Building Management Systems
Often we have to interface with
 BMS Building Management
 Systems.

Here is a primer of the terms and
 technology used in this business.
Building Management Systems
   BMS “Language”
    • Points:
    • AI Analog Input
    • AO Analog Output
    • BI or DI Binary / Digital Input
    • BO or DO Binary / Digital Output
Building Management Systems
 Analog Input can be variable
  voltage, current, or resistance
  signal.
 Analog Output can be variable

  voltage or current.
Building Management Systems
 Binary or Digital I or O think
  “dry contact”.
 Dimming ballast on a BMS

  required 2 points for output:
    • 1 BI for switching the power on /
      off
    • 1 AO to provide the 1-10 volts.
Building Management Systems
 These are generated by a circuit
  on the serial signal “node” or
  “gateway”.
 Manufacturer specific hardware

  and software in a control system,
  to access BMS addressing and
  address to control properties of
  each node.

Dimmer and Load Types
   Characteristics of Load determines
    technical capability of dimmer
   Incandescent: Resistive, simple loads.
    Construction can enhance noise
    transmission or suppression. Tungsten
    Halogen types of Incandescent are
    generally less noisy. They require a period
    of high temperature operation to maintain
    the tungsten cycle.
Dimmer and Load Types
   Magnetic Low Voltage- Generally sees load
    connected to transformer, almost complete
    dimming range. DC a danger.
   Neon Very similar to Magnetic LV, often
    with low end cutoff
   Electronic LV- Very Different, often called
    “Capacitive load”. Needs firm zero crossing
    (Start of dimming cycle) for power
    converter synchronization.
Dimmer and Load Types
Fluorescent -electronic dimming ballasts, 2
  or 3 wire control “line voltage phase
  control”. Or 4 wire 2 wires for switched
  power and 2 for 0-10 volt control signal.
 Emergency in General Must turn on load
  despite dimmer setting. Easy with
  incandescent & LV loads. Much harder
  with fluorescent loads. Prefer 2 wire
  control schemes for this purpose.
Fluorescent Dimmers
   3 Control Techniques
                         2 wire Phase Control and Neutral to 1 or more
                                  Dimming Ballast
                                  Tuwire & Mark 10 Known Brands

                         3 wire Phase Control Switched Power and Neutral
                                 to 1 or more Dimming Ballast

                         4 wire Switched power and Neutral with
                                  additional 2 low voltage 0-10 volt wired to
                                  1 or More Dimming Ballasts
                                  Helios, Mark 7, Known Brands

    NOT INTERCHANGABLE WITH SPECIFIC APPLICATIONS
Dimmer Technology
    (Forward) Phase Control, Triac, Dual SCRs
 “Reverse Phase Control” Dimmers
  Semiconductor must be able to turn off.
FET, IGBT semiconductors
 Sine-wave Dimmers Semiconductors to

  turn on and turn off circuit and to shape
  the dimmer output to track the shape of
  the wave of the incoming power.
High Density Dimming Systems
Rack Consideration
 Fault Current Rating
 Size and Mounting
 Cooling
    – Fans with Noise
    – Convection – may require cooler ambient
      temp
Dimmer Specifications - Racks
 DMX Isolation:
 All DMX512 & RS485 communication ports and remote contact input
  connections shall be optically isolated from all processor electronics
  by a minimum of 2,500V RMS isolation.

 Life Safety Code Panic: (Also bridge to Building Fire Alarm
  System)
 The Rack Processor Housing shall have the provision to select any
  of a maximum of 192 dimmer outputs to be activated by the PANIC
  function. The PANIC function shall be activated or de-activated by
  one or more local or remote contact closures.

 Dimmer and Processor Speed:
 The dimmer control electronics shall have 16 bit (minimum) fade
  processing and a dimmer update rate better than 16 ms
Dimmer Specifications - Racks
 Line Regulation:
The dimmer output levels shall be regulated for
  incoming line voltage variations. The regulation
  shall adjust for both RMS voltage and frequency
  changes of the incoming AC wave form.
  Regulation shall maintain the desired output
  voltage +/- .5V volt for the entire operation
  range (90 – 264 VAC). The regulation shall
  compensate for variations of the AC waveform
  on a dimmer-by-dimmer basis.
Dimmer Specifications - Racks
 Output Filtering:
Basic Rise dimmers shall have a rise time of not
  less than 350 microseconds A measured at 90
  degrees conduction angle B from 10% to 90%
  of output wave form C with dimmer operating at
  maximum load D. Voltage rate of rise (slew rate)
  must not exceed 420 millivolts per microsecond
  in any point of the wave under full load
  conditions
Dimmer Specifications - Racks
 Output Filtering:
 2.5.3 Medium rise time dimmers shall
  have a rise time of not less than 500
  microseconds
 2.5.4 Hi-Rise dimmers shall have a rise
  time of not less than 800 microseconds
Filtering Criteria
   A: Rise time- in microseconds, 350 minimum 800
    premium
   B: Conduction Angle- 90 degree worst case
   C: Percentage of waveform 10%-90%
    conventional, 10%-95% or others is improving
    spec by increasing amount if waveform
    measured.
   D: Load: Theatrical manufacturers measure at
    full load, (rarely achieved), other amounts as
    stated.
   E.: Slew Rate, some filters can take adequate
    overall time, but take too long to respond, for
    example, and result in noisy lamps.
Dimmer Specifications - Racks
 SINEWAVE Dimmers:
Dimmer output waveform shall be a fully
  symmetrical Sinewave at any output
  voltage setting eliminating all lamp noise
  and reducing reflected harmonics on the
  building power supply. Total Harmonic
  distortion shall be less than 1% and
  efficiency shall be 98%.
Dimmer Specifications - WBD
   SPEC From website information
    – DIMMERS
        Manufacturer:
        Electrical Specifications
           – Input: 120 VAC @ 60Hz, 277VAC @ 60Hz OK
           – Line Voltage Regulation
           Where is specification???? These can have line regulation, but
             what is it?
           – RFI Noise Suppression
           Sure, but what??? WBD have been measured (by me) at 110 ms,
             10-90% 90 degrees, full load. So “De-buzzing” coils (additional
             chokes) are sold for sensitive situations and loads.
        Maximum Load: 120V incandescent: 1500W stand-alone, OK

