Page 8: Introduction
The HMS-2000 provides maximum fume hood status awareness with color coded visual alarms both on screen and with the 360° Safety Halo illuminated edge. When the 360° Safety Halo is enabled, staff can easily monitor fume hoods in large laboratory spaces. - Page 9 HMS-2000 Figure 2: Alarm screen Figure 3: Standby mode Figure 4: Emergency Purge mode Figure 5: Normal occupied LIT-12014488...

Page 12: Initial Setup
Initial setup When the HMS-2000 Fume Hood Controller starts for the first time, you can configure the device language, units of measurement, network address, and any required calibration procedures. See Table 4 for definitions of occupied, unoccupied, and standby operating modes. -
Page 13: User Accounts
User accounts Setting up users and passwords restricts the use of the HMS-2000 Fume Hood Controller to specific groups of people. This is not mandatory, but if you do not create users and passwords, anyone can access all functions of the HMS-2000 controller. The following access levels are available: •... -
Page 14: Creating A Restricted User And Pin
If admin users forget their password, they have to complete the following procedure: Contact support and provide them with the device identifier listed on the screen of each HMS-2000 Fume Hood Controller. See Contact information at the end of the User’s Guide for more details. -
Page 15: Network Setup
The device ID (or instance number) is a number used to identify a BACnet device object. Each BACnet device on a site must have a unique device ID. The HMS-2000 creates a default device ID of 85,000 plus the current MAC address. For example, if the MAC address is 25, the default device identifier becomes 85,025. -

Page 19: Analog I/O
Admin users can set up analog inputs (AI) AI-1 to AI-4, analog outputs (AO) AO-1 to AO-4, and map analog inputs to any of the four analog outputs. See Table 11 for more information about which parameter can be configured to which analog input. Refer to the HMS-2000 Fume Hood Controller Installation Guide for more information. -
Page 20: Configuring Analog Inputs To Measure Pressure
Configuring analog inputs to measure pressure To configure the HMS-2000 controller for pressure, you can use AI-2, AI-3 and AI-4. Analog Input 1 is only configured for monitoring face velocity and is pre-configured by the factory. If you are using a third-party pressure sensor you need to select pressure from the list of input types. -
Page 21: Specifying The K-Factor
HMS-2000 Specifying the K-Factor The default value for the K-Factor is 1.0, but the manufacturer of the sensor can provide a different K-Factor to serve as a correction factor for the actual output of the sensor. If you do not receive a different K-Factor from the manufacturer, leave the K-Factor at its default value. -
Page 22: Zero Calibration
Setting the alarms The HMS-2000 Fume Hood Controller supports alarming across all four analog inputs, including the face velocity input. You can disable the alarms for AI-2, AI-3, and AI-4 if required. For users’ safety, you cannot disable the alarms for the face velocity input. -
Page 23: Configuring The Analog Input To Measure Air Flow
HMS-2000 Configuring the analog input to measure air flow You can display room cfm in AI-2, AI-3 and AI-4 with either a DP transmitter or a flow sensor. Configuring the analog input to measure air flow On the home screen, tap the CONFIG icon to enter the CONFIGURATION menu. -
Page 24: Setting Up The Duct Area To Measure Air Flow
HMS-2000 Setting up the duct area to measure air flow If you are using a DP transmitter, specify the cross-sectional duct area in square inches. This duct area converts a differential pressure or a velocity to a real-time volumetric flow. For round ducts, the cross-sectional area is determined by multiplying the square of the radius by pi. -
Page 25: Enabling The Alarm And Changing The Alarm Limits For Air Flow
Naming the air flow input Set up a name for the analog that input you want to appear on the home screen. If your HMS-2000 controller is in portrait mode, you can have up to 16 characters. If your HMS-2000 controller is in landscape mode, you can have up to 12 characters. -
Page 26: Configuring Digital Inputs For Flow Switch Mode
HMS-2000 Configuring digital inputs for flow switch mode Configure one of the secondary digital inputs for flow switch mode. In this mode an external signal from a flow switch can trigger the alarm to indicate insufficient air flow in the exhaust duct. -
Page 27: Configuring The High And Low Setpoints
Configuring the high and low setpoints When using the setpoint trigger mode, the HMS-2000 controller has to be in either occupied or unoccupied mode to enter the high and low relay setpoints. If the system is in standby operating mode, then setpoint entry is not available. The high setpoint determines the threshold that the relay is activated if in direct acting mode, or gets deactivated if in reverse acting mode. -
Page 28: Configuring The Pid Loop
HMS-2000 Configuring the PID Loop If you configure any of the analog outputs in PID mode, you can use the PID Loop Setup menu to fine-tune the PID constants that the closed-loop control scheme uses. See Table 14 for information on default values. -
