Wormhole detectors will automatically try and detect the forming of new wormholes while installed on ships, stations or planets / moons. You can also order an active scan of a star. Active scan will take 60 minutes, and if the ship moves out of the star system, the active scan will be canceled.
I cannot order an active scan from my station.
I get this message:
"This ship does not have any active Wormhole Detector modules!
Make sure the WHD modules have personnel and are installed on the ship."
