HONEYWELL EXCEL 5000 OPEN SYSTEM

GENERAL INFORMATION

In addition to the four fast digital inputs and four relays (two normally open, two changeover) present in every Excel Smart I/O, specific models are equipped as follows:

Removable Terminals (XFC1Dxx), 110 Vac (long housing)

• XFC1D06001: four universal inputs (NTC20k), two

0...10 V analog outputs, built-in transformer, six manual overrides, ten status LEDs

Removable Terminals (XFC2Dxx), 230 Vac (long housing)

• XFC2D05001: two universal inputs (PT1000, Ni1000, or Ni1000TK5000), two 0...10 V analog outputs, built-in transformer, six manual overrides, ten status LEDs

• XFC2D06001: four NTC20k universal inputs, two 0...10 V analog outputs, built-in transformer, six manual overrides, ten status LEDs

Removable Terminals (XFC3Dxx), 24 Vac (short housing)

• XFC3D04001: two universal inputs for three-wire PT100 sensors, two 0...20 mA analog outputs, six manual overrides, ten status LEDs

• XFC3D05001: two universal inputs (PT1000, Ni1000, or Ni1000TK5000), two 0...10 V analog outputs, six manual overrides, ten status LEDs

• XFC3D06001: four NTC20k universal inputs, two 0...10 V analog outputs, six manual overrides, ten status LEDs

Fixed Terminals (XFC1Axx), 110 Vac (long housing)

• XFC1A06001: four universal inputs (NTC20k), two

0...10 V analog outputs, built-in transformer

Fixed Terminals (XFC2Axx), 230 Vac (long housing)

• XFC2A05001: two universal inputs (PT1000, Ni1000, or Ni1000TK5000), two 0...10 V analog outputs, built-in transformer

• XFC2A06001: four NTC20k universal inputs, two 0...10 V analog outputs, built-in transformer

Fixed Terminals (XFC3Axx), 24 Vac (short housing)

• XFC3A04001: two universal inputs for three-wire PT100 sensors, two 0...20 mA analog outputs, short housing

• XFC3A05001: two universal inputs (PT1000, Ni1000, or Ni1000TK5000), two 0...10 V analog outputs

• XFC3A06001: four NTC20k universal inputs, two 0...10 V analog outputs

The term "universal inputs" refers to analog inputs for temperature-sensor signals which can be configured as voltagevariable or slow digital inputs (e.g. for dry-contact / opencollector signals). In the case of the XFC3A04001 and XFC3D04001, reconfiguration of the two 3-wire PT100 universal inputs yields four voltage-variable or slow digital inputs.

Further, the universal inputs and the analog outputs each feature an extra 24 Vac power output terminal capable of powering field devices.

BEFORE INSTALLATION

IMPORTANT

INSTALLATION

Mounting

The Excel Smart I/O is available with either

• short (W x L x H = 126 x 76 x 110 mm) or

• long (W x L x H = 180 x 76 x 110 mm)

housings (see Fig. 1) conforming to IP20/30. The mounting procedures are similar for both sizes.

The Excel Smart I/O is suitable for mounting on both a standard rail (DIN EN 50022-35 x 7,5) for installation in wiring cabinets or fuse boxes, and on walls/ceilings.

Excel Smart I/O

AND XFC3Dxx MODULES

INSTALLATION INSTRUCTIONS

It is recommended that the Excel Smart I/O be kept at room temperature for at least 24 h before applying power to allow the evaporation of any condensation resulting from low shipping / storage temperatures.

CAUTION

To avoid electrical shock or equipment damage, you must turn OFF the power supply before attaching / removing connections to/from any terminals.

After mounting the Excel Smart I/O, provide for cable access by snipping out the terminal protection covers' cut-out tabs and snap (by hand) the covers (available in packs of 8) into place onto the housing. To remove a cover, place a screwdriver in the leverage slot (see Fig. 10) and pry it loose.

Power Supply

General Information

All module inputs and outputs are protected against overvoltages of max. 40 Vdc and 24 Vac.

NOTE: Local wiring guidelines (e.g. VDE 0100) may take

precedence over recommendations provided in these installation instructions.

