INSTALLATION

With the Excel 50, two different types of input/output ter­minals can be used: Screw terminal blocks for direct wiring
and Phoenix terminal blocks for remote wiring within the
same cabinet.

The installation procedures for the two types are different.
For proper installation, follow these instructions:

1. Read the complete chapter "Installation" carefully.

2. Depending on which terminal block type you have

chosen:

— Follow the instructions from the chapter "Screw

Terminal Block Installation Procedure".

or

— Follow the instructions from the chapter "Phoenix

Terminal Block Installation Procedure".

Fig. 16. Wiring options.

The two screw terminal blocks are attached directly to the
controller housing.

The Phoenix terminal blocks are connected to the controller
via flat strip cables. The use of Phoenix terminal blocks to­gether with the flat strip cables will reduce the installation
effort as well as wiring mistakes.

IMPORTANT

The numbering of the Phoenix terminals differs com­pletely from the screw terminal numbering. Using
screw terminal blocks will be the more common
solution. Therefore, in the following connection
examples, only the connections for screw terminal
blocks are shown. Refer to Table 4 when using
Phoenix terminal blocks.

Cabling

Cable Routing

All signal (input/output, low voltage) cables are communi­cation circuits in accordance with VDE 0100, VDE 0800 and
local regulations and should therefore be routed separately
from line voltage.

Table 5. Minimum Distances to Line Voltage.

Cable Type Minimum Distance

unshielded cable 4 in. (100 mm)

shielded cable 3/8 in. (10 mm)

IMPORTANT

Avoid joining sensor cables.

Shielding

Fig. 21. Sensor shielding.

Shielding of sensor and actuator cables with low protective
voltages is not necessary if the general guidelines on cable
routing are observed (see "Cable Routing", page 13). If these
guidelines cannot be observed, shielded cable must always
be used. The shielded cable must be grounded as is shown
in Fig. 21.

IMPORTANT

Shielding of I/O cables that are connected to
peripherals such as sensors and actuators must be
grounded at the control cabinet side only in order to
avoid ground loops.

All Honeywell actuators are RFI suppressed in accordance
with VDE 0871/B and VDE 0875/N.

Lightning Protection

Please check with your local Honeywell representative for
information on lightning protection.

Analog Inputs

Technical Description

The analog inputs convert data from passive sensors and
active sensors with voltage output. The analog inputs can be
used as current inputs for active sensors, but then an ex­ternal resistor parallel to the sensor is necessary. It is also
possible to feed digital signals to the analog inputs.

Technical Specification

Number:

Eight analog inputs

Types of input signals:

NTC 20k ohms

0 to +10 V (max. +11 V)

0 (4) to 20 mA (with an external resistor of 499 ohms
±0.25% [see Fig. 24])

Each input is switched automatically via software either as
input for NTC 20k ohms (high impedance) or voltage source
0 to +10V (max. +11V, low impedance).

NTC 20k ohms:

Range -58 °F to +302 °F (-50 °C to
+150 °C)

Voltage source:

Range 0 to 10 V

IMPORTANT

The analog inputs are protected against short circuit
and overvoltage up to 24 Vac and 40 Vdc. If any
input is sourced with more than 40 Vdc or negative
voltage, the other inputs will be influenced. This
could result in wrong values.

Fig. 25. Analog inputs used as digital inputs.

For normally open contacts, a digital signal must be switched
via the changeover contact of an additional relay.

Unconnected analog inputs have a default voltage of 8.5 V.
This is interpreted by the controller as a logical 1. This means
that, in general, no external relay is needed for normally open
contacts.

IMPORTANT

The relay contact must be suitable for switching low
voltage. For long cable distances, the analog input
signal may be sensitive to interference. In this case,
an external relay may also be used for normally
closed contacts.

Digital Inputs

Technical Description

Fig. 27. Input switching voltages.

The digital inputs signals can be DC voltage signals. If an
input voltage is higher than 5 V, the digital signal switches to
logic "1" status. With a hysteresis of 2.5 V, the input signal
must fall below 2.5 V before the digital status switches to
logic "0".

