Rys. 47. Diagrams of connecting actuators to the RWZ 5 control panel
In the RWZ-5 control panel connect subsequent actuators to the following terminals: X1.2,
X1.3, X1.4, depending on the configuration of smoke zones and ventilation zones.
Maintenance
During maintenance activities
– if there are no other local regulations – control all
functions and indicators of the control panel, as well as its components, at least once a
year. This also applies to controlling clamping points, connection cables, indicators and
fuses, as well as possible cleaning of various components.
Check fastening of mounting brackets etc. Possibly lubricate actuators and smoke
extraction devices.
The control panel has a built-
in signal function “maintenance needed”. If this function
is activated, after approx. 11 months of operation, the control panel will inform the user
about required maintenance. After approx. 14 months, the failure massage will be
additionally generated in order to inform about expired maintenance.
The batteries operation should be checked at least once a year.
At 20
°C ambient temperature they should be replaced once per 3 years as a
standard, but not later than after 4 years. Each additional 10
°C of ambient temperature
decreases the battery service time by approx. 1 year!
Charged but disconnected batteries may be stored for approx. 6 months. In case of
extended storage it is necessary to charge the batteries.
As part of the weather module maintenance, the following works must be carried out
at least once a year:
•
Clean rain detectors with a wet cloth, possibly with a mild cleaning agent (do not
scour the detector surface!)
•
Check the smoothness of the anemometer movement
•
Check detectors functioning
•
Check smoke extraction and ventilation devices for proper closing
