Can be several causes: No current drawn on output channels, a
switchover to emergency power supply net, etc.

Module and outputs OK.
Relay output modules
Capacity
Double-pole relay contacts rated at 8A / 250 VAC. The outputs are fuses in both poles.
2.5A for 230V modules, 4A for 24V modules and 1.25A for modules dedicated for LED
lights. The printed circuit board is designed to fulfill the demands of both max. current
and max. voltage.
On the relay module with current sensing, four relays are grouped together on one
printed circuit board. This means they typically will be used as the relays for main and
spare lanterns. The four relays have a common power supply, selectable out of two
available power supplies.
On the relay module without current sensing, all 8 relays are stand-alone. The 8 relays
have a common, single power feed .
Manual operation
Each output may be individually turned on. This is used in the event of a system failure
and where it is imperative that the outputs are correct ly set.
As soon as one output is set, the hardware will turn all outputs off. This ensures full
control of the outputs in On or Off state.
The relay module without current sensing does not have the option of manual
operation. This is because this particul ar module is not intended to be used with critical
outputs, such as navigational lanterns.
