User manual HONEYWELL Z11S DATASHEET

[. . . ] Z11S Reverse rinsing actuator for fully automatic filter cleaning Product specification sheet Application The Z11S 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. [. . . ] When batteries are fitted, the appliance should not be left unplugged for long periods. www. honeywell. com 73 Z11S Reverse rinsing actuator Method of Operation The Z11S opens 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 actuator close the ball valve again after the end of the reverse rinsing cycle. 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 From 1997 onwards: Use reverse rinsing actuator Z11S for filters and filter combinations HS10S, F76S, F76CS, FK76CS, FKN76CS, FN76CS, FK74C, F74C, FKN74C, FN74C and FN09S. Z11S-A = 230 V, 50/60 Hz, 10 W with moulded Schuko electrical plug Z11S-B = 24 V, 50/60 Hz, 10 W without electrical plug Z11S-Z = 230 V, 50/60 Hz, 10 W with moulded Type 12 electrical plug for Switzerland Additional connection options The Z11S can be remotely actuated by: a) A volt-free switching circuit b) Via an open-collector output. 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. Operation occurs when the inputs "Start" and "U+" have been separated, that is, after the differential pressure has fallen below the set value. [. . . ] 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.
