RTD Input Isolating Signal Conditioner - WV418

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).

Configuring Modules

Unless otherwise specified, the factory presets the Model WV418 as follows:

1. For other ranges, refer to the SWITCH SETTINGS table. Reconfigure switches S1 and S2 for the desired input type and range.
2. Set position 1 of S2 to ON if a WVC16 will be utilized and remote calibration capability is desired.
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.

Alarms

When used with the optional WVC16 communications module, the WV418 supports up to 3 alarms, which can be configured as high limit, low limit and a timer for routine maintenance.

WV16 Communications Interface (Optional)

TThe WVC16 Communications Interface adds functionality never before found in a signal conditioning system. The WVC16 interfaces with Ultra SlimPak II devices via an internal infrared communications link (no programming required) and provides the ability to connect as many as 32 modules to the intranet, allowing the user to view process data on a near real time basis, perform data logging functions on specified modules, calibrate the signal conditioners remotely, and view diagnostic information.

The WVC16 contains a web page server and an e-mail server. Browsers supported include Internet Explorer 5 or later and Netscape Navigator 4.7 or later. The user has the ability to have setpoint trip conditions generate an email message for up to 10 recipients. The module also contains a countdown timer that can be used to notify when routine maintenance is required, such as re-calibration. The internal temperature of the module can also be monitored. All memory to support the signal conditioner’s historical data, storage of the web pages and all e-mail messages is contained in the WVC16.

The WVC16 downloads a JAVA applet to the client’s computer. The applet provides access to the signal conditioner’s data, which includes the following:

• Module configuration summary
• Module configuration editing
• Diagnostic/warning status
• Alarm setup & status
• E-mail setup, editing & address book
• Process variable viewing

Calibration

The 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).

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. a) Input Type, Range & Units (mA, mV, V).
2. b) Output Type, Range & Units (ma, mV, V).
3. c) Reverse Output (ON/OFF)
