Continued from the preceding page. (Manual test-operation procedure)
When the alarm test starts, the oil concentration detector artificially increases the oil concentration
to enable the alarm test. "sim" appears in the center of the top line of the screen.
The ppm value "x" is increased by one each time you press " ." (You can reduce the value
similarly by pressing " " but cannot reduce the value under the current measured concentration
value.) When the measured oil concentration exceeds the oil alarm point (Alarm1 and Alarm2),
the oil concentration detector enters the alarm state and turns off the three-way valve output
signal.You can confirm the alarm operation. Both AL1 and AL2 lamps blink. The alarm test is
disabled when the oil concentration of the sample water goes over the oil alarm point in the test.)
Press "Esc" after confirming the alarm test.
About 5 minuites later with "Esc" unpressed, "sim" disappears from the screen.
The operation ends. "Main Menu" returns. And then the oil concentration detector enters the
standby state.
"sim" disappears and "Manual running" returns.
This screen shows the ON/OFF state of the three-way valve output signal and the measured oil
concentration. Press "Esc" for 2 seconds and unpress it.
The operation ends and the oil concentration detector enters the washing state.
The remaining time (in seconds) is displayed to the right of "Washing."
When the washing operation ends, the oil concentration detector waits for judgment of whether
the inside of the detection tube is clean.
"Wait Stable" appears and the remaining time (in seconds) is displayed to the right of "Wait
Stable."
After the washing operation ends, "TEST Mode" appears to select "Manual running" of the TEST
function. Press "Esc"
"Main Menu" returns. Press "Esc."
"Standby" returns.
With this, the test operation by the Manual Operation ends.
