Note: The integrated actuator has a stroke
time of 60 seconds for 90° of travel with a 60Hz
power source. The stroke time is the amount
of time (in seconds) that it takes the actuator
to move from the fully closed to fully opened
position or from fully open to fully closed
position. For proper operation, the actuator
stroke time must be configured in the CCT
application based on the actual time it takes
the actuator to drive the damper. The default
setting is 60 seconds (for 90° VAV boxes). For
45° and 60° VAV boxes, the actuator stroke time
must be adjusted. Refer to Controller Tool Help
(LIT-12011147) for instructions on setting the
actuator stroke time in the application.
8. All models are compact in size and are easily
installed on VAV boxes. The models have either a
round shaft up to 13 mm in diameter or a 10 mm
square shaft. Tighten the square coupler bolt to the
shaft using an 8 mm (5/16 in.) wrench or 10 mm (3/8
in.) 12-point socket. Tighten to 10.5 to 11.5 N·m (95 to
105 lb·in).
9. Loop the pneumatic tubing (supplied by field
personnel) to include a trap for condensation. Attach
the needed length of tubing (supplied and installed
by field personnel) to the dual port fitting on the
controller and the other ends of the tubing to the
pressure transducer in the VAV box application .
Note: The CVM/CVE uses a digital pressure
sensor with bidirectional flow operation, which
allows you to connect the high- and low-
pressure DP tubes to either barbed fitting
on the controller. You do not need to make a
specific high- or low-side connection when you
attach the tubing to the barbed fittings on the
CVM/CVE.
10. Push the Manual Override button, and turn the
actuator coupling manually to ensure that the
actuator can rotate from full-closed to full-open
positions without binding.
11. Complete the mounting by rotating the damper to
the full-open position.
CAUTION
Risk of Property Damage.
Rotate the damper to the full-open position before
starting the air handler. Failure to rotate the damper to
the full-open position may result in damage to the VAV
box or ductwork when the air handler is started.
ATTENTION
Risque de dégâts matériels.
Faire pivoter le registre pour le placer en position
d'ouverture complète avant de démarrer l'unité de
traitement d'air. Le non-respect de cette directive
risque d'endommager le caisson de l'unité à volume
d'air variable (VAV) ou le réseau de conduites au
démarrage de l'unité de traitement d'air.
Wiring
Observe the following guidelines when wiring a CVM/CVE
controller:
CAUTION
Risk of Electric Shock.
Disconnect the power supply before making electrical
connections to avoid electric shock.
ATTENTION
Risque de décharge électrique.
Débrancher l'alimentation avant de réaliser tout
raccordement électrique afin d'éviter tout risque de
décharge électrique.
Important: Do not connect supply power to the
controller before finishing wiring and checking all
wiring connections. Short circuits or improperly
connected wires can result in damage to the
controller and void any warranty.
Important: Do not exceed the controller electrical
ratings. Exceeding controller electrical ratings can
result in permanent damage to the controller and
void any warranty.
Important: Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations.
Important: Electrostatic discharge can damage
controller components. Use proper electrostatic
discharge precautions during installation, setup, and
servicing to avoid damaging the controller.
For information on configuring and wiring a BACnet/
IP network, refer to theFX MS/TP Communications Bus
Technical Bulletin (LIT-12011670).
