Initial setup of controller
After the completion of the initial setup of the sensor units, initialize the controller with power on the controller.
Refer to [11. OPERATION] for the operation procedure of the controller from initial setup to run.
Initial setting menu is displayed interactively on the Liquid Crystal Display (LCD).
Please set it up in order.
(1)
Initial setup:
Set the following parameters for conditions of connection of the sensor units using the key switches.
1) Number of engines to be monitored by the controller (1 engine or 2 engines)
2) Number of connected sensor units
3) Sensor units to be excluded from calculation of mean values
(2)
Full-load setting:
By the full load setting during operation of the engine(s) under the maximum load, you can adjust the
maximum mist density during normal engine operation to the standard value (No. 3 on the mist indicator).
The alarm value will be optimized by this setting.
If the full load is not set, the No. 0 mist indicator lamp of each channel will flash.
* About Full load setting
The oil mist concentration in crankcase of a diesel engine varies significantly depending on the difference of
the engine type, each cylinder and operating conditions.
Therefore, normally, the full-load setting is performed based on the maximum mist concentration during
normal operation of the engine, such as the engine running under the maximum load. Some engines might be
occurred between 75% and 100% load, so that “PRE ALARM” is detected at about three times higher mist
concentration and “HIGH ALARM” is detected at about five times higher mist concentration.
The alarm setting values are automatically set the optimal value by the “Full load setting” operation for all
sensor units.
* The full load of the controller is set to the default value before delivery from our plant.
(When the digital value is “100”, the “PRE-ALARM” value will be set to approximately 0.6 mg/L, and the
“HIGH ALARM” value will be set to 1.0 mg/L.)
※
After full load setting of the controller at maximum load, please do the full load setting of the
controller on the operating condition again in case of indicating more than 3
rd
position out of 15
th
position
of the mist indicator on the controller without engine abnormal.
