P/V1500 BLACK INTELLIGENT PUMP General flow performance Free flow: 1200 ml/min Maximum vacuum: -150 mbar Flow can be calibrated to deliver a certain flow at a certain vacuum level. Ask us for more information. Maximum pressure: 350 mbar Maximum vacuum: -350 mbar Free flow: 1200 ml/min Maximum pressure: 150 mbar Figure 1: General flow performance for Xavitech P1500 (left) and V1500 (right) pumps IMPORTANT NOTES Pump Flow: Flow is one-directional, it cannot be reversed Filters: To ensure lifetime, air filters should be used to prevent contaminations like dust to enter the pump Capacitor: Missing...

P/V1500 BLACK INTELLIGENT PUMP Standard models STANDARD MODELS (PART NUMBER) Flex cable Flex cable Flex cable Flex cable LIFE TIME (Hours) ANALOG FLOW CONTROL CONNECTION INTERFACE FREE FLOW (ml/min) PART NUMBER MAXIMUM PRESSURE/ MAXIMUM VACCUM (mbar) Xavitech provides several pre-calibrated standard models. For these models, the voltage and the maximum flow is calibrated to standard values. When buying a standard pump, you still have a few choices you can make. Choose voltage, connection and lifetime. And if you’re pumping agressive gases you can chose Viton or Kalrez membranes. The chart below...

P/V1500 BLACK INTELLIGENT PUMP Electronic interface Inside Pump 2.85 V DC Pull-up Molex 52610 or 52271 or similiar for flex cable Molex 530470510 for 3 or 5-wire connections Note: A VCC capacitor is required for 24-volt pumps * Serial interface applies on pump with flex or 5 wire connection Figure 2: Electronic interface INTERFACE DESCRIPTION Pump Cycle Maximum input voltage: Calibrated voltage + 0.5 V DC. The pump can be damaged otherwise. Minimum input voltage: 5 V DC. However, the pump performance is reduced if the voltage is set lower than calibrated value. Xavitech recommends to always run...

P/V1500 BLACK INTELLIGENT PUMP I/O X This is a general I/O connected to an A/D converter of the microcontroller inside the pump. The default functionality is frequency control: • 0 – 0.05 V DC: Maximum frequency of the pump • 0.06 – 2.75 V DC: Frequency control of the pump • 2.75 – 2.85 V DC: Pump stops • Max input voltage: 3.3 V DC (the pump can be damaged if exceeded) Note that the frequency adjustment can only lower the frequency from the factory default frequency. Normally a pump is calibrated to have its maximum frequency (maximum flow) set as default at factory. The use of I/O X can be...

P/V1500 BLACK INTELLIGENT PUMP CAPACITOR SPECIFICATIONS Xavitech recommends using a capacitor parallel to the power supply (see Figure 2) to reduce the power spikes generated by the electromagnetic motor. For 24-volt pumps, a VCC capacitor is required to not damage the pump. See the recommended capacitors sizes below. Recommended capacitator

P/V1500 BLACK INTELLIGENT PUMP Serial interface COMMUNICATION SETTINGS Asynchronous communication, 9 600 baud, 8 bits, 1 start bit, 1 stop bit, no parity Voltage level: 2.85 V DC (Max 3.3 V DC) SERIAL PROTOCOL Communication package: Pump serial number: Pump serial number, if you wish to address a pump in a system with more than one pump these values can be set from 1-16777215. However, the general call is 0, which will be the default. Pump netId: Can also be used to address single pumps with a value from 1-255. 0 will be used as a general call and that is also the default value. Memory address...

P/V1500 BLACK INTELLIGENT PUMP SERIAL COMMANDS Flow control (pump frequency adjustment) The pump frequency, and thus the flow, can be changed independently of the applied voltage. This is an important feature that enables flow control independently of supply voltage and thus a lower flow can be achieved without reducing maximum vacuum/pressure. This also reduces current consumption and the need for flow restrictors. It is both cost-effective and power-efficient. Command address: 0x017E (hex), 382 (dec) Command package: <0> <0> <0> <0> <1> <126> <129> The frequency is defined as a 16-bit number...
