Hardware

Controllers

Several styles of controllers provide flexibility and expansion to meet application needs.

Power MEC Controller – 11xx

In addition to building and system management functions, this controller provides control of the 32 points contained on the input/output point board.


In addition to control of the 32 points on the

Input/output point board, this controller supports analog and digital point expansion modules, which can be mounted remote from the controller. This capability expands the point capacity of the Power

MEC and provides for cost-effective placement of the point terminations close to the load.


In addition to building and system management functions and point expansion this controller supports connection to Insight using a dial-up modem or an

APOGEE Ethernet Microserver. This allows use of the

Power MEC in applications that are remote from the central console.

Power MEC Controller – 1xxxEx

The Power MEC “E” versions support industry standard TCP/IP networks through a direct connection to 10/100 BaseT for BLN communications.

Page 2 of 8

Power MEC Controller – 12xxF and 13xxF

The Power MEC “F” version adds three connections to the Floor Level Network (FLN), for a total of 96 devices.

Power MEC Controller – 12xxL and 13xxL

The Power MEC “L” version adds LonWorks compatibility. It is equipped with a Neuron

Microprocessor and FTT-10A Transceiver. Instead of three connections to the APOGEE P1 Floor Level

Network, it has a single connection for a LonWorks network.

The “L” versions have a LonWorks network database server embedded. This database maintains a dynamic, real-time representation of the LonWorks network including connections/bindings, node status, and configuration parameters values.

The Power MEC consists of the following three major components:

• Input/Output Point Board

The input/output point board contains 32 points that perform A/D or D/A conversion, signal processing, point command output and communication with the controller board. The terminal blocks are removable for easy termination of field wiring. The analog input points are selectable to be 0-10V, 4-20mA, 1K RTD or optional 100K Thermistor. The analog output points are also selectable to be either 0-10V or 4-20mA. The digital inputs are dry contact, with four being pulse accumulator inputs. The digital outputs support

110/220V Form C rated relays.

• Power Supply

The power supply provides regulated power to the input/output point board and active sensors. The power supply is internal to the Power MEC housing, simplifying installation and troubleshooting.

The power supply works with the controller board to ensure smooth power up and down sequences for the equipment controlled by the I/O point board and analog and digital point blocks, even through brownout conditions.

Siemens Building Technologies, Inc.

Status LEDs indicate 24 Vac supplied from the power supply and 24 Vdc supplied to the input/output point board.

• Controller Board

The controller board is a microprocessor-based multitasking platform for program execution and communications with the I/O point board and with other Power MECs and field panels over the BLN.

The 12xx and 13xx controllers can also support analog or digital point expansion modules, which provide for point expansion capability to match the application requirements. The controller board scans field data, optimizes control parameters and manages operator requests for data.

An RS-232 operator terminal port with a quick connect phone jack (RJ-11) is included with each controller board for operator devices such as a Local

User Interface (LUI), simple CRT terminal, laptop PC, or printer. In addition, the MEC 13xx controller supports an RS-232 quick connect phone jack (RJ-45) for use with a phone modem for APOGEE Autodial stand-alone network capability.

The 12xxF and 13xxF controllers support 3 FLN trunks for communications with a total of 96 FLN devices.

The program and database information stored in the

Power MEC RAM memory is battery-backed. This eliminates the need for time-consuming program and database re-entry in the event of an extended power failure. When battery replacement is necessary, the controller board illuminates a “battery low” status

LED and can send an alarm message to selected printers or terminals.

The firmware including the operating system is stored in non-volatile flash ROM memory. Flash ROM is easily upgradeable at the job site. This provides for ease of upgrade, as new firmware updates are made available.

Brownout protection and power recovery circuitry protect the controller board from power fluctuations.

Enclosure Assemblies

The enclosure assembly houses both electronic and pneumatic components. The locking enclosure includes a perforated panel for mounting of the


Power MEC, Point Expansion Module and other electronic or pneumatic components. The enclosure is available in two sizes to allow the enclosure to match the requirements of the installation:

• Small - to house a controller or two point expansion modules

• Large - to house a controller and two point expansion modules or four point expansion modules

The enclosures are constructed of metal to accommodate secure conduit fittings and protect components against electrical transients. The enclosure allows space for easy wire routing and terminations.

