3.4.25 Conversion setting for disconnection detection (Un\G164,
Un\G165) (Q68TD-G-H02 only)
When disconnection is detected, a value stored into CH Measured temperature value
(Un\G11toUn\G18) is set. (Refer to Section 3.2.2)
The value to be stored is selected from “Up scale”, “Down scale” or “Given value”.
(1) Setting methods
(a) Set the value to be stored into buffer memory.
Figure 3.38 Setting of Conversion setting for disconnection detection (Un\G164, Un\G165)
The value to be stored into CH Measured temperature value (Un\G11toUn\G18)
changes as follows, depending on the setting value.
1) Up scale (0
H)
Up-scale of the range currently set is stored.
2) Down scale (1
H)
Down-scale of the range currently set is stored.
3) Given value (2
H)
The value set in CH Conversion setting value for disconnection detection
(Un\G166toUn\G173) is stored.
(b) Turn on Operating condition setting request (Y9) to activate the setting.
(2) Default value
All channels are set to “Down scale” (1111H).
POINT
If a value out of the setting range is set, the module operates with the default
setting, “Down scale”(1
H).
