    Chapter 1 Start Here… Congratulations on your purchase of a Pulsar Ultra Twin. This quality system has been developed over many years and represents the latest in high technology ultrasonic level measurement and control. It has been designed to give you years of trouble free performance, and a few minutes spent reading this operating manual will ensure that your installation is as simple as possible.

  • Page 10: About The Ultra Twin

    Ultra Twin sends a transmit pulse to the transducer(s), which emits an ultrasonic pulse perpendicular to the transducer face, and the returned echo is sent back to the Ultra Twin. The time taken to receive the echo is measured and the distance from the transducer face to the surface being monitored is calculated.
  • Page 11 PLC, to monitor level space, distance, volume, OCM head or flow (dependant on the application chosen), independently from that shown on the display. There is an RS232 port, so that the Ultra Twin can be operated remotely by a PC or other equipment.

  • Page 140: Digital Inputs

    Digital Inputs About Digital Inputs The digital inputs are used to provide the Twin with information on the operational status and condition of pumps, valves, and other process control devices. Based on the information supplied, by the inputs, the Twin, will make intelligent decisions and modify its control regime to meet the demand of the prevailing operational requirements.

  • Page 142 Device Fail The digital inputs are used to indicate a ‘fail’ situation which effect devices, which are connected to the relay outputs of the Twin, e.g. failure of a pump, screen, valve, etc. This information is then used to initiate changes to the Twins control regime to meet the demands of the situation.
  • Page 143 The decision on whether or not to attempt to start the failed pump on subsequent pump cycles will be determined by P*300 Max. Attempts. Once the number of attempts stipulated have been made the pump will be put out of service until such time the Device Fail input is cleared by a Reset (P*391 = 4) on Digital Input 7.
