MOUNTING

Control Unit Installation

The Excel 500 and 600 controllers have the same housing and can be installed two different ways:

— Installation inside a control panel (see page 8). — Installation through a control panel door (see page 10).

Fig. 1. Excel 500/600 panel door mounting

The Excel 500-XCL5010 can be mounted only on a DIN rail; control panel door installation is not possible.

Fig. 2. Excel 500-XCL5010 DIN rail mounting

Fig. 3. Up to five housings can be connected together

When housings are alongside one another, a minimum spacing of 1.5 in. (35 mm) should be taken into consideration to enable the hinged cover to be opened. The maximum spacing between housings is limited by tailor-made internal bus cables as shown in Fig. 3.

Excel 500/600 Internal Bus Wiring (not XCL5010)

Each housing has four plug-in module locations. The individual modules are connected by an internal bus in the housing.

Configurations comprising more than one housing must have the individual busses in the housings connected to one another.

Excel 500/600 Housing Layout (not XCL5010)

A controller comprises from one to a maximum of five housings. The housings may be fitted alongside one another or, one above the other. Any combination is possible.

EN1R-1047GE51 R0902 6

Fig. 4. Excel 500/600 bus wiring

The connection is made via tailor-made ribbon cables. Two different types are available:

— Type XW568 3 in. (80 mm) long (for housings alongside

one another)

EXCEL 500/600 INSTALLATION INSTRUCTIONS

— Type XW569 13 in. (330 mm) long (for housings one

above the other)

CAUTION

Incorrectly inserted bus cables can destroy the modules installed.

EXCEL 500/600 INSTALLATION INSTRUCTIONS

ELECTRICAL CONNECTIONS

When connecting the controller, both VDE, National Electric Code NEC (or equivalent) and any local regulations concerning grounding and zero voltage must be observed.

Electrical work should be carried out by a qualified electrician. Under no circumstances should spare controller terminals be

used as wiring support points. Doing so could damage the modules.

The electrical connections must be made at the terminal blocks. The corresponding connection diagrams are on the individual modules.

WARNING

Switch power OFF before making connections to or removing connections from terminals to avoid electrical shock or equipment damage.

IMPORTANT (FOR EUROPE, ONLY)

To comply with CE requirements, devices with a voltage in the range of 50...1000 Vac or

75...1500 Vdc which are not provided with a supply cord and a plug or with other means for disconnection from the supply having a contact separation of at least 3 mm in all poles, must have the means for disconnection incorporated in the fixed wiring.

Cable Routing

The minimum distance to power mains cables is 0.4 in. (10 mm) for shielded cable and 4 in. (10 cm) for unshielded cable.

All low-voltage signal and output cables should be regarded as communication circuits in accordance with VDE 0100 and VDE 0800 (or NEC or other equivalent), and should therefore be routed separately from mains cables.

Joining sensor cables should be avoided.

Shielding Input / Output Module and Power Supply Cables

Shielding input and output module and power supply cables is not necessary if the general guidelines for cable routing are observed. If, in certain cases, the routing guidelines cannot be observed, then shielded cable must be used.

The shield must not be terminated at a controller; instead, to avoid ground loops, the shield must be grounded (at only one end) at the control panel.

To prevent ground loops, shielding of input/output cables leading to peripheral devices must be grounded only at the control panel end.

Shielding of Data-Transmitting Cables

Connect the shield of the system bus (C-Bus) to system ground on both ends. Each end of the shield on the system bus should be connected to the system ground terminal of the respective computer module. Do not connect it to the control panel earth or any other earth ground points.

NOTE: The L

To connect remote operator interface units, ready-made cables are available (XW565; XW582, XW583, etc.) with the shield already connected to the computer module plug end.

ONWORKS bus must not be shielded on the

CPU side.

Grounding (XC5010C / XC6010, only)

The controller should be grounded using as short a cable as possible (minimum 16 AWG [1.5 mm²]) between the control panel and the terminal block of the power supply module.

System Ground

WARNING

High voltage

Risk of electrical shock or equipment damage. The controller's system ground must have no

connection with the control cabinet ground!

NOTE: A document providing additional information on

system grounding (if required) is available via the Honeywell Technical Assistance Center (TAC) or, for Honeywell employees, on the Docu Server under: http://web.ge51.honeywell.de/dep/mc/TAC_Tips.

RFI Suppression

Honeywell actuators are RFI (Radio Frequency Interference) suppressed as standard in accordance with VDE 0871/B and VDE 0875/N.

WARNING

A separate CRT 6 or 1450 series (U.S.) transformer must be used for each of the EXCEL 500/600 controller's 24 V supply.

No additional loads may be connected ! Each additional XL500/600 controller requires its own

transformer. An additional transformer, appropriate to the power require-

ments, should be used to power input/output peripherals (e.g. actuators).

