Rotating Transmitter Section; Changing The Direction Of Integral Indicator - YOKOGAWA EJX Series User Manual

3.6 Rotating Transmitter Section
The transmitter section can be rotated approximately
360° (180° to either direction or 360° to one direction
from the original position at shipment, depending on the
configuration of the instrument.) It can be fixed at any
angle within above range.
1) Remove the two setscrews that fasten the transmitter
section and capsule assembly, using the Allen
wrench.
2) Rotate the transmitter section slowly and stop it at
designated position.
3) Tighten the two setscrews to a torque of 1.5 N·m.
IMPORTANT
Do not rotate the transmitter section more than the
above limit.

3.7 Changing the Direction of
Integral Indicator
IMPORTANT
Always turn OFF power, release pressure and
remove a transmitter to non-hazardous area before
disassembling and reassmbling an indicator.
An integral indicator can be installed in the following
three directions.

IMPORTANT
The terminal box cover is locked by an Allen head
bolt (a shrouding bolt) on ATEX flameproof type
transmitters. When the shrouding bolt is driven
clockwise by an Allen wrench, it is going in and cover
lock is released, and then the cover can be opened.
When a cover is closed it should be locked by a
shrouding bolt without fail. Tighten the shrouding bolt
to a torque of 0.7 N·m.
1) Remove the cover.
2) While supporting the integral indicator with one hand,
loosen its two mounting screws.
3) Dismount the LCD board assembly from the CPU
assembly. When doing this, carefully pull the LCD
board assembly straight forward so as not to damage
the connector pins between it and the CPU assembly.
4) After rotating the LCD, align both the LCD board
assembly and CPU assembly connectors and engage
them.
5) Insert and tighten the two mounting screws.
6) Replace the cover.
