URGE UPPLY The P-840LT Pour Point Analyzer’s provides for an optional inert gas purge to prevent condensation from forming on the cryocooler. This optional purge, if supplied, requires clean, dry nitrogen (98% pure) or other inert gas at a pressure of 0.7 bar (1.0 psi); This insert gas connection is made on the left side of Measurement Enclosure (Figures 3-2a and 3-2b).
Page 27: Wiring
Proper building codes and safety regulations should be followed. The P-840LT Pour Point Analyzer requires an independent 100 to 240 VAC (±10%), 50/60 Hz. power supply. AC power connections are made through the Customer Connections box attached to the upper left of the top enclosure (Figures 3-2a and 3-2b).
Page 28: Control Room Signals
(Figure 3-4) or the Control Enclosure (Figure 3-6). Analog Output One isolated 4-20 mA output is standard on the P-840LT Pour Point Analyzer. An optional two additional 4-20 mA outputs may be provided. These connections are made in the Customer Connections Enclosure (Figure 3-4).
Page 29: Modbus
ModBus is available as a factory-installed option which utilizes either the Analyzer’s TCP/IP connection for ModBus or its serial ModBus connection. This connection is made in the Control Enclosure (Figure 3- 6). Consult ORB Instruments for more information. Digital Inputs The Analyzer incorporates four sets of voltage dry contacts that allow the control room to remotely activate selected functions.