Figure 3. Two sizes of Power Modular Equipment Controller enclosures.

Service Box

Two optional service boxes are available for mounting in the enclosure. One service box provides step down power from 115V to 24V, two Class 2 24 Vac power terminations (100 VA for Power MEC and Point

Expansion Modules, and 60 VA for actuators), and two un-switched 115 Vac outlets to power accessory devices such as modems and Portable Operator’s

Terminals. A second service box provides step down power from 230V to 24V and Class 2 24 Vac power terminations.

Figure 4. Power Modular Equipment Controller service box.

Analog and Digital Point Expansion Modules

In addition to the points on the input/output board, the 12xx and 13xx Power MECs support analog and digital Point Expansion Modules. The controller can support a maximum of any combination of eight modules. They can be mounted next to or remote from the controller depending upon the job requirements. The total length of the wiring run for

Point Expansion Modules is a maximum of 200 feet

(61 meters) on the MEC expansion bus. Point

Expansion Modules are also compatible with the

APOGEE P1 FLN.

Point Expansion Module details are:

• Analog Point Expansion Module – 4AI, 4AO

• Analog Point Expansion Module – 8AI

• Digital Point Expansion Module – 4DI, 4DO

• Digital Point Expansion Module – 8DI, 4DO

The analog input points are user selectable to be 0-

10V, 4-20mA, 1K RTD or optional 100K Thermistor input. The analog output points are also user configurable to be 0-10V or 0-20ma.

The digital inputs are dry contact with four of the inputs being pulse accumulator points. The relayed digital output points support 110/220V Form C relays.

Modular Equipment Control with Application

Flexibility

The Power MECs are high performance controllers with complete flexibility to allow the owner to customize each controller with the exact program for the application. In addition, each controller can be sized to meet the hardware requirements for the application.

The control program for each panel is customized to exactly match the application. Proven Powers

Process Control Language (PPCL), a BASIC type programming language provides direct digital control and energy management sequences to control equipment precisely and optimize energy usage.

In a stand-alone configuration, the MEC 13xx controller can fulfill all requirements of a Building

Management System (BMS) supervisory system; managing operation schedules, alarms and dialing out to other building systems, printers and pagers.

Global Information Access

Each Power MEC is equipped with one RS-232 operator terminal port. This port supports the connection of a Local User Interface (LUI), simple

CRT terminal, laptop PC, or printer. Devices connected to the terminal port gain global information access. The MEC 13xx supports a second RS-232 port for use with a modem.

Multiple Operator Access

Multiple operators can access the network simultaneously. Multiple operator access ensures that alarms are reported to an alarm printer while an operator accesses information from a local terminal.

When using the Ethernet BLN option, multiple


operators may also access the controller through concurrent Telnet sessions and/or local operator terminal ports.

Menu Prompted, English Language Operator

Interface

The Power MEC has a simple, yet powerful menu driven English Language Operator Interface that provides, among other things:

• Point monitoring and display,

• Point commanding,

• Historical trend collection and display for multiple points,

• Event scheduling,

• Program editing and modification via Powers

Process Control Language (PPCL),

• Alarm reporting and acknowledgment, and

• Continual display of dynamic information.

Built-in Direct Digital Control Routines

The Power MEC provides stand-alone Direct Digital

Control (DDC) to deliver precise HVAC control and comprehensive information about system operation.

The controller receives information from sensors in the building, processes the information, and directly controls the equipment. The following functions are available:

• Closed Loop Proportional, Integral and Derivative

(PID) control,

• Advanced loop tuning algorithm for (PID) parameters,

• Logical sequencing,

• Alarm detection and reporting, and

• Reset schedules.

Built-in Energy Management Applications

The following applications are programmed in the

Power MEC and require simple parameter input for implementation:

• Peak demand limiting,

• Start-Stop time optimization,

• Equipment scheduling, optimization and sequencing,

• Temperature compensated duty cycling,

• Economizer control,

• Night setback control,

• Automatic Daylight Savings Time switchover,

• Temporary schedule override,

• Holiday scheduling,

• Calendar-based scheduling, and

• Event scheduling.
