FAULT: Factory settings, Control Unit xx
The factory settings have been "changed", in Control Unit no. xx, e.g.
because of some external disturbance. The main board has to be
FAULT: Fan xx, technical number xxxxxx
The LED "Fault" is lit on a fan control module connected to Control Unit
xx. Fan no. xx has been triggered but the corresponding I/O unit 3361
input has not been activated within the programmed time.
Check the pressure switch in MSSB and the cables / connections.
Or
The fan phase fault input is activated.
Or
Check Cables / connections.
Note: In the Australian and New Zealand conventions this fault is "not
latched" irrespective of if all other faults are "latched".
FAULT: FB Silence switch, Control Unit xx
Only valid in the New Zealand convention.
New Zealand FB Silence Alarms Bulgin key (outside switch) is turned
on, in Control Unit no. xx, i.e. from not activated to activated state.
FAULT: Fire brigade panel xx, Control Unit xx
FBP=1828 (Ext. Fire Brigade Panel)
The ext. FBP xx, connected to Control Unit no. xx, is programmed as
another type in the SSD or a fault in the unit.
FAULT: Fuse on COM loop x, Control Unit xx
Blown fuse F15 (Loop 0), F16 (Loop 1), F17 (Loop 2) or F14 (Loop 3)
on the main board 5010, in Control Unit no. xx. Fuse T1.6A L 250V
(TR5). Note: The fuse should not be replaced. The main board 5010
shall be replaced, since more components are damaged as well.
FAULT: High current, COM loop X, Control Unit xx
When starting up the Control Unit or when the COM-loop is re-
connected, the loop current in normal condition is measured and the
vlue stored.
If the stored value is below 100 mA this fault will later be generated for
a measured value higher than the stored value plus 20mA.
(an example: 75mA (stored) +20mA = 95mA = fault limit
If the store value is over 100 mA, this fault will later be generated for a
measured current higher than the stored value plus 20%.
(an example: 150mA (stored) + 20% = 180mA = fault limit).
Note! This fault is not checked in alarm condition.
The reason could be not “full” short circuit on the COM loop but very
close to short circuit, e.g. due to moisture / corrosion / bad contact.
FAULT: High current consumption, Control Unit xx
The Control Unit current consumption is > 2.8A (> 6.3A in alarm state)
and because of this, the battery charging is turned off and remains off
until the current consumption has decreased to < 2.8A (< 6.3 A) again.
