ULTRA SLIMPAK(R) II WV418 DC Powered RTD Input Isolating Signal Conditioner High Accuracy Signal Conditioner with an Isolated DC Voltage or Current Output WV418-2000 Lower Power Requirements with SmartPower Improved Accuracy Bussed Power with Plug-in Power Clips Removable Terminals for Easy Service RoHS Compliant Touch Cal for Best Stability and Accuracy DIP Switch Configuration Supports 2, 3 or 4 Wire RTD's Description The Ultra SlimPak II is an exciting new line of isolating signal conditioners from Action Instruments with greater accuracy and better stability than virtually any other signal conditioners on the market today. The Ultra SlimPak II features Smart Power, which eliminates wasted power for low loop resistance loads in the current output mode. Enhanced LED Diagnostics Other than when executing the pushbutton calibration routine, the LEDs blink under the following conditions: The WV418 supports 2-wire, 3-wire or 4-wire Pt100 RTDs with alphas of either 0.00385 or 0.00392, as well as Cu10. Ranges are DIP switch selectable or (optionally) PC programmable. Outputs include 0-10V, 0-20mA and 4-20mA. RED: Smart Power The Ultra SlimPak II uses Smart Power to control its output supply. Smart Power automatically adjusts the the voltage to drive the output loop to the required current. A low impedance current loop will subsequently require less voltage than a loop with higher impedance. Previous designs provided only a single supply at the highest voltage required to drive the highest impedance load. Using Smart Power results in power savings and reduces the operating temperature of the signal conditioner. GREEN: Flashes at 2Hz when the input is under range. Flashes at 8Hz when the input is over range. Flashes at 2Hz when the output is under range. Flashes at8Hz when the output is over range. An Under Range condition exists when the signal is lower than the operational low value minus 6.25% of the operational span. An Over Range condition exists when the signal is higher than the operational high value plus 6.25% of the operational span. A voltage output short circuit may cause an under range condition (RED blinking at 2Hz rate). A current output open circuit may cause an over range condition (RED blinking at an 8Hz rate). There could be two or more LEDs blinking at the same time, which means the module has more than one error condition. Only when all error conditions have been removed will the LEDs be back to normal (Green ON, Red and Yellow Off). Calibration See the calibration flowchart in Figure 3. The complete calibration procedure is contained in the Installation & Calibration Instructions document, which is available on our website (www.actionio.com). You can also obtain it by telephoning Action technical support (703-669-1318). Configuring Modules Unless otherwise specified, the factory presets the Model WV418 as follows: Input: Range: Output: Reverse Out: Remote Cal: Pt100, 3-wire, alpha = 0.00385 -200 to 600C 4-20mA Off Off Note that Custom Calibration (option C620) is available from the factory (settings MUST be within the units specifications). For a C620, specify the following: 1. For other ranges, refer to the SWITCH SETTINGS table. Reconfigure switches S1 and S2 for the desired input type and range. a) Input Type, Range and Units. 2. Set position 1 of S2 to ON if a WVC16 will be utilized and remote calibration capability is desired. b) Output Type, Range and Units. c) Reverse Output (ON/OFF) 3. Set position 2 and 3 of S2 for the desired output type and range. 4. Set position 4 of S2 to ON for reverse output operation. 5. Set positions 1-7 of S1 and positions 5 & 6 of S2 for the desirred input range. It is also possible to remotely select the setpoints using an Ethernet connection and the optional WVC16 WebView Communications Interface module.