Three out of four digital inputs can be used as totalizers.

Beginning with V2.04.00 firmware, the online point attribute
Normally Open / Normally Closed (NO/NC) defines the
relation between the physical state (open/closed) and its
logical status. See Table 8.

Technical Specification

Number:

4 digital inputs

Type of signals:

DC signal max. 24 Vdc

Input resistance:

10k ohms

IMPORTANT

The digital inputs are protected against short circuit
and overvoltage up to 24 Vac and 40 Vdc.

Parameter requirements:

If the digital inputs are used for normal digital or analog
signals, the signals have to meet the static and dynamic
requirements stated in Table 8 and Table 9.

If three out of four digital inputs are used as totalizers, the
signals at the totalizer inputs have to fulfill the static and
dynamic requirements stated in Table 8 and Table 10 while
the signal at the fourth input has to meet only the static re­quirements of Table 8.

Analog Inputs

Technical Description

Analog outputs can be used, for example, to operate valve or
damper actuators. The characteristic curves for these
actuators can be defined via MMI (see Excel 50 User Guide).

Each analog output can also be used as a digital output.

Technical Specification

Number:

Four analog outputs

Analog output details:

Voltage 0 to 10 V, max. 11 V

Current max. 1 mA

Resolution 8-Bit

Min. step: 0.043 mV
Accuracy ±100 mV ±1 digit

Relay Modules

The relay modules facilitate the control of peripheral devices
with high load via the analog outputs of the controller. The
connection examples (for the relay modules MCD 3 and
MCE 3) are shown here.

IMPORTANT

The external supply of the relay modules must be
24 Vac, the same as of the supply of the controllers.

The analog outputs are protected against
overvoltage up to 24 Vac and 35 Vdc.

Supply:

Several relay modules can be connected in series via the
bridged terminal pair:

24 Vac: Terminals 11/12 of the relay

24 Vac (-): Terminals 13 to 16 of the relay

Digital Outputs

Technical Description

The digital outputs are switched by a triac that can be
connected directly to an external relay.

Technical Specification

Number:

Six digital outputs

Output stages:

Low signal 0 V

High signal 24 Vac

Type Close, only

Load:

Per output min. 0.01 A

max. 0.8 A

Total max. 2.4 A
Cos ϕ 0.5 to 1

IMPORTANT

The digital outputs are protected against short
circuit current via internal fuse, but they are not
protected against overload. All digital outputs are
protected via one fuse, only; if any digital output is
short-circuited, the fuse will be blown and will
interrupt the main power. In that case, the con­troller does not work. If the CPU is running into the
WATCHDOG caused by a software or hardware
error, all digital outputs will be set to low signal,
which means all digital outputs are inactive.

Beginning with V2.04.00 firmware, the online point attribute
Normally Open / Normally Closed (NO/NC) defines the
relation between the physical state (relay on/off) and its
logical status. See Table 11.

C-Bus Connection Procedure

1. Choose a suitable C-Bus cable from Table 18.

IMPORTANT

Make sure that all bus devices connected to the
same C-Bus are set to the same baud rate otherwise
proper communication cannot be ensured.

2. Set the DIP switch according to Table 17.

IMPORTANT

The C-Bus must be connected through the individual
controllers (open ring). Star connection is not per­mitted because uncontrollable line reflections could
occur.

3. Connect the cable shield to C-Bus terminal 4 (Fig. 45).

4. Connect the C+ cable to C-Bus terminal 5 (Fig. 45).

5. Connect the C- cable to C-Bus terminal 6 (Fig. 45).

6. If the maximum C-Bus length for the chosen cable

(Table 18) is exceeded:

— Use repeaters to extend to the maximum C-Bus

length (see section "C-Bus Extension by Using
Repeaters").

It may take up to two minutes to re-initialize the bus when
adding or removing a controller to/from the C-Bus. During
this time, communication on the C-Bus is lost.

