RMB/6 and RMB/12 Hot Runner Controller Configuration and Operation Manual
1.Introduction
1.1 About this Manual
This manual contains all the information needed to configure and operate the RMB/6 and
RMB/12 Non-Modular Hot Runner controllers.
Wiring diagrams, mounting instructions, and other information about installing the
hardware are on the installation diagrams shipped with the unit.
1.2 Features and Benefits of RMB/6 and RMB/12 Controllers
1.2.1 Multi-Zone Control with Convenient User Interface
A single RMB/6 Hot Runner controller can provide microprocessor-based control of up to
six zones; a single RMB/12 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. See
Section 7for details.

RMB 12 Operating Display
1.2.2 PID Control with Autotuning
When an RMB/6 or RMB/12 zone is in Normal (closed loop) mode, Proportional-Integral-
Derivative (PID) control is provided. The RMB/6 and RMB/12 Hot Runner 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 zone’s transfer from
PID to manual is “bumpless” when the process value is within 9 °F (5 °C) 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 RMB/6 and RMB/12 Hot Runner controllers, the
integral (reset) action is always equal to six times the configured derivative (rate) action.
An Autotune function is standard on every RMB/6 and RMB/12 Hot Runner 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 RMB/6 and RMB/12 Hot Runner 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 molds. 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 200 °F (93 °C).
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.

RMB/6 and RMB/12 Hot Runner Controller Configuration and Operation Manual
•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 200 °F (93 °C), and
•every time the controller is returned to Normal (automatic) operation and the PV
is less than 200°F (93 °C).
1.2.4 Programmable Boost Function
Every RMB/6 and RMB/12 Hot Runner 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 RMB/6 and RMB/12controllers. 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 RMB/6 and RMB/12 front panels include buttons that can be used to change the
selected zone’s 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.)

RMB/6 and RMB/12 Hot Runner Controller Configuration and Operation Manual
1.4 What Happens When You Power Up the Controller
When an RMB/6 or RMB/12 Hot Runner 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 (Fahrenheit or Celsius)
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 zone’s 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 zone’s output depends on the
value of the Startup Mode parameter configured using the Control Config menu. See 5.4
for details.

2.Setup Sequence
The following list summarizes the configuration and startup tasks to be accomplished
once the controllers are wired as shown on the diagrams shipped with the unit.
Information about all configuration parameters, including parameter interactions and valid
ranges, is in Section 5.
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 zone’s
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 F (for Fahrenheit) or C (for Celsius) LED is lit. This LED
indicates the unit of measure for the process values and setpoints displayed.
Units ordered for the “Domestic Market” (see model number breakdown in
subsection 1.3) are set to display temperatures in degrees Fahrenheit. Units
ordered for “Export” or “CE” are set to display temperatures in Celsius.
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

This asterisk indicates that the parameter applies to all zones.
d) Change the unit of measure by pressing or .
e) Exit the menu system by pressing and holding for several seconds. The
PV and SP 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 zone’s 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 (s

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) RMB/6 and RMB/12 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

4.Alarms and Alarm Indication
4.1 Types of Alarms
The RMB/6 and RMB/12 Hot Runner controllers support high and low deviation alarms,
configurable separately for each zone (see subsection 5.6). The unit also recognizes
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 zone’s
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 (see below).
4.3 Silencing Alarm Beep
You can temporarily silence the alarm beep by pressing the alarm silence button .
Beeping will be silenced for the configured number of seconds. (The default is 120
seconds.)
4.4 External Indication
An output on the back of the controller allows external devices (such as horns or lights) to
be connected to the controller for alarm annunciation. For more information about this
feature, see the diagrams shipped with the controller.
This alarm output is not affected when the alarm silence button on the front of the
controller is pressed.
