resideo Z11S Braukmann Reverse rinsing actuator

product

APPLICATION
The Z11S automatic reverse rinsing actuator provides fully automatic cleaning for all Resideo reverse rinsing filters, filter combinations, water supply units and water distributor units. The reverse rinsing intervals are adjustable in sixteen steps between four minutes and three months. The Z11Shas an emergency running function in the event of power failure (only when batteries are fitted) and offers the possibility of manual operation of the reverse rinsing function. Connection options are available for differential pressure switching, remote control and remote monitoring.

SPECIAL FEATURES

Push buttons give easy setting of intervals.
Push button for manual operation of reverse rinsing.
Digital indicator of time interval set.
Digital indicator of number of reverse rinsing cycles carried out
Facility to indicate time remaining before next programmed reverse rinsing cycle
Reset button enables resetting of counter
Settings are maintained even when electrical power fails
Set during manufacture to 45 day interval Can be set to 16 different reverse rinsing intervals Automatic battery 1) run-on if mains supply fails
Manufactured with integral electrical suppression
Additional PG 9 cable entry for connection of remote operation, remote monitoring or differential pressure control Can be connected for differential pressure switch, remote operation or remote monitoring.
Bayonet connection enables fitting without tools.

METHOD OF OPERATION
The Z11Sopens or closes the ball valve according to the set time interval. The opening of the ball valve causes a differential pressure within the filter which activates the reverse rinsing function. The ball valve closes again at the end of the reverse rinsing period. Four batteries (not supplied) provide back-up protection. The batteries close the ball valve if power fails during reverse rinsing function, thus preventing unwanted water loss.
REVERSE RINSING
Reverse rinsing duration when mains electrical operation approximately 25 sec. Reverse rinsing quantity at 4.0 bar operating pressure.

INSTALLATION GUIDELINES

Setup requirements

In case the mains supply fails during the backwash the batteries (if they are fitted) provide the energy for closing the backwash ball valve. The battery charge should be checked regularly. At the latest after two years exchange the batteries with new ones.
In order to avoid flooding, it is recommended to arrange a permanent, professionally dimensioned wastewater connection.

Additional connection options The Z11S can be remotely actuated by:

A volt-free switching circuit
Via an open-collector output In both cases the minimum holding period is one second. Reverse rinsing occurs when the inputs “Start” and “U+” have been separated. The reverse rinsing function can be actuated according to demand using the DDS76 differential pressure switch with voltage free switching. It is recommended that the differential pressure be set to 1.0 bar. Operation occurs when the inputs “Start” and “U+” have been separated, that is, after the differential pressure has fallen below the set value. Through this it is guaranteed that a maximum quantity of water is available for reverse rinsing. If reverse rinsing starts immediately irrespective of the duration of the differential pressure signal, then the inputs should be connected instead to “U+” and “SIGN”. The DDS76 differential pressure switch can only be used where Z11S and F76S fine filters are also installed. For remote monitoring of the open/closed position of the ball valve the installation of a building management system with 0 to 10 V input is recommended. The maximum current is 10 mA. With a current of 0.5 V the ball valve is open and with a value between 5 V and 6 V the ball valve is closed.
