2.2.2 Electrical Power Connections
Unless specifically ordered, the standard system requires a supply of 115 VAC,
2.2.3 Compressed Air Supply
The system may require a supply of clean, oil and particulate free air to drive pneumatically activated valves, create suction (pumping) eductor action (demand more flow), or for use as zero fluids. In general, a 2 liter/minute supply of compressed air between 80 to 120 psig is usually sufficient. The air supply must have far greater capacity when purging of the system or when eductors ejectors are used (special systems).
2.2.4 Pipe Connections
Refer to Appendix Piping Drawings for information about pipe connec- tions. On special systems, consult the text in the manual that describes your particular sample system in detail.
2.2.5 Signal and Alarm Output Connections
Signal and alarm output connections are made inside the control unit to terminal blocks mounted on the interface PC board.
Note: For current outputs, the signal circuit resistance, including accessory devices, must not exceed 1000 ohms. The alarm contact circuit must not draw more than 3 amperes at 250 VAC
2.2.6 Sample Delivery System
The sample delivery system should be designed to operate reliably and must be of large enough capacity to avoid flow stops or bubbles in liquid samples. A pump is required only if there is insufficient pressure to reliably supply the sample to the system equipment panel. Do not complicate the delivery system by adding a pump unless it is absolutely necessary. If a pump is required, select a type that can handle the sample (corrosion), as well as meet the area classification and Environmental conditions. Choose a pump that can also supply sufficient flowrates to meet anticipate flow response times based upon sample delivery
