What is the System Touch?

• The System Touch is a touchscreen device with a 5.0 in. color LCD that acts as a front-end interface to controllers on a BACnet network.

The System Touch has built-in temperature and humidity sensors. You can use their values to control equipment.
To set up a System Touch:

1. Connect the System Touch to an MS/TP network.
2. Discover BACnet devices on the same network or on a different BACnet ARCNET or BACnet MS/TP network (page 11).
3. Create the system database.

After you set up your system, you can:

• Schedule when equipment should run
• View alarms
• Link to screens for individual controllers on the network. The information on the controller screens depends on whether the controller is a Carrier controller or a third-party controller, and if it is a Carrier controller, whether it has an Equipment Touch file.

NOTE To see Equipment Touch screens on the System Touch, the controller must have the Equipment Touch file downloaded before you create the database on the System Touch.

Specifications

System Touch screens

The System Touch displays the following screens.

Wiring and mounting the System Touch

CAUTION If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Mounting
You can mount the System Touch:

• In a panel or on the panel door
• On a wall

Wiring
The System Touch is wired to an MS/TP network and a 24 Vac power supply.

Wiring specifications

Power wiring
2-conductor wire 18 AWG for distances up to 100 feet. All transformer secondaries must be grounded. Wiring connections must be under NEC and local codes.
MS/TP network wiring
22 AWG, low-capacitance, twisted, stranded, shielded copper wire. Maximum network length: 2000 feet (610 meters) See MS/TP Networking and Wiring Technical Instructions for more information.

To wire and mount the System Touch

1. Remove the backplate from the System Touch. While firmly pressing the 2 tabs on top of the System Touch, pull on the backplate with your index finger until the backplate releases from the System Touch.

2. Pull the power and communication wiring through the hole in the center of the backplate. See figure in step 5.

3. If wiring 1 cable to the System Touch, cut the shield wire off at the outer jacket, then wrap the cable with tape at the outer jacket to cover the end of the shield wire.
   If wiring 2 cables in a daisy-chain configuration, twist together the shield wires, then wrap the shield wires with tape.

4. Strip about 0.25 inch (0.6 cm) insulation from the end of each wire.

5. Connect wiring to the System Touch as shown below:

CAUTION Allow no more than 0.06 inch (1.5 mm) bare communication wire to protrude. If bare communication wire contacts the cable’s foil shield, shield wire, or a metal surface other than the terminal block, the device may not communicate correctly.

• Attach the backplate to the wall or panel. If mounting in or on a panel:
  • Drill two 3/16 inch (4.8 mm) pilot holes in the panel.
  • Attach backplate using pan head 6-32 x 3/8″ to l/2″ long machine screws. Do not overtighten screws to prevent damage to the plastic housing. RECOMMENDATION Use Loctite 220 on screw threads if the System Touch will be subject to vibration.
• Attach the System Touch to the backplate:
  • Place the bottom of the System Touch onto the backplate by aligning the 2 slots on the System Touch with the tabs on the backplate.
  • Push the System Touch onto the backplate until the tabs at the top of the System Touch snap onto the backplate.
• CAUTION Be careful to avoid bending the connecting pins when attaching the System Touch to the backplate.
• Turn off the controller’s power.
• Connect power wiring to a 24 Vac or 12–24 Vdc power supply.
• Turn on the controller’s power.

Setting up the system

Step 1: Set up communications

1. On the System View (home) screen, touch Setup > Communications.
2. In the left column, select the baud rate of the MS/TP network that the System Touch is on.
3. Use the following information to set the 3 fields on the right.
   Field| Description
   ---|---
   My Device Instance| The System Touch’s BACnet Device Instance. This number must be unique on the MS/TP network. Leave this at the default (160099) unless there is another System Touch or other device on the network with this number.
   My Address| The System Touch’s address. This number must be unique on the MS/TP network. Leave this at the default (127) unless there is another System Touch or other device on the network with this address.
   Destination Network| The network number of the BACnet ARCNET or BACnet MS/TP network that the System Touch will discover controllers on. To discover controllers on the System Touch’s own MS/TP network, this field must be set to

CAUTION The System Touch’s Device Instance number is added to each controller’s alarm recipients list when you create the system database. If you change My Device Instance after you create the database, you must rediscover the controllers to have the System Touch receive alarms from controllers.

4. Touch Save.

Step 2: Discover controllers

In the previous step, you defined the network that the System Touch will discover devices on. To discover controllers:

1. On the Setup screen, touch Discovery > Set Range.
2. System Touch can scan the network for all MAC addresses (0 to 127), or you can define a smaller range of addresses to search for. Touch each field on the Set Range screen, and then enter an address.
3. Touch Save.
4. On the Discovery screen, touch Discover. When discovery is complete, the screen lists every BACnet controller that was found on the network.

NOTE The System Touch cannot discover controllers on a BACnet IP network, so a BACnet router that is on an IP network and the ARCNET or MS/TP network will not be discovered.

Step 3: Create the system database

The discovery process finds every BACnet controller on the network, but you may not want to include them all in the system you are creating. Carrier recommends that you have no more than 32 devices in your system.

1. Touch each controller that you want to include in the system and change its name to something that will be meaningful to a user (maximum 21 characters). For example, if the first controller on the screen controls the lobby, change the name to “Lobby”.
2. Select the controllers that you want to include in the system by touching individual boxes on the left side of the screen or by touching Select All.
3. Touch Create DB (database). The System View screen shows your new system.

NOTE Clear DB deletes the system (controllers, alarms, and schedule groups) and returns the System Touch to its initial state.

Step 4: Set up scheduling functionality

You can define BACnet schedules for any controller whose control program(s) support time schedules.
To allow a user to create schedules on the Equipment Touch:

1. In the i-Vu® or Field Assistant tree, right-click the controller, and then select Driver Properties.
2. On the Settings tab, scroll down to TouchScreen Control and verify that TouchScreen Schedule Edit Enable is checked.

CAUTION If scheduling for this system will be done in the i-Vu® interface, you should disable scheduling in the System Touch so that they do not overwrite each other’s schedules. To disable scheduling, uncheck TouchScreen Schedule Edit Enable.
See “To create a schedule for a group of equipment” in the System Touch User Guide.

Step 5: Optional – Adjust touchscreen settings

If needed, adjust the following touchscreen settings:

• The time of inactivity before the System Touch returns to the Home screen
• The location, units, and offset of temperature and humidity sensor values
• Whether the System Touch makes a sound when you touch the screen
• Whether the System Touch makes a warning sound when it receives an alarm
• The language used for System touchscreens
• The User or Admin password, if allowed

See To edit touchscreen settings

Using System Touch’s temperature and humidity sensors to control equipment

To set up the sensors on the System Touch
Go to Setup > Touchscreen Setup > Sensor Setup.
On this screen, you can:

• Select temperature units—The sensor’s temperature can be requested by a controller’s control program. Select whether the temperature is to be returned as Deg F or Deg C.
• Set an offset—Enter a correct temperature/humidity value to create an offset for all future values.

To use the temperature or humidity value in a control program

1. In Snap, place an Analog Network Input macroblockin your control program.
2. In the macroblock’s Address field, enter bacnet://160099/ and then one of the following:
