OPERATING YOUR CONTROLLER
1) Assuming that all zone power and thermocouple are
correctly in place, turn on the controller using the power
switch on the back. The controller will complete its
startup sequence, and 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
If the controller has already been wired to the sensors

until after you have confi gured the zones and entered
customsetpoints.
When zones are taken out of Idle, their outputs may go
on (check default parameter values).
2) Take unneeded zones out of service by setting them
to Offl ine.
a) Select a zone by pressing the zoneselection button
until only that zone’s PROC and SETP are displayed.
(Zone numbers are shown next to the row of status LEDs
for eachzone.)
b) Access the mode-selection function by pressing the
mode/ enter button
Access the mode-selection function by pressing the
.
c) Step through the possible modes by pressing
the mode/enter button repeatedly until “Offl ine” is
displayed.
d) Exit the mode-selection function by pressing the
menu- access/exit button
Exit the mode-selection function by pressing the
. A confi rmation will be
displayed briefl y and then the PROC and SETP for the
zone will be displayed as“OFF.”
3) The green F (for Fahrenheit) or C (for Celsius)
LED is lit; indicating the scale being used. If you want to
change the temperature scale:
a) With any zone selected, press and hold the menu-
access/ exit button
With any zone selected, press and hold the menu-
until the name of a confi guration
menu is displayed.
b) Step through the menus by pressing
repeatedly until the Display Confi g menu name is
displayed.
c) To access the Display Units parameter, press
The scale will alternate with the parameter name on the
lower line of the display. An asterisk is displayed instead
of a zone number to indicate that the parameter applies
to allzones.
d) Press or to change the temperature
scale
e) Exit the menu system by pressing and holding
for several seconds and the PROC and SETP for all
zones (except any offl ine zones) will be displayed in the
new selected scale. Any temperature values previously
entered will be converted automatically.
A row of LEDs for each zone indicates statuses for the zone and its output. These status icons are:
output: lit green when the zone’s output is on
boost: lit green when the zone is in Boost mode
closed loop: lit green when the zone is in a closed loop mode, such as Normal, Closed Loop Boost, Normal Soft Start,
etc.
open loop: lit green when the zone is in an open loop mode, such as Manual or Open Loop Boost
standby: lit green when the zone is in Standby mode or Hardware Standby mode
alarm: flashes red when the zone is in alarm
Buttons provide access to all controller functions. The purposes of the buttons are shown below.

Silence alarm button - silence time is con-
fi gurable
Increase setpoint and upward scroll
through parameter values button

4) If the factory settings 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 PROC and SETP are displayed.
To select all zones, press
that zone’s PROC and SETP are displayed.
repeatedly until the PROC
and SETP for all zones are displayed with asterisks
between zone displays. This last step is relevant for the
model RMB/1
b) Press and hold to enter the menu system.
c) Step through the menus by pressing
to enter the menu system.
repeatedly
until the menu you want isdisplayed.
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.
5) Change Normal mode (closed loop) setpoints or
Manual mode (open loop) output percentage by selecting
a zone, and then pressing
Manual mode (open loop) output percentage by selecting
or
Manual mode (open loop) output percentage by selecting
to change the
setpoint or output percent. A few seconds after you stop
pressing an arrow button, the main display (PROC and
SETP) will return.
6) Autotune all zones that will operate in Normal
(closed loop) mode. 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:
for Normal (closed loop)
for Manual (open loop)
forStandby
If the zone is confi gured to start up in Idle after the run/
idle button
If the zone is confi gured to start up in Idle after the run/
has been pressed, no status LED will be
lit.
Whenever a zone’s output is on, its green output LED
is lit.
INTRODUCTION
Athena’s single zone RMB/1 Hot Runner
controller can provide microprocessor-based
control of one zone; the RMB/2 provides the
same control for two zones, and the model
RMB/3 for three zones. Zones can be
confi gured individually or all zones can be
confi gured 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 confi guration
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
