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. All circuits are power-limited.

Table 3. Min. distances to line voltage

cable type min. distance

unshielded cable 4 in. (100 mm)

shielded cable 3/8 in. (10 mm)

IMPORTANT

Avoid joining sensor cables.

EXCEL 50 INSTALLATION INSTRUCTIONS

Shielding

sensor

Fig. 16. 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 section "Cable Routing", page 13).
If these guidelines cannot be observed, shielded cable must
always be used. The shielded cable must be grounded as
shown in Fig. 16.

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; this is 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.

NOTE: Use Honeywell surge protectors or Honeywell-

approved third-party surge protectors.

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 (see also section
"Sensors and Transducers" on page 18).

Technical Specification

Number: Eight analog inputs
Types of input signals:

NTC 20 kΩ
0 to +10 V (max. +11 V)
0 (4) to 20 mA (with an external resistor of 499 Ω ±0.25%

[see Fig. 19])

Each input is switched automatically via software either as
input for NTC 20 kΩ (low impedance) or voltage source

0...+10V (max. +11 V, high impedance).

NTC 20kΩ: Range = -58 … +302 °F (-50 … +150 °C)
Voltage source: Range = 0...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. 20. 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. In the case of long cable distances, the

00000061

analog input signal may be sensitive to interference.
In this case, an external relay may also be used for
normally-closed contacts.

Fig. 23. Input switching voltages

The digital input 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.
With V2.04.00 and higher firmware, the online point attribute

"Normally Open / Normally Closed" (NO/NC) defines the
relation between the physical state (open/closed) and its

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
only a single fuse; if any digital output is short­circuited, 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 as
a result of 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

C-Bus Extension by Using Repeaters

The C-Bus length can be extended by using repeaters. Each
repeater extends the bus length by 4,000 ft (1,200 m).

For the US the repeater is available either with or without
housing. In Europe, only the version with housing is allowed.

C-Bus Connection Procedure

1. Choose a suitable C-Bus cable from Table 24.

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 23.

— Use repeaters to extend to the max. 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 21) 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. See also Fig. 35.

FTT devices can be wired in daisy chain, star, loop or any
combination thereof as long as the max. wire length re­quirements given below are met. The recommended con­figuration is a daisy chain with two bus terminations. This
layout allows for max. 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.

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 max. node-to-node distance. If multiple
paths exists, the max. total wire length is the total amount of
wire used.

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

exceeded, 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 max. length
3,000 ft (900 m) for each repeater.

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, if the LED is

blinking, it is not configured.
— The controller is running normally if L2 is OFF.

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.

ONWORKS Service LED behavior descriptions

The controller is applicationless. May be caused by the Neuron chip firmware
when a mismatch occurs on application checksums.

Possible corrupt EEPROM. Use a newly programmed PROM, or EEBLANK and
follow bring-up procedure.

The OFF duration is approx. 1 second. Service LED should then turn ON and
stay ON, indicating an applicationless state. The controller is defective – return
to factory.

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.

The OFF duration is indefinite (1...15 seconds to load internal EEPROM; stays

Modem or ISDN Terminal Adapter Connections

For remote communications, a modem or ISDN terminal
adapter can be connected directly to the serial port of all
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.

Fig. 40. Excel 50, modem connection (rear view)

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.

EN1B-0101GE51 R0909G

EXCEL 50 INSTALLATION INSTRUCTIONS

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)

• When 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, set the appropriate
communication speed, and 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 set-up at the
XBS.

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 Start­Up 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.

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".

Auto / Manual Answer Detection

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

EN1B-0101GE51 R0909G 30

Troubleshooting

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

A “Frequently Asked Questions and Troubleshooting”
document is available via the Honeywell Technical Assistance
Center (TAC) or, for Honeywell employees, on the HIVE.

shown above, default user addresses are generated following
the following pattern:

• AI0101: Analog input, board 1, input 1

• 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:

!Default Points
!Alarm History

EXCEL 50 INSTALLATION INSTRUCTIONS

Select
— 'Default Points' to display I/O points for checking values

and manually setting outputs for testing.

— 'Alarm History' to display current alarms. This feature

allows the system to be checked out by a single person
opening and closing inputs and then later reading the
alarm buffer to see if they were detected by the con-

troller.
Confirm with ENTER.
If ‘Default Points’ has been selected, the following screen will

be displayed showing all default user addresses and their
current values.

!<user addr.> <val>↑
!<user addr.> <val>1
!<user addr.> <val>
!<user addr.> <val>↓

To manually set outputs, move the cursor to select the output
point from the list box using the arrow keys. Confirm with
ENTER.

In the case of analog points, the following screen is displayed.

<user addr.>
STATE/VALUE:
!0.00%

Press ENTER to select the value. Change the value using the
'+' or '–' keys. Confirm with ENTER. In the case of digital
points, the following screen is displayed.

<user addr.>
STATE/VALUE:
!0 %

Press ENTER to select the value. Change the value/state
using the '+' or '–' keys. Confirm with ENTER.

Press CANCEL to return to the previous screen (list of user
addresses).

If ‘Alarm History’ has been selected, the following screen will
be displayed showing all points in alarm as well as any
system alarms (max. 100 entries):

!<user addr.> ↑
!<user addr.> 1
!<user addr.>
!<user addr.> ↓

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:

<date.> <time>
<user addr.>
<value>
<alarm text>

Press CANCEL to return to the previous screen.

IMPORTANT

Reset the controller after using the test options to
clear the alarm buffer.
