Sageon II 200A (N+1) Power Distribution System
PM990-5202-200, Rev. 6
6-5
It is recommended that if you have not previously recorded system configuration values and the SCU is
functioning, do so now before performing the replacement.
Alternatively, download the SCU configuration to either a local PC plugged into the operator panel USB
connector or a remotely connected PC. If the SCU is malfunctioning and you believe the configuration
values may not be correct, save the file under a new filename to prevent overwriting earlier good data.
(Sageview system monitor software must be installed in the PC.)
If the SCU is not functioning, the replacement unit will power up with the configuration stored on the
SCU backplane, which can then be edited from the operator panel or a PC.
To remove the Controller Assembly
1.
Check that a known good replacement controller Assembly is on-hand for immediate installation.
2.
Lift the locking mechanism and remove the SCU.
3.
Re-install the new SCU
6.6 REPLACING A RECTIFIER BACK PLANE BOARD
1.
The system must be powered down to replace a rectifier back plane board.
IMPORTANT:
Each rectifier position address must be unique; do not use an address number more
than once. Addresses must be in numerical order with the uppermost (in the system) rectifier having
address 1. The address number increases by 1 with each rectifier installed.
2.
To install the rectifiers, go to Section 2.13, Installing and Removing rectifiers.
