Operating status menu on the PCB display
The LC display on the PCB is used to display status
information and operating values. Buttons S3, S4 and S5
are used for menu control.
switched, output 'Q9 Alarm2' is switched off, and output
'Q10 Sys error' and output 'Q15 Functional test error' are set.
The next functional test is only possible after reset.
Smoke detection
Normal operation
During normal operation 'bS OK' is displayed.
Preselection
Preselecting fire dampers (FD1 to FD6)
Use button S2
to select the number of connected fire
dampers (FD 1 to FD 6). The selected value will be set once
you switch on the control (power on). Subsequent changes
using S2 will not affect the control. If you enter a wrong value,
e.g. S2 = 0 or >6, error message 'ErrorS2' will be displayed,
and 'Q10 Sys error' will be set. Connect the dampers
according to the wiring diagram in ascending order, starting
with FD1 (FD1, FD2…FD6).
Initialisation
During initialisation, e.g. after switching on the control, 'bS
Init' is displayed. 'bS Init' remains displayed until all fire
dampers are open. After about 145 s, 'bS OK' is displayed.
During initialisation, output 'Q6 Initialisation active' is set.
The system is released 10 s after all fire dampers have been
opened. Output 'Q12 No fire damper is closed' is switched.
During this phase no operation is possible using the display.
During initialisation, the running time for opening the fire
damper is being monitored. If a fire damper fails to open
within the set period of time, this fire damper is closed, and a
message is displayed. Output 'Q12 No fire damper is closed'
remains switched off, and output 'Q9 Alarm 2' is switched off.
Functional test / monitoring of the running time
The functional test for the fire dampers is started on input I14
(positive edge ↑ ), either by pressing a button or due to a
signal from a higher-level system. During the test, 'bS tESt'
is displayed, and output 'Q14 Functional test is active' is set.
Output 'Q12 No fire damper is closed' is switched off. The
functional test is interrupted only in the event of a fire (fire
damper closes) or when smoke is detected and signalled to
input 'I12 SD 1 Smoke'. The closure time (25 s) and opening
time (145 s) for the fire damper is monitored also during the
functional test. If a fire damper fails to open or close during
the set period of time, the fire damper is closed and
displayed. Output 'Q12 No fire damper is closed' is not
If smoke is detected and signalled to input 'I12 RM 1 smoke',
the message 'rAuch' is displayed, all fire dampers close, 'Q8
Alarm 1' is switched off, and 'Q13 Smoke' is set. If the duct
smoke detector is contaminated, signal at input 'I13 RM 1
Contamination', the message 'SchmutZ' is displayed,
'Q10 Sys error' is set, and 'Q9 Alarm 2' is switched off.
Error messages
The following error messages may be displayed:
Error when opening (FEauF) fire damper bS1…bS6, running
time error during initialisation and functional testing.
'FeaufbS1' 'FeaufbS2' 'FeaufbS3' 'FeaufbS4' 'FeaufbS5'
'FeaufbS6'. If during initialisation or functional testing a fire
damper fails to open within 145 s, the fire damper is closed,
an error message is displayed, and output 'Q9 Alarm 2' is
switched off.
Error when closing (FE Zu) fire damper bS1…bS6, running
time error 'FE ZubS1' 'FE ZubS2' 'FE ZubS3' 'FE ZubS4' 'FE
ZubS5' 'FE ZubS6'
If during functional testing a fire damper fails to close within
25 s, the fire damper is closed, an error message is
displayed, and output 'Q9 Alarm 2' is switched off.
