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 Fast-acting Damper

Actuation — 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. 570-115 Installation Instructions October 26, 2016 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. NOTE: A low-cost temporary RTS (540-658P25) is available that plugs into the RTS port on the controller, providing temperature input and actual space control until a permanent RTS is installed.

Document No. 570-115 Installation Instructions October 26, 2016 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. 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.

Document No. 570-115 Installation Instructions October 26, 2016 CAUTION 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. A separate power supply is required if a 4-20 mA sensor is used. Failure to follow wiring precautions will result in equipment damage. Wiring for AI with a 4 to 20 mA Sensor. 24 Vac Modulating Control.
