BEP Gas Detector 600-GDL with Control

The BEP Marine 600-GDL Gas Detector uses microprocessor control to maintain accurate sensor sensitivity. It is capable of controlling two sensors that detect both LPG and petrol, and provides both visual and audible alarms. A built-in test switch allows users to verify sensor operation, while indicator lights assist with fault detection.

The 600-GDL model includes all the features of the 600-GD, with the added functionality of switching a valve on and off. It also incorporates a “pulse and hold” feature, enabling the solenoid valve to open using full power and then reducing power to maintain the valve in the open position. This helps minimize power consumption and reduces heat generation while the valve remains active.

Features

• Self testing capability
• Microprocessor control
• Dual sensor capability
• Provision for an external alarm
• Provision for automatic bilge blower switching
• Automatic shut-off solenoid control with Pulse and Hold circuit technology for low power draw(600-GDL only)
• Manual override – Important: Disables gas detector (600-GDL only)

Specifications

• Voltage: 600-GDL 10-15V DC
• Current: Total 350mA Max
• Alarm: 20% LEL (Lower Explosive Limit)
• Current at outputs: 800mA Max (per output)

Note: If you are using a solenoid valve other than BEP’s VR2. The solenoid current draw must be checked to make sure it is 800mA or less at 12.5 volts.

Fault Detection

The nominal alarm point of the 600 series is 20% of the LEL (Lower Explosive Limit) of LPG/CNG in Air. In the event of a gas leak and the alarm activating, close the manual valve on your gas bottles and open hatches to ventilate the area. All fans and blowers used to ventilate must be ignition protected types.

In the event of a sensor being contaminated, damaged, cable shorting or a faulty connection, the amber light will come on for the particular sensor. If the sensor fault persists then the sensor could be damaged and will need to be replaced. In detecting LPG the sensor can also detect hydrocarbons in other products such as cleaners and strong adhesives, this can cause nuisance alarms.

Cautions When Using Gas Sensors

• Exposure to silicone vapors can irreversibly inhibit sensor sensitivity.
• Highly corrosive environments can cause irreversible damage to the sensor.
• Water, freezing, and high-density gas exposure can adversely affect sensor performance.
• The sensor can detect hydrocarbons in other products, causing nuisance alarms.

Important Notes

• If the sensor gets wet, it becomes inoperable and must be replaced.
• For units with S/N before J48494, an 82k resistor must be fitted between terminals G and R on the back of the meter case.
