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 shall not be replaced. The main board 5010
shall be replaced, since more components are broken 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
stored.
If the stored value is below 100 mA, this fault will later be generated
for a measured current higher than the stored value plus 20mA.
(One example: 75 mA (stored) + 20mA = 95 mA = fault limit.)
If the stored value is over 100 mA, this fault will later be generated for
a measured current higher than the stored value plus 20%.
(One example: 150 mA (stored) + 20% = 180 mA = 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.
Check connections etc.
FAULT: High current consumption, control
unit xx
The control unit current consumption is > 3.3A (> 6.3A in alarm state)
and because of this, the battery charging is turned off and will be so
until the current consumption has decreased to < 3.3A (< 6.3 A) again.
FAULT: Interlocking input AAA-PP
An interlocking input is not activated within the time set for fault
activation (5-255 seconds). The time is counted from the activation of
the output in the interlocking combination, area AAA / point PP.
FAULT: Internal short circuit, COM-loop x
control unit xx
Short-circuit on the connection (ribbon cable) to or between the
