
Pressing the right soft key will perform a system test. If the fault clears
after this, monitoring will resume, the message will be cleared, and the
fault relay energized.
After a critical fault occurs, the system will perform a self-test every fifteen
minutes on four occasions to check if the fault has cleared. In the event it is
still present, the self-test will then occur every 24-hours until user
intervention or the fault has cleared.
9.2 System Will Not Power On
Ensure the switched mains supply is turned on and check that the LEDs are
illuminated on the 24Vdc and 12Vdc power supplies. If they are not, check the
mains fuse (fuse 1) and replace if necessary.
Warning Do not remove fuses whilst energised.
If the problem persists, please contact our technical support team at LANDTEC
on (800) 968-2026 or email

9.3 Module Will Not Power On
Ensure there is power to the system by checking that the LEDs are illuminated
on the 24Vdc and 12Vdc power supplies. If they are not, check the mains fuse
(fuse 1) and replace if necessary.
If they are illuminating, it can take up to one minute for the BIOGAS 3000
module to power on. If it does not turn on at the point power to the system is
applied, please wait one minute before pressing any keys on the module.
If after one minute the module has not powered on, check the fuse for the
supply to the module (fuse 2) and replace if necessary.
Finally, check fuse 3, which provides 12Vdc to the Interface PCB, which in turn
supplies the power to the module.
Warning Do not remove fuses while energized.
