The Triatek HMS-1650 Series Fume Hood Controller is an ultra-sensitive
instrument used to monitor and/or control the fume hood face velocity in
laboratories and clean rooms. This unit is a precision measuring system
capable of measuring and displaying face velocities from zero to 200 ft/
min (1.016 m/sec) with an accuracy of ±2 ft/min.
Key features of the HMS-1650 include:
• Comprehensive closed-loop sash control with sidewall velocity
sensing
• Full-color touchscreen display with programmable display options and
adjustable backlight
• Intuitive user interface simplifies setup and configuration of unit
• Display background changes color to indicate hood status at a glance
• Audible and visual alarm annunciation
• Auxiliary universal analog inputs for use with optional sensors
• Four independent PID control loops for controlling damper actuators,
speed drives, hot water valves, humidifiers, etc.
• Digital input used to monitor an optional fume hood sash switch, zone
presence sensor, or emergency override switch
• Relay outputs used for transmitting alarm condition to remote location
• Dedicated thermistor inputs for temperature monitoring and/or control
applications
• Multi-level password protection of touchscreen user interface
• Field Calibration of both sidewall velocity sensor and optional sash
position sensor
• Multi-protocol native (BACnet®, Metasys® N2) for easy integration
with any BMS
• Manual override of Analog and Relay outputs assist with Test &
Balance procedures
• Comprehensive Real-Time View diagnostics tool displays built-in to
each unit
• Easy-to-install backplane/backplate assembly facilitates permanent
termination of all wiring
The HMS-1650 is equipped with a 3.2” diagonal
Full-color
Touchscreen
display in portrait orientation (240 x 320). The password-
protected menu tree is very intuitive and simplifies the setup and
configuration of the unit. The menus incorporate touch-based interfaces
such as sliders, radio buttons, and dialog popups to facilitate the ease-
of-use of the HMS-1650.
The display implements bright background color changes to indicate the
three different
Alarm Status
indications of the monitored fume hood.
These background colors indicate “Normal” when the face velocity is
within defined limits, “Warning” when the face velocity is nearing an out-
of-limits condition, and “Alarm” when the face velocity is outside defined
acceptable limits. The face velocity ranges for these conditions are
easily set by the user for the specific installation when necessary. The
background color changes provide an overview of the monitored fume
hood face velocity conditions at a glance.
Alarm conditions
may be defined by the user, in terms of desired face
velocity settings for the fume hood being monitored. When an alarm
condition occurs, it may be annunciated in four user-definable ways: 1)
on the display, 2) with an audible alarm, and 3) transmitted via contacts
to a remote monitoring location and 4) over the BMS network. The alarm
will automatically reset when the unit has sensed that the fume hood
face velocity has returned to proper limits. The operator may easily mute
the audible alarm by touching the OK button on the alarm notification
message popup window of the touchscreen display.
For many applications, it is important to have other variables such as
sash position or ambient temperature displayed along with the fume
hood face velocity. The HMS-1650 provides for this by means of three
additional
Universal Analog Inputs
, each of which may be configured
for either current loop operation or voltage input operation (0-5V, 1-5V,
0-10V, 2-10V, 0-20mA, 4-20mA). Each input may be scaled as needed
to display correct values, and may have an engineering units selection
associated. The configuration of each analog input is field selectable
through the use of miniature dipswitches on the controller unit.
For those applications requiring monitoring and/or control based
on temperature variances, the HMS-1650 provide two dedicated
Thermistor Inputs
in addition to the four universal analog inputs.
Therefore, a total of six analog inputs are available for control
applications. The two thermistor inputs may be used with negative
temperature coefficient (NTC) Type 2 or Type 3 sensors.
The HMS-1650 provides four
Universal Analog Outputs
, which may
be configured for either current loop operation or for voltage operation.
Each analog output may be configured for proportional operation to
provide a linear signal to the BMS, or for PID (proportional-integral-
derivative) control operation for closed-loop feedback control of
damper actuators, variable frequency (speed) drives, hot water valves,
humidifiers, or other analog-controlled devices. Each universal analog
output may be field-configured for the required application using onboard
configuration dipswitches on the controller module. Each analog output
