Be sure to confirm the items below.
Check and make sure the installation, piping, wiring, terminal base connection, and water pressure (0.03 MPa or higher at the sample water
inlet) once more.
If the sample water pressure of 0.03 MPa or higher cannot be obtained at the sample water inlet, you can perform simple test operation of the
oil concentration detector. See "5-1 Test operation method by the Manual Operation." (The electromagnetic valve for sample water opens
during test operation. Provide a valve before the sample water inlet to close the sample water line from the bilge pump.)
Test operation method by the Manual operation function
5-1.
Prepare mineral water.
The upper lid and the drain valve are opened and closed. They must be closed firmly when closed.
Close the valve provided before the sample water inlet.
Use the Manual Operation function to test-operation the oil concentration detector after installing and constructing it or in the
following cases:
when the bilge separator is disabled but you want to execute an alarm operation test including three-way valve output signals.
when a pressure of 0.03 MPa or higher cannot be applied to the sample water inlet
The Manual Operation enables you the following:
The manual operation is implemented for 5 minutes independently of the setting state of the pressure switch. When the manual operation
ends, "Main Menu" returns. And then the oil concentration detector enters the standby state.
The alarm operation test can be executed when the concentration is less than the specified oil alarm point during manual operation.
Manual test operation procedure
Press "Enter" for 2 seconds or longer. The alarm test starts. (Continued to the next page.)
Make sure the oil concentration detector is in the standby state. ("Standby" and the current time
are displayed on the screen portion of the oil concentration detector.)
Close the valve provided before the sample water inlet.
Open the upper lid of the sensor unit and the drain valve to empty the sensor unit. Close the
drain valve and feed mineral water into the detection tube (to about 80% of the detection tube)
from the top of the sensor unit (from which the upper lid is removed), and close the upper lid.
Keep on pressing "Esc" for two seconds longer in the standby state. Enter "Main Menu."
Press " " twice. "Test Mode" is displayed under "Main Menu."
Press "Enter." A screen appears to select respective TEST function items.
"Manual running" is displayed to execute the manual operation.
Press "Enter."
This screen is displayed for about 5 seconds and the manual operation starts.
"Warming up " is displayed on the bottom line of the screen.
The remaining time (in seconds) is displayed to the right side of "Warming up."
(Press "Esc" for 5 seconds or longer to stop the manual operation halfway.)
Shows an oil concentration during operation. This screen shows the state of the three-way valve
output signal and the measured oil concentration.
When the oil concentration is less than the oil alarm point (when "Alarm" is not output), you can
execute an alarm test including the three-way valve output signal.
