Connecting Fiber Amplifier Units Section 1-3
1-3-5 Power Supply for Sensors
The Communication Unit supplies power to the Fiber Amplifier Units. The fol-
lowing table shows the methods used to supply power to the Communication
Unit and all Fiber Amplifier Units connected to it.
1-3-6 Registering the Number of Sensors
To detect whether communications with Fiber Amplifier Units are normal, the
number of Fiber Amplifier Units connected must be registered. When the
number of Fiber Amplifier Units connected is registered, errors can be
detected when there is no optical communications response from Sensors
due to malfunctions in Fiber Amplifier Units. The errors can be detected by the
difference between the number of Fiber Amplifier Units communicating and
the number registered as connected.
A difference between the number of Fiber Amplifier Units connected and the
number of registered Units is indicated as follows:
• The SS indicator lights red.
• The Sensor Communications Error Flag turns ON.
The following table shows the method used to set the number of Sensors con-
nected to the Unit
Note Fiber Amplifier Units that are allocated two unit numbers (E3X-DA6TW, E3X-
DA8TW) must be counted as two Units when counting the number Sensors.
1-3-7 Sensor Reset Switch
The sensor reset switch is used to replace or add Fiber Amplifier Units without
turning OFF power to the Fiber Amplifier Sensor Communication Unit.
With the Fiber Amplifier Sensor Communication Unit power ON, replace or
perform required work on the Fiber Amplifier Units. After completing work,
press the reset switch to reset all Fiber Amplifier Units and restart normal
communications between the Fiber Amplifier Sensor Communication Unit and
Fiber Amplifier Units.
