Description
The internal RAM
failed.
This failure can occur
any time. During
failure, the D9068
continuously cycles
through its
start-up routine. Each
time the start-up
routine takes place,
the SYS TROUBLE LED
flashes two times.

The external RAM
failed.
This failure can occur
any time. During
failure, the D9068
continuously cycles
through its start-up
routine. Each time the
start-up routine takes
place, the SYS TROUBLE
LED flashes three
times.

The ROM checksum
failed.
This failure can occur
at any time. During
failure, the D9068
continuously cycles
through its start-up
routine. Each time the
start-up routine
occurs, the SYS
TROUBLE LED flashes
four times.

An EEPROM Test is
performed every 10
minutes. If the
checksum fails, the
D9068 automatically
defaults. The SYS
TROUBLE LED
illuminates and
TROUBLE PROGRAMMING
appears on the keypad.

The D9068 considers the
D7033/FMR-DACT-KEYPAD Keypad
Programmer connection as an
abnormal condition.
A.2

Input Points

When a problem exists with the D9068's
input points, the Sys Trouble LED
remains steady on. If the input point(s)
are programmed for supervision, plug in
the D7033/FMR-DACT-KEYPAD Keypad
Programmer and press [1] to select 1:
STATUS from the Main Menu. If the status
shows any point troubles, check the
input point wiring and verify that all
EOL resistors, if attached, are intact.
Refer to Section 4.2 Input Point
Operation on page 25 for additional
information.
A.3

Trouble Relay

When powered up, the D9068's on-board
trouble relay is energized (normal
standby). Refer to Figure 12 and
Figure 13 on page 16. When the on-board
trouble relay remains in the off-normal
(de-energized) position, check the
trouble relay's programming
configuration.
Releas on Trbl: This setting, Release on
Trouble, keeps the trouble relay
activated and releases it to indicate a
trouble condition.
Activ Gnd Strt: This setting, Activate
on Ground Start, keeps the trouble relay
deactivated and activates it when the
D9068 needs to place a call.
If the FACP supervises the connection to
the D9068's on-board trouble relay and a
wiring fault occurs or the EOL resistor
is missing, the FACP shows a system
trouble condition on the appropriate
D9068 input point (if it is used and
programmed). The D9068 sends a System
Trouble Report. The Sys Trouble LED and
on-board trouble relay on the D9068 do
not activate.
You must reprogram all
configuration
settings.

often, contact Bosch
