[. . . ] Excel 12 housing (side view) DIN Rail Mounting/Dismounting After mounting the unit onto the wall or ceiling, 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. 10 on page 7) and pry it loose. The unit can be mounted onto a DIN rail simply by snapping it into place and securing it with a stopper to prevent sliding. It is dismounted by gently pulling the stirrup located in the base of the housing (see Fig. 2). EYELETS FOR CABLE BINDERS SCREWING NOSE (round hole) Terminal Assignment The terminal blocks are arranged on two sides of the controller: the relay side and the low-voltage side. [. . . ] Configuration of the LED to Display Info on Overrides The wall module's LED can indicate if an override has been activated by either the wall module's bypass button being pushed or because the Excel 12 has received a network command. Specifically: If the wall module's LED is OFF, then no override (from the wall module or the LONWORKS network) is currently in effect. If the wall module's LED is ON continuously, the bypass button or a network command has placed the Excel 12 into the "occupied" or "bypass" mode (however, if the bypass button is again pushed or if a cancellation network command is received or if the bypass time expires, the Excel 12 will return to its scheduled occupancy mode). If the wall module's LED flashes once per second, the bypass button or a network command has placed the Excel 12 into the "unoccupied" mode (however, if the bypass button is again pushed or if a cancellation network command is received, the Excel 12 will return to its scheduled occupancy mode). If the wall module's LED flashes twice per second, a network command has placed the Excel 12 into either the "standby" or the "occupied" mode. and mean that the Excel 12 is OFF, but that "frost protection" has been enabled. IMPORTANT Do not bundle wires carrying field device signals or LonWorks communications together with high-voltage 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 nos. ). See Excel 50/5000 LonWorks Mechanisms, EN0B-0270GE51, for details, including max. 9 via terminal pins 3 and 4 (black screw-type T terminal plug) underneath the terminal protection cover (if present) located on the low-voltage side. Terminal 24 and 25 are used to connect further devices to the LONWORKS network. Connection of CO2-Sensor A CO2-sensor (e. g. C7110D1009) may be connected to analog inputs 1, 5, or 7 for air-quality control. W7704 TEMP.

LonWorks Communications The Excel 12 is equipped with a free-topology transceiver (FTT10A) for communicating on LONWORKS® networks. The LONWORKS network is insensitive to polarity, eliminating the possibility of 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 LONWORKS Mechanisms Interface Description, EN0B-0270GE51). All Excel 12 controllers feature a LONWORKS service LED and service button (see section "Troubleshooting" on page 6). General Information Inputs/Outputs Use a min. length of 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). Wire to the terminal blocks as follows: Wiring the Inputs/Outputs 5 EN1B-0201GE51 R0110F EXCEL 12 MODULES 1. Insert it at the required terminal location, and tighten the screw to complete the termination. [. . . ] First power-up with a new PROM on a Neuron 3150 Chip-based custom node.
