Product Description

These instructions explain how to field install or

replace the BACnet Laboratory Controller Module

LCM.

This BACnet LCM-OAVS VAV Room Pressurization

Controller with HW Reheat and Two Fast-acting

Venturi Air Valves — One Exhaust, One Supply

features VAV control of a laboratory room with one

supply duct, one exhaust duct, and up to six Fume

Hoods. It uses fast-acting electronic actuators

(shipped separately) to control the supply and

exhaust.

This controller is built on a BACnet Programmable

TEC (PTEC) platform that supports up to two

Offboard AVS signals; however, Onboard AVS

transducers are not supported. Offboard Air

Module(s) (OAM) house AVS transducers and send

signals to the AVS input(s) on the LCM OAVS

board.

The LCM can operate stand-alone, with a field

panel, or as part of a network.

Document No. 570-129 Installation Instructions October 26, 2016 CAUTION CAUTION Keep the unit in its static proof bag until installation. Otherwise you run the risk of damage to the printed circuit board from electrostatic discharge. Ne pas retirer la carte de son emballage avant son installion. Autrement, une décharge électrostatique peut endommager la carte équipée.

If the controller will be used with a field panel, disconnect the field level network (FLN) trunk from the field panel. For each Fast Acting Lab Electronic Actuator, verify that the switches are set as shown in Figure Switch Settings for the Fast Acting Lab Electronic Actuator. 5. Wire the FLN trunk to the controller.

Document No. 570-129 Installation Instructions October 26, 2016 CAUTION 6. Wiring Range: 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. 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.

Document No. 570-129 Installation Instructions October 26, 2016 Wiring Diagrams Offboard Air Module Wiring. CAUTION The LCM-OAVS has two terminal blocks with terminations numbered identically (terminations 1 through 16). DO NOT get these mixed up with each other. If the LCM-OAVS is not connected as shown, it is not resistant to electrical surges. It is also susceptible to interference from other equipment.

Document No. 570-129 Installation Instructions October 26, 2016 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. NOTE: The controller’s DOs control 24 Vac loads only. The maximum rating is 12 VA for each DO.
