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. 26 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. 26. 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.
2.
Once the terminal block is raised 1/4 in. (6.35 mm) from
its alignment pins, grasp the terminal block at its center
(for long terminal blocks grasp it at each end) and pull it
straight up.
Controller Replacement (PVL0000AS,
PVL4022AS, and PVL6436AS)
For PVL0000AS, PVL4022AS, and PVL6436AS controllers,
which are hard-wired to an actuator, perform the following
actions to replace the complete assembly (controller and
actuator):
1.
Remove all power from the controller.
2.
Remove the two air flow pickup connections from the
pressure sensor.
3.
Remove the terminal blocks (See “Terminal Block
4.
Remove the old controller and actuator assembly from
its mounting.
• Loosen the two bolts on the actuator clamp to release
the actuator from the shaft.
• Remove the controller’s mounting screws.
• Gently pull the controller and actuator assembly
straight out, until the assembly is clear of the actuator
shaft.
5.
Mount the new controller and actuator assembly (See