    Building Management Systems Oftenwe have to interface with BMS Building Management Systems. Here is a primer of the terms and technology used in this business.
  • 35.
    Building Management Systems  BMS “Language” • Points: • AI Analog Input • AO Analog Output • BI or DI Binary / Digital Input • BO or DO Binary / Digital Output
  • 36.
    Building Management Systems Analog Input can be variable voltage, current, or resistance signal.  Analog Output can be variable voltage or current.
  • 37.
    Building Management Systems Binary or Digital I or O think “dry contact”.  Dimming ballast on a BMS required 2 points for output: • 1 BI for switching the power on / off • 1 AO to provide the 1-10 volts.
  • 38.
    Building Management Systems These are generated by a circuit on the serial signal “node” or “gateway”.  Manufacturer specific hardware and software in a control system, to access BMS addressing and address to control properties of each node.

    Dimmer and LoadTypes  Characteristics of Load determines technical capability of dimmer  Incandescent: Resistive, simple loads. Construction can enhance noise transmission or suppression. Tungsten Halogen types of Incandescent are generally less noisy. They require a period of high temperature operation to maintain the tungsten cycle.
  • 51.
    Dimmer and LoadTypes  Magnetic Low Voltage- Generally sees load connected to transformer, almost complete dimming range. DC a danger.  Neon Very similar to Magnetic LV, often with low end cutoff  Electronic LV- Very Different, often called “Capacitive load”. Needs firm zero crossing (Start of dimming cycle) for power converter synchronization.
  • 52.
    Dimmer and LoadTypes Fluorescent -electronic dimming ballasts, 2 or 3 wire control “line voltage phase control”. Or 4 wire 2 wires for switched power and 2 for 0-10 volt control signal.  Emergency in General Must turn on load despite dimmer setting. Easy with incandescent & LV loads. Much harder with fluorescent loads. Prefer 2 wire control schemes for this purpose.

    Dimmer Technology (Forward) Phase Control, Triac, Dual SCRs  “Reverse Phase Control” Dimmers Semiconductor must be able to turn off. FET, IGBT semiconductors  Sine-wave Dimmers Semiconductors to turn on and turn off circuit and to shape the dimmer output to track the shape of the wave of the incoming power.

    Dimmer Specifications -Racks  DMX Isolation:  All DMX512 & RS485 communication ports and remote contact input connections shall be optically isolated from all processor electronics by a minimum of 2,500V RMS isolation.  Life Safety Code Panic: (Also bridge to Building Fire Alarm System)  The Rack Processor Housing shall have the provision to select any of a maximum of 192 dimmer outputs to be activated by the PANIC function. The PANIC function shall be activated or de-activated by one or more local or remote contact closures.  Dimmer and Processor Speed:  The dimmer control electronics shall have 16 bit (minimum) fade processing and a dimmer update rate better than 16 ms
  • 58.
    Dimmer Specifications -Racks  Line Regulation: The dimmer output levels shall be regulated for incoming line voltage variations. The regulation shall adjust for both RMS voltage and frequency changes of the incoming AC wave form. Regulation shall maintain the desired output voltage +/- .5V volt for the entire operation range (90 – 264 VAC). The regulation shall compensate for variations of the AC waveform on a dimmer-by-dimmer basis.
  • 59.
    Dimmer Specifications -Racks  Output Filtering: Basic Rise dimmers shall have a rise time of not less than 350 microseconds A measured at 90 degrees conduction angle B from 10% to 90% of output wave form C with dimmer operating at maximum load D. Voltage rate of rise (slew rate) must not exceed 420 millivolts per microsecond in any point of the wave under full load conditions
  • 60.
    Dimmer Specifications -Racks  Output Filtering:  2.5.3 Medium rise time dimmers shall have a rise time of not less than 500 microseconds  2.5.4 Hi-Rise dimmers shall have a rise time of not less than 800 microseconds
  • 61.
    Filtering Criteria  A: Rise time- in microseconds, 350 minimum 800 premium  B: Conduction Angle- 90 degree worst case  C: Percentage of waveform 10%-90% conventional, 10%-95% or others is improving spec by increasing amount if waveform measured.  D: Load: Theatrical manufacturers measure at full load, (rarely achieved), other amounts as stated.  E.: Slew Rate, some filters can take adequate overall time, but take too long to respond, for example, and result in noisy lamps.
  • 62.
    Dimmer Specifications -Racks  SINEWAVE Dimmers: Dimmer output waveform shall be a fully symmetrical Sinewave at any output voltage setting eliminating all lamp noise and reducing reflected harmonics on the building power supply. Total Harmonic distortion shall be less than 1% and efficiency shall be 98%.

    Dimmer Specifications -WBD  SPEC From website information – DIMMERS  Manufacturer:  Electrical Specifications – Input: 120 VAC @ 60Hz, 277VAC @ 60Hz OK – Line Voltage Regulation Where is specification???? These can have line regulation, but what is it? – RFI Noise Suppression Sure, but what??? WBD have been measured (by me) at 110 ms, 10-90% 90 degrees, full load. So “De-buzzing” coils (additional chokes) are sold for sensitive situations and loads.  Maximum Load: 120V incandescent: 1500W stand-alone, OK