NOTE: To comply with CE requirements, devices with a

voltage in the range of 50 to 1000 Vac or 75 to 1500 Vdc lacking a supply cord, a plug, or other means for disconnection from the power supply having a contact separation of at least 3 mm at all poles must have the means for disconnection incorporated in the fixed wiring.

Models equipped with a built-in transformer are powered with either:

• 230 Vac (-15%/+10%), 50 or 60 Hz (XFC2xx) or

• 110 Vac (-15%/+10%), 50 or 60 Hz (XFC1xx)

When not supplying external devices with 24 Vac, these models have a power consumption of under 17.5 VA.

Models with a short housing are powered with 24 Vac (±20%), 50 or 60 Hz from an external transformer (which can power more than a single Excel Smart I/O; in this case, it is essential that the different Excel Smart I/O's not be connected with each other in any additional fashion, e.g. by being grounded, or by being connected to the same field devices). The 24 V models have a power consumption of under 6.5 VA.

Each universal input and each analog output features a 24 Vac power output terminal capable of supplying power to field devices. If the module is supplied with direct current, these power output terminals will deliver only direct current.

NOTE: The max. combined current draw of all of the field

devices supplied by the power output terminals of a single Excel Smart I/O equipped with a built-in transformer must not exceed 300 mA (cos φ = 1) for prolonged periods of time. In the case of an Excel Smart I/O powered by an external transformer, the max. combined current draw is 500 mA (cos φ = 1). Disregarding these limits can result in the destruction of the built-in / external transformer.

Connecting to the Power Supply

The Excel Smart I/O is connected to the power supply as shown in Fig. 4 or Fig. 5, as the case may be.

All wiring must comply with applicable electrical codes and ordinances. Refer to job or manufacturers’ drawings for details. Use a min. of 18 AWG (1.0 mm

long housing: 100 mm

AWG (2.5 mm

) for all power wiring.

Do not reverse the polarity of the power connection cables. Also, avoid ground loops (i.e. do not connect one field device to several Excel Smart I/O modules): Failure to observe these instructions may result in short circuits, damaging your devices.

In the case of models with removable terminals, an orangecolored T terminal plug may be used. In this case, the T terminal plug is plugged into pins 1 and 2 (24 Vac models) or pins 43 and 44 (110 Vac and 230 Vac models).

If power is supplied via T terminal plugs, it is possible to disconnect individual Excel Smart I/O modules from the power supply without disturbing the operation of other devices powered by the same source.

LonWorks Communications

General Information

The Excel Smart I/O is equipped with a free topology transceiver (FTT10A) for communicating on L works. The L

ONWORKS network is insensitive to polarity,

eliminating installation errors due to miswiring. Different network configurations (daisy-chain, loop, and star configurations, or any combination thereof) are possible (see also: Excel 50/500 L

ONWORKS Mechanisms Interface

Description, EN0B-0270GE51).

Connecting to the LONWORKS Network

IMPORTANT REMARKS:

— Do not bundle wires carrying field device signals or

ONWORKS communications together with high-voltage

power supply or relay cables. Specifically, maintain a min. separation of 3 inches (76 mm) between such cables. Local wiring codes may take precedence over this recommendation.

Inputs/Outputs

General Information

Depending upon the model, the units are equipped with removable or fixed screw-type terminal blocks. Removable screw-type terminal blocks allow the terminal assignments to

be made before plugging them into the unit, and to be preserved after unplugging them from a unit requiring repair or replacement. The terminal blocks are arranged on two sides: the relay side and the low-voltage side.

• The relay side consists of a single row of terminal blocks for the connection of cables to the relays. In the case of models with a long housing, the high-voltage power supply, too, is connected on this side.

• The low-voltage side consists of two rows of terminal blocks for the connection of cables to all other input / outputs. In the case of models with a short housing, the low-voltage power supply, too, is connected on this side.

NOTE: VDE guidelines prohibit mixing low-voltage and high-

voltage signals on the relay side.

