factor is 4 .4 If the line voltage is 277 VAC and the SLQ218
power input is 24 VAC, then the calibration factor is 11.5.
DAYLIGHT SAVING TIME
If Daylight saving is used, simply enable the “Daylight Sav
-
ing Time” option within the software and enter the starting
month + week and the ending month + week .
Programming - Pulse Meter
The utility pulse meter module portion of this panel is an
SEQ100.
METER INPUTS
There are four meter inputs available. Each one is setup for
a dry contact and cannot be changed. Each input (Meter 1,
Meter 2, Meter 3 & Meter 4) can be configured to accept
signals representing electrical, BTU, water or gas usage.
The required parameters will be provided by either the
utility company involved or on the current transducer (CT)
used to generate the pulse signal .
METER TYPES
The SEQ100 supports various meter types . Selecting a
meter type changes the default values as they are used to
calculate meter consumption and demand for that particu-
lar meter. For each of the four SEQ100 meter inputs, there
are five selectable options:
ELEC 1 PH: Electric single phase meter.
ELEC 3 PH: Electric three phase meter.
GAS: Gas meter .
WATER: Water meter
BTU: BTU meter
Utility pulse meters can be one of two different types,
depending on whether they count the leading and trailing
edges of the pulse or only the leading edge of the pulse as
If you have a Type C device (3 terminals KYZ), you will
need to double the multiplier. The SEQ100 only counts the
contact closures for the K and Z terminals. Doubling the
multiplier will correct this problem.
PROGRAMMING THE METER CONSTANTS:
CT Value: The value of the CT wired to the meter . This
value is usually provided on the CT or on the utility output
meter . This value is only used for and electric meter .
P/REV: The Pulses per revolution for the meter . This value
is usually provided from the utility company .
CONSTANT: The value of the constant for the meter is usu-
ally provided from the utility company and many times is
located on the electric or gas bill.
CU FT/P: The value for Cubic Feet per pulse. This only
applies to Water, GAS and BTU, and is usually found on the
utility meter itself .
MULT: The multiplier for the meter can be used to scale
the meter output or correct for KYZ meter . The multiplier
is used to convert the pulses to engineering unit data . For
example, if your meter provides one pulse per 0.01KWH,
then a constant of 0.01 is required.
MULTIPLIER:
Each model of power meter is different and has a different
multiplier. For example, if the meter is a Type A and reports
1/10 kWh per pulse, set the input multiplier to 0.1. If the
meter is a Type C and reports 1/10 kWh per pulse, set the
input multiplier to 0 .2 .
a single count. A pulse output can be either a mechanical
relay or solid state device . The pulse output corresponds
to a unit/time of a monitored quantity. The amount of time
between states of a pulse output corresponds to the meter
demand and the number of pulses is proportional to the
meter’s consumption.
Below is a diagram depicting two types of utility meter
pulse outputs . Meter Type A counts only the leading
edge as a single pulse and the trailing edge is ignored .
Meter Type C is known as a true KYZ meter and counts
both the leading and trailing edges as a pulse, effectively
doubling the number of pulses as seen by Meter Type A.
The SEQ100 measures Type A output only; however, KYZ
functionality can be mimicked by using a “Meter Multiplier”
value of 2 .
In the following picture, both Type A and C are shown.
Three pulses are shown, labelled 1, 2, and 3. Notice how
the Type A output closes and opens for each pulse, where
the Type C output simply changes state .
