ULTRA SLIMPAK
AC Voltage/Current Input
Isolating Signal Conditioner
High Accuracy Signal Conditioner with an
Isolated DC Voltage or Current Output
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.
The WV468 has both RMS voltage and RMS current input ranges. Eight AC voltage input ranges (50mV,
150mV, 500mV, 5V, 20V, 50V, 150V & 250V) are DIP switch selectable. Each of these ranges has at least
95% zero and span adjustment. Two AC current input ranges (20mA and 100mA) are also available. Outputs
include 0-10V, 0-20mA and 4-20mA. The WV468 also supports reverse output mode.

Notification of Alarms 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.
Enhanced LED Diagnostics
Other than when executing the pushbutton
calibration routine, the LEDs blink under the
following conditions:
GREEN: Flashes at 2Hz when the input is
under range.
Flashes at 8Hz when the input is
over range.
RED:
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).
Configuring Modules
Unless otherwise specified, the factory pre-
sets the Model WV468 as follows:
Input:
mVAC
Range:
0-500mV
Output:
DC Current
Range:
4-20mA
Reverse Out: Off
Remote Cal: Off
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 S1 to ON if a WVC16 will
be utilized and remote calibration capability
is desired.
3. Set position 2 and 3 of S1 for the desired
output type.
4. Set position 4 of S1 to ON for reverse output
operation.
5. Set positions 5-8 of S1 and positions 1 &
4 of S2 for the desired input range.
It is also possible to remotely select the
setpoints using an Ethernet connection and
the optional WVC16 WebView Communica-
tions Interface module.
Alarms
When used with the optional WVC16 commu-
nications module, the WV468 supports up to
3 alarms, which can be configured as high limit,
low limit and a timer for routine maintenance.
WV16 Communications
Interface (Optional)
The 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 program-
ming 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 diag-
nostic 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 e-
mail message for up to 10 recipients. The
module also contains a countdown timer that
can be used to notify when routine mainte-
nance is required, such as re-calibration. The
internal temperature of the module can also be
monitored. All memory to support the signal
conditioners historical data, storage of the
web pages and all e-mail messages is con-
tained in the WVC16.
The WVC16 downloads a JAVA applet to
the clients computer. The applet provides
access to the signal conditioners 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
See the WVC16 Data Bulletin for more
detailed information.
Calibration
The calibration procedure is contained in the
Installation & Calibration Instructions docu-
ment, 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:
a) Input Type, Range and Units.
b) Output Type, Range and Units.
