  • Page 9: Safety Information

    How to Use This Manual The Operation and Service Manual describes how to operate, configure, calibrate, maintain and troubleshoot the Model RPC30 Room Pressure Controller. The manual is divided into two parts. Part one describes the unit and how to interface with the device. This section should be read by users, facilities staff, and anyone who requires a basic understanding of how the device operates.

  • Page 11: User Basics

    Part One User Basics This section is designed to provide a brief but thorough overview of the product installed. These few pages explain the purpose (The Instrument) and the operation (Useful user information, Operator panel, Alarms) of the product. Technical product information is available in Part Two of the manual.

  • Page 12: Display Screen

    Figure 2. Two Room Screen Display Screen The LCD display is highly configurable and can display various critical information including pressure differential, flow rate, alarm status, menu options, and error messages. In addition, the LCD display is used for programming the unit. When programming the unit, the display will show menus, menu items, and current value of the menu item, depending on the specific programming function being performed.

  • Page 13: Usb Port

    USB Port There is a USB port on the case. This USB port can be used with TSI’s Configuration Software. Figure 3. USB Port Location Alarms The Model RPC30 controller has visual (red light) and audible alarms to inform you of changing room conditions.

  • Page 14: Alarm Relays

    Alarm Relays The PresSura controllers feature 2 alarm relays. The alarm relays can be field configured to either open or close to indicate an alarm condition, although they will close on loss of power. Relay 1 functions as the low alarm relay, and will activate after the alarm delay for low pressure, low flow, low temperature and low RH alarms.

  • Page 15: Technical Section

    Part Two Technical Section The PresSura™ Room Pressure Controller is ready to use after being properly installed and configured. The TSI through-the-wall sensor is factory calibrated, as are most pressure transducers. Figure 4 shows the Digital Interface Module (DIM) which is programmed with a default configuration that can be easily modified to fit your application.

  • Page 16: Software Programming

    Software Programming Programming the PresSura Model RPC30 controller is quick and easy if the proper keystroke procedure is followed. The programming keys are defined first, followed by the required keystroke procedure. At the end of this section is a programming example. NOTE: It is important to note that the unit is always operating when programming.

    Pressure Sensor Cleaning Accumulations of dust or dirt can be removed with a dry soft-bristled brush (such as an artist's brush). If necessary, water, alcohol, acetone, or trichlorethane may be used as a solvent to remove other contaminants. Use extreme care when cleaning the velocity sensors. The ceramic sensor may break if excessive pressure is applied, if sensor is scraped to remove contaminants, or if the cleaning apparatus abruptly impacts the sensor.
