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 WV448 is a bridge input signal conditioner supporting bridge
input full scale ranges of ±5mV to ±200mV, (default is ±50mV). The
switch selectable output ranges are 0-10VDC, 0-20mA and 4-20mA.
All the input and output ranges are fully adjustable via pushbutton
calibration. The default output range is 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 at 8Hz 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).
Configuring Modules
Unless otherwise specified, the factory presets the Model WV448
as follows:
Input: 0-30mV
(using ±50mV range)
Excitation: 10V
Output: Current
Range: 4-20mA
Remote Cal: 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).
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 switch S1 for the desired input type and range.
2. Set position 1 of S1 to ON if a WVC16 will be utilized and remote
calibration capability is desired.
a)
Input Range.
b)
Output Type, Range & Units (mA, V).
c)
Excitation Voltage.
3. Set position 2 and 3 of S1 for the desired output type.
5. Set positions 4-6 of S1 for the desired input range.
It is also possible to remotely select the setpoints using an Ethernet
connection and the optional WVC16 WebView Communications
Interface module.
