Introduction

The Setra Lite provides a simple, cost-effective, and accurate way to measure and display
room differential pressure in areas that previously require manual verification. For local staff managing area, Setra Lite visual and audible alarms. The light ring displays green or red, showing a clear indication of room conditions. For the facility manager, using the Lite means the frequency of preventative maintenance walk-by inspections can be reduced because Setra Lite is monitoring the space. Setra Lite has many features found only in larger, more complex room pressure monitors.

These include a bright light ring that can be seen at an angle or down a hallway, a digital
display of the pressure value that is always-on or momentary, an alarm delay for door entry, and POS or NEG room mode. The Setra Lite sensor has Setra’s accuracy and reliability that you can trust.

Setra Lite is about the size of a standard light switch and just as simple to install. It fits in a single-gang US electrical box, international 86-box or international round back-box, and is powered by 24VAC or 24VDC. Additional mounting options are available for temporary spaces or replacement of existing pressure monitors. The reference side pressure pickup is integral with the Lite faceplate. An analog output provides the building management system with the pressure signal for any additional trending or alarming needed.

The Setra Lite also integrates seamlessly with the Setra Flex environmental monitor. Mount Setra Lite at additional doors that enter the space and use an on-screen badge to display its value.

Intended use

Setra Lite is designed to sense and indicate the pressurization status of critical environments, including cleanrooms and sensitive hospital areas (sterile bronchoscopy rooms, and other USP 800 compliant pressurized spaces). Setra Lite is designed to provide an intuitive visual and/or audible indication of the status of the room and can also be tied into other devices via analog output.

Display and LED light ring

Setra Lite features an LED light ring that will glow red and/or audibly alarm if room pressurization exceeds the configured alarm threshold. With a simple press of the front lens of the unit, the LCD displays the current differential pressure and silences the audible alarm. Configuration of the unit can be performed on the device via buttons located behind the removable front lens. The unit can be put into and taken out of “Standby” mode by pressing the front lens 3 times in quick succession.

Rough-in installation (Wall Mount)

For Setra Lite to be installed correctly, the rough-in phase of the project must be completed properly. This section will outline the specific considerations the Installer must pay attention to so that the final wiring and commissioning will go smoothly

Installer Provided Materials

The following is a list of parts required and supplied by installer for Setra Lite:’

1. Power (18-22 AWG recommended) and signal wire
2. 1/8 in. ID silicon tubing to run from the room(s) Pressure Pickup Port(s) to the Setra Lite monitor or external sensors. (Standard monitor only)
3. 24 VAC or VDC transformer, capacity rated for number of Setra Lite units powered
4. Single-gang electrical box, if opting not to install directly into wall
5. Single-gang electrical box, one per Pressure Pickup Port, if opting not to install directly into wall

Prepare wall for mounting – Permanent installations

1. Cut a 2″ hole in the wall for the Setra Lite base unit or install 1-gang electrical box
   Note: Be sure to install electrical box in correct orientation based on purchased configuration (Portrait or Horizontal)

2. Cut a 1″ to 2″ hole or install 1-gang electrical box for each Pressure Pickup Port (RPS), either horizontal ceiling mounted or vertically mounted high on a wall surface Standard: Install RPS either horizontal ceiling mounting or vertical mounted high on a wall surface Dual Alert: Cut a 2″ hole in the wall. Install pressure pickup port on opposite side of the wall from base unit in portrait or landscape orientation based on purchase configuration

3. Run all wiring to the Setra Lite electrical box

Plumbing

For the standard Lite , a Pressure Pickup Port (RPS) is installed in the primary monitored room and Setra Lite is installed in the reference area (typically a hallway). For the Inside Room Lite (“IR” on the startup screen under the Setra logo), the Pressure Pickup Port (RPS) should be installed in the reference area and the Setra Lite is installed inside the primary monitored room. 1/8” ID soft platinum-cured silicon tubing is typically used to bring the pressure signal from the Pressure Pickup Port to the pressure fitting on the back of Setra Lite.

Note: Caution should be taken to locate the Pressure Pickup Port and Setra Lite at least six (6) feet from air turbulence that may originate from air supply diffusers, slot diffusers, mobile equipment cooling fans, or other devices that may exhaust air in the direction of the ports. Air velocity blowing directly on these ports can cause inaccurate pressure measurement

Considerations to avoid kinked or damaged tubing

Pull tubing runs in a manner that protects the tubing from being damaged, cut, or crimped. Any break or bend in the tubing may affect the integrity of the pressure signal. DO NOT TIGHTEN STRAIN RELIEFS at the electrical boxes so that they crimp the tubing. Leave the strain reliefs open enough so that the tubing can slide in and out of the box with a few inches of play. During tubing installation and prior to use, tape the open ends of the tubes closed to prevent contamination during construction.

During final installation of the Pressure Pickup Port, careful observation should be made of how the tubing gets pushed back into the wall for final faceplate mounting.

Installing Lite base unit (Permanent installations)

1. Connect pressure tubing from the Pressure Pickup Port to the port on the back of Setra Lite.
   

2. Connect wiring for power and analog output (if required) per section 7.0 Dual Alert: This variant will have an additional wire lead connected to the back of the unit. Thread the wire lead through the wall and into the pressure pickup port box or hole on the opposite side of the wall.
   

3. As you push the Setra Lite unit into the electrical box, push the tubing into the conduit tube or into the wall cavity
   

4. Push Setra Lite into the enclosure and secure with two (2) mounting screws.
   

5. When the home screen appears, Setra Lite can be configured via 3 buttons located below the LCD display on the circuit board. See section 8.0 for configuration instructions and details.
   Note: Setra Lite should be installed, powered and operational for 30 minutes for warmup and acclimation for one-time pressure sensing stabilization. If necessary, after the warmup, units can be re-zeroed. Setra Lite contains a small air valve to allow for one touch zeroing via the configuration menu.

6. Prior to installing the faceplate, be sure the rubber seal is properly installed on the back of the faceplate.

7. Install the faceplate by firmly pressing it into place over the base unit housing. **Note: Press the plate in at a slight angle, leading with the bottom edge.
