OBJECTIVES • Familiarize the user with certain issues relevant to the MonoScan operation with a power supply. • Familiarize the user with certain issues relevant to the SmartScan operation with a power supply 3. INTRODUCTION Connecting MonoScan or SmartScan units to an appropriate power supply is imperative to maintain the units' orderly operation and to ensure that measurement results won't be influenced by noisy area that might cause inaccurate readings. This document describes the electrical requirements needed in both MonoScan and SmartScan units as well as the other related technical necessities. __________________________________________________________________ AN0016GE Rev: - 1.00 Page 4 of 8 ? Copyright Solid Applied Technologies Ltd. 4. POWER SUPPLY REQUIREMENTS FOR SMARTSCAN UNITS (CE AND EX MODELS) SmartScan units can be supplied in either DC or AC configuration. When using a DC configured unit the operating voltage range is as follows: 18 to 30 VDC. External fuse: Slow Blow* 1.25 A, T type. The external fuse should be applied on the DC power line as a protection on the unit against current bursts. Protection on the SmartScan unit can be maintained either by using a serial fuse on the power line or a power supply with built-in current limit. When using an AC configured unit the electrical voltage range is as follows: 100 – 230 VAC, 50/60Hz, 70mA max. The AC model has an internal 1.25A fuse, which protects the unit and ensures its safe operation. SmartScan AC/DC converter and power inputs L Notes: Recommended Slow Blow fuse type to be used for SmartScan DC configured unit is: 0034.3117 Schurter. __________________________________________________________________ AN0016GE Rev: - 1.00 Page 5 of 8 ?

For CE model the operating voltage range is as followes: 12 to 28 VDC, external fuse: 400mA. The external fuse should be applied on the DC power line as a protection on the unit against current bursts. Protection on the MonoScan unit can be maintained either by using a serial fuse on the power line or a power supply with built-in current limit. The drawing below depicts the Non-Intrinsically Safe Connections of the MonoScan unit: __________________________________________________________________ AN0016GE Rev: - 1.00 Page 6 of 8 ? Copyright Solid Applied Technologies Ltd. 5.1 Power Supply and Load Resistance Recommendations The following table specifies the recommended resistance range for each power supply voltage for non Intrinsically safe and CE Model. Power Supply Voltage Minimum Current on Resistor Maximum Current on Resistor 12 V 0 ? 50 ? 15 V 0 ? 220 ? 24 V 41 ? 610 ? 28 V 68 ? 820 ? 5.2 Ripple/Noise Parameters Recommended for the Power Supply The following ripple/noise parameters are recommended for the power supply: For less than 15 V: 75 mV p-p max For more than 15 V: 100 mV p-p max L Note: An is displayed if there is a noise in the MonoScan's area that might be caused by other equipment connected to the power supply. To overcome such an alert please check that the power supply is appropriate. __________________________________________________________________ AN0016GE Rev: - 1.00 Page 7 of 8 ?

For Intrinsically Safe model the operating voltage range is: 18 to 28 VDC, external fuse is not required. The drawing below depicts the Intrinsically Safe Connections of the MonoScan unit: L Note: For more details on approved barriers specifications for IS installations, refer to the MonoScan UM Chapter 2, Installing MonoScan. __________________________________________________________________ AN0016GE Rev: - 1.00 Page 8 of 8 ?