Wiring the Inputs/Outputs

Use a min. size of 20 AWG (0.5 mm2) and a max. of 14 AWG (2.5 mm all input/output cables is 1300 ft (400 m).

Two wires with a total thickness of 14 AWG can be twisted together and connected using a wire nut (include a pigtail with this wire group and attach the pigtail to the individual terminal block). Deviations from this rule can result in improper electrical contact. Local wiring codes may take precedence over this recommendation. If cable binders are used, pass them through the corresponding eyelets.

Terminal Assignment

Fig. 8 depicts the terminal assignments of a typical Excel Smart I/O. Refer to job drawings for specific wiring diagrams.

Fig. 8. Example terminal assignment

In the case of models not equipped with manual override switches, a terminal assignment label (see Fig. 9) is fixed to the top of the housing. In the case of modules equipped with manual override switches, this label is included in the delivery. Attach this label to the terminal protection cover or swivel label holder, as appropriate. Unused terminals are marked with an "x" on the device type label. In the case of models powered with 110 Vac or 230 Vac, hook up the external power supply to terminals 1, 2, 22, and 23, which are connected to the 24 Vac internal transformer; these terminals must not be used for connecting an external 24 Vac power supply.

Fig. 9. Example terminal assignment label

After completing terminal assignment, perform a wiring check using the XILON Handheld MMI. See XILON Handheld Tool for Wiring Checks User Guide (EN2B-0214GE51) for details.

Hardware Features

Fast Digital Inputs

Every Excel Smart I/O is equipped with four fast digital inputs, each with its own ground terminal pin. The fast digital inputs are not electrically insulated from the CPU core.

• In order for the software to detect that a fast digital input is closed, the resistance of the dry contact must be less than 200 Ω, the incoming current must not exceed 3 mA, and the voltage must be less than 0.8 Vdc.

• In order for the software to detect that a fast digital input is open, the resistance of the dry contact must exceed 50 kΩ, and the voltage must be greater than 10 Vdc.

• In order to totalize signals (max. frequency = 20 Hz), the driving signal must be stable for a min. of 22 ms.

Relays

Every Excel Smart I/O is equipped with four relays, including two normally-open relays and two changeover relays. During power-off and after a reset (before the software begins working), the hardware default position of a normally-open relay is open.

• In order to switch reliably, the relays require a min. current of 50 mA.

• The normally-open contacts are designed for a max. continuous current of 6 A (at max. 230 Vac / max. 24 Vdc).

• The normally-closed contacts are designed for a max. continuous current of 1 A (at max. 230 Vac / max. 24 Vdc).

• The max. combined allowable current flowing through all relays simultaneously is 24 A (continuous) (at max. 230 Vac / max. 24 Vdc).

• The max. peak current (10 ms) at the normally-open contact is 50 A at cos φ = 1 and 30 A at cos φ = 0.6.

After these relays have been configured using Honeywell's LonMaker for Windows™ plug-in, floating actuators can be directly connected to them (max. two relays per floating drive).

NOTE: If inductive components are to be connected to the

relays and if these relays switch more often than once every two minutes, these components must be prevented from causing harmful interference to radio or television reception (conformance with EN

45014).

Accuracy and Resolution of Universal Inputs

The Excel Smart I/O is equipped with universal inputs for reading analog signals from different types of temperature

EN1B-0180GE51 R1004B / 95-7666-5

EXCEL SMART I/O MODULES

sensors. Each universal input features an extra terminal capable of supplying 24 Vac power to sensors.

At 25 °C, NTC sensors (e.g. Siemens type B57111-J2203-A3) display a resistance of 20 kΩ. Table 1 lists the typical accuracy and resolution of inputs reading signals from such sensors.

Analog Outputs

The Excel Smart I/O is equipped with two analog outputs (0...10 V or 0...20 mA, depending upon the specific model). Each analog output features a 24 Vac power output terminal capable of supplying power to actuators.

Status LEDs and Manual Override Switches

The XFC1D06001, XFC2D05001, XFC2D06001, XFC3D04001, XFC3D05001, and XFC3D06001 are equipped with six manual override switches and ten status LEDs (see Fig. 10).

