Quick Start Guide Introduction
Following the proper installation of the HMS-1655L, apply power to
the unit. Upon power up, the Safety Halo™ status indication bezel
will cycle through seven colors (red, green, blue, yellow, magenta,
cyan, and white), and then the Triatek splash screen indicating serial
numbers, firmware version numbers, Neuron ID, Program ID, and
current network address will be displayed. The splash screen remains
displayed for approximately 10 seconds, and then disappears to reveal
the main display screen.
NOTE:
The information displayed on the splash screen during the
power up sequence may also be redisplayed using the
About This
HMS
option on the
Diagnostics
menu.
Main Display Screen
All HMS-1655L units are shipped from the factory in the
Standby
operating mode, which is represented by a blue screen with a slashed
circle icon at the center of the screen as shown in Figure 2. The
information that is displayed on the main screen includes the following
from top to bottom:(see Figure 2):
•
Fume hood name in the upper window (up to 25 characters)
•
Current face velocity (default units: ft/min)
•
Current operating mode and status
•
Intuitive status icon centrally located
•
Current sash height in the lower window (default units: inches)
Located below the main screen are is audible toggle button and the
emergency purge button, if it has been enabled. The emergency purge
button may be used to instantaneously force the exhaust damper to the
maximum open position in the event of a chemical spill or other unsafe
condition at the fume hood work space.
While in standby operating mode, the graphical background is blue
in color. However, while in either
Occupied
or
Unoccupied
mode, the
graphical background intuitively represents the current alarm status of
the unit. A green graphical background with a check mark at the center
indicates that the current face velocity is within allowable limits of the
desired setpoint.
A yellow graphical background with an exclamation point at the center
indicates that the current face velocity has drifted outside the allowable
limits of the desired setpoint and is in the caution range. A red
graphical background with an exclamation point at the center indicates
that the current face velocity has reached a critical unsafe condition,
as it is beyond the safe operating range. An alarm buzzer will sound at
this screen as well providing an audible alert of the unsafe conditions.
The HMS-1655L incorporates a full-color touch screen with an
extensive easy-to-use menu system that allows the user to quickly
setup the controller for immediate use. Also integrated into the
HMS-1655L display are several hotspots that provide quick access to
various settings. Refer to page 31 for details on using these hotspots
as display settings shortcuts. Touching the screen anywhere other than
one of the reserved hotspots invokes the menu system, unless one or
more security passwords have been entered.
Configuring Fume Hood Controller
Configuring the HMS-1655L fume hood controller settings can be
accomplished in four simple steps:
1.
Calibrate the sidewall sensor
2.
Calibrate the sash position sensor
3.
Configure the analog output
4.
Configure alarm limits
The HMS-1655L incorporates a closed-loop control scheme which uses
a flow sensor mounted in the sidewall of the fume hood to maintain
