Errors in the E3X-SRT21
Indicator status
Probable cause
Remedy
PWR indicator not lit. Power is not supplied to the Unit.
Supply the communications power to the Unit through the
CompoBus/S Communications Connector.
The current and voltage are outside
the permissible range.
Use the current and voltage within the permissible range.
The Unit is faulty.
Replace the Unit.
U.ERR indicator lit
red.
The Unit is faulty.
Replace the Unit.
ERR indicator lit red. A communications error has occurred
in a slave communicating on the Com-
poBus/S network, and the slave has
been disconnected from communica-
tions.
Check the following items and then restart the Unit.
• Are cable lengths (trunk/branch lines) suitable?
• Are cables shorted, broken, or loose?
• Is terminating resistance connected to the end of the
communications line only?
• Is there too much noise?
The Unit is faulty.
Replace the Unit.
PWR indicator lit
green, COMM, ERR,
U.ERR indicators not
lit.
A CompoBus/S communications error
has occurred.
Check the following items and then restart the Unit.
• Are cable lengths (trunk/branch lines) suitable?
• Are cables shorted, broken, or loose?
• Is the wiring configuration correct?
• Is terminating resistance connected to both ends of the
trunk line only?
• Is there too much noise?
• Is the node address setting correct?
• Are the master and slave using the same communica-
tions mode?
• Is the power turned ON to the master?
The Unit is faulty.
Replace the Unit.
SS indicator not lit.
No Sensors are connected.
Connect the Sensors correctly.
The Sensor adjacent to the Fiber
Amplifier Sensor Communication Unit
is faulty.
Replace the Unit adjacent to the Communication Unit.
The power was turned ON while the
Mobile Console was connected.
Temporarily disconnect the Mobile Console.
The Unit is faulty.
Replace the Unit.
SS indicator lit red.
One or more of the connected Sen-
sors is faulty.
Replace the Sensor.
One or more of the connected Sen-
sors has been disconnected.
Connect the Sensors correctly.
The number of registered Sensors is
incorrect.
Register the number of Sensors correctly.
One or more of the connected Fiber
Amplifier Units is from an unsupported
lot number.
Replace the unsupported Fiber Amplifier Units with those
from supported lot numbers. (Refer to 1-3-3 Supported
Fiber Amplifier Units.)
The number of Sensors connected is
more than the permissible number.
Connect a number of Sensors that is within the limit.
The reset switch was pressed while
the Mobile Console was connected.
Temporarily disconnect the Mobile Console.
The Unit is faulty.
Replace the Unit.
