7.1.2 Notes on Use
CAUTION
Connect the terminal to the connecting hooks in a terminal box or to the relay terminals
on the transmission line, using BT200 communication cable with IC lip, as shown in
Figure 7.1-1.
• All your settings of parameters will be canceled if you turn ULTRA YEWFLO off
less than 30 seconds after the parameter setup. Keep ULTRA YEWFLO turned on
for at least 30 seconds after setting up parameters.
NOTE
<1> With Auto Power-off, the BT200 automatically turns off if it senses no access to
the keys for more than five minutes. This feature does not work, however, if the
parameters described in item 2 below are on the display.
<2> Parameters “A10: FLOW RATE (%),” “A20: FLOW RATE” and “A30: TOTAL,”
when on display, are updated with new data every five seconds.
<3> Use the UPLOAD or DOWNLOAD command when copying the parameters of
one ULTRA YEWFLO to another. Parameters that can be copied are all the items
in the B and C menus shown later in Section 7.4. (Except for B10: TAG NO and
B26: K-FACTOR)
