Hi Chiu I have an issue with Zone 11 on my system it comes up with Zone trouble no matter what type of "Zone Type" is attributed to it, to stop zone trouble "Zone Type" has to be left blank. It reports trouble even when the contact is completly disconected from the zone (ie nothing attached). I have also changed the shunt in case of oxidisation to no avail, there is no voltage to the zone and all that has been used is a simple reed contact, this also applies to zone 12. The LEM that is installed has only recently been installed (last 6 months). All firmware is up to date and also I used the latest version of Comfigurator and I also tried using a older version of Comfigurator. Do you have any suggestions as to what else I maybe able to try to rectify issue |

Shift the shunt to the position nearer to the terminal block. Without wires connected to the Zone, shorting and opening the zone should not give zone trouble. If there is zone trouble the lem is faulty see http://www.comfortforums.com/forum77/2273.html What is the meaning of Zine Trouble Last edited on Wednesday Apr 15th, 2020 04:45 am by slychiu |

Thanks for that it looks likely that it is a faulty Lem the shunts are all set in the forward position (non eol) |
