4848B Reactor Controller User’s Responsibility All Parr Reactors and Pressure Vessels are designed and manufactured with great care to assure safe operation when used within their prescribed temperature and pressure limits. But… the basic responsibility for safety when using this equipment rests entirely with the user; who must: 1. Select a reactor or pressure vessel that has the capability, pressure rating, corrosion resistance, and design features that are suitable for its intended use.
4848B Reactor Controller Installation General Instructions Set the controller on a sturdy bench or table where there is convenient access to an electrical outlet with the appropriate supply voltage and current ratings in accordance with national and local electrical code requirements. Leave a space of at least twelve inches between the controller and the heater of the reactor so that the controller will not be affected by radiant heat.
4848B Reactor Controller Component Summary Switches and Indicators Front Side 4848B Reactor Controller The Heater Switch is a manual, three-position, illuminated switch which controls the amount of power sent to the heater. In the HIGH (II) position, full power is developed by the heater. In the middle (0) position the heater is off. In the LOW (I) position, a diode is switched into the system to allow only onehalf of the rated voltage to be supplied to the heater.
4848B Reactor Controller Back Side 4848B Reactor Controller Protective Fuses and Relays An instrument fuse is mounted on the back panel. This is a Fast-acting, 250VAC, 1.0 amp fuse, intended to protect the temperature control module and any installed display modules. The motor reset/motor fuse provides overload protection for 0-90VDC motors. This is a re-settable breaker designed to protect the motor if it becomes overloaded. The breaker will have a rating selected to match the motor on the apparatus.
4848B Reactor Controller Thermocouple burnout protection is included in each of these controllers. If the thermocouple should burn out, or if there is a break in the thermocouple circuit, power to the heater will be shut off. In most cases this will cause the controller to show a “NO CONT” reading. A similar high reading will be displayed if the controller is turned on without an attached thermocouple. In either of these situations, the high limit reset will activate.
4848B Reactor Controller Instructions for the 4848B Reactor Controller Caution! Check that controller settings are set to factory defaults before operating for the first time. The default settings are listed at the back of this manual. Note: Controller parameters can be found in Appendix A on page 24 of this manual. Temperature Control Module been reached, the High Limit Reset will trip, cutting power to the heater, and the ALM light will illuminate indicating a High Limit was activated.
4848B Reactor Controller b. The parameter displayed is the group in use with exception of PID4. When PID4 is set, the PID parameters will automatically switch between PID groups 0, 1, 2 and PID group 3, depending on which group’s SV best matches the current temperature (PV). c. All of PID parameters in the group can be obtained from auto-tuning or they can be set manually. When manually entering PID values into a particular group, the SV for that group can be manually entered as well. Autotuning 1.

The upper display will read [SP00], where the “00” represents the pattern and step number, respectively. The lower display will indicate the set point for indicated step. The set point can be adjusted using the arrow keys then press the set key to solidify the change.

4848B Reactor Controller Pressure Display Module (PDM) 2. Press the set button. The lower display will stop blinking, showing the new value has been set. PRESSURE When this optional module is present, the left display in red shows the pressure, and the right hand display in green shows the Pressure Alarm setpoint. If the reactor pressure exceeds this setpoint, the pressure module will trip the High Limit Alarm, cutting power to the heater.
4848B Reactor Controller Motor Control Module (MCM) RPM When this optional module is present, the left display in red shows the stirring speed, and the right hand display in green shows the rpm setpoint. The 4848B Controller is designed to run in either Local or Remote stirring mode. The local/remote switch on the front panel will toggle between these two modes. In Local mode, the stirring speed is controlled by turning the speed control knob on the front panel.
4848B Reactor Controller External Heater Temperature Limit Control Module (ETLM) TEMPERATURE ETLM This module should be considered in systems with large thermal lags or long dead times such as gas phase reactions or other systems where temperature control is difficult. This configuration is similar to the High Temperature Cut Off Module (HTM), but the display will now turn off the heater if it exceeds a pre-set adjustable setpoint.
4848B Reactor Controller 4848B Controllers furnished as a part of a complete Parr stirred reactor system will have the proper resistor installed at the factory. Any controller sold separately will require a motor specification so that the proper resistor may be provided. Always turn the speed control knob fully counterclockwise to the off position before turning on the motor switch, then advance the knob clockwise slowly to develop the desired speed. Do not overload the motor.
4848B Reactor Controller Communication with PC The 4848B Controller is provided with RS-485 port (labeled comm) and may be connected to a USB port on a PC with optional A1925E4 communication cable. Quick Start Instructions for Connecting with PC 1. Put the 576M CD into the CD-ROM. 2. Connect the A1925E4 communication cable between the comm port on the back of the 4848B Controller and an open USB slot on the PC. 3.
4848B Reactor Controller Datalogging and Charting The 4848B Controller comes equipped with a charting and datalogging program. This program cannot be run simultaneously with the control program, but once the user is satisfied that the controller is set, the control program may be closed, allowing the charting and datalogging program to run. The modules on the 4848B may still be modified manually at the physical panel during datalogging and charting. 7. 1. Open the ParrCom.exe file.
