WEMPE ENI
secondary clocks interface
2.2 Lights
All lights are activated only if the so named switch (see above) is set to "ON"!
Blue LED: "Power"
Shows, that the internal power regulation is up. Wether the ENI is powered from an ethernet switch
(PoE) or an external 24V DC supply, the power is good.
Yellow LED: "Net"
Shows the ethernet connection and activity. If the light is on, the device is connected to a working
ethernet port (hub, switch, router). Flickering shows ethernet activity. In some cases (e. g. connected
to a hub) this activities do not necessary regard the ENI itself but can show any network traffic in that
subnet.
Green LED: "State"
Shows the ENI's operational state through blink codes. Generally the LED blinks at 4 Hz and the code
is the flash count in 1 second.
Blink Code per second
State
Meaning
(off)
INIT
Can't finish initialization, most likely the device is damaged
MAC
No physical network connection
LINK
Network up, but doesn't respond to IP requests
CONN
Network up, but no IP address, possibly waiting for DHCP
(= continous blink) WAIT
Network connection configured, waiting for time source
(on)
RUN
Normal synchronized clock operation mode
Red LED: "Error"
Shows the ENI's error state through blink codes. Generally the LED blinks at 4 Hz and the code is the
flash count in 1 second.
Blink Code per second
Error
Meaning
(off)
OK
No error
PROTO
Ethernet packet error in connection to time source
TOUT
No update from time source within 2x update interval
BRIDGE Clock line output overload / shortcut / disconnection
Alarm can be reset by pushing the 12h while the "Service"
switch is "OFF" after the cause is solved
(= continous blink) TEMP
Temperature out of configured thresholds
(on)
INIT
Can't start initialization, most likely the device is damaged
(real slow)
BOOT
Firmware update mode, no clock operation
