Rockwell Automation 1336S PLUS II Control Board Replacement Inst. - Manual

Instructions
This publication will guide you through replacement of the Main Control
Board on 1336 PLUS
II Adjustable Frequency AC Drives.
Replacement Procedure Important: If parameters were not previously uploaded to a HIM with Upload/
Download Capability, it is recommended that they be uploaded
now, if possible. This will allow downloading after the new board
has been installed, thus preventing complete re-programming.
Refer to the figure on page 2 for component locations.
1. Remove and lock-out all incoming power to the drive.
2. Remove/open front cover or remove entire enclosure (on smaller drives)
as required for adequate access.
3. If a HIM (or other snap-in module) is installed, remove it by carefully
squeezing the locking tabs in and pulling out.
4. If a Communications Option (1336-GM1, etc.) is installed in the Adapter
6 location, remove it and transfer it to the new Main Control Board.
5. If a Control Interface Board (L option) is installed, carefully remove the
board by loosening the 2 captive screws. Position the board and attached
wires off to the side of the chassis.
6. If a Control Interface Board is not present, transfer the jumpers at pins 3
& 4 and 17 & 18 of J2 to the same location on the new Main Control
Board.
7. Remove the screws securing the HIM cradle. Remove the cradle.
8. If an Analog Interface Board (LA1, LA2, etc.) is installed in Slot A or B,
note placement and carefully remove the board by releasing standoffs and
lifting straight out. Transfer this board (and standoffs, if needed) to the
same slot on the new board. Repeat if a second board is present.

ATTENTION: This drive contains ESD (Electrostatic Discharge)
sensitive parts and assemblies. Static control precautions are re-
quired when installing, testing, servicing or repairing this assembly.
Component damage may result if ESD control procedures are not
followed. If you are not familiar with static control procedures,
reference publication 8000-4.5.2, “Guarding Against Electrostatic
Damage” or any other applicable ESD protection handbook.
!
ATTENTION: To avoid a shock hazard, assure that all power to
the drive has been removed before proceeding with the following
procedure. In addition, verify that the DC bus has discharged by
measuring across the “+DC” and “–DC” terminals of TB1 with a
voltmeter. The voltage should be 0.0VDC.
