Troubleshooting LEDs - Verasys - Wireless Device - ZFR1800 Series Wireless Field Bus System

The ZFR1825 Coordinator has five LEDs that indicate power, fault status, FC Bus activity, wireless activity, and signal strength. See Figure 1. These status LEDs are described in Table 1.

Table 1. ZFR1825 Coordinator Status LEDs
Name	Color	Normal	Descriptions
Power	Green	On	Off Steady = No power. On Steady = Normal operation (power available from 24 VAC connector or Field ControllerSensor Actuator [FC/SA] Bus IN jack).
Fault	Red	Off	Off Steady = Normal. On Steady = Internal Errors detected.
FC Bus	Green	Blink	Blink - 2 Hz = Normal operation (ZFR1825 Coordinator is receiving BACnet® frames over the wire). Off Steady = Attempting to Auto Baud, or not connected to active MS/TP network. On Steady = Auto Baud complete and not receiving BACnet frames.
Wireless	Green	Blink	Blink - 2 Hz = Normal operation (ZFR1825 Coordinator is receiving BACnet frames over the wire). Off Steady = Not receiving BACnet frames. On Steady = Stopped receiving BACnet frames.
Signal Strength	Green	Signal Strength ¹ Indication: 3 Flashes - Excellent 2 Flashes - Good 1 Flash - Weak OFF for 3 seconds - None	OFF Steady = Not able to start a network. ON Steady with Signal Strength displayed once every 10 seconds = Normal operation (ZFR1825 Coordinator is a member of a wireless network). 5 Rapid Flashes = Network has been started, but no other ZRF Pro devices are seen.

¹ Signal Strength appears once every 10 seconds or when the Network Optimize/Reform button on the ZFR1825 Coordinator is depressed momentarily (less than 5 seconds).
