output percent. A few
seconds after you stop pressing an arrow button, the main display (PV and SP) will return.
Tip: If all zones are in the same mode (Normal or Manual), you can select all zones as described
above, and then change the setpoint temperature or manual mode output percentage for all
zones simultaneously.
7) Autotune all zones that will operate in Normal (closed loop) mode; see Section 6. When
Autotuning has been completed successfully for all Normal zones, the controller is ready to use.
The appropriate green status LED in the column of LEDs for each zone will be lit:

4.0 Alarms & Alarm Indication
4.1 Types of Alarms
The iB6 and iB12 Temperature Controllers support high and low deviation alarms, configurable
separately for each zone (see subsection 5.6). The unit also recognises process problems (such as
loop break, reversed and open sensors, and process temperature exceeding configured safety limit)
and problems with its own operation.
4.2 Alarm Indication
When a zone is in alarm:
• its red alarm LED flashes rapidly (Slow flashes mean an alarm was detected, but the problem
does not affect operation now. For example, a zones red alarm LED flashes slowly if an open
thermocouple is detected, but the zone is operating in Manual mode (in which no sensor value is
used by the controller to calculate the output)
• the alarm relay closes
• a code for the type of alarm alternates with display of the setpoint (Normal mode or other closed-
loop mode such as closed-loop boost) or output percentage (Manual mode or other open-loop
mode such as open-loop standby); and
• unit beeps until the alarm condition is cleared or the zone is put in Idle mode or the alarm is
silenced (refer to Section 4.3 below).
4.3 Silencing Alarm Beep
You can temporarily silence the alarm beep by pressing the alarm silence button . Beeping will be
