Control of malfunction notifications and position lights

DOLD flasher relays are used on cranes, wind power systems as well as airfield lighting where they control position lighting. The control of malfunction notifications on machines, lighting, fans, et cetera is an additional task of these devices. Impulse time and pause time are identical with flasher relays.
