Controller Replacement (CLLYVL0000AS,
CLLYVL4022AS, and CLLYVL6436AS)
In the case of the CLLYVL0000AS, CLLYVL4022AS, and
CLLYVL6436AS controllers (which are hard-wired to an
actuator), perform the following actions to replace the com-
plete 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 section “Terminal Block
Removal”).
4) Remove the old controller and actuator assembly from its
mounting.
a) Loosen the two bolts on the actuator clamp to
release the actuator from the shaft.
b) Remove the controller's mounting screws.
c) 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
section “Installation” on page 2).
6) Reconnect the two air flow pickup tubes to the pressure
sensor (see section “Piping (CLLYVL0000AS,
CLLYVL4022AS, and CLLYVL6436AS,
CLLYVL6438NS)” on page 6).
7) Replace the terminal blocks:
a) Insert each terminal block onto its alignment pins.
b) Press straight down to firmly seat it.
c) Repeat for each terminal block.
8) Restore power to the controller.
9) Perform procedure described in section “Checkout” on
page 14.
