Detailed instructions for use are in the User's Guide.

[. . . ] The meter can be conveniently read from a single line sevendigit display with units and symbols. A pushbutton provides user friendly control of the various display loops. All failures and faults are recorded automatically and displayed on the LCD screen. To protect the reading data, all relevant data is saved in a non-volatile memory (EEPROM). [. . . ] Also two accounting days are available for both inputs. Pulse Output The meter provides levels for two optional external pulse outputs, which can be freely programmed using the HYDROSET software. Possible pulse output values · Energy (standard setting) · Volume (standard setting) · Tariff energy 1 · Tariff energy 2 · Tariff condition 1, limit switch · Tariff condition 2, limit switch Honeywell Subject to change 3 Monthly Memory The EW773 Series has a history memory of 24 months. The following values are stored in the EEPROM on the programmed date 1. . . 31 of the actual month: · Date / Time · Volume · Energy · Error day counter · Maximum monthly flow rate · Maximum monthly power · Date of maximum monthly flow rate · Date of maximum monthly power · Tariff energy 1 · Tariff energy 2 · Tariff definition 1 · Tariff definition 2 · Impulse counter 1 · Impulse counter 2 EN0H-2600GE25 R1209 EW773 SERIES ULTRASONIC HYDRONIC METERS Log Memory The log memory is used to store consumption values. The storage frequency can be selected from various storage intervals (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 minutes or the default setting of 24 hours, see Table 1). The data saved in the log memory can be used for the following analyses: · Reading the meter on a certain day · Example: if the day for reasing is 01. 10 (1 October), the meter reading is displayed for the period from 01. 10 of the previous year to 30. 09 of the current year. · Comparison of the last consumption period with the preceding period Table 1. Extract of possible log memory settings Storage interval Number of data records 5 minutes Error status, overload 440 15 minutes time temperature, 440 overload time flow rate, 440 1 hour forward temperature, 24 hours 440 return temperature, date and time, energy, tariff energy 1, tariff energy 2, tariff definition 1, tariff definition 2, volume, error day counter Values Recording period 36. 6 hours 110 hours 18. 3 days 440 days Tariff Function The integrator offers two optional tariff memories for monitoring plant load states for limit tariffs. Extensive tariff conditions make it possible to adapte the meter individually to the required customer-specific applications. Apart from the energy a timebased tariff can also be programmed. The following limit types are possible (this example applies to the display with 3 decimal places): Table 2. 25 500 l/h LIMIT resolution 1 °C 1 °C 1 kW 100 l/h P Q Display Control The readings are displayed on the meter by a 7-digit LCD with units and symbols Loop Structure The EW773 Series display has six loops. Some display windows consist of two (to maximum seven) displays that are shown alternately at 4-second intervals. Some pictures in the loops can be deactivated separately. NOTE: For quick visual guidance, the loops in the display are numbered from 1 to 6. Maximum Values The integrator creates max. values for power and flow rate based on consumption time, which are stored in the EEPROM. The integration intervals are adjustable to 6, 15, 30 or 60 minutes. Default setting is 60 minutes. The main loop with the current data, e. g. for energy, volume and flow rate, is programmed as default setting.