LONWORKS Bus Wiring

Connection between the Distributed I/O modules and the CPU are made from the LONWORKS connector module XSL511. The L uses transformer isolation so that the bus wiring does not have a polarity; that is, it is not important which of the two

ONWORKS bus terminals are connected to each wire of the

L twisted pair.

The L

ONWORKS bus 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 L simple structure presents the least number of possible problems, particularly when adding on to an existing bus.

IMPORTANT

Do not use different wire types or gauges on the

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 3000 ft (900 m) for each repeater.

System Bus (C-Bus)

Up to 30 controllers can communicate with one another and a PC central via the system bus. Instead of an Excel 500/600 controller, other system bus compatible components can also be connected. (Excel IRC Multicontroller; Excel EMC).

The system bus must be connected through the individual controllers (open ring).

Table 18. C-Bus submodule baud rates

Submodule Possible baud rates

XD505A 9600 baud

XD508 9600 baud

19200 baud

76800 baud

If the system bus speed throughout the system life-time is restricted to 9600 baud, then a submodule XD505A should be chosen. Otherwise, the XD508 must be used.

NOTE: All communication submodules on one bus must be

of the same type, i.e. either uniquely XD505A or uniquely XD508. Do not use a mix between submodules XD505A and XD508 on the same bus.

IMPORTANT

For communication with more than 9600 baud it is required to enable the termination of the first and the last device on the C-bus (see the following sections). The controllers with termination must be switched ON prior to the controllers in the middle of the C-bus. The C-bus might not work if the controllers with termination are switched OFF.

The maximum communication speed of the XC5010C / XCL5010 is 76800 baud. The XC5010C/XCL5010 can be mounted together with the XC6010 (with XD505A or XD508 submodule) since the XC5010C/XCL5010 communication speed can be changed to match either submodule.

Fig. 82. C-bus topology

IMPORTANT

Star connection is not permissible because uncontrollable line reflections may occur.

For setting up the system bus in the right way, three steps have to be followed:

1. Select submodule for system bus communication (XC6010, only)

2. Specify cable for system bus.

3. Set up submodule (XC6010), CPU module (XC5010C),

or communication module (XCL5010).

NOTE: When changing the baud rate of bus devices, proper

communication cannot be ensured until all bus devices are set to the same baud rate again.

NOTE: When adding or removing a controller to/from the C-

Bus, it may take up to two minutes to re-initialize the bus. During this time, communication on the C-bus is lost.

System Bus Cable Specification

The maximum cable length is 4000 ft (1200 m). There are regional differences as to whether shielded or unshielded cable must/can be used.

IMPORTANT

In Europe, only shielded cable is permitted, while in the US, shielded or unshielded cable can be used.

REMOTE COMMUNICATIONS

The following applies to the XC5010C and XCL5010, only. For remote communications with up to three XBS Building

Centrals, a modem or ISDN terminal adapter can be connected directly to the serial port of the XC5010C CPU (either front or rear connection) or the serial port of the XCL5010.

NOTE: Remote communication via modem or ISDN terminal

adapter requires firmware version V2.1.0 or higher.

NOTE: XBSi building supervisors are not supported for

remote communication.

Modem or ISDN Terminal Adapter Connections

The front serial port of the XC5010C CPU accepts a standard modem cable with a female 9-pin connector.

• 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 XC5010C/XCL5010 CPU 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.

EN1R-1047GE51 R0702

EXCEL 500/600 INSTALLATION INSTRUCTIONS

Automatic Baudrate Synchronization

The default communication speed between the XC5010C/XCL5010 CPU and the local modem/ISDN terminal adapter is 9600 baud.

The communication speed between the XC5010C/XCL5010 CPU 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 a feature that all state-of-the-art modems/ISDN terminal adapters provide 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.

Auto / Manual Answer Detection

The XC5010C/XCL5010 CPU will automatically detect whether the modem/ISDN terminal adapter is initialized in auto-answer or manu-answer mode, and it will set the modem to 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 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 the need 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 not to 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 setup 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.

2. Add the prefix required for access to 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 prior to sending the set-up to the remote Excel 500 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 the XI581/582 Buswide Operator Interface User Guide (EN2B-126GE51) 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.

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

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 500 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 500 controller. The M20T translates the Excel CPU data received in transparent mode into the GSM standard. The M20T behaves like a Hayes-compatible

EN1R-1047GE51 RR0902 44

EXCEL 500/600 INSTALLATION INSTRUCTIONS

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 9600 baud. Due to a special transmission mechanism, the effective communication throughput is lower than 9600 baud – 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.

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 go

missing, 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 9600 baud.

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 ignited.

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 causes the vehicle’s horn to sound or the lights to flash.

• Drivers are advised not to use the handheld

microphone 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

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 a 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).

EXCEL 500/600 INSTALLATION INSTRUCTIONS

GSM Antenna Installation

The maximum antenna cable length is 8.0m (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 amplification of the antenna.

• 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 that is 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 horizontally.

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.

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.

• 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.

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>

EXCEL 500/600 INSTALLATION INSTRUCTIONS

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

controller, 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 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.