The status LEDs can be freely programmed to indicate the current state of any digital input or relay. By default, status LEDs 1 through 4 are assigned to digital inputs 1 through 4, respectively, with "red = ON" and "green = OFF." Status LEDs 5 through 8 are assigned to relays 1 through 4, respectively, with "yellow = ON" and "unlit = OFF." LEDs 9 and 10 are permanently assigned to analog outputs. In the case of normally-open contacts, "lit = CLOSED CONTACT."

The manual override switches can be freely assigned to any relay or analog output (including hardware). By default, manual overrides 1 through 4 are assigned to relays 1 through 4, respectively, with "0 Position = OFF" and "1 Position = ON." Manual overrides 5 and 6 are assigned to analog outputs 1 and 2, respectively, with "0 Position = 0%" and "1 Position = 100%."

Troubleshooting

All models feature a LONWORKS service LED and corresponding service button (accessible from the outside on top of the module) for use in troubleshooting. When the service button is pressed, the following actions take place:

• The service pin message (containing the Neuron ID and the Standard Program ID) is broadcast on the L

ONWORKS

network (the service pin message is broadcast whenever the service button is pressed, after each reset due to power-up, after every software reset, and whenever the mode is changed from offline to online).

• When the service button has been pressed longer than 30 sec, the node reverts to normal mode (provided it has been in the manual override mode via nviAoManOvrd or nviDoManOvrd).

For more information on standard service LED behavior, refer to Motorola L

ONWORKS Technology Device Data Manual,

page AL-190.

Table 4. Service LED Behaviors and Meanings

LED Blinking Pattern Meaning

1 LED remains OFF after power-up. Defective device hardware. Suspect power supply problems, clock 2 LED is ON continuously, even before first power-up. Defective hardware.

3 LED flashes at power-up, goes OFF, then comes ON solid. Node is applicationless. 4 LED flashes briefly once every second. This device is probably experiencing continuous watchdog resets,

5 LED blinks ON and OFF at 0.5 Hz. Node is unconfigured but has an application. 6a

OFF duration ≈ 10 sec. Afterwards, the service LED turns ON and stays ON, indicating completion of the blanking process.

OFF duration ≈ 1 sec. Afterwards, the service LED turns ON and stays ON.

6c OFF duration is 1...15 sec, depending on the application size

and the system clock. Afterwards, the service LED begins blinking ON and OFF at 0.5 Hz.

6d OFF duration is indefinite (1-15 sec to load internal EEPROM;

stays OFF). 7 LED remains OFF after a short ON duration. Node is configured and running normally. 8 LED blinks ON for 1 sec and OFF for 1 sec five times in

succession and then stays OFF for 5 sec, after which the

pattern is repeated. 9 LED blinks ON for 1 sec and OFF for 1 sec four times in

succession and then stays OFF for 5 sec, after which the

pattern is repeated.

10 LED blinks ON for 1 sec and OFF for 1 sec three times in

succession and then stays OFF for 5 sec, after which the

pattern is repeated.

Possible problem causes and the corresponding recommended actions are as follows:

Power LED is not lit → check the power supply

• CPU not working → contact your Honeywell dealer

• Incorrect wiring → contact your Honeywell dealer

• Defective hardware → contact your Honeywell dealer

Check if the behavior is changed if you:

1. Push the L Excel Smart I/O module. The L

ONWORKS service button to reconfigure the

ONWORKS service LED will

remain lit as long as the service button is pushed. If this is not the case, the hardware is defective.

2. Switch the power OFF / ON.

Please contact Honeywell if the above actions do not solve the problem. Further, more information is available under the following URL:

physical outputs are unaffected. Coprocessor identification. After reset (power-up), the Neuron Chip

waits for the coprocessor's ID message (sent periodically until acknowledged). While waiting, the application remains OFF. This wait status will remain if the hardware identification fails e.g. because the Neuron application does not match the hardware. The module has been switched to the manual override mode. Pressing the service button for more than 30 sec will disable the manual override mode.

Optional Features

Optional features include the terminal protection covers (available in packs of 8) required for wall/ceiling mounting and
