MINI DATA ALARM PROCESSOR II

The MINI-DAP II control panel is designed for Data Aire Ceiling systems with one or two cooling stages, one heating

stage and a humidifier. This microprocessor based control offers innovative features and “state of the art” technology.

Figure 1: Mini-Dap II Panel

Design Features

• Microprocessor based dual layer board

design

• 16 characters liquid crystal display (LCD)

• Panel mounted temperature and humidity

sensor are standard

• Nonvolatile memory storage for all

programmed settings and alarm history (5

latest alarms)

• Printed circuit board mounted audio alarm

• Five control outputs for fan, cooling stage 1,

cooling stage 2, heat, humidifier

• Five alarm inputs with three selectable

messages

• Optional plug-in remote alarm contact

Software Features

• Setpoint deviation control logic

• Selectable night setback and on/off

functions provide an economical control

solution

• Adjustable system reaction time (Adjustment

rate)

• All settings are programmed using menu

driven soft-touch keys

• Adjustable temperature and humidity

deadband

• °C to °F conversion

• Two level passwords for menus access

• Calibration offset for temperature and

humidity sensor

• Manual diagnostics for components

troubleshooting

REV 8/03 4

REV 8/03 5

Protective & Safety features

• Metal shell enclosure protects panel from

electromagnetic interference, environmental

contamination and handling damage.

• Protected 24 VAC power input:

- 1amp fuse for processor portion of the

PC board

- 5 amp fuse for relay outputs

- Metal Oxide Varistor (MOV) snubs the

transient voltage and protect the circuit

board from an excessive power.

• Opto-isolators for 24 VAC signal inputs

protect the processor from electrical noise of

contactors, compressors and motors, ect.

Conditions and Functions Displayed

• Current room temperature (°F or °C)

• Current room humidity (% RH)

* Alarm displays require additional components or sensors and programmable selections. Some

alarm messages are selected using one of three optional alarm menus.

** These alarms will be set-up at the factory as defaults on single or dual compressor unit.

Historical Data

• Maximum and minimum temperature and humidity since unit has been on.

• Last five alarms to occur.

Location Considerations

Locate the MINI-DAP II panel as follows:

• On a partitioning interior wall, and approximately 5ft (1.5 m) above the floor in a location of the best

average room temperature, room humidity and good air movement.

• Away from direct sunlight or radiant heat, outside walls or behind doors, air discharge grilles or

outside doors.

• Away from steam or water pipes, warm air stacks, unheated/uncooled areas, monitors or sources of

electrical interference.

CAUTION: Shock Hazard. Disconnect power before wiring connections are made

to prevent electrical shock or possible damage to the equipment.

Figure 2: Terminal identification and circuit board details.

Installation and Wiring

To install and wire the MINI-DAP II panel:

1. Use a Phillips screwdriver to loosen the side screws of the panel.

2. Remove the cover of the MINI-DAP II panel. Place the panel against the wall, mark the location of

three mounting holes. See figure 3.

3. Use plastic anchors and screws for mounting on drywall or plaster (recommended).

4. Connect one end of the factory provided cable to the unit terminal strip, refer to unit wiring diagram for

details. Use the color coded wires to designate the functions and terminal number. See figure 2.

5. Use color code to identify the wire function and connect the other end of the cable to MINI-DAP II

panel.

CAUTION: Equipment Damage Hazard. Before applying power, make all wiring connections and

check the connections. Short circuited or improperly connected wires may result in permanent damage to

the unit.

REV 8/03 7

Installing the Optional Remote Alarm Contact

1. Turn the Mini-Dap II off. Loosen the side screws and remove the panel cover.

2. Remove four screws that secure the 2nd layer board to the base board. See figure 4.

3. Unplug the 2nd layer board.

4. Plug the summary alarm contact board to CON4 plug on the base board. See figure 4.

5. Reinstall the 2nd layer board back to the base board.
