0474 SMB and shut off valve with filter

ENGLISH
Safety mode box with shut off valve for CO2 Safety System.
Important!
Retain this instruction manual for future reference: Please read these instructions carefully prior to start-up and use. Failure to follow any of these instructions could void product warranties. LogiCO2 assumes no responsibility for claims arising out of improper or careless use or handling of it's products.

Function
Safety mode box (SMB) with shut off valve is an accessory for the Mk9 and Mk90 CO2 Safety System that shuts off the CO2 gas distribution in case of a leakage. It consists of a magnetic valve, electronics box and cabling. The Shut off valve is designed for usage of CO2 with a pressure of 0,15 to 30 bar or 2,2 to 435 Psi.
SMB has a 1 meter Cat5 cable from the electronics box, with a blue RJ45 connector that is plugged in to the blue alarm signalling output cable side from either the Mk9 or Mk90 CO2 sensors. When the CO2 sensor indicates a high CO2 concentration, the magnetic valve will shut off the CO2 gas distribution. The valve is failsafe (shuts off at power loss).
The magnetic valve should be installed as early as possible in the CO2 gas distribution chain (close to the CO2 tank) in order to avoid possible CO2 leakage before the safety valve.
Install the electronics box in a suitable place where it is mechanically protected. Remove the cover by turning it counterclockwise 1/8 turn to access the mounting screw holes.

Annual function control of the safety valve
Instruction on how to clean the filter, if the SMB shut off valve is fitted with a filter: To test the safefy valve, make sure that the red diode on the valve is on, indicating that the valve is powered on and open. Test the opening and closing of the valve by pressing the red test button on the SMB connection box. The red diode on the valve should turn off and you should hear a clear clicking sound. Please observe that the flow of CO2 must be turned off manually, by closing the emergency shut off valve and verify that there is no gas pressure in the system. This is very important since you are about to open the system to clean the filter. Any debris should be caught inside the filter. By using a socket wrench, carefully remove the filter from the valve and clean it.

After cleaning, make sure that the filtergasket is in place and mount the filter again firmly. Carefully open the emergency shut off valve to allow the flow of CO2 again.
