•
Disconnect the batteries from the control panel (e.g. disconnect the battery
connection cable or F2 fuse). Turn off the mains voltage.
•
The end user, i.e. the last owner, shall hand over worn batteries to the distributor
or appropriate waste treatment plant. This obligation applies to both individual end
users and company end users.
In regard to the control panels, this Operation and Maintenance Manual contains only
basic technical data and information about installation, start-up, maintenance and close-
down. Both the Installer and the User are required to know and apply the complete version
of the “Installation and Operation Manual”, which is provided along with the control panel.
6. SYSTEM EQUIPMENT
6.1.
WRS 2B WEATHER CONTROL PANEL
Required signal is sent by four separate potential-free change-over contacts (output
contacts). The contacts remain active as long as the detector operates, and the contact
minimum operating time is equal to 6 minutes.
WM wind detector and/or RS rain detector are connected to WRS 2b control panel.
As expected, operation is achieved by regulation of the trigger threshold for the signal from
the wind/smoke detector.
Functional capabilities of the control panel (to set) are as follows:
“Limited wind sensitivity” (it is possible to close only if the wind persists).
“Continuous heating” (the rain detector is heated continuously).
“Contact programming” (contacts 3 and 4 optionally switch over during the rain and/or
wind).
“Output inactive” (relays are not energised for the service/maintenance time).
“Close time shortening” (minimum delay in actuators closing is decreased from 6 to
3 minutes).
“Failure” (contact 2 will switch in case of failure of the rain detector).
“Test” (a function that makes it possible to test the detectors and actuators operation).
The active status of the control panel is indicated with a LED: I readiness, W wind
and R rain.
