MD20 Master Display
Installation Guide
READ THIS INSTRUCTION SHEET AND THE SAFETY WARNINGS
CAREFULLY BEFORE INSTALLING AND SAVE IT FOR FUTURE USE
General Features
• The MD20 Master Display is the supervisory controller of the Facility
Explorer System. The MD20 Master Display monitors and interacts with
a network of heating, ventilating, air conditioning and/or refrigeration
(HVAC/R) controllers to form a complete building or equipment control
system and provides operating data to local and remote users and
operators via a number of different media options.
• The MD20 Master Display is freely programmable using the FX Tools
software package and the functions include centralized control and
management of distributed applications as well as the display and
communication features.
• It is suitable for use in normal non-hazardous and non-corrosive
environments.

Mounting
Figure 2:
Panel mounting
1. Fixing brackets and gasket provided with LP-KIT020-000C:
Panel Mount Kit for MD20.
Make a cut-out in the panel. Ensure that there is at least 50
mm of free space on all sides of the cut-out to allow for the
mounting and wiring of the MD20 Master Display. Remove
the screw terminals (if already installed) and install the
gasket on the Master Display. Insert the MD20 Master
Display into the cut-out and secure in place using the fixing
brackets. Check that the gasket is positioned correctly on
the outside face of the panel to prevent the ingress of dust
into the panel enclosure. Re-install the screw terminals.

Figure 3:
DIN rail mounting
1. Snap the controller onto the 35 mm DIN rail (1.38 inch).
2. To release the controller insert a screwdriver in Slots “A”
and pull out the retaining clip. Since the retaining clip is
spring-loaded, you can also remove the controller without a
screwdriver by carefully pushing the controller up against
the clip and then tilting the top forward to release the top lug
from the DIN rail. Reverse the procedure to install again.
• Keep all cables as short as possible and tie in position.
• Wiring terminations for binary inputs and binary outputs are made by
detachable connectors, which accept 1 x 1.5 mm2 / 16 AWG cable.
Terminations of the Supervisor Link. Expansion Bus and Local Link are
made via detachable connectors which accept 2 x 0.8 mm2 / 20 AWG
cable. The connectors are provided with the controller.
• Verify that the wiring has been correctly installed, and that voltage levels
are appropriate for the various input signals according to the application.
Installation

Electronic Circuit Isolation Diagram
All the inputs, outputs and the communication ports are isolated from the
24 VAC power supply and from the CPU, except for the RS232C ports to
the printer and modem.

Figure 11: Connections details for the Printer Port
Each model of the MD20 Master Display has a serial RS232 port for the
connection of a serial printer that uses continuous fan-fold paper.
(*) Serial Link cable (DB9 connectors) to be ordered separately from the
printer supplier.
Connections details for the RS232C-Modem
communication port
The RS232C - Modem Communication port allows the MD20 Master Display
to be connected to a Modem (Standard Land Line or GSM) or via direct
connection (NULL-Modem) to a PC.

Figure 14: Connection Details to use the RS232C port as an N2
Port for Firmware Downloading
1. Serial DB9 Commissioning Adapter
The RS232 Communication Port on the Master Display can be used for
downloading firmware wiring the FX Loader utility when an N2 Open port is
not available. This applies to the following models:
LP-MD20D00-000C / LP-MD20D02-000C / LP-MD20D03-000C /
LP-MD20D04-000C (see “Ordering Codes”).
In order to perform the download operation:
• Power off the MD20 Master Display.
• Add the Serial DB9 Commissioning Adaptor LP-KIT007-015C between
the null-modem cable and the PC.
• Power on the MD20 Master Display.
The RS232C port now responds as an N2 Port for download of firmware
from FX Loader utility.
Figure 15: Connection Details for N2 Open and N2 System 91
Devices on Local Link Bus
All models of the MD20 Master Display have the Local Link Bus that
supports controllers and devices with an N2 Open interface, including the
controllers of the Facility Explorer System, and the DX-9100 and TC-9100
Series of controllers with an N2 System 91 communication interface.
Controllers of the Facility Explorer System can be configured in the same
way as other devices to be monitored and controlled by the MD20 Master
Display. Alternatively up to eight Facility Explorer controllers can be more
closely integrated into a common control system by including them in a
Distributed Application in the MD20 Master Display.

Figure 16: Connection Details for I/O Expansion
(LP-XT/LP-XP Modules) on Local Link Bus
The MD20 Master Display supports up to four LP-XT Extension modules
with a variety of combinations of analog and binary, input and output points.
Data from these modules can be used for display or as additional inputs
and outputs for control routines in the MD20 Master Display or other
connected controllers.
Local Link Bus layout
• Maximum bus length before installing a repeater: 1,200 m / 4,000 feet.
• Install the RP-9100-810x to repeat and regenerate the RS-485 signal in
case more than 31 N2 Devices have to be connected on the same
N2 bus trunk and/or the N2 bus trunk length is more than 1,200 m.
• Install 220-ohm end-of-line resistors at each end of the Bus line when the
bus length is greater than 100 meters/330 feet. When the bus length is
less than 100 meters/330 feet insert only one 220 Ohm resistor at the
MD20 Master Display end only.
• The network cable must be laid along a low voltage cable path. It must
be placed at least at 30 cm from cables carrying high voltages or
currents (>230V or >30A). If strong interference fields are expected, the
cable must be located at the greatest distance possible from the source
and the use of RS485 signal repeaters is strongly advised.
Figure 17: Connection Details for N2 Open port Supervisory Link
Availiable only for LP-MD20D01-000C / LP-MD20D05-000C
(see “Ordering Codes”).
The N2 Open port allows the MD20 Master Display to be connected to an
N2 Open bus network through the RS485 standard or it can be used for
downloading and commissioning purposes.
Figure 18: Connection Details for LON port
Available only for LP-MD20D02-000C / LP-MD20D04-000C /
LP-MD20D05-000C (see “Ordering Codes”).
The LONWORKS® port allows the MD20 Master Display to be connected to
a LONWORKS® network and it is also used for downloading the application
file using MD Loader.
