Disconnect power supply before beginning controller
replacement to prevent electrical shock or equipment
damage.
Terminal Block Removal
To simplify controller replacement, all terminal blocks are
designed to be removed with the wiring connections intact and
then re-installed on the new controller. See Fig. 24 and refer to
the following procedure:
IMPORTANT
To prevent bending or breaking the alignment pins on
longer terminal blocks, insert the screwdriver at
several points to evenly and gradually lift up the
terminal block.
Insert the screwdriver blade no more than 1/8 in.
(3 mm) to prevent damage to the terminal block align-
ment pins on the controller circuit board.
Fig. 24. Removing Terminal Blocks.
1. Use a thin-bladed screwdriver to evenly raise the
terminal block from its alignment pins:
a. For short terminal blocks (1 to 5 terminals), insert
screwdriver blade in the center of the terminal block
and use a back and forth twisting motion to gently
raise the terminal block from its alignment pins 1/4 in.
(6.35 mm).
b. For long terminal blocks (6 or more terminals), insert
screwdriver blade on one side of the terminal block
and gently rotate the blade 1/4 turn. Then, move to
the other side of the terminal block and do the same.
Repeat until the terminal block is evenly raised 1/4 in.
(6.35 mm) from its alignment pins.
