User Manual – Outlet Test System (OTS)

The Ampcontrol Outlet Test System (OTS) and Outlet Test System – Earth Leakage (OTS-EL) provide a fully automated testing facility. The OTS completely eliminates paper-based record keeping by concurrently updating a historical database with the latest test data. The OTS (or OTS-EL) is comprised of an OTS module, embedded within the outlet electrics, and an OTS Comms Module, mounted on the door to provide Bluetooth connectivity to the Tester. The full OTS module will test the outlet’s earth leakage, earth continuity, earth fault lockout and frozen contactor protection functions while the OTS-EL version will limit testing to earth leakage protection only.

All tests, for both the OTS and OTS-EL, are initiated wirelessly via the OTS Application Software, which is installed on compatible Bluetooth enabled devices. Each outlet is able to be individually targeted to prevent incorrect outlet testing. The test record for each outlet is managed within the OTS Application Software, with all records automatically uploaded to cloud storage when the tablet gains network access. All test records for any OTS equipped outlet on a site can be accessed by anyone with internet access, user ID and password.

Technical Datasheet – ELM V2 Relay

The Ampcontrol ELM V2 earth leakage relay has been designed and approved for use on earth fault limited systems providing earth leakage protection (earth fault protection). The relay is also suitable for other applications where equipment or system earth leakage protection is required.

Technical Datasheet – ELD V3 Relay

The Ampcontrol ELD V3 earth leakage relay has been designed and approved for use on earth fault limited systems, namely coal mining applications, providing earth leakage protection (earth fault protection) as per AS/NZS 2081:2011. The relay is also suitable for other applications where equipment or system earth leakage protection is required.

User Manual – ELM V2 Relay

The Ampcontrol ELM V2 Earth Leakage Relay is electronic in design and is based on microprocessor technology. The earth fault current is measured using a toroid, with the trip time and trip threshold being able to be independently adjusted using selectors on the relay fascia. When a fault occurs and the trip level and time delay is exceeded the relay‟s trip function is activated. A trip will de-energise the trip contacts connected in the system control circuit. The trip condition is latched in non-volatile memory and requires operation of the reset input to clear the trip condition. An internal reset is also provided on the fascia of the relay.

Product Update – EL Relay

Some of the relays components are experiencing obsolescence issues, and have been updated to ensure continued production. New item numbers for the current discrete Earth Leakage Relays have been allocated to facilitate these changes. The functionality, form and fitment of these relays remains unchanged

Technical Datasheet – Outlet Test System (OTS)

The OTS System is installed into Ampcontrol Substations, Distribution Boards and Outlet Control Boxes. The OTS greatly simplifies the statutory testing process, performing a hands-free, automated testing function whilst simultaneously providing a comprehensive record management tool.

Obsolete Relays Repair Notice – 25.11.16

A number of Ampcontrol electrical protection relays which have already been made obsolete, and not manufactured for some time, will no longer be repaired (WN-2016-04). This is because a number of critical components required for repair are no longer available. The effected products are outlined in the notice along with the replacement series (if applicable).

Service Bulletin – IP and EL Relays

Updated Installation and overhaul requirements of Ampcontrol integration protection and earth leakage relays. The following information has been added to the IP relay user manuals maintenance section. This has been included due to equipment being returned to AS3800 RSF’s and the IS components not being overhauled and then returned to service, only for the user to experience nuisance tripping, reliability issues and or failure shortly thereafter.
