Generic Controller I/O Layout. See Wiring Diagram for application specific details.
Control Applications
6740, 6741 and 6742
Product Description
These instructions explain how to field install or
replace the Fume Hood Controller (FHC).
This BACnet Fume Hood Controls a Fast-acting
Damper or Venturi Air Valve to maintain control of a
chemical fume hood with up to 2 sashes. It uses
fast-acting electronic actuators (shipped separately)
to control the exhaust control device.
WARNING
The application cannot detect a
broken wire to the analog input
for the second sash.
An external sash aggregating
device should be used to
calculate the face area for all
fume hoods with more than one
sash.
This controller supports up to two Offboard AVS
signals. Offboard Air Module(s) (OAM) house AVS
transducers and send signals to the AVS input(s) on
the controller board. The controller can operate
stand-alone, with a field panel, or as part of a
network.

Installation Instructions
NOTE:
All wiring must conform to national and
local codes and regulations (NEC, CE,
etc.).
1. Secure the mounting rail in the controller’s
desired location.
2. Place the ESD wrist strap on your wrist and
attach it to a good earth ground.
3. Remove the controller from the static proof bag
and snap it into place on the mounting rail.
4. If the controller will be used with a field panel,
disconnect the field level network (FLN) trunk
from the field panel.
5. Wire the FLN trunk to the controller. After all
controllers are connected to the FLN, reconnect
the FLN trunk to the field panel.
6. If the controller requires Offboard Air Modules,
install them now following the appropriate
Installation Instructions (see Product Numbers ).
7. Connect the point wiring (see Wiring Diagram s).
CAUTION
DO Wiring –Each DO provides a
Normally Open (NO) terminal and a
Common (C) terminal.
To reduce noise and the potential
for ground loops, both connections
of a 24 Vac load must be wired
directly to the DO terminal on the
controller board.
8.
Plug the operator display cable into the ODP
port.
9.
Connect the power trunk. DO NOT apply
power to the controller without first consulting
the specialist.

CAUTION
It is important that the neutral that
supplies the TEC must be earth
grounded at the source of the 24
Vac power.
Possible erratic equipment
operation or damage if neutral is not
grounded.
ATTENTION
Il est très important que le neutre
qui alimente le TEC soit mis à la
terre à la source de l’alimentation
24 Vca.
Risque de fonctionnement
incohérent de l’équipement ou de
dégats si le neutre n’est pas mis à
la terre.

Regulatory
FCC Statement Part 15.19
This Device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference,
and
2. This device must accept any interference
received, including interference that may cause
undesired operation
FCC Part 15.21, Information to user
Changes or modifications not expressly approved by
the party responsible for compliance could void the
user’s authority to operate the equipment.
FCC Part 15.105, Information to user
This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a residential
installation. This equipment generates, uses, and
can radiate radio frequency energy and, if not
installed and used in accordance with the
instructions, may cause harmful interference to radio
communications. However, there is no guarantee
that interference will not occur in a particular
installation. If this equipment does cause harmful
interference to radio or television reception, which
can be determined by turning the equipment off and
on, the user is encouraged to try to correct the
interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment
and receiver.
Connect the equipment into an outlet on a circuit
different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV
technician for help.

CAUTION
The FHC-OAVS has two terminal
blocks with terminations numbered
identically (terminations 1 through
16). DO NOT get these mixed up
with each other.
If the FHC-OAVS is not connected
as shown, it is not resistant to
electrical surges. It is also
susceptible to interference from
other equipment.
ATTENTION
Le LCM-OAVS est muni de deux
bornes dont les contacts sont
numérotés à l’identique (contacts 1
à 16). NE PAS les confondre.
SI le LCM-OAVS n’est pas
connecté comme indiqué, il n’est
pas protégé contre les surtensions
électriques. Il est également
susceptible à des interférences
émises par d’autres périphériques.

CAUTION
A separate power supply is required
if a 4-20 mA sensor is used.
Failure to follow wiring precautions
will result in equipment damage.
ATTENTION
Une alimentation séparée est
nécessaire, si un capteur 4…20
mA est utilisé.
Risque de dégâts matériels, si
les précautions de câblage ne
sont pas respectées.

Wiring for AI4: Sash Sensor 2.
WARNING
The application cannot detect a broken
wire to the analog input for the second
sash.
An external sash aggregating device
should be used to calculate the face
area for all fume hoods with more than
one sash.
AVERTISSMENT
L’application ne peut pas détecter un fil
rompu allant à une entrée analogique
pour le second châssis.
Un dispositif externe de cumulation de
châssis devrait être utilisé pour
calculer la surface à l’entrée de toutes
les hottes de laboratoire munies de
plus d’un châssis.
WARNING
Must use external 10 Vdc power
supply.
Do not power AI from an onboard AO
that is forced to 10 volts.
AVERTISSMENT
Doit utiliser une alimentation externe
de 10 V.
Ne pas alimenter un AI à partir d’un

Siemens Industry, Inc. Page 7 of 11
CAUTION
Each 4-20 mA sensor requires
a SEPARATE dedicated power
limited 24 VDC power supply.
DO NOT use the same
transformer to power both the
sensor and the controller.
ATTENTION
Chaque capteur 4-20 mA
nécessite un source
d’alimentation SÉPARÉE
limitée à 24 VDC.
NE PAS utiliser le même
transformateur pour alimenter le
capteur et le contrôleur.
NOTE:
If the voltage/current switch is set to
current and a 4 to 20 mA sensor is
connected to an AI, then special wiring
requirements must be followed.
NOTE:
When wiring any actuator that uses a 0 to
10V control signal and ties AC neutral to DC
common, an additional wire must connect
the actuator AC neutral to the DC common
of the PTEC/TEC AO being used to control
the actuator.