LONWORKS Network Interface

Excel 50 Controllers may be equipped with an application
module (see Table 15) containing an FTT-10A Free Topology
Twisted Pair Transceiver which allows communication with
other device on a L

communicate at 78 Kbaud and provide transformer isolation
so that the bus wiring does not have a polarity; that is, it is
not important which of the two bus terminals are connected
to each wire of the twisted pair.

FTT devices can be wired in daisy chain, star, loop or any
combination thereof as long as the maximum wire length re­quirements given below are met. The recommended con­figuration is a daisy chain with two bus terminations. This
layout allows for maximum bus length, and its simple struc­ture presents the least number of possible problems, par­ticularly when adding on to an existing bus.

NOTE: A doubly-terminated bus may have stubs of up to

10 ft (3 m) from the bus to each node.

NOTES:

The cable types listed above are as recommended by

core, nonshielded cable. Belden part numbers are
9H2201504 (plenum) and 9D220150 (non-plenum).

The FTT specification includes two components that must be
met for proper system operation. The distance from each
transceiver to all other transceivers and to the termination
must not exceed the maximum node-to-node distance. If
multiple paths exists, the maximum total wire length is the
total amount of wire used.

IMPORTANT

Do not use different wire types or gauges on the
same L

ONWORKS network segment. The step change

in line impedance characteristics would cause
unpredictable reflections on the network.

NOTE: In the event that the limit on the total wire length is

exceeded, then FTT physical layer repeaters
(FTT 10A) can be added to interconnect segments
and increase the overall length by an amount equal
to the original specification for that cable type and
bus type for each repeater used. For example,
adding repeaters for a doubly-terminated bus using
JY (St) Y 2x2x0.8 cable increases the maximum
length 3,000 ft (900 m) for each repeater.

LONWORKS Bus Termination

One or two Termination Modules, part no. 209541B, are re­quired for a L

ONWORKS Bus with FTT devices on it, de-

pending upon the configuration. The maximum lengths des­cribed in the previous section must be adhered to for either a

LONWORKS Service LED Diagnostics

The LONWORKS service LED is used to diagnose the state of
the Excel 50 controller. In general:

— The controller is applicationless if the LED illuminates

continuously*

— The controller has an application but it is not configured

if the LED is blinking

— The controller is running normally if L2 is off

The L

ONWORKS service LED is located on the application

module (see Fig. 45).

Pushing the L

ONWORKS service button will force a new

commissioning of the Excel 50. While commissioning, LED
L2 continuously illuminates red for less than 1 minute and
afterwards return to the normal state (L2 = OFF).

A more detailed diagnosis can be carried out by observing
the duration of the ON and OFF states of the service LED in
connection with power ON / OFF. The following figure
illustrates the different service LED behaviors. These are the
most common behaviors, but others are possible since the
state of the service LED is under firmware control and can be
affected both by hardware and software anomalies.

Fig. 48. LONWORKS Service LED behaviors.

The following table describes each of the behaviors shown in
the previous figure under different contexts. Again, this list is
not exhaustive and therefore does not provide explanations
for every possible service LED behavior.

Table 22. L

ONWORKS Service LED behavior descriptions.

Behavior Context Likely Explanation

1 Power-up of the node Bad node hardware.

2 Power-up of the node Bad node hardware.

3 Power-up / Reset of the node The controller is applicationless. May be caused by the Neuron chip firmware

when a mismatch occurs on application checksums. This behavior is normal if
the application was exported to come up applicationless.

4 Anytime Possible corrupt EEPROM. For a Neuron 3150 Chip-based node, use a newly

programmed PROM, or EEBLANK and follow bring-up procedure.

5 Anytime The controller is unconfigured.

6 First power-up, Applicationless

firmware state exported

The OFF duration is approximately 1 second. Service LED should then turn
ON and stay on indicating an applicationless state.

6 First power-up, Unconfigured

firmware state exported

The OFF duration is 1-15 seconds depending on the application size and
system clock. Service LED should then begin flashing as in behavior 5,
indicating an unconfigured state.

6 First power-up, Configured

firmware state exported

The OFF duration is indefinite (1-15 seconds to load internal EEPROM; stays
OFF indicating configured state.) The controller is configured and running
normally.

