Quickstart Guide

1.Intended Use

Thank you for purchasing the Setra FLEX, the industry’s most advanced and flexible room environmental monitor.

Setra FLEX is designed for indoor use only to monitor critical environments by providing differential pressure indication and additional

parameters such as temperature, relative humidity, air changes per hour, and user-dened information. Typically this is between a monitored

room and a reference space such as a corridor or ante room. The unit also provides monitoring, control, alarm, and communications

functions.

Typical Applications:

1. Hospitals – patient isolation and protection rooms, operating suites, intensive care and emergency rooms.

2. Pharmaceutical, semiconductor, precision manufacturing and clean rooms

3. Laboratories – medical research, BSL (bio safety labs), radiation, vivarium, toxic metals and chemicals.

4. Installation

• Make the nal connections by pushing the removable

connectors and wires into the back of the FLEX unit. If

connecting BACnet/IP, insert the RJ-45 cable into the Ethernet

port. If connecting pressure tubing, align HIGH and LOW ports

to their appropriate pressure sensor connections with anti-

kink tubing and secure in place.

• Slide the FLEX unit back into the wall, taking care to not crimp

tubing or damage wires.

• Secure the FLEX base unit into the electrical box with the four

(4) mounting screws provided. Allow the FLEX display to hang

below the mounting box, taking care so that the display does

not get damaged by tools.

• BACnet MS/TP hardware is implemented as isolated RS485.

Wire to Connector COMM, labeled BACNET. Connect TX line

to B (+), RX to A (-) and ground wires to GND. Connect shields

together with wire nut. Hardware conguration is done using a

three position dip switch located in the upper center section of

the rear PCB. Use a small flat blade screwdriver or pen to push

the switch to the right to turn the function on, or to the left to

turn the function off. If the unit will be at the end of the line,

the terminating resistor can be enabled by pushing position

1 to on.

• With the FLEX display hanging open and unit powered, re-zero

the sensor to ensure accurate operation:

1. Remove one end of each pressure tube (shown here)

2. Access “Settings” > “Maintenance” > “Pressure Calibration”

3. With tubes disconnected, press “Adjust Zero”

4. Reconnect tubes

• The unit is now ready for nal mounting

• If live power is already turning on FLEX, power can be cycled on

FLEX by removing the J6 jumper on the unit. This can be done

by hand, or carefully with non-conductive pliers. Normally,

FLEX is continuously powered and this jumper does not need

to be accessed.

• Swivel up the FLEX display, and push rmly at the frame just

above and just below the touch screen. The display will snap

into place and seal against the wall surface.

5. Power Up Conguration

• Access the “cog wheel” on the top-right of the FLEX display to

congure the unit.

Phone: [phone] | Fax: [phone] | www.setra.com

• Use “Device Conguration” for initial setup.

• The next seven menus (three tiles over four) permit complete

conguration of your FLEX unit. Detailed instructions for each

menu can be found in the FLEX Installation & Operations Guide.

8. Maintenance

• The FLEX is designed to operate in an indoor environment, monitoring clean, dry air.

• Upon nal installation of the FLEX Environmental Monitor, no routine maintenance is required. An annual check of system calibration is

recommended. FLEX is not eld serviceable and should be returned if repair is needed (eld repair should not be attempted and may void

warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive

a return goods authorization number before shipping.

• WARNING: Do not blow into the pressure tubing or ttings with mouth, compressed air, or canned air. Such actions may permanently

damage the pressure sensor. Do not clean or wash-down FLEX with industrial cleaners or solvents other than those approved in

specications. Do not immerse unit.
