Page 9: Active Energy
KES 3xSingle-Phase 2.2 ACTIVE ENERGY Based on successive values of the instant power, KES can perform the count of the total energy consumed per hour, day, week or month, as well as calculating daily, weekly and monthly average consumptions. KES can also make estimations of the energy that would be consumed during a whole day if the current value of the instant power were kept constant for 24 hours. - Page 10 KES 3xSingle-Phase Overconsumption Overconsumption consumption consumption alarm OFF alarm ON alarm ON alarm OFF Upper limit Deadband Deadband Lowerlimit Figure 5 Power limit monitoring.

Page 11: Ets Parametrization
3 ETS PARAMETRIZATION For beginning with the parameterization of KES it is necessary, once the ETS program has been opened, to import the product database (KES 3xSingle-Phase application program). Next, the device must be added to the project where desired. Right-clicking on the name of the device will display the “Edit parameters”... - Page 12 KES 3xSingle-Phase corresponding ETS fields. After that the measuring and calculating process will start again. The value “0” written to this object will have no effect. Regarding “Global Request”, the value “1” through this object will cause an extra sending of all the communication objects related to the power consumption –of every input channel that has been enabled–...

Page 13: General Window
KES 3xSingle-Phase 3.2 GENERAL WINDOW The General screen, shown in Figure 8, permits the definition of generic parameters for the operation of the energy saver, as well as specifying which channels (A, B, C) have a ZN1AC-CST60 probe connected for measuring energy consumptions. - Page 14 KES 3xSingle-Phase Note: the value shown by default (0.5 kg CO /kWh) is approximately similar to the regular ratios in Europe. It is always possible to change it by entering accurate values for the system to be monitored or by directly setting the exact...

Security sending of last daily values: allows enabling the periodic re- sending of values related to the previous day, being possible to select cycle times of 1, 2, 3, 4, 6 or 12 hours (choosing “0”...
- Page 16 KES 3xSingle-Phase Sending of daily, weekly and monthly peak power values: allows enabling the periodic sending of the instant (updated) values of the daily, weekly and monthly peak power, being possible to select a cycle time of 1, 2, 3, 4, 6 or 12 hours (choosing “0” disables this sending). This way, the peak power values enabled under the “Active power”...

Page 17: Channels
KES 3xSingle-Phase 3.3 CHANNELS Channel screens will show for the first time as follows: Figure 9 Channel. It is possible to independently enable the parameters Active Energy, Active Power and Power Limit Monitoring for each active channel. Moreover, after enabling a certain channel, three new 1-bit communication objects will come up per channel: “[Cx] Reset”, “[Cx] Request”... - Page 18 KES 3xSingle-Phase For its part, “[Cx] Disable” allows enabling or disabling power measures (according to the KNX standard, “0” corresponds to disabling the measurement and “1” corresponds to enabling it) from channel “x”. When this measuring has been disabled, cyclic sending of the instant power is interrupted (in case this had been previously parameterized), and the measured consumption will be considered zero from that moment.

Page 19: Active Energy
KES 3xSingle-Phase Note: the screen captures shown will refer to the configuration of Channel B. Similar parameterization and behaviours can be assumed for channels A and C. 3.3.1 ACTIVE ENERGY This screen allows the configuration of several parameters related to the consumption of active energy (section 2.2). - Page 20 KES 3xSingle-Phase to a change of the value. Valid times are [5-255] seconds. This minimum time between sendings will only take effect if a value other than 0 is parameterized for the fields “Cycle time” or “Send on Value Change”.
- Page 21 KES 3xSingle-Phase (kgCO ). These objects are: “[Cx] Daily Energy Consumption”, “[Cx] Daily Cost” and “[Cx] Daily CO2 Emissions”. It is also possible to enable the sending of objects representing daily average values: “[Cx] Average Daily Energy Consumption”, “[Cx] Average Daily Cost” and “[Cx] Average Daily CO2 Emissions”.
- Page 22 KES 3xSingle-Phase Note: objects referring to Average Weekly values (energy consumption, cost or CO emissions) represent the total consumption (in kWh, local currency or kgCO ) of the week divided by the number of days of the week. In other words, they represent the average consumption per day during the last week.

Page 23: Active Power
KES 3xSingle-Phase 3.3.2 ACTIVE POWER Figure 11 Active power. From this screen it is possible to configure several parameters related to the consumption of active power (section 2.1). These are shown grouped into different sections, as explained below: Instantaneous power. This section is for configuring the parameters that affect the sending of the communication object “[Cx] Instantaneous Power”,... - Page 24 KES 3xSingle-Phase Note: if the value specified here (x) is lower than the minimum time between sendings (y), the latter will prevail, resulting in sendings taking place only every “y” seconds. If “0” is parameterized for “Cycle time”, no periodic sending of the associated communication object will take place.

