WEMPE ENI
secondary clocks interface
problem
possible cause/solution
The green LED "State" blinks
continiously (Blink code 4, see
chapter 2.2).
OR
The red LED "Error" shows "Single
flashing" or "Double flashing" (Blink
code 1 or 2)
Clock hands keep showing 12:00,
Connection type is "WEMPE
Masterclock 20102, NTP server.
Communication failure to NTP server.
Check configured IP addresses of NTP server(s).
If DHCP is enabled, check obtaining IP addresses of NTP
server(s) from the offering DHCP server.
Check IP routes from ENI to configured NTP server and
back. The ping tool on the Tools page of the web interface
(see ENI user manual) can assist.
In case of redundant masterclocks check all of the possible
routes.
Check any blocking features (firewall etc.) at every routing
device between ENI and NTP server(s).
Check the NTP server at the configured IP address(es) are
up and running.

Masterclock 20100, 20101.
Communication failure to masterclock.
Check configured ENI V1 compatibility. See chapter 1.3.2
to set the correct protocol version.
Check the IP addresses of ENI and masterclock are in the
same IP subnet or VLAN. The ping tool on the Tools page
of the web interface (see ENI user manual) can assist.
In case of dynamic VLAN: check the Announce protocol is
switched on (Configuration page of ENI's web interface).
Check any blocking features (firewall etc.) at every routing
device between ENI and masterclock.
Check the route of packets between ENI and the supposed
masterclock device.
Check the web interface of the masterclock, are there any
errors regarding the slaveclock?
Check the time broadcast for the right LAN port at the
masterclock is active.
Movement doesn't step, the red
LED "Error" shows "Triple flashing"
(Blink code 3, see chapter 2.2).
Movement wires are shortcut or interrupted. Sometimes a
failure of a movement coil itself. Check the wires from ENI to
the movement. After resolving the cause the movement control
will not recover automatically. To restart the H-Bridge power
supply press the "12h" button while the "Service" switch is set
to "OFF". Most likely the clock hands will then show an
incorrect time. In this case you need to adjust the hands via the
web interface (see ENI user manual).

Temperature alarm. Check the ENI's environment does not
exceed the configured alarm threshold (default: 0…70°C).
