Public
Cumulative energy will be displayed as ‘NOT AVAILABLE’ either on communication failure with the power meter
or if power meter setting is set to ‘Fixed’ or ‘Analogue’.
5.9 Communication
Censeo communicates through three channels – one is used for communicating with power meter while the
remaining two are used to communicate with a PC. Of these two channels, one is used for configuring Censeo
on PACT while the other is used to transfer real time pump/ hydro-turbine/ blower performance data on RS485
to the software on the computer.
Censeo communicates with the power meter on RS485 through wired connection. Communication with a power
meter including the baud rate can be configured through Pump Test 9.
5.10 Alarms and Events
Up to eight alarms can be configured for parameters available in Table 2. For each alarm, a maximum of 20
events can be logged compartment-wise in a rollover mode – that makes a total of 160 events. Note that display
and relay indication for alarms would only be configurable through respective display and relay sections in the
software.
Note:
The alarm persistence time for pump/ hydro-turbine/ blower parameters like differential temperature, flow
rate, suction/ inlet temperature, efficiency etc. may vary from persistence time configured by Pump Test9 based
on ‘filter value’ (i.e. averaging period) and the ‘parameter value’s difference with the defined limit at the time of
event’, this is in view of slow varying nature of thermal parameters like temperature in pump/ hydro-turbine/
blower and to avoid false alarms.
5.11 Relays
Censeo can drive two latching relays towards control applications. Relays can be used to either indicate
occurrence of an alarm or to schedule the operation of a pump/ hydro-turbine/ blower.
5.12 Data Storage
Up to 600 parameter days of data with 15 minute DIP can be stored in Censeo memory. The parameters logged
will be configurable, and a maximum of 15 parameters can be selected.
5.13 Time Management
Censeo maintains time with a resolution of one second. Time and date in Censeo can be configured through
Pump Test 9.
5.14 Security
Information from, and transactions with, Censeo are secured with the help of keys.
Pump Test 9 needs to know information related to keys in order to communicate with Censeo. The customer
specific add-on keys (if provided along with the product key) must be added into Pump Test 9 software. (refer to
Pump Test 9 help for details)
5.15 Transactions
Besides collecting and sending out pump/ hydro-turbine/ blower performance data, Censeo also supports
transactions such as time set, configuration download, reset transactions, clearing away historical data sets,
reconfiguration of calibration constants, display configuration, etc.
Censeo maintains a record of last 100 transactions with time stamp in a rollover manner.
