4.3 Rotating Transmitter Section
WARNING
Intrinsic safe type transmitters must be, as a rule,
do not rotate transmitter section if it is powered.
In case you need to rotate when the transmitter
is powered, using gas detector and confirm no
existence of explosive gas before rotating.
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 five 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. For the EJX530B
whose capsule code is A, B or C, the pipe of
the atmospheric opening may interfere with
the stopper and disturb further rotation. In that
case, screw off the pipe first, rotate the housing,
and then screw in the pipe by hand again.
3) Tighten the five setscrews to a torque of 1.5
N·m.
IMPORTANT
Do not rotate the transmitter section more than
the above limit.
