EPower alarms protect thyristors and loads against abnormal operation, and provide the user with valuable information regarding the type of fault. Under no circumstances should these alarms be regarded as a replacement for proper personnel protection.
Page 16 EPOWER CONTROLLER USER GUIDE SAFETY NOTES (Cont.) If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment might be impaired. In order to maintain protection against electrostatic discharge, any scratched or damaged inter- module ribbon cables must be replaced.

USER GUIDE 1 INTRODUCTION This document describes the installation, operation and configuration of an EPower ‘station’ (Driver Module plus one or more Power Modules). The Driver Module comes in one version, but the Power Modules are available in a number of different power ratings, which are identical in operation and configuration, but which differ in physical size according to the number of phases being controlled and the maximum current being supplied.

Page 189: Predictive Load Management Option
EPOWER CONTROLLER USER GUIDE 9 PREDICTIVE LOAD MANAGEMENT OPTION 9.1 GENERAL DESCRIPTION The Predictive Load Management (PLM) system is an assembly of a number of units (‘stations’) working together in order to minimize transient power demands which could appear on the mains if all the units were independent.
Page 190: Power Modulation And Accuracy
EPOWER CONTROLLER USER GUIDE 9.1.2 Power modulation and accuracy Fixed modulation is automatically selected for all channels participating to the Load Management. The Modulation period T is constant and is selected (between 50 and 1000 mains periods) during configuration. ...
Page 191: Load Sequencing
EPOWER CONTROLLER USER GUIDE 9.2 LOAD SEQUENCING Load sequencing is a time-dependent distribution of Energy through the Load (independent of the installed power per load) in order to avoid big spikes of power demand at the beginning of each conduction period.
Page 192: Incremental Control Type 2
EPOWER CONTROLLER USER GUIDE 9.2.2 Incremental control type 2 This kind of control, is similar to Incremental control type 1, but the modulated channel is always channel 1. Other channels are always either at 100% (Full conduction) or at 0% (No conduction). The total power distributed to the Loads is equal to the Setpoint.
Page 193: Rotating Incremental Control
EPOWER CONTROLLER USER GUIDE 9.2.3 Rotating Incremental control This kind of control, is similar to Incremental control type 1, but the modulated channel varies. Non- modulating channels are always either at 100% (Full conduction) or at 0% (No conduction). The total power distributed to the Loads is equal to the Setpoint.
Page 194: Distributed Control
EPOWER CONTROLLER USER GUIDE 9.2.4 Distributed control With this kind of control, each Load has its own setpoint. In order to avoid simultaneous firing in more than one load, the modulation periods are staggered by a time given by  = T/N, where T is the modulation period configured by the user, and N is the number of channels.
Page 195: Rotating Incremental Distributed Control
EPOWER CONTROLLER USER GUIDE 9.2.5 INCREMENTAL DISTRIBUTED CONTROL (Cont.) Similarly for the five channels in group 2, assuming a setpoint of 35% (i.e. unput of the first channel of group 2 =0.35), Channel G 1 modulates at 75%; G 2 is continuously on and G...

Page 198: Load Shedding
EPOWER CONTROLLER USER GUIDE 9.4 LOAD SHEDDING Load Shedding controls the total power distribution amongst loads by reducing the amount of Power distributed for each load so that the global power demanded is less than a given maximum (Ps). Load Shedding and Load Sharing may be used together if required.

EPOWER CONTROLLER USER GUIDE 9 4 2 REDUCTION OF POWER DEMAND (Cont.) The resulting Power for a given channel (i) is: = r x  x Pt The parameter Pr is available to the user as ‘PBurst’ in the Block ‘Network.Meas’ for each channel.

This is the case where a shed factor has been applied to one or more channels. Alternatively, the alarm may be caused by the false calibration of one or more channels.
Page 214: Alarms
EPOWER CONTROLLER USER GUIDE 10 ALARMS 10.1 SYSTEM ALARMS System alarms are considered to be ‘Major Events’ which prevent proper operation of the system, and the relevant module is placed in standby mode. In some configurations (e.g. four × single-phase) it is possible that a system alarm generated in one power module will set only that module into standby mode, and the other three phases will continue as normal.
Page 215 EPOWER CONTROLLER USER GUIDE 10.2 PROCESS ALARMS Process Alarms are related to the application and can be configured either to stop the power module firing (Standby Mode) or to allow operation to continue. Process alarms can also be configured to be latched and if so, they have to be acknowledged before the alarm is considered to be non-active.
Page 216 EPOWER CONTROLLER USER GUIDE 10.2.6 Partial Load Failure (PLF) See also ‘PARTIAL LOAD FAILURE CALCULATIONS’ in section 6.20.2. This alarm detects a static increase in load impedance by comparing the reference load impedance (as configured by the user) with the actual measured load impedance over a mains cycle (for phase angle firing) and over the burst period (for burst and logic firing).

MAINS NETWORK MEASUREMENTS All network measurements are calculated over a full mains cycle, but internally updated every half-cycle. For this reason, power control, current limits and alarms all run at the mains half-cycle rate. The calculations are based on waveform samples taken at a rate of 20kHz. Measurements on each phase are synchronised to its own phase and if the line voltage cannot be detected, the measurements stop for that phase.

It is the responsibility of the user to add branch-circuit protection upstream of the unit. It is also the responsibility of the user to provide external or remote safety overload protection to the end instal- lation.

EPOWER CONTROLLER USER GUIDE 12.3 THYRISTOR PROTECTION FUSES The thyristors in the Power modules are protected against excess currents by high-speed fuses within the power modules. See table 12.3 for details. WARNING The internal fuses provide protection for the Power modules against load short circuits, and may not be considered as providing any kind of branch-circuit protection.

The 32h8e normally forces the display to return to the Home page after a period of keyboard inactivity. If, however, the current focus is on an EPower parameter, then the HOME Page timeout is not imposed, thus allowing the user to display a specific Network parameter indefinitely (providing that auto-scrolling is disabled).