7 Anytime The controller is configured and running normally.

Flash-EPROM versions of the Excel 50 Controller.

NOTE: Remote communication via modem or ISDN terminal

adapter requires firmware version 2.01.00 or higher.

SERIAL PORT

EXCEL 50 (REAR VIEW)

Fig. 51. Modem connection.

The serial port of the Excel 50 controller accepts a standard
modem cable with a female 9-pin connector. Use the cable
that is supplied with the modem/ISDN terminal adapter.

The communication speed is 9.6 Kbaud by default but can be
set as high as 38.4 Kbaud.

For more details, see section "Remote Communication".

Changing Between MMI and Modem Connection

The XL50 will detect when an MMI or modem/ISDN terminal
adapter is connected and will adjust the communication
speed automatically according to the preset values. This
automatic detection can take up to 5 seconds.

REMOTE COMMUNICATIONS

Firmware version number 2.01.00 or later supports the
direct connection of modems or ISDN terminal adapters for
communications to up to three remote XBS building super­visors.

NOTE: XBSi building supervisors are not supported for

remote communication.

NOTE: Communication via ISDN is applicable only for

Europe.

Modem Requirements

• Modem must support Hayes compatible command set

(not V150 or V151 = Microsoft command set)

• Modem must support alpha-numeric return codes

• Modem must follow serial baud rate of the CPU

• Modem must support auto-bauding (baud rate fall-back)

• W hen carrier detect (connect) is reported, the carrier

must be on simultaneously at both modems (on CPU
side and on XBS side) ⇒ use same modem

• After a switch-on of the DTR line by the CPU or XBS,

the modem must accept a dial command after 3
seconds

• Modem must answer AT commands in less than 3

seconds

No Set-up for Standard Modem Behavior

If no special modem behavior is required, there is no need
to set up or initialize the modem/ISDN terminal adapter.
The Excel 50 Controller will automatically detect the device
(MMI or modem) attached to the serial port and set the
appropriate communication speed. The controller will also
automatically adapt to alphanumeric return codes used by
the modem. This automatic detection and adjustment can
take up to 5 seconds.

NOTE: It is highly recommended to use a state-of-the-art

modem and leave it in its factory setting.

Automatic Baudrate Synchronization

The default communication speed between the Excel 50
Controller and the local modem/ISDN terminal adapter is

9.6 Kbaud.

The communication speed between the Excel 50 and XBS
modems/ISDN terminal adapters is automatically syn­chronized by the two devices to the highest speed that
both of the devices are capable of. This feature is called
autobauding and is provided by all state-of-the-art modems
/ ISDN terminal adapters when left in their factory default
settings.

The communication speed between the XBS and its
modem / ISDN terminal adapter is part of the modem set­up at the XBS.

Auto / Manual Answer Detection

The Excel 50 Controller will automatically detect whether
the modem/ISDN terminal adapter is initialized in auto­answer or manual answer mode, and it will set the modem
to the manual answer mode (S0=0).

Resetting the Modem

For those cases where it is not clear if the modem to be
used is in its factory setting, the modem can be reset to its
factory setting by using the RESET MODEM command in
the Start-up sequence or through the HW Config. part of
the System Info. sequence on the MMI. This will allow a
quick and easy modem reset without having to run the
modem set-up software or the Windows™ terminal
program.

The RESET MODEM command causes the following com­mands to be sent to the modem:

1. ATZ: Executes hardware reset on modem

2. AT&FX3&W: Resets modem to factory configuration

settings, configures the modem to not wait for the
public phone system dial tone, and writes this to non­volatile memory.

Set-up for Special Modem Behavior

If special modem/ISDN terminal adapter behavior is re­quired, the communication device should be set up
according to the instructions provided with it. This typically
involves running a set-up program on a computer with the
device connected to the computer serial port or using the
Windows™ terminal program.

