[. . . ] Excel 10 W7754 dimensions (in mm) The Excel 10 W7754 FCU Controller is suitable for mounting on a standard rail (DIN EN 50022-35 x 7, 5), on walls/ceilings, as well as for installation in wiring cabinets or fuse boxes. Drilling template (view from above) DIN Rail Mounting/Dismounting screwing nose (oval hole) eyelets for cable binders screwing nose (round hole) CAUTION In order to conform with IP30, when installed on walls or ceilings, the Excel 10 W7754 FCU Controller must be equipped with the optional terminal protection cover (see section "Terminal Protection Cover" on page 7). After mounting the Excel 10 W7754 FCU Controller onto the wall or ceiling, provide for cable access by snipping out the terminal protection cover's cut-out tabs and snap it (by hand) into place on the housing. To remove the cover, place a screwdriver in the leverage slot and pry it loose. Terminal Assignment The Excel 10 W7754 FCU Controller features two rows of terminal blocks located on one side for the connection of cables to the relays, inputs, and outputs as well as for connecting the removable power supply terminal plug and removable LONWORKS terminal plug. screwing nose (oval hole) eyelet for cable binder eyelets for cable binders screwing nose stirrup; pull to (oval hole) dismount from rail NOTE: All high-voltage terminal blocks are orange-colored. [. . . ] NOTE: The left DIP switch located on the top of the controller (see Fig. 1 on page 1) is used to indicate that a wall module can be hardwired to the controller. Setting the left DIP switch to USED means that a wall module can be hardwired; setting it to UNUSED means that no wall module can be hardwired. NOTE: The intended use of the wall module's buttons must be configured using Honeywell's LNS plug-in.

Example: The T7560A has a left button which can be configured to act as a fan speed button, a middle button which can be configured to act as a unit ON/OFF button, and a right button for override. If the wall module's LED flashes twice per second, a network command has placed the controller into either the "standby" or the "occupied" mode. If the wall module's LED flashes four times per second, the controller is responding to a network management "wink" command. Different network configurations (daisy-chain, loop, and star configurations, or any combination thereof) are possible (see also Excel 50/500 LONWORKS Mechanisms Interface Description, EN0B-0270GE51). Connecting to the LONWORKS Network IMPORTANT Do not bundle wires carrying field device signals or LONWORKS communications together with highvoltage power supply or relay cables. IMPORTANT Try to avoid installing in areas of high electromagnetic noise (EMI). The unit must be wired to the LONWORKS network using level IV 22 AWG (Belden part number 9D220150) or plenum-rated level IV 22 AWG (Belden part number 9H2201504) nonshielded, twisted-pair, solid-conductor wire. When possible, use Honeywell AK3781, AK3782, AK3791, or AK3792 cable (US part numbers). See Excel 50/5000 LONWORKS Mechanisms, EN0B-0270GE51, for details, including maximum lengths. Use wire with a minimum size of 20 AWG (0. 5 mm2) and a maximum size of 14 AWG (2. 5 mm2). · · · Configuration of the LED to Display Info on Occupancy Mode The wall module's LED can also be configured to indicate the Excel 10 W7754 FCU Controller's effective occupancy mode. Specifically: · If the wall module's LED is OFF, the controller is in the "unoccupied" mode. · If the wall module's LED is ON, the controller is in the "occupied" mode. · If the wall module's LED flashes once per second, the controller is in the "standby" mode. · If the wall module's LED flashes four times per second, the controller is responding to a network management "wink" command. Configuration of the LCD to Display Info on Occupancy Mode The T7560 Wall Module's LCD can be configured to display various symbols to indicate the Excel 10 W7754 FCU Controller's effective occupancy mode. Specifically: · If is displayed continuously, the controller is in the "occupied" or "override" mode; if it flashes, the given mode has been overridden. · If is displayed continuously, the controller is in the "standby" mode; if it flashes, the "standby" mode has been overridden. [. . . ] Controller is probably experiencing continuous LED flashes briefly periodically. LED repeatedly blinks ON for 1 s Controller is unconfigured and OFF for 1 s. Afterwards, the service LED turns ON and remains ON, indicating completion of the blanking process. First power-up with a new PROM on a Neuron 3150 Chip-based customized node. [. . . ]
