Alarm Messages
When an alarm condition is active, a four-character message is shown on the top line of the
LCD, replacing the normal date information (see example in Figure 8 above). The possible alarm
messages are shown below:
LCD Alarm Alarm Name Description
Hold
Holdover
The TCG 01-G is operating in the “holdover” state (Holdover timer running).
Sync
No Sync
The TCG 01-G is not synchronized to any source and holdover period has expired.
AntL
No Antenna The antenna circuit current drain is low (typically under 3mA). This could be
caused by poor connections, or if the connected antenna has a lower current
drain specification or if a component in the antenna system is providing power to
the antenna and therefore the clock is not seeing a connected load.
AntH
Antenna
Short
The antenna circuit current drain is high (typically over 100 mA). This is caused by
a short in the antenna circuit, or by moisture ingress in the circuit, or if the
antenna connected has a higher current draw specification.
IRIG
No IRIG-B
Input
IRIG-B monitoring is enabled on the P6A and/or P6B input, and a valid IRIG-B
signal is not present on that input.
IPe1
IPv4 Address
Fault on
ETH1
The clock has failed to obtain an IPv4 address via DHCP, or has detected an IP
address conflict, and has adopted an ARP tested Link-Local address
(169.254.xxx.xxx).
When this alarm occurs, the user may need to update their network adapter
settings to a Link-Local address to gain access to the clock.
The alarm will persist until the IPv4 address settings are changed or the clock is
connected to a DHCP enabled network.
FRP Armed
Press Again
to Disarm
Factory
Reset
Procedure
(FRP) Armed
This message appears on the LCD, in place of all other text, when the Factory
Reset Procedure is initiated by the user. The Factory Reset Procedure is used to
reset the TCG 02-G to factory default settings in the case of a lost or forgotten
administrator password, or configuration error that renders the TCG 02-G
inaccessible. Refer to the Tekron Configuration Tool Manual for further
information.
