Samsung E201 Error Help

[C_HVAC_S]

Require some help with a U200 E201 fault on a Samsung DVM S2.
Outdoor Unit Model: AM140AXVGGR/EU.
Indoor Unit Model: AM071ANMPKH/EU.

I have 6 indoor units and 1 branch box connected to the system.
The outdoor unit as been programmed to 6 indoor connected and cycles through the address on the segment display.
Error occurs about 5 mins of operation.

Checked power supply to all indoor units and checked interconnecting voltage.
No visible signs of damage to cable either.
Have noticed that LED 302 is lit on 3 of the units. Unable to find any info on the function of this LED.

Any help would be appreciated.
