Withdrawal Notice – ISUPS 300Whr V1

The ISUPS 300Whr V1 was made obsolete in 2017 and has not been manufactured since. We have continued to support this product, however, critical components required for repair are no longer readily available and have increase repair turn around times.

Withdrawal Notice – IPC Product Family

During the lifespan of the IPC Integrated Protection Relay, several key materials that are required to manufacture the products within the IPC family have been made obsolete by their respective manufacturers. As a result, Ampcontrol has been forced to withdraw the IPC range.

Application Note – Earth Leakage Relay Power Up Trip

Ampcontrol has recently been made aware of a condition that causes the ELD V3 and ELV V2 relays to power up into a tripped state. The trip is related to the internal charge of the super-capacitor. The issue may cause delayed power up of equipment as a reset will be required if a trip occurs.

The cause of this trip is not a safety concern nor will it pose any risks to operations experiencing this condition. The trip was detected during the commissioning stage where the equipment was undergoing repetitive power cycles.

Product Update – ECM3 Application Note

If your installation is experiencing nuisance tripping due to DC offset sources, and you are not required to use Earth Continuity Protection for touch potential safety, then the following application note may be a suitable solution. The ECM3 Earth Continuity Relay utilises a DC sense signal to determine the Pilot Series and Shunt Resistance. In some applications where the relay is exposed to DC offset sources (i.e. when exposed to a cathodically protected wharf or pontoon to fight against corrosion), the applied DC source can interfere with the relay’s sensing ability.

Declaration of Conformity – iMAC Controller

In May 2018, the iMAC / iMAC2 Controller operating system firmware was modified to extend the iMAC Module Serial Number range. These changes occurred in iMAC Controller Operating System Firmware v4.0 (O.S. v4.0). Marcus Punch Pty Ltd was engaged to perform a safety integrity verification of these changes. iMAC2 report AMP-15-01-A1 Revision 3 (including Revisions 4 & 5) and iMAC report AMP-11-05-A2 Revision 2 (including Revisions 3 & 4) assessed these changes to be in compliance with the requirements pertaining to software modification and as a result the existing safety metrics (PFD and PFH) for the iMAC Controller, iMAC2 Controller, 2-wire and 3-wire iMAC systems remain unchanged.

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

Product News – iMAC R04 V2

Ampcontrol has released a revised version of the iMAC RO4 module to address component obsolescence issues with the existing module. The all new RO4 module is a completely re-developed module utilising Ampcontrol’s latest iMAC hardware and software platforms. The new RO4 V2 module supersedes and replaces all previous versions of the RO4 module (V0, V1).

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).
