34Building 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.
35Building Management Systems
- BMS Language
- Points
- AI Analog Input
- AO Analog Output
- BI or DI Binary / Digital Input
- BO or DO Binary / Digital Output
36Building Management Systems
- Analog Input can be variable voltage, current, or
resistance signal. - Analog Output can be variable voltage or current.
37Building 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.
38Building 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.

- Direct Access- i.e. Lutron,
- Interface- Input, output, status feedback,
Bi-directional, Serial Data - RS 232- EIA/TIA Standard, 50 ft. limitation

50Dimmer 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.
51Dimmer 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.
52Dimmer 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.
53Fluorescent Dimmers
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
54Dimmer 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.
55High Density Dimming Systems
56Rack Consideration
- Fault Current Rating
- Size and Mounting
- Cooling
- Fans with Noise
- Convection may require cooler ambient temp
57Dimmer 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
58Dimmer 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.
59Dimmer 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
60Dimmer 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
61Filtering 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.
62Dimmer 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.
63Dimmer Specifications - WBD
- SPEC From website information
- DIMMERS
- Manufacturer
- Electrical Specifications
- Input 120 VAC _at_ 60Hz, 277VAC _at_ 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

67Remember
- Today, Lighting Control is Mandatory in many
cases - Conceive the system by determining loads
separately from control function - Groups always work together, increase load,
simplify programming - Load types, ie Low voltage can affect your
thinking
