VMS-1655M
Vortex Monitoring System
Installation Guide
Overview
Use the VMS-1655M Vortex Monitor in the Flowsafe Stable Vortex II fume hood and Flowsafe Stable Vortex conversion kit to measure
and control the vortex pressure and adjust to maintain correct fume hood containment. The VMS-1655M adjusts for environmental
and usage conditions such as sash movement, fume hood loading, room pressure fluctuations, and cross drafts with active vortex
stabilization in real-time. The alarm function notifies you if there is a compromise in fume hood performance. Some of the features and
benefits include:
•
Full-color touchscreen display with programmable display options and adjustable back-light
•
360° Safety Halo
™
•
Intuitive user interface that simplifies setup and configuration of unit
•
Optional display mode to show real-time face velocity at main screen
•
Graphical hood status display
•
Audible and visual alarms
•
Multi-level password protection
•
1 analog input: 0 VDC to 10 VDC
•
2 analog outputs, actuator control, exhaust air flow feedback
•
BACnet® MS/TP network comms
•
Real-time view facility facilitates diagnostics during setup and commissioning
IMPORTANT: Make all wiring connections in accordance with the National Electrical Code and local regulations. Use proper
Electrostatic Discharge (ESD) precautions during installation and servicing to avoid damaging the electronic circuits of the VMS-
1655M Fume Hood Monitor.
IMPORTANT : Assurez-vous que tous les branchements de câbles sont effectués selon le Code national de l'électricité et les
réglementations locales. Utilisez une bonne protection contre les décharges électrostatiques (ESD) pendant l'installation et l'entretien
pour éviter d'endommager les circuits électroniques du VMS-1655M Fume Hood Monitor.

Page 17: Vms Configuration
VMS-1655M VMS configuration The VMS configuration tool comes as a zipped file folder. To connect the tool to the sensor, you need a USB to RS485 cable, available from an online retailer or from the JCI factory. To install the VMS configuration tool, complete the following steps on a laptop: 1. - Page 18 VMS-1655M Figure 19: Comm port number Make sure that the VMS sensor powers on. The USB plug flashes red for the request and green as a response from the sensor. Some of the pressure and face velocity fields populate. The GET buttons request and present the associated information. Get Serial, Get Date, and Get FW Rev return preset information about the sensor unit.
- Page 19 VMS-1655M 4. Remove the cap from the sensor. 5. Adjust the hood sash so that the face velocity is at a normal operating value or higher than 60 fpm. Wait until the value stabilizes. 6. Use an external velocity measuring instrument, for example, Shortridge, Alnor or equivalent, to measure the velocity at the face.
- Page 20 VMS-1655M Calibrating the characterization table The Flow Safe fume hood uses a vortex technology to maintain fume hood safety. A baffle at the rear of the fume hood manipulates the vortex. The face velocity derives a characterization table that determines the position of the baffle. As each fume hood is different, and the cfm settings are different, the characterization table may need calibration in the field with its respective hood.
- Page 21 VMS-1655M The table in the tool updates with values that correspond to the high and low face velocities, as well as the max face velocity. Figure 27: Updated Hood Charactization table Optional flow sensor setup The controller can accept three input signal ranges (0 V to 5 V, 0 V to 10 V, 4 mA to 20 mA) from a pressure or flow sensor that attaches to a flow probe in the duct work.
- Page 22 VMS-1655M To calculate and generate the cfm and cfm 4 mA to 20 mA, the tool uses the following parameters: • Pressure reading: The pressure sensor calibration, gain, and offset. • K factor • Valve area • Scaling factor for cfm to 4 mA to 20 mA conversion...
