3.6 Changing the Direction of
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
fl
ameproof 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.
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.
