Modular Equipment Controller (MEC)

Product Description

The Modular Equipment Controller (MEC) is a field

panel device that mounts to a stable vertical surface

or inside an MEC enclosure. The MEC contains a

processor and memory, and can communicate with

other field panels on the Building Level Network

(BLN). Digital and analog point blocks are also

available for point expansion.

The MEC with HAND-OFF-AUTO (HOA) enables

digital outputs to be manually placed into HAND

(ON), OFF, or AUTO control. Analog outputs can be

placed into AUTO control and nine manual control

positions. Digital and analog point blocks with HOA

control switches are available for point expansion.

MEC Models 200F, 210F, 300F and 310F provide

Floor Level Network (FLN) communication ports and

higher performance.

MEC Models 101 and 201 provide 16 DIs, 8 AIs,

4 DOs, and 4 AOs; HOA switches are not available.

MEC Model 310FB adds BACnet

support to the

MEC 310F feature set.

For more information on MEC hardware and

applications, see the Modular Equipment Controller

Owner’s Manual (125-2183).

Document No. 586-280 Installation Instructions Rev. 1, March, 2002 Verifying Correct Functioning of Switches For MECs with HOA, a green LED is located below the HOA switches. The LED flashes after start-up, indicating that the switches are in the AUTO position and are functioning correctly. If any control switch is moved out of AUTO, the light will stop flashing and remain on.
