INSTALLATION ABOUT THIS MANUAL This manual contains all the information needed to configure and operate the RMB/1, RMB/2 and RMB/3 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.

A few seconds after you stop pressing an arrow button, the main display (PROC (displayed as PROCESS on RMB/1) and SETP {displayed as SETPOINT on RMB/1}) will return. 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.
This display can also be used to view and change controller settings as described in subsection 3.5. Parameters are grouped into menus. An overview of the menus is in section 3.6 If a zone is in alarm, an alarm code alternates with the SETP (displayed as SETPOINT on RMB/1) Note that the default value.
The modes available for selection are: Normal—zone uses closed-loop PID automatic control based on the entered SETP (displayed as SETPOINT on RMB/1) and measured PROC (displayed ass PROCESS on RMB/1) Standby—zone uses Standby Setpoint or Standby Percentage as configured using the Control Config menu.
— OR — — OR — is pressed to put all Idle zones in the Run state Offline—zone’s output is off and PROC (displayed as PROCESS on RMB/1) is not monitored by the controller CHANGING THE SETPOINT To change Normal mode (closed loop) setpoint or Manual mode (open loop) output percentage: 1) Select a zone or, if all zones are in the same mode (Normal or Manual), select all zones as described in section 3.2.
ALARMS AND ALARM INDICATION ALARMS TYPES OF ALARMS The RMB/X Hot Runner controllers support high and low deviation alarms, confi gurable separate- ly 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 confi gured safety limit) and problems with its own operation.

Athena’s PID (three mode) controllers are capable of exceptional control stability when properly tuned and used, allowing operators to achieve the fastest response time with the smallest overshoot.
Autotune to work, the difference must be at least 9 F (5 The startup curve (change in PROC, displayed as PROCESS on RMB/1) was not acceptable to the Autotune algorithm. This problem could be caused by a process upset that occurred during tuning. Try Autotuning again when the process is stable.
Autotuning. Manual tuning requires that zones be tuned one at a time and that the PROC (displayed as PROCESS on RMB/1) be tracked over time. (Graph the displayed PROC (displayed as PROCESS on RMB/1) against time manually.) All zones should be running while manually tuning one zone.
4) Choose “Disable” or “Enable” by pressing 5) Exit the menu system by pressing and holding until the standard operating display (PROC (displayed as PROCESS on RMB/1) and SP) is displayed.
SETP and PROC are displayed. Alternatively, select all zones by pressing until all zones’ RMB/1 Jump to step SETP and PROC are displayed with asterisks between the values for the zones. 3) Access the menu system by pressing until a menu name is displayed, and then press repeatedly until the name of the Superv Confi...
