1.0 FEATURES

The SRIMV is a multi-mode (air velocity, flow, pressure, temperature and humidity) monitor. It has a 3 color backlight display, a digital input for a door switch, 2 analog inputs for temperature and humidity, 1 relay output for remote alarm indicat ion and an internal pressure sensor. It can display and alarm on Velocity, Flow, Pressure, Temperature and Humidity parameters.

User Interface

• Large LCD 2 line display shows values of the monitored parameters

• Green (Normal), Yellow (Warning), Red (Alarm) Backlit display for indicating the status

• Membrane keypad for ease of configuration and me n u navi g a tio n

• Password Protection for security

Audible Visual and Remote Alarms

• Color Backlight LEDs

• Alarm on Pressure, Velocity, Flow, Temperature and Humidity

• Audible Buzzer

• Alarm delay, mute timeout, alarm enable/disable, buzzer enable/disable

• SPDT Relay for remote alarms, including Setra Remote Annunciator (SRAN)

Ease of Installation and Calibra tion

• Flush mount (mounts flush to wall surface) and duct mount (surface mo unt) versions; both are

wipe-down compatible for decontamination

• Rotate-able pressure fittings to eliminate crimping of pressures hoses, allows installation

flexibility

• Snap on cover, no visible fasteners

• Modular plug-in design usi ng sub-base. Simultaneous electrical and plumbing connections

reduce initial installation and ca libration costs. Unit can be calibrated in house or sent for calibration service without removing the wiring or plumbing

• Push button zero and span calibration, no potentiometer adjustments

• PG9 and Conduit fitting in same unit, field sele c ta ble

Versatile

• Field selectable outputs, 4-20 mA, 0-5 VDC or 0-10 VDC

• One unit that can be field configurable for almost all duct and room measurement applications

2.0 SRIMV Included Parts

Fig. 2-1 Parts Provided

The SRIMV parts list includes:

• SRIMV Velocity Monitor

• Accessories: ordered separately

For Velocity and Flow measurement a Pitot tube, averaging pro be or flow station is required as an input to the pressure ports on the SRIMV. Setra offers the following averaging probe. Averaging Flow sensor: P art # 242915-xx

The SRIMV can be used with any manufacturer’s probe. The “k” factor flow coefficient must be entered into the SRIMV at commissioning. The d e fault setti ng a s shipped is K=1. K factor changes based on probe length.

Installation

The 242915-xx units utilizes 1/4  ID, 3/8  OD tubing. First check that there are no sharp bends in the tubing at any connection. Connect the “H” Po r t to the high input on the SRIMV units. Connect the “L” Port to the low input on unit.

Approximate K factors for models:

242915-01: 1.32 242915-02: 1.39 242915-03: 1.46 242915-04: 1.46 242915-05: 1.58 242915-06: 1.67

Mounting

1. Install the unit horizontally to ensure accurate readings for units ranging fro m 3-5/32  to 9-29/32 . If using a unit longer than the 242915-05, which is 9- 29/32 , vertical mounting is recommended.

2. Determine the duct’s flow direction and install the model 2429150-xx based on the unit’s flow arrow imprint.

3. Cut a 7/8  hole in the ducting to accept the unit; tip should be at least to the center of duct.

4. Attach using two se l f-tapping screws inserted in the 3/16  mounting hoes.

3.0 Installation

The SRIMV is available in two models suitable for wall (flush mount) and surface mounting (panel mounting). The front panel of the product and the rear housing are snapped together. The two snaps are located on the left and right sides of the front pa nel. A 1.5mm（1/16 inch）Allen wrench or paper clip can be used to open the concealed snap fastening system. The rear housing can be used to mount to a wall or into a 3 gang “off the shelf” electrical box. Conduit (1/2”) or a PG9 cable connection are available for wiring to the terminals at the rear of the unit. The rear housing acts much like a thermostat sub-base that does not have to be removed once installed. The front bezel contains the pressure sensor, PCBA and display. It is a complete module that can be calibrated. The pressure and electrical connectors are disconnected simultaneously when the front bezel is removed.

Before installing, determine a good installation locatio n. For flush mount applications, the corridor outside the room is preferred. For surface mount applications the unit may be mounted on the duct work (avoid high vibration), a stable surface near the ductwork or inside a panel.

Unpack the product box. Do not remove the protective fil m on the front display screen until after installation to prevent scratching of the display during the installation process. Remove parts and place them on flat surface. Apply pressure on the side of the box to open the snap fit or use an Allen wrench or paper clip as shown See Figure 1-2. First one side then the other, then pull the bezel forward to remove it from the housing.

Plumbing and Wiring to the Electrical Box (Rough in)

Flush mounting:

Use a 3 gang electrical box RACO 697 or equivalent or mount directly into the wall. If mounting directly into the wall create an opening approximately 2.8” (71 mm) by 5.4” (134 mm). If using t he 3 gang bo x use #6 machine screws to mount the ears o f the SRIM rear housing to the electrical box. If mounting directly into the wall without an electrical box, use drywall screws to mount the 4 ears of the SRIMV box to the wall.

Display Parameters

Unit in the normal state, line 1 indicates differential pressure, velocity or flow and the corresponding engineering units. Line 2 indicates the temperature and humidity reading, if enabled. The green backlight indicates that the velocity (or pressure or flow), the temperature and humidity is within the allowable alarm limits. Note that the alarm will occur if any of the 3 monitored parameters are outside of their respective limits.

Unit shown in alarm state. There will be a red backlight with an arrow indicating which parameter is in alarm and if it is above or below alarm limits. The audible buzzer will also be active if it has been enabled.

Menu Operation

Menu key – Provides access to the menu structure

Down arrow key – Allows selection of numerical parameters. Pushing the down arrow causes the digits to move upwar ds in a 1 digit count and will wrap around. The cursor below the indicated item in the current men u item indicates that this is the digit that is being change d. If you don’t need to make a change to that position press the enter key to move to the next position to the right.

Enter key – Use this key to move left to right in a current menu screen. It is also used to save the current men u items selected settings, or to confirm the curr e nt menu operation. Press the Enter key to save the current settings; the display will show the current setting value and flash twice, and prompt the user that the value currentl y set has been saved. Ther e is no “back” button, so if the user proceeds past the desire parameter they must go back to the start of that menu screen.

Return/Silence button – This button provides a quick way to return to the home screen from anywhere within the menu structure. It h as the secondary pur pose of temporari ly silencing the audible alarm. If the mute timeout setting is reached the audible alarm will again sound.
