A5.4.4. Disconnecting a Sensor optical fiber
Follow the procedure below to disconnect the optical connector of a sensor optical fiber
from the optical output connector of the DTSX3000
Disconnection Procedure:
1. Stop the operation of the DTSX3000.
Always ensure that no measurement is in progress before disconnecting a sensor
optical fiber.
2. Have on hand a protective cap for the optical output connector of the DTSX3000 to
be disconnected.
The protective cap that was previously removed and stored when the optical fiber
was connected to the DTSX3000 may be reused.
If the protective cap has been stored in a dusty place or stored for a prolonged
period, it must be cleaned to remove any dust which might have collected in the
cap.
3. In reverse order of the connection procedure, unlock the optical connector of
optical fiber, and pull it away from the optical output connector on the DTSX3000
perpendicularly to the panel face of the DTSX3000.
For the E2000/APC optical connector, press down on its lever to unlock it. Then,
hold it with your two fingers and pull it lightly towards you (see the Figure below).
If the optical connector is not unlocked properly, it will not come off easily. Do not
disengage the connector forcibly in this state or it may be damaged. To unlock it
properly, press down the lever completely.
When pulling the optical connector towards you, do so perpendicularly to the panel
face of the DTSX3000. Otherwise, it may not come off easily. Moreover, when
disconnecting the optical fiber, hold its optical connector but never the optical fiber
itself.
4. Put a protective cap on the optical output connector on the DTSX3000.
5. These instructions apply similarly to disconnection from the DTOS2L, DTOS4L, or
DTOS16L optical switch.
For easier disconnection from the DTOS4L or DTOS16L, which has many optical
connectors, detach optical fibers from outer connectors before inner connectors,
and if necessary, temporarily detach existing optical fibers from outer connectors
and re-attach the optical fibers after detaching optical fibers from the inner
connectors.
