8. RESTART PROCEDURE
8.1 INTRODUCTION
The procedure described below is necessary to restore the 8000 Series System to
full operation after a total loss of power including the loss of the incoming power
supplies. The sequence is based on the assumption that the incoming power
supplies have been restored after all the MCBs, contactors and isolators have been
opened. It is assumed that all the application software and system INI configuration
have been installed.
Note
(1) Before powering the system, ascertain the status of the plant and ensure
that no danger to personnel or damage to the plant will occur.
(2) It is recommended that the 8000 Series System should always be
powered up in this sequence from cold.
(3) The last item to be powered–up will be the two Controller chassis.
8.2 POWER UP PROCEDURE
(1) Ensure that any system or devices attached to the system are ready for the
powering sequence.
(2) Open the 8000 Series System Cabinet doors to gain access to the incoming
240VAC system isolators. Ensure that the supply voltage is a nominal
240VAC. Close the 240VAC isolators.
(3) Close all the 240VAC MCBs. Check that both the 8000 Series System Power
Supply chassis are powered.
(4) Power the fan trays and roof fan assemblies, by closing the pairs of 24VDC
MCBs located on the MCB Panel.
(5) Power the main 8000 Series System I/O Chassis by closing the associated
pairs of 24VDC MCBs located on the MCB Panel.
(6) Finally, power the 8000 Series System Controller Chassis by closing the
associated pairs of 24VDC MCBs located on the MCB Panel.
(7) Close the 240VAC Utilities Assembly MCBs mounted in the 8000 Series
System Cabinets.
(8) Ensure that the 8000 Series System Engineering Workstation has power (if
applicable).
8.3 8000 SERIES CABINET
(1) Press the reset pushbutton on the 8000 Series System Processor Modules.
(2) Ensure that all 8000 Series System Modules are healthy, and that the 8000
Series System PLC is communicating.
(3) Close and lock all doors.
