4.4.2 Using the Configuration Tool
This method is applicable only to the model
EJX110B.
With a configuration tool, you can change which
process connection is used as the high-pressure
side without mechanically rotating the pressure-
detector section 180 as described in subsection
4.4.1. To change, call up the ‘H/L_SWAP’ parameter
and select REVERSE (right side: low pressure; left
side: high pressure) or select NORMAL to change
back to normal (right side: high pressure; left side:
low pressure).

Input/Output Relationship
IMPORTANT
Since the H/L label plate on the capsule
assembly will remain unchanged, use this
function only when you cannot switch the
impulse piping. If the ‘H/L_SWAP’ parameter
setting is changed, the input/output relationship
is reversed as shown in Figure 4.6; be sure this
is understood by all. After reversing the setting,
modify the H/L label plate to clearly indicate this
change.
4.5 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.
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.