Set-up for In-house Telephone Systems

A common case of special modem behavior is when the
modem is connected to an in-house telephone network re­quiring a prefix to be dialed before the destination number
to provide access to the public telephone network. There
are two important aspects of the special initialization of the
modem to consider:

1. Do not wait for the public network dial tone. Typically,
the init command ATX3 will trigger the modem to dial
without waiting for a public network dial tone. Save
this modem set-up in the modem EEPROM with the
command AT&W. Check the modem handbook to
verify the correct commands. Note that these
commands are executed automatically with the
RESET MODEM command in the Excel 50 Controller
Start-up Sequence.

2. Add the prefix required for accessing the public tele­phone network to the destination telephone number.
Depending on the in-house telephone system, a
certain prefix may have to be added to the
destination number in the XBS system
configuration/site definition screen before sending
the set-up to the remote Excel 50 controller.

Set-up for Limited Communication Speed

The communication speed of the modem can be fixed to a
lower rate in case of data transmission errors due to tele­phone line limitations. See section "Start-up Sequence" or
see the Excel 50 User Guide, EN2B-137, for the procedure
for fixing the baud rate.

Troubleshooting

In case of any problems the handbook of the modem or
ISDN terminal adapter must be consulted.

TCP/IP Dial-Up via TCP/IP Modem XM500

The Honeywell TCP/IP modem XM500 allows use of a
TCP/IP network (e.g. Ethernet LAN/WAN networks) to
achieve a dial-up connection between an XBS building
supervisor and an Excel 50 controller. The set-up is
identical to that of a telephone modem connection, with the
exception of the additional need for definition of the
Ethernet address.

GSM COMMUNICATION (EUROPE, ONLY)

For communication via the Global System for Mobile com­munications (GSM), a Siemens M20 Terminal (cellular
engine) is required and must be connected directly to the
serial port of the Excel 50 controller. The M20T translates the
Excel CPU data received in transparent mode into the GSM
standard. The M20T behaves like a Hayes-compatible
modem connected to the Excel controller serial port, and it
then transmits via GSM like a cellular (mobile) phone.

NOTE: Communication via GSM requires firmware version

V2.3.0 or higher.

IMPORTANT

With the M20T, data communication is possible only
in 900 MHz GSM networks. GSM networks operating
at 1800 MHz or 1900 MHz are not supported.

The maximum communication speed is determined by the
current GSM standard, which is 9.6 Kbaud. Due to a special
transmission mechanism, the effective communication
throughput is lower than 9.6 Kbaud – however this will be
noticeable only when high data volumes are transmitted, e.g.
when application download is performed.

M20T Safety Precautions

CAUTION

Use of the M20 Terminal on-board aircraft is for­bidden. Use of a Cellular Engine in an aircraft, such
as for the purpose of wireless connection of an
aircraft-based HVAC system to an XBS central, can
endanger navigation, it interferes with the cellular net­work, and it is illegal. Failure to comply with this pro­hibition may lead to temporary suspension or per­manent cancellation of Cellular Engine services for
the person who disregards this prohibition and/or to
legal action against said person.

CAUTION

Users are advised to NOT use the M20T in auto­motive service stations.

Users are reminded of the necessity of complying
with restrictions regarding the use of radio devices in
fuel depots, chemical plants, and locations where ex­plosives are detonated.

Additional precautions are as follows:

• When receiving calls on a public highway, such as

a cooling control system of a refrigeration truck
being called by an XBS central, the M20T is not
permitted to use "warning" devices which permit
the vehicle’s horn to sound or the lights to flash.

• Drivers are advised not to use the handheld micro-

phone or the telephone handset while their vehicle
is in motion, except in emergencies. Use the
hands-free facility to speak only if it does not divert
your attention from the traffic.

• Operation of the M20T can disrupt the operability

of inadequately protected medical devices. Please
address all questions to a doctor or the manu­facturer of the medical device.

• The M20 Terminal shall not be used within wet

environment, such as in public baths.

• If your M20 Terminal, your SIM card, or both are

lost, notify your network operator immediately in
order to avoid misuse.

