Problem after power failure

After an electrical power break on the bus the 4 contacts of one VMB4RYNO are closed of a short time (puls).
I have several of these modules, but my dooropener is connected to this one. I do not like to re-cable the system,so is there a way of solving this problem.
When I have a power failure (it has happend some time ago) and the power comes up again, my front door is opened!



A relay module will not close its relays, unless a command has been given to do so.
Please check your configuration.
It is possible that due to a programming conflict of an initiator, the relays receive an on command, immediately followed by an off command.
This can cause this behaviour at power-on.
