Rotating Transmitter Section
The transmitter section can be rotated in 90° segments.
1) Remove the two Allen screws that fasten the
transmitter section and capsule assembly, using the
Allen wrench. Also, remove the pipe for EJA530A
with Measurement span code A, B, and C, using the
slotted screwdriver.
2) Rotate the transmitter section slowly in 90° segments.
3) Tighten the two Allen screws to a torque of 5 N·m.
IMPORTANT
Do not rotate the transmitter section more than 180°.

Integral Indicator
An integral indicator can be rotated as shown in Figure
3.11.
IMPORTANT
The terminal box cover is locked by an Allen head
bolt (a shrouding bolt) on CENELEC and IECEx
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 by hand.
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) Supporting the integral indicator by 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.
