User manual HONEYWELL Z11AS DATASHEET

[. . . ] Z11AS Reverse rinsing actuator for fully automatic filter cleaning Product specification sheet Application The Z11AS automatic reverse rinsing actuator provides fully automatic cleaning for all Honeywell 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 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. Options For filters and filter combinations HS10, F76, F76C, FK76C, FKN76C, FN76C and FN09 (up to 1996). Z11AS-1/2A = 230 V, 50/60 Hz, 10 W with moulded Schuko electrical plug Z11AS-1/2B = 24 V, 50/60 Hz, 10 W without electrical plug Z11AS-1/2Z = 230 V, 50/60 Hz, 10 W with moulded Type 12 electrical plug for Switzerland From 1997 onwards: Use reverse rinsing actuator Z11AS for filters and filter combinations HS10S, F76S, F76CS, FK76CS, FKN76CS, FN76CS and FN09S.

In both cases the minimium 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. [. . . ] 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.
