� Route wires and tie-wrap (Refer to Fig. 12).� All wiring to the Q7750A is supervised, except as

noted.� All circuits are power limited except for AC power

circuits, relay contacts and other circuits as noted.� All field wiring terminals accept 24 AWG to 14

AWG (0.25 sq mm to 2 sq mm) conductors, except as noted.

C-Bus Wiring1. Wire the C-Bus using cable (See Table 1).2. Connect the C-Bus cable by attaching the shield to

terminal 18, the positive lead to terminal 16 and the negative lead to terminal 17 according to job drawings(Refer to Fig. 10).

Power WiringInput Power: 24 Vac, 50/60 Hz.

1. Wire 24 Vac power using the heaviest gauge UL level IV or plenum rated UL level IV wire available, up to 14 AWG (2 sq mm) with a minimum of 18 AWG (1 sq mm) wire. For nonplenum, open areas, run cables exposed (or in conduit if required; see the following NOTES).

NOTES:� The Q7750A Excel 10 Zone Manager must have

a dedicated transformer/power source. Do not power any accessories with the Q7750A Excel 10 Zone Manager transformer/power source.

� Keep the transformer/power source as close as possible to the Q7750A Excel 10 Zone Manager so the power wiring will be as short as possible; the maximum length is 6 ft. 6 in. (2 m).

� (US only) When using a 24 Vac transformer larger than 100 VA, Class II power requirements will be exceeded and the power wiring must be enclosed in conduit.

CAUTIONElectrical Shock Hazard.Power Supply can shock.

Make certain no line power is applied to the transformer/power source to prevent device from being attached with power on.

Mounting base power must remain off until installation and wiring is checked by a control system representative.

2. Connect 24 Vac secondary side of the transformer/power source to terminals 1 and 2 on the mounting base according to job drawings (Refer to Fig. 10).

CHECKOUT

Step 1. Wiring ConnectionsInspect all wiring connections at the Q7750A terminals and verify compliance with job drawings. If any wiring changes are required, first be sure to remove power from the controller before starting work. Pay particular attention to:� 24 Vac power connections. Verify that when there are

multiple Q7750A Excel 10 Zone Managers, each one has a dedicated transformer/power source, with the transformer secondary connected to terminals 1 and 2 on the mounting base, according to job drawings (Refer to Figures 10and 11).

� E-Bus wires. Be sure that the E-Bus wires are attached to terminals 5 and 6 according to job drawings. If the Q7750A device is located at one end of the E-Bus network, check to determine if the termination network was activated by placing two wires (optional jumpers) between the following terminal pairs (Refer to Fig. 11):

4,5 and 6,7 (singly-terminated network)3,5 and 6,8 (doubly-terminated network)

� C-Bus shield. Be sure that the C-Bus shield is attached to terminal 18, the positive lead to terminal 16, and the negative lead to terminal 17 according to job drawings (Refer to Figures 10 and 11).

� Check to see that the ferrite ring is in place on the E-Bus (Refer to Fig. 11).

Step 2. Initial Power UpApply power to the Q7750A. When the Q7750A receives power, the LEDs should appear in normal (uncommissioned and not downloaded) condition (Refer to Table 2).

NOTE: LED 7 is used to display E-Bus network activity. In 1000-series devices it flickers with data being transmitted or received, but in 2000-series devices it flickers only with data being received.

If the status is not correct, push the reset button. Verify that the LED status is correct before proceeding.

IMPORTANTThe CPU reset button deletes the application program in the CPU (stored in RAM). If the reset button is pushed when the CPU contains an application, the device must be re-downloaded.

Step 3. CommissioningThe Zone Manager CPU can be commissioned (given a C-Bus address) using an operator terminal such as the XI581 (on the PC that has the XI584 software and/or CARE installed). This operation is performed the same as for other C-Bus controllers. The following steps describe the most common procedure using the PC to commission the CPU just before downloading from the XI584.

As for other C-Bus controllers, commissioning is required only after an initial power-up or if the CPU reset button was pushed. The following steps assume the Zone Manager Plant and Controller are configured in CARE (see Data File Setup section):

1. Connect the PC COM port to the Zone Manager B-port using the XW565 (or XW566) prefabricated cable.

2. Start XI584. Sign on and run XI581. Assign the controller number using the procedure for C-Bus devices (see the XI584 User's Guide, form 74-3555).

3. Select Continue again, and select Request Download. The operator terminal should then display. Please Execute Download.

4. Select Utilities and drop down to the item File Transfer/Download. Click on All and initiate the Download. Commissioning is complete.

The B-port Transmit and B-port Receive LEDs on the Zone Manager should start blinking rapidly, indicating communication between the PC and the Zone Manager.

Any Download errors or connecting problems appear in the Download Results list box. A loss of communication with the B-port during downloading generates an alarm after three minutes. Press Enter and try again to download.

If there is trouble establishing communication between the PC and the Zone Manager, check the following items:� XW565 cable connections.� XW565 cable connection is to the same PC COM port as

selected in the CARE Download System Settings menu.

IMPORTANTCarefully watch all C-Bus alarm activity following a download. Follow up as necessary on all problem alarms.

DATA FILE SETUPGenerate the CARE data file for the Zone Manager/RIO/Excel 10 VAV2 controllers. This data file has a mix of hardware points for the necessary inputs and outputs to control fans, dampers and other equipment. In addition to the inputs and outputs, a custom control program is written to control the outputs per the sequence. It also resets the program once the data from the operator interface indicates a normal condition for the new dedicated smoke control equipment. Wire conditions must be programmed to provide annunciation of trouble conditions. Also required for a dedicated application is a weekly time program to test control points, fans and dampers by exercising the equipment and verifying feedback automatically during low building activity periods.

Step 4. Troubleshooting.

OPERATIONThe Q7750A controllers have LED indicators that are used to show controller activity. Their function is identified on the controller nomenclature.

Maintenance ProceduresThe system must be maintained in accordance with the system documentation and procedures and practices contained in applicable NFPA and UL standards. The internal memory in this series of controllers is supported by a Varta 6127 CR 1/2 AA 3V lithium battery (not rechargeable). When the battery requires replacement, a low battery condition is indicated on the controller and sent to the MMI and central monitoring station. Replace when needed with the same battery type. For service, contact your local Honeywell Home & Building Control office as listed in the phone book, or contact a regional office as shown at the end of this document.

Problem Description Solution5V (Power) LED not on. No power to the Zone Manager. Apply power or verify the power wiring (voltage must be 20-

30V), check fuses and output from power module or transformer number.
