(10) Version Number Display
Select function code "E" in <MAINT.> mode, then the converter-incorporated ROM version
number is displayed.
(11) Entry of Password for Transferring to “Service Mode” (Function
code "F")
Function codes "1." to "F." in <MAINT.> mode are provided as function codes in "service mode"
used when YOKOGAWA performs servicing.
These function codes can be selected by entering the password (77) in function code "F".
However, request servicing by YOKOGAWA as a rule if operations are required in "service
mode".
5.3.4 Key Operations in <PROGRAM.1> Mode
In <PROGRAM.1> mode, setting operation for various data values such as output range can
be performed. Also, selecting operation for various actions such as range selection can be
conducted.
Function code “1” to “F” → Data setting
Function code “1.” to “F.” → Action selection
For specific contents, see Table 5.5.
This subsection describes key operations to be performed by specifying function codes in
<PROGRAM.1> mode and displays accompanying such key operations.
(1) Output range setting (Function code “1”, “2”)
(2) Reference sensitivity setting (Function code “4”)
(3) Applied voltage setting (Function code “5”)
(4) Parameter setting for response checking (Function code “6”, “7”, and ”8”)
(5) Output signal setting in the case of <failure> (Function code “9”)
(6) Line-segment function output setting (Function code “A”)
(7) Concentration upper limit alarm setpoint setting (Function code “b”)
(8) Out-of-sample detection concentration setting (Function code “c”)
(9) Setting averaging coefficient (time constant) (Function code "d")
(10) Range switching (“remote/local”) selection (Function code “1.”, “2.”)
(11) Output mode (“Hold/No Hold”) selection in maintenance (Function code “3.”)
(12) Output signal mode selection in <failure> (Function code “4.”)
(13) Selection of automatic zero calibration function “execution/stop” (Function code “5.”)
(14) Selection of cleaning sequence to be used (Function code “8.”)
(15) Selection of measuring tank cleaning function “execution/stop” (Function code “9.”)
(16) Selection of sand filter cylinder cleaning function “execution/stop” (Function code “A.”)
(17) Selection of out-of-sample detecting function “execution/stop” (Function code “b.”)
(18) Concentration display unit selection (Function code “c.”)
(19) Selection of air pump action function “execution/stop” (Function code “d.”)
(20) Selection of negative (below-zero) display in <MEAS.> mode (Function code “E.”)
(21) Selection of below-4-mA output hold in <MEAS.> mode (Function code “F.”)
(1) Output Range Setting (Function code “1”, “2”)
Analog output signals include “output range-1” and “output range-2”. Either of them can be
arbitrarily output.
