FAULT: Wrong type of unit no. xxxxxx
The output unit is not the same type as programmed. Change the
programming
or
the output unit.
High Current loop x, BS4-board x, CU xx
(BS4=1584, Autronica interface board)
The current consumption is >60 mA on the BS4 loop.
High Voltage on BS4-Board x, CU xx
(BS4=1584, Autronica interface board)
The BS4 loop voltage is >16V (normally it is 14V ±0.1V).
No connection loop x, BS4-Board x, CU xx
(BS4=1584, Autronica interface board)
Cut-off (break) on the BS4 loop. This is indicating a single break on
the loop. Communication has to be performed in both directions, to
find all units.
Each 10 minutes an attempt is made to comm. in one direction again.
Short circuit loop x, BS4-Board x, CU xx
(BS4=1584, Autronica interface board)
Short circuit, or current consumption >167mA, on the BS4 loop
(
short circuit isolator
is not connected on the loop
). Check the loop
NOTE! As long as there is a short circuit, the BS4 loop is disabled.
Each 10 minutes an attempt is made to re-enable the loop again.
