    Celsius. If operators are likely to come into contact with such heatsinks, adequate warnings and barriers must be put in place in order to prevent injury. EPack 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.

    EPACK CONTROLLER: USER GUIDE SAFETY NOTES (Cont.) Signal and power voltage wiring must be kept separate from one another. Where this is impractical, shielded cables should be used for the signal wiring. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment might be impaired.

Data values can be left blank or cleared, in which case, no values will be written for those parameters at download. Data values are cleared by deleting all the characters in the cell then either moving to a different cell or typing <Enter>.

    EPACK CONTROLLER: USER GUIDE 8 PARAMETER ADDRESSES (MODBUS) 8.1 INTRODUCTION The iTools address fields display each parameter’s Modbus address to be used when addressing integer values over the serial communications link. In order to access these values as IEEE floating point values, the calculation: IEEE address = {(Modbus address x 2) + hex 8000} should be used.

    EPACK CONTROLLER: USER GUIDE 9.2.4 Over current detection The analogue input over current detection alarm is active. 9.2.5 OverVoltage Alarm An ‘OverVoltThreshold’ can be configured in the Network.Setup area of configuration (section 6.17.2) as a percentage of VLineNominal. If the VLine voltage rises above this threshold the OverVoltage alarm is set.

    EPACK CONTROLLER: USER GUIDE 9.3 INDICATION ALARMS Indication Alarms signal events for operator action if required. Indication alarms cannot be configured to stop power module firing, but they may be latched if required, and if latched, they must be acknowledged for the Signaling Status to return to the normal (non-alarm) state.

    EPACK CONTROLLER: USER GUIDE 10 MAINTENANCE 10.1 SAFETY WARNING BRANCH-CIRCUIT PROTECTION AND SAFETY OVERLOAD PROTECTION This product does not contain any branch-circuit protection or internal safety overload protection. 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.

    EPACK CONTROLLER: USER GUIDE 10.3 FUSING It is recommended that in-line thyristor protection fuses are fitted, according to table 10.3a below. These should beused in conjunction with suitable fuse holders and contact kits (if required) as shown in table 10.3b. The coloured areas indicate which fuses use which fuse holders.

  • Page 104 EPACK CONTROLLER: USER GUIDE A2 SPECIFICATION (Cont.) 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. The phase voltage referred to is the line voltage referenced to N/L2 input potential.
