ECB Series_IG_24_EN
0 to 10V output, 24VAC powered actuator is not
moving.
Check the polarity of the 24VAC power supply connected to the actuator while connected to the controller. Reverse the
24VAC wire if necessary.
Wireless devices not working correctly
Device not associated to controller
Using EC-
gfxProgram, check the configuration of the input. Refer to the EC-gfxProgram user guide for more information.
Power discharge
1. Recharge device with light (if solar-powered) or replace battery (if battery-powered),
2. Ensure sufficient light intensity (200lx for 4 hours/day).
Device too far from the Wireless Receiver
Reposition the device to be within the range of the Wireless Receiver. For information on typical transmission ranges, refer
to the
Open-to-Wireless Application Guide.
Configuration problem
Using the device configuration plug-in or wizard, check the configuration of the input. Refer to the Wireless Battery-less
Sensors and Switches Solutions Guide for more information.
Rx/Tx LEDs
RX LED not blinking
Data is not being received from the BACnet MS/TP data bus.
TX LED not blinking
Data is not being transmitted onto the BACnet MS/TP data bus.
Status LED– Normal Operation
One fast blink
Initialization: The device is starting up.
Fast blink continuous:
(150ms On, 150ms Off, continuous)
Firmware upgrade in progress. Controller operation is temporarily unavailable. The new firmware is being loaded into
memory. This takes a few seconds. Do not interrupt power to the device during this time.
The Status LED is always OFF
The controller is operating normally.
Status LED blink patterns – Repeats every 2 seconds (highest priority shown first)
Long Long Long blink
(800ms On, 300ms Off, 800ms On, 300ms Off,
800ms On)
The device has not received a BACnet token, and therefore cannot communicate on the network: Verify that the controller’s
MAC Address is unique on the BACnet MS/TP Data Bus – see Device Addressing. Make sure the controller’s BAUD rate is
the same as the BACnet MS/TP Data Bus’ BAUD rate (see Setting the BAUD Rate (optional)). Verify that the Max Master is
set high enough to include this controller’s MAC Address (See the Network Guide).
Short Short Long blink
(150ms On, 300ms Off, 150ms On, 300ms Off,
800 ms On)
Poor-quality power; The device has browned-out: The voltage at the 24VAC and 24VCOM terminals has gone below the
device’s acceptable limit during power up.
Short Long blink
(150ms On, 300ms Off)
Invalid MAC address: The device’s MAC address is set to zero (0) or is set to an address higher than the Max Master. See
the Network Guide.