Required Third-Party Equipment

The Siemens M20 Terminal (shown below) is required for
GSM communication. In addition, a 3V Mini SIM card with
personal identification number (PIN) is required for the M20T.
The Mini SIM card, supplied by the GSM Network Provider,
must be released for data communication at 9.6 Kbaud. A
separate telephone number is required for data communi­cation with the same SIM card (one telephone number for
voice communications and one for data).

GSM Antenna Requirements

All major suppliers of GSM antennas can supply GSM900
Antennas with FME plugs to connect with the M20 Terminal
for a variety of applications. Some antenna examples are
shown below. The antenna must satisfy the following
electrical requirements:

Antenna electrical requirements:

Frequency TX 890-915 MHz
Frequency RX 935-960 MHz
Impedance 50 ohms
VSWR TX: max. 1.7:1 installed
VSWR RX: max. 1.9:1 installed
Gain > 1.5 dB referenced to λ/2

dipole
3dB width of cone vertical: 80°

horizontal: 360°

Maximum power: 1 W (cw), 2 W peak; at

ambient temperature of 55 °C

Depending on the application and the RF field at the local
site, the GSM antenna may be mounted directly or via cable.
The maximum antenna cable length is 8.0 m (including 20
cm M20 Terminal-cable)

NOTE: The maximum number of push/pull cycles shall not

exceed 100.

The antenna interface connector of the M20 unit is an FME
connector (of type SMR nano (male)). Hence, the connector
on the GSM antenna or antenna cable has to be of type SMR
nano (female, or use a double female connector in between).

Fig. 56. Window Patch Antenna, 2 DBi.

GSM Antenna Installation

The maximum antenna cable length is 8.0 m (including the
20-cm M20 Terminal cable). Use a cable that is specified by
the supplier of the GSM antenna. Improper cables with re­sistances that are too high will reduce the antenna's ampli­fication.

• Ideally you should know in which direction the next GSM

station is located in order to position of the antenna
accordingly.

• The easiest way to check the signal quality is to operate a

cellular (mobile) phone at the very place where you want
to place the antenna.

— The cellular phone must operate in the same GSM

network as the M20T.

— Drop-outs in voice communication indicate that the

reception is too weak. The data communication will
never work where you have drop-outs in voice com­munication with the cellular phone. The preferred
way is to set-up the M20T on a terminal program and

check the reception with the SIEMENS AT com­mands – see the M20T handbook.

— An alternative way to verify the signal quality is to

use the terminal program on the CD supplied with
the M20T. You will find a special button on it that
allows checking on the signal quality.

• Dipole antennas (e.g. antennas with a magnetic foot) must

sit on metal ground to achieve the specified amplification.
The larger the metal ground, the better.

• The antenna must be mounted vertically, NOT horizontal-

ly.

• Avoid barriers for the antenna signal. Ideally, within a

range of approximately 3 meters, there should not be any
vertical barriers that would block the antenna signal, such
as doors, PCs, cupboards, etc.

• Select the most suitable antenna. Location and mounting

limitations may require that special antennas be used,
such as antennas with higher amplification or directional
antennas.

• Avoid loose contacts. All connections from the M20T to

the antenna must be tight.

• Increase the distance between the antenna and Excel

CPU if you experience electromagnetic interference of the
antenna signal to the CPU. An indication of this might be
that the functioning of the MMI of the CPU is disturbed or
that the outputs behave abnormally.

M20 Terminal Set-up

Prior to beginning the set-up, get the M20T manual (or CD­ROM, if it was delivered with one). Everything is described in
it and you will need it.

IMPORTANT

It is absolutely mandatory to use a serial data line
monitor for the set-up of the M20T. Without such a
device being connected between the serial port of
the PC and the M20T, you will get no information on
the set-up process.

1. Insert the SIM card into the M20T.

2. Connect the serial cable to the M20T and a PC or

laptop.

3. Connect the antenna cable and antenna to the M20T
connector.

4. Start a terminal program, e.g., Windows™
HyperTerminal

5. Connect the power supply to the M20 Terminal and
plug into mains.
The M20T LED will be blinking now.

6. Set terminal program to 19200 baud.

7. Verify the correct operation of the M20T serial interface

by entering: AT.
The M20T will respond: OK.

