Page 7: Kes Plus Use Cases In Different Types Of Installations
KES Plus 1.2.2 KES PLUS USE CASES IN DIFFERENT TYPES OF INSTALLATIONS The following figures show the connection diagram of KES Plus in different types of installations: Case 1: Three-phase installation with accessible neutral wire and three-phase load Three- phase load Parameter setting as three-phase system (see section 0). - Page 8 KES Plus Case 3: Single-phase installation with accessible neutral wire or two-phase with ≤230V Línea Parameter setting as single-phase system (see section 2.2.2). For two-phase systems: Phase voltage ≤ 230V Figure 4 Single-phase system with accessible neutral wire or two-phase system.
- Page 9 Figure 6 Three-phase system without accessible neutral wire and single-phase loads. In this case, since two KES Plus are used, the power measurements per phase can be added together using a logic function (section 2.6) to obtain total (three-phase) power measurements, provided they are set in kW.

Page 16: Visual Notification
KES Plus 1.6 VISUAL NOTIFICATION KES Plus includes four LED indicators which provide information of the consumption in each of the phases in single phase systems or the consumption of the three phases in three-phase systems. The LEDs are bicolour. The colour indicates whether there is consumption or generation of energy in the phase: Yellow LED: consumption of energy. -

Page 33: Tariffs
KES Plus 2.3 TARIFFS For every register, it is possible to calculate the monetary cost of the accumulated consumption/generation, together with the consumption corresponding to each tariff, in case of a time-slot based tariff system. Thus, it will be possible to configure up to six tariffs, being also possible to modify them through object. - Page 34 KES Plus For each tariff enabled consumption and cost (or income) communication objects are added for each tariff. For example, for tariff 1: ➢ “[Trf1] [TR] Tariff Consumed Active Energy” ➢ “[Trf1] [TR] Tariff Generated Active Energy” ➢ “[Trf1] [TR] Tariff Inductive Reactive Energy”...

Page 35: Notifications
KES Plus 2.4 NOTIFICATIONS Notifications in KES Plus consist in sending a binary object to the KNX bus when the selected variables, stored in either total or partial registers, reach a pre-set value. The variables on which it is possible to configure notifications are consumption, generation, cost and CO emissions, for global magnitudes and 3-phase systems. -
