2.2.14 Day/night control & weekday control
The ASD 532 can be adapted to operational processes (e.g. if dust, vapour and/or smoke are produced during working hours)
using the day/night control. When the day/night control is activated along with the required weekdays, different trigger thresh-
olds, pre-signal allocations (smoke level only, not relays) or
LS-Ü parameters can be assigned for each time slot (see Sec.
2.2.13).
Warning
Improper parameter changes in day/night operation may result in non-compliance with the EN 54-20 norm.
Notice
•
Day/night control can be used only via the “ASD Config” configuration software.
•
Day/night control is effective only on the activated weekdays (“ASD Config”) and in switch positions X01 –
X03 .
•
On non-activated days of the week, night mode of operation is always selected.
•
In addition to the watchdog indicator (flashing point in the left segment display), the point is also continuously
lit on the right segment display whenever the day/night control is active (only with the selected switch posi-
tions
X01 – X03 ) .
2.2.15 Fault triggering
If a fault occurs on the ASD 532, the “Fault” relay is de-energised and the “ Fault ” display is activated. In the event of a fault the
fault profile can also be localised using the event code display on the AMB 32 (switch position E ) (see also Sec. 8.5.4.3 and
10.3.1). The following events trigger a fault (list is incomplete):
•
Fault: airflow (after expiry of LS delay time)
•
Fault: fan (fan limit data exceeded or fallen short of, tacho signal)
•
Initial reset fault
•
Fault: smoke sensor dusty / dirty
•
Fault: smoke sensor missing; communication disrupted; other
•
AMB 32 communication fault to XLM 35 / RIM 36 / SIM 35 (individual)
•
Emergency fault (microcontroller failure)
•
Undervoltage fault (13.9 VDC, +0 / -0.3 V)
•
Fault: power supply (no voltage on the ASD, no “ Fault ” display)
•
ASD inactive via “External reset” input.
Notice
The “Fault” relay has picked up in the release state

contact Te. 12/10 closed, 12/11 open (ASD 532 under
voltage; no fault event present).
2.2.16 Event memory
The ASD 532 has an event memory capable of storing up to 1,000 events. The latest (i.e. most recent) event is always placed
in the first position. If the memory exceeds 1,000 events, the oldest event is deleted. The event memory as a whole can be de-
leted only by the manufacturer. The event memory can be read out directly on the ASD 532 using the rotary switch function
(switch position
E = last 99 events, see Sec. 8.5.3) or using the “ASD Config” configuration software (up to 1,000 events can
be selected).
