Remote pump stop and start systems for water plants

April 2003 Flow Measurement & Control Surveillance

Omniflex has recently launched a new set of Maxiflex CPUs - the T2. These CPUs are intended for data acquisition and telemetry applications. They require no user programs when used for data acquisition or telemetry application. Simply plug them in; connect field wiring and power up. All I/O is scanned automatically and I/O status assembled into data interchange table (DIT).

The system integrates the remote pump start/stop function with motor status feedback from the pump directly to an annunciator panel. No hard wiring of panel indicator lamps for stop start run indication is necessary. All this information can be displayed on the annunciator via a Modbus link.

The telemetry aspect of the remote control can be implemented on copper cable (screened twisted pair - instrument cables) up to 10 km from the control centre. Radio systems can be used for wireless applications where cable infrastructure is non-existent.

Configuration is easily made using a free Windows based software package called 'OmniSet' and a serial cable available from Omniflex (Figure 1). Simple selection of pull down options allows the user to configure the CPU completely. This configuration includes the ability to create multi-drop telemetry systems using the Omniflex CONET local area network up to 10 km on twisted pair cable (Figure 2).

Maxiflex provides a cost-effective solution to remote control applications and simplifies the field I/O systems by eliminating the need to write time-consuming application programs for data acquisition or telemetry. Should data acquisition be required with the pump control, Maxiflex I/O systems cover analog inputs, voltage, current, thermocouple, RTD and digital inputs, potential free and voltages up to 200 V d.c. - series contact chains and pulse input frequencies up to 50 kHz.
