BilgMon 488 Oil Content Monitor | Simulation 15ppm Bilge Alarm Test Procedure

Описание: The BilgMon488 bilge alarm has been designed specifically for use in conjunction with 15 ppm oil-water separator units. BilgMon488 performance meets the requirements of the International Maritime Organization specifications for 15 ppm bilge alarms contained in resolution MEPC. 107(49).

BilgMon488 is equipped with 2 adjustable alarms that are triggered when the oil content of the processed sample exceeds the set limit (1–15 ppm, works-adjusted to 15 ppm). Alarm outputs consist of relays and indicator LEDs. Additionally, a 0(4)–20 mA current output signal (corresponding to 0–30 ppm) is available to enable remote surveillance and recording of oil contents.

BilgMon488 consists of two main parts, the MASTER unit (housing with LCD, buttons, and LEDs) and the SENSOR unit (housing with pipe fittings).

The MASTER unit contains all the electronics used for control and data storage of the bilge alarm. Mounted in the lid of the MASTER housing is the main memory containing the bilge alarm log.

The SENSOR unit contains electronics for measuring the sample stream. The SENSOR unit also holds the measurement calibration data. Communication with the MASTER unit is done wireless; hence the SENSOR unit is hermetically sealed and shall not be opened.

Optical sensors monitor the amount of light scattered and absorbed by the oil droplets in the sample stream. Sensor signals are processed by a microprocessor to produce a corresponding oil content (ppm) output. The output is communicated to the MASTER unit, where it is processed. The MASTER unit takes action, such as alarm activation, logging, etc., depending on the oil content and the separator signal.

Zero-point calibration can be re-adjusted on-site, whereas full sensor calibration according to IMO requirements is performed by the manufacturer.

The simulation menu lets the user simulate the PPM input from the sensor unit as well as the separator status input state to verify that the installation of the unit is correct and that it responds as expected to different oil content measurements.

Simulated events will be stored in the log, starting with a SIM_ON event and ended with a SIM_OFF event.

Enter simulation menu:
From the main menu, press ↵.

Leave simulation menu:
Release ↵

Toggle the simulated separator status input:
While still holding ↵, press ↑ to toggle between separator on/off (SEP_ON/SEP_OFF shown in LCD)

Increment/decrement simulated PPM valve:
While holding ↵, press + / - to increment/decrement the simulated PPM valve