8. Change the M20T’s baud rate from 19200 (factory
default) to 9600: AT+IPR=9600.

9. Set terminal program back to 9600 baud.

10. Command the M20T to cut the line whenever the DTR

signal is dropped (OFF) or toggled ON/OFF: AT&D2

11. Store setting in nonvolatile memory: AT&W.

EXCEL 50 INSTALLATION INSTRUCTIONS

EN1B-0101 32

12. You may now enter the PIN number or let the Excel
CPU do this. If you want to enter the PIN number now,
enter the PIN with the command AT+CPIN=”xxxx”,
where xxxx represents the PIN number.

NOTE: Regarding the PIN entry, the M20T shows the same

behavior as a regular cellular phone, as it uses the
same type of SIM card. This means, for example,
that after 3 false PIN inputs, the SIM card will lock
and need to be released via the “PUK” Personal
Unlocking Key (Master PIN).

Repeated input of the wrong “PUK” (more than 2
false inputs) will destroy the SIM card irrevocably.

13. Once the M20 has accepted the PIN it will log into the
GSM net.
The terminal window will show “OK”.
The M20T LED will be on continuously.

14. Disconnect the serial cable from the PC/laptop and
connect it to the Excel CPU.

15. Verify that the M20T dials out on the telephone number
for data communication, otherwise its call will not be
recognized by the XBS. The M20T can be forced to do
so by adding the letter <i> to the telephone number,
e.g. <ATDi1234567891234>

NOTE: As soon as the PIN is entered into the Excel con-

troller, the following mechanisms will take place
automatically:

— Cyclical check (once per minute) for existence

of the PIN number in the M20 (AT+CPIN?)

— Sending of PIN number to M20T, if it has lost it.

This guarantees that communication will re­sume automatically after exchange of the SIM
card or after power to the M20T has been lost.

Deletion of the PIN number or resetting the controller
will stop the above mechanisms.

Verification of the PIN

You can verify the PIN without connecting a terminal program
by following these steps:

1. Connect the XI582AH MMI.

2. Enter PIN.

3. Disconnect the XI582AH MMI.

4. Connect the M20T.

5. Reconnect the XI582AH MMI.

6. View the “PIN” field.

7. If it shows “0”, the PIN was wrong.

8. If it shows “PIN”, the PIN was correct.

Rem. Trend Buf.
104 Entries>BACK

This screen is used to increase the size of the adjustable re­mote trend buffer by reducing the application memory size.
The number of entries (trend samples) that can be stored in
the buffer for Remote Building Central A is determined by a
calculation by the controller based upon the Application
Memory Size entered in this screen (remote trend buffer =
(128 Kbytes minus the Application Memory Size) * 1024
bytes / 47 bytes). The default for the Application Memory
Size is 128; the minimum Application Memory Size is 38
Kbytes. The default number of Remote Trend Buffer Entries
is 104.

If a new value for Appl. Mem. Size has not been entered, the
cursor is at NEXT. Confirm with ENTER and continue to the
next screen.

To increase the size of the buffer, use the arrow keys to
select the digits for ‘Appl. Mem. Size’ and use the ‘+’ and '–'
keys to enter a new value. Then select RESTART and con­firm with ENTER. The controller will reset again, and the
‘Start-up’ sequence starts again from the beginning.

• AO0201: Analog output, board 2, output 1

• DI0301: Digital input, board 3, input 1

• DO0401: Digital output, board 4, output 1

NOTE: The board numbers shown above are internal

references and are not relevant to the User. In Excel
50 Controllers the numbers are fixed for the I/O type,
i.e. analog inputs are always AI01, digital inputs are
always DI03, etc.

After generating the default addresses, the following screen
appears:

NOTE: Alarms are generated for changes of state/value on

inputs, which allows shorting and opening the inputs
at the switches and/or sensors and then checking
the alarm buffer to verify the wiring.

To view an alarm, move the cursor to select the default user
address from the list box using the arrow keys. Confirm with
ENTER. The following screen will appear:
