1. INTRODUCTION 1.1. KES ENERGY SAVER Zennio’s 3-channel energy saver, KES, combines in the same device the following features: 3 independent input channels. Each of them can be used to connect a measuring probe (model ZN1AC-CST60) and to perform these actions: ... -

In order to obtain more detailed information about KES technical features, as well as on security and installation procedures, please read the KES Datasheet, included with the original packaging of the device and also available at: http://www.zennio.com. 2. CONFIGURATION 2.1. ACTIVE POWER KES Energy Saver calculates the value of the active power consumed by the device whose phase line passes through the ZN1AC-CST60 probe, connected to one of the KES channels. -

KES will send (if configured) a low-consumption indicator as soon as the power is lower than the lower limit. This indicator will remain active until the power is back again higher than the lower limit plus the margin band. ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com... - Page 8 Overconsumpt. Overconsumpt.

Page 15: Active Energy
This estimation of the active energy consumed is made assuming that the instant power consumption at the moment of the estimation remains constant during the 24 hours of the current day. Figure 3.4. Active energy. Estimations. ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com... - Page 16 (object “[Cx] Last hour energy consumption”) or as the associated cost (object “[Cx] Last hour cost”). These objects will show up once their own parameters have been enabled. ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com...

Page 18: Active Power
From this screen it is possible to configure several parameters related to the consumption of active power (section 2.2). These show up grouped into different sections, as explained below: Instant power. This section is to configure those parameters that affect the sending of the communication object “[Cx] Instantaneous Power”. ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com... - Page 19 “Instant power”, making it possible to inform the bus about how the hourly peak value changes throughout the hour. Regarding daily, weekly and monthly peak values, they can be sent not only at the end of the day / week / month, but also periodically (with their ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com...

Page 20: Power Limit Monitoring
Energy Saver will assume as the upper limit while measuring power. If the value “0” is set, KES will not consider monitoring power in relation to a particular upper limit. The value of the upper limit, however, can be modified in runtime through the communication object “[Cx] ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com... - Page 21 KES will not consider monitoring power in relation to a particular lower limit. The value of the lower limit, however, can be modified in runtime through the communication object “[Cx] Lower limit”. In the case of parameterizing a value other than 0 for this field, it will be as well ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com...
- Page 22 By configuring a certain margin with a value other than 0 (in tens of a watt), every time the low-consumption indicator is triggered, it will be necessary that the measured power reaches upper limit plus margin before further low consumptions trigger the indicator again.

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. ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com... - Page 25 (otherwise, it would assume that it is still 5:15h pm). Since the voltage failure has caused a timing reset of the periodical sendings, the next security sending will happen at 11:00h pm, even if the previous one had taken place at 3:00h pm. ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com...

In such circumstances, the only functions KES will develop are: 1) Sending, every midnight, the objects “Daily energy consumption” and “Daily cost”, expressed in kWh and monetary units, respectively. ZENNiO AVANCE Y TECNOLOGÍA vwww.zennio.com... - Page 28 That’s why the 0.2 kWh mentioned in cost or CO the above example may show up as 0 kWh, although the 0.2 kWh are actually considered for further calculation.

- Page 32 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 line is a bit higher.
