Smoke Control Listed BACnet Fume

Hood Controller

Item No. 570-136. Rev. CA Page 1 of 11

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.

Plug the operator display cable into the ODP

port.

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.

Wiring Diagrams

Offboard Air Module Wiring.

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 AI5: Sash Sensor 1.

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

AO forcé à 10 volts.

Wiring for AI with a 4 to 20 mA Sensor.

Document No. 570-136

Installation Instructions

October 26, 2016

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.
