CHECKOUT
Step 1. Check Installation and Wiring
Inspect all wiring connections at the controller terminals, and 
verify compliance with installation wiring diagrams. 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 multiple controllers 
being powered by the same transformer are wired with the 
transformer secondary connected to the same input 
terminal numbers on each controller. Use a meter to 
measure 24 Vac at the appropriate terminals (see Fig. 13 on 
page 11). Controller configurations are not necessarily 
limited to three devices, but the total power draw, including 
accessories, cannot exceed 100 VA when powered by the 
same transformer (U.S. only).
— Be sure that each controller has terminal 3 wired to a 
verified earth ground, using a wire run as short as possible 
with the heaviest gauge wire available, up to 14 AWG (2.0 
sq mm) with a minimum of 18 AWG (1.0 sq mm) for each 
controller in the group (see Fig. 13 on page 11).
— Verify that Triac wiring of the digital outputs to external 
devices uses the proper load power and 24 Vac common 
terminal (digital output common terminals) for High-Side 
switching.
NOTE: All wiring must comply with applicable electrical 
codes and ordinances or as specified on installation 
wiring diagrams.
For guidelines for wiring run lengths and power budget, see 
“Power” on page 7.
VERIFY TERMINATION MODULE PLACEMENT (MULTIPLE 
CONTROLLERS ONLY)
The installation wiring diagrams should indicate the locations 
for placement of the 209541B termination module(s). See 
Fig. 14 on page 12 and refer to the “L
ONWORKS® Bus Wiring 
Guidelines,” form 74-2865, and the “FTT Termination Module 
Installation Instructions,” form 95-7554. 
Correct placement of the termination module(s) is required for 
proper L
ONWORKS® Bus communications.
Step 2. Startup
Refer to Fig. 25 and the following text for startup information.
Fig. 25. LED, service pin, and network 
connection locations.
BROADCAST THE SERVICE MESSAGE
The Service Message allows a device on the L
ONWORKS® Bus 
to be positively identified. The Service Message contains the 
controller’s Neuron
®
 ID number and node type. This is used to 
confirm the physical location of a particular Spyder Lon device 
in a building.
• To send the Service Message from the controller, press the 
N
EURON® Service Pin pushbutton on the controller (see Fig. 
25 above, and Fig. 16 and Fig. 17 on page 14). This button 
sends out the Service Message when it is pressed, 
regardless of the controller’s current mode of operation.
Equipment Damage Hazard.
Can cause controller damage or failure.
Do not use any metal object to press the N
EURON® 
Service Pin. Use a plastic rod or wood device (such as 
a pencil with the lead broken off) to press the pin. Using 
a metal object can damage the circuitry of the 
controller.
CONTROLLER STATUS LED:
The LED on the front of the controller provides a visual 
indication of the status of the device. When the controller 
receives power, the LED appears in one of the following 
allowable states, as described in Table 8.
