LED Error Codes : Fluke Process Instruments

Introduction

Vector devices incorporate two multi-colour LEDs which flash to indicate various operations, states and errors. This quick guide discusses the various LED flash sequences and colour combinations that a Vector 4D may output when powered.

In all cases, Vectors should be running latest firmware, see here.

Power Up Sequence

When first switched on, a Vector 4D device will flash the following sequence to indicate a successful power up:
1. Both LEDs Red (<1s)
2. Both LEDs Yellow (2-30s)
3. Both LEDs Green (~30s)
4. Both LEDs Blue (~1s)
5. Both LEDs OFF

If the power up sequence does not complete successfully, see 'Errors and Warnings' below...

Errors and Warnings

The below error and warning indicators are usually solvable, just follow the instructions in the Fix column:

LED1	LED2	Activity	FIX
Solid Green	Solid Green	This is part of the Boot sequence, but if it sticks at this point and does not complete, then it is a problem.. This issue will only be seen on power up. Note that a device in a watch dog reset loop may show this repeatedly.	1. Ensure that the SD card has not inadvertently popped out during installation. Reseat it to be sure. For help locating the SD card, see here. 2. Remove SD Card and re-image, if that fails... 3. Replace SD Card with imaged card.
Solid Yellow	1 Red pulse	Un-configured / Illegal Configuration	1. Connect to Vector and check / reconfigure (on SafeCount variant Vectors - run the setup wizard) 2. Factory default and start again.
Solid Yellow	2 Red pulses	Auto Height Detect Failure	1. Install device on ceiling if not done so already. 2. Try the 'Auto-Height' function again. 3. Ensure that the installation is valid and the Vectors view is not obscured. 4. Enter height manually.
Solid Yellow	3 Red pulses	Stored Height & Detected Height Differ	1. Click Auto Height button in setup
Solid Yellow	4 Red pulses	Tilt Limit Exceeded	1. Re-install Vector with less of a tilt angle
Solid Yellow	1 Yellow pulse	Video failure	1. Reboot the Vector. 2. Contact Irisys support
Solid Yellow	2 Yellow pulses	Voltage out of range	Check power supply
Solid Yellow	1 Green pulse	Outgoing connection failure	1. Check Outbound connection settings & IP/DNS settings. 2. Check connection
Solid Yellow	2 Green pulses	Master missing node(s)	1. Check wiring connections between master & nodes. 2. Reconfigure
Solid Yellow	3 Green pulses	Node missing master	1. Check wiring connections between master & nodes. 2. Reconfigure
Solid Yellow	1 Blue pulse	Illuminators are (temporarily) disabled	Most likely reason for this is that it is powered on but is on a desk and pointing upwards. Install on ceiling and illuminators will be re-enabled
Solid Yellow	1 Red pulse ->1 Blue pulse	HW Failure	1. Reboot the Vector. 2. Contact Irisys support

A Vector will always flash one or more error sequences when powered up but not installed correctly, for example when connected locally to a device on your desk. In this case it will flash the error that the tilt angle has been exceeded (if it is pointing up), or that the auto height has failed (if it is pointing down), or that the auto height is different to the configured height value. These are perfectly normal and to be expected – once installed on the ceiling, looking down, these errors can easily be fixed through standard configuration.

Very First Power Up

On a brand-new device the following additional LED flash sequences may also be seen:

LED1	LED2	Activity
Red alternating long pulses (1 sec on, 1 sec off)	Red alternating long pulses (1 sec off, 1 sec on)	Device Warm-up
Blue Alternate	Blue Alternate	Height Auto-Config
Yellow Alternate	Green Alternate	Certificate Is Being Generated *

* Note: certificate generation is required for secure communications and can take up to 3 minutes to generate.

Configuration LED Sequences

The following LED flash sequences are specifically highlighted as these will be seen when connected to the device and configuring it:

These flash sequences are normal, and indicate expected operation.

LED1	LED2	Activity
Green synchronous pulses	Green synchronous pulses	Identify (used by the RIFT setup software and other tools to indicate the current selected device)
1 Red blip	1 Red blip	Heartbeat every ~5 seconds (device ‘alive’ and well)
1 Green blip	Off	Count increment on first register
Off	1 Red blip	Count increment on second register
Blue Alternate	Blue Alternate	Height Auto-Configuration
Yellow Alternate	Green Alternate	Certificate Is Being Generated *

* Note: certificate generation is required for secure communications and can take up to 3 minutes to generate.

Correct Running Flashes

If running correctly, a Vector 4D device will flash the above Power Up Sequence and then start counting (if configured to do so). Correct operation is indicated by a heartbeat pulse, and any counting indications. If your Vector is powered but no Heartbeat flash indication is observed, this would suggest an issue with either the power supply or the power cable:

LED1	LED2	Activity
1 Red blip	1 Red blip	Heartbeat (indicating correct operation / device ‘alive’)
1 Green blip	Off	Count increment on first register
Off	1 Red blip	Count increment on second register

Additional LED Indications

The following LED flash sequences are perfectly normal but are only seen when specific events occur, e.g. if a device is factory reset, or ‘Auto Height'-ed in the settings:

LED1	LED2	Activity
Red alternating pulses	Green alternating pulses	Factory reset button pressed
Solid Green	Green pulses	Programming
Green synchronous pulses	Green synchronous pulses	Identify (used by tools to indicate the current selected device)
Red alternating long pulses (1 sec on, 1 sec off)	Red alternating long pulses (1 sec off, 1 sec on)	Device Warm-up
1 Red blip	1 Red blip	Heartbeat (device ‘alive’)
1 Green blip	Off	Count increment on first register
Off	1 Red blip	Count increment on second register
Red / Green / Blue Sequence	Red / Green / Blue sequence	Factory LED test
Blue Alternate	Blue Alternate	Height Auto-Config
Yellow Alternate	Green Alternate	Certificate Is Being Generated *

* This is required for secure communications and can take up to 3 minutes to generate.

Hardware Failures

The below indicators are only usually solvable by a power off and on, but may indicate a hardware failure of some kind requiring a replacement unit to correct:

LED1	LED2	Issue	FIX
Solid Red	1 Blue pulse	Hardware Failure	1. Power Vector Off, wait 10 seconds and the power on again. 2. Contact Irisys support
Solid Red	2 Blue pulses	File System Failure	1. Power Vector Off, wait 10 seconds and the power on again. 2. SD Card will need re-imaging or replacing and imaging. See here for SD card image files and instructions.
Solid Red	3 Blue pulses	General Failure	1. Power Vector Off, wait 10 seconds and the power on again. 2. Contact Irisys support
Solid Red	1 Red pulse	ToF Failure	1. Power Vector Off, wait 10 seconds and the power on again. 2. Contact Irisys support
Solid Red	2 Red pulses	Video Failure	1. Power Vector Off, wait 10 seconds and the power on again. 2. Contact Irisys support
Solid Red	1 Yellow pulse	Illuminator Failure	1. Power Vector Off, wait 10 seconds and the power on again. 2. Contact Irisys support

If you cannot clear the above Hardware failure errors with a power off reset, contact Irisys support for more guidance and to check the warranty status.
