FAQ

How much is the life span of the fan?

Sensor of MD-SX detects oil mist using a natural convection system. It does not carry a running gear, therefore the risk of failure is reduced. The life span of its spare parts had improved much better for easy maintenance.

Is sensor required to get exchanged regularly?

Regular exchange is unnecessary. The sensor has a self-diagnostic function, when detection sensitivity falls, and it is judged as it is unusual, the FAILURE lamp of controller turns on. Since dirt is the cause in many cases, cleaning liquid can be used to wash it off.

How is the setting value of alarm decided?

Since the oil mist density changes according to the environment, such as the place which sensor is installed, and the characteristic of diesel engine and so on. In MD-SX series, the setting value of each sensor is set up automatically at the time of initial setting of controller. The alarm value is set up automatically and it can be checked by LCD of controller at any time.

Is it possible to change the setting value of alarm?

The alarm can be setup in two levels, HIGH and LOW with MD-SW series, however it cannot be set up manually. When the full load value is set up manually, the setting value of HIGH and LOW will be assigned automatically.

How much is the sensitivity of sensor?

The minimum detection level is 0.002 mg/l. Change of the level at the operation can be seen clearly when the engine is on or off.

How quick is the response of sensor?

less than 1 sec

Is it approved by classification society?

MD-SX has an official approval of NK, GL, LR, BV, DNV, CCS, KR, LINA, and CR. MD-SX II has an official approval of NK, GL, BV, DNV, CCS, and KR. If you would like to know about other approval of classification society, please contact us.

Is it possible to use one controller of MD-SX for two sets of engines?

Yes, it can be used, however, one controller is required for one engine by regulation of classification society. Please contact us for more information.

Is it possible to use controller of MD-SXII for low speed 2stroke engine?

No, it cannot be used. Please contact us for more information.

Is it possible to use MD-SX for gas fuel engine?

Yes, it can be used. MD-SX series has a good track record with many gas fuel engines.

Is it possible to output analog signal from the controller?

There is an analog output unit as an optional part. Please contact us for more information.

Does a controller have a data log function?

There is a pocket memo which can record data log to CF card as an optional part.

Is there any communication function which connects with AMS of engine control room?

There are three methods. Please contact us for more information.

  1. RS422
  2. WiFi (option)
  3. analog output init (option)

Is it possible to install the controller inside engine?

Yes, it is possible. There is a bracket attachment for anti-vibration means.
