Relay K3: device fault alarm and EDS common message

Relay K3 is intended to signal device and connection errors of the

ISOMETER®. In the Master mode with bus address 1, EDS alarm messages can

be collectively indicated by the K3 relay as well as system fault messages. Coll-

ective indication of the EDS alarms by K3 can be disabled by selecting „K3

Alarm: off" from the "EDS Setup" menu. Refer to page 63.

K3 is permanently set to N/C operation, with the contacts 31-34 normally

closed, that means when a fault occurs, the relay deenergizes (K3: 31-32 con-

nected).

Further details are described in "Chapter 3.5.7 Self test". Even when a protocol

converter of the FTC470... series is installed in a BMS system which is tem-

porarily taking over the Master function is, the function collective EDS mes-

sage will remain. This function is directly dependent on BMS address 1, the

Master status is a secondary factor.

The settings for K3 are preset and cannot be adjusted.
