5. Basic Operating Procedures
5.1 Operating Procedures Using
the Display Unit
Themodicationofdatasettingsfromthedisplayunitcan
be carried out using the three setting switches (infra-
redswitches)-namely,the“
”“ ”and“ ”
switches. The infra-red switches enable the user to set
parameters without opening the cover.
This chapter will provide a description of basic data
congurationandthemethodstobeusedwiththethree
setting switches. This instrument can also be operated
using a handheld BRAIN Terminal (BT200) or a HART
Congurationtool.(RefertoSection5.5foroperationvia
BRAINTerminalorHARTCongrationtool.)
WARNING
Besuretosetparametersas“Protect”onthewrite
protectfunctionafternishofparametersettingwork.
Under extremely rare case, the infra-red switches may
respond unexpectedly in such conditions as sticking
ball of water or extraneous substances on the surface
of display panel glass according to the principle of
infra-red switch operation. Its probability rises in
such cases as sticking rain water by storm or other
similarsituationandwashingupworknearowmeter
installation place.
Either to illuminate or stop illuminating the infra-red
switchesbytheashlightmaycausethemis-reaction.
Refer to Section 6.3 how to use the write protect
function in detail.
IMPORTANT
Operate the display unit under the condition where
direct sunlight, etc... do not shine to the setting
switches directly when the parameter setting operation
is carried out.
NOTE
• Always use the setting switches with the cover
closed.
• Use these switches with them covered by the
glass window.
• If dirt, dust or other substances surfaces on the
display panel glass, wipe them clean with a soft
dry cloth.
• The operation with dirty gloves may cause a switch
response error.