Page 25: Power Limit Monitoring
KES 3xSingle-Phase 3.3.3 POWER LIMIT MONITORING From this screen it is possible to configure several parameters related to the monitoring of power consumption in relation to upper and lower limits (section 2.3). Two different sections can be found, one for configuring the parameters of the upper limit and one for configuring the parameters of the lower one. - Page 26 KES 3xSingle-Phase Initial value: allows setting (in tens of a watt) the value that, at least in the beginning, the energy saver will assume as the upper limit while measuring power. If this is set to value “0”, KES will not monitor whether the power consumption exceeds or not a particular upper limit.
- Page 27 KES 3xSingle-Phase Initial value: allows setting (in tens of a watt)the value that, at least in the beginning, the energy saver will assume as the lower limit while measuring power. If this is set to value “0”, KES will not monitor whether the power consumption becomes or not lower than a particular lower limit.

Page 28: Logical Functions
KES 3xSingle-Phase 3.4 LOGICAL FUNCTIONS This functionality in KES is provided to make it possible to perform arithmetical operations or in binary logic with incoming data from the KNX bus, so that the result is then sent through other communication objects specifically enabled in the device for this operation. -
Page 29: Annex I: Time Management
KES 3xSingle-Phase ANNEX I: TIME MANAGEMENT As shown in section 3.1, the objects “Date” and “Time” are displayed by default in ETS when the device is configured. These two objects are aimed to set KES to the date and time of an external KNX clock. However, KES features its own built-in clock,... - Page 30 KES 3xSingle-Phase Example II: If one security sending has been defined for every two days and a parameter download (as well as the consequent time set) takes place on Monday at 10:25h am, the first sending will be received on Wednesday at 0:00h am (that is, two day changes after the parameter download), not at 10:25h am on Wednesday.
- Page 31 KES 3xSingle-Phase On the other hand, it must be also remarked that bus failures will reset the timing for the periodical sendings, which is anyway conditioned to the behaviour described in the two previous examples. Example V: A security sending is parameterized for every six hours. A parameter download takes place at 9:25h am, after which the internal clock is set to the current time.
- Page 32 KES 3xSingle-Phase Example VII: A periodic sending has been parameterized for every three hours. The device has been turned on and the internal clock has been correctly set. As soon as it is 3:00h am the periodic sending takes place. However, assuming it is the day when the clock jumps backward an hour for daylight saving, after such sending the external KNX clock will send an order to the internal clock to jump back to 2:00h am.

Page 33: Annex Ii: Further Examples
KES 3xSingle-Phase ANNEX II: FURTHER EXAMPLES With the aim of making clearer how KES works and of presenting the multiple parameterizable communication objects in their context, a few more examples will be offered next. They are intended to cover exhaustively enough most of the doubts that may rise during the initial contact with the device. - Page 34 KES 3xSingle-Phase For simplicity, the probe can be supposed to be measuring the consumption of a 100- watt bulb, as well as a certain month with 22 workable days –during which the bulb is on between 8h in the morning and 6h in the afternoon– and 8 non-workable days –...

- Page 36 KES 3xSingle-Phase CASE 4 In the case of having no consumption during a whole day (note that a null consumption is a very remote situation) although the channel stayed enabled, KES will do take into account that day for the weekly calculation. For example, assume that there was a...

Exactly after midnight, the channel is enabled again and remains this way indefinitely, measuring a 200 Wh consumption every hour.
- Page 38 KES 3xSingle-Phase Example V: tariffs. The following tariff parameterization has been downloaded to KES: - Initial value for Tariff 1: 15 (cents) - Initial value for Tariff 2: 16 (cents) - Initial value for Tariff 3: 0 (cents) - Initial value for Tariff 4: 0 (cents) Assume an instant power consumption of 2 kW and that KES gets switched on at midnight.
- Page 39 KES 3xSingle-Phase If a power factor of 90% is parameterized, the values sent by KES to the bus in relation to power and energy will correspond to those actually consumed by the system, although the amount of effective energy that is really transmitted by the monitored line is a bit higher.
- Page 40 KES 3xSingle-Phase 3) If the value decreases to 1.78 kW, the inverted value (“0”) will be sent through object “[Cx] Over-consumption alarm”. If after that it increases again to over 2 kW, one “1” will be sent through the same object.

Active Energy screen: values 5, 30 and 0 for section “Estimated energy consumption”. Values 5, 30 and 0 for section “Estimated cost”. Any other parameters, enabled.
- Page 42 KES 3xSingle-Phase consumption of 0 kW. Therefore, KES estimates that between 9:00h and 10:00h there should have been, proportionally, a consumption of 1 kWh. Last hour cost ≈ 50 monetary units. 50 is the cost corresponding to the kilowatt-hour that was estimated by the device for the period 9:00h to 10:00h.
- Page 43 KES 3xSingle-Phase 5) After some minutes since 4), set the internal clock to next Monday (any time would be OK), maintaining the 2000 W load. Weekly energy consumption = 5. According to the device, the last week was only 2 day long (with a different amount of hours each and with a different length each of these hours).
- Page 44 KES 3xSingle-Phase 5 kWh were consumed at 50 monetary units per kWh, which is then divided by the two days of the previous week. 6) After some minutes since 5), set the internal clock to next Monday (any time would be OK), maintaining the 2000 W load.
