Introduction
VCT & VC Multichannel Transmitter
The VCT family of transmitters utilize the latest LED based strobe techniques
using multi-frequency light measurement. The VCT measures Consistency in the
0 to 12%CS range. The VC multichannel measures Consistency on channel one
and one of the following measurements on channel two: Ash, Brightness,
Freeness, Kappa, Fiber Length or Shives Content.
The Remote Display Unit (RDU) provides a local display of the measured values
and serves also as a simple menu-driven calibration and troubleshooting
interface.
The RDU includes two analog 4-20 mA outputs, 3 dry contact binary inputs and
3 contact outputs.
Process Measurement Techniques
The VC family of transmitters measures process parameters by transmitting
multichannel strobes of light into the pulp and measuring the back-scatter characteristics. These
measurement values are calibrated by sampling and laboratory analysis of process and the measurement
accuracy is determined by the accuracy of the laboratory analysis results.
Since the calibration is dependent on sampling and analysis, it is imperative that the sampling techniques
described in the Calibration section are carefully followed.
Installation
Transmitter Installation
The location of the transmitter should be on the high-pressure
discharge of the pump in the turbulent flow. The optimal
location is on a 45-degree angle off the centerline of the
discharge.
Drill a 34 mm diameter hole at 15°angle into the pipe so that
the nipple inserts through the pipe wall. After welding, ensure
that nothing (welding slag) obstructs the insertion path
through the pipe.
Attach the isolation ball valve to the coupling. Once this is
complete and the valve closed, the process can be restarted.
Important: while the process is down, attach the ball valve and
check that the transmitter will insert fully into the pipe and
can be locked in the place with the locking nut.

Mounting the Transmitter
To mount the transmitter, insert the screw fitting
on the end of the transmitter into the ball valve
and tighten the screw fitting (a).
Open the ball valve and push the transmitter
through the valve and lock in place with the locking
nut (b). In some cases, under higher pressure
applications, the insertion tool may be required.
(Insertion tool is optional and is not included with the
purchase of the transmitter).
To remove the transmitter, reverse the above steps.
Warning: When removing the transmitter, do not
loosen screw fitting (a) unless the ball valve is closed!
Electrical Connections
This figure shows a combination of many of the components of
the VC family. An order will contain a combination of these
components along with any additional components associated
with special orders.

Supply voltage to the transmitter is 24 Vdc and requires up to 200 mA
current. It is recommended that a shielded twisted-pair cable is used as a
signal cable.
The signal cable should not be installed near high- voltage cables, large
motors or frequency converters.
The shield of the cable should be grounded at the end of the power
supply or in accordance with the recommendations of the manufacturer
of the control system used and the regional electrical code. At the RDU

The Satron VCT transmitter remote display unit (RDU) can be provided
with a wall box which can have a 20 m cable between the transmitter and
the sensor unit. Inside the RDU, there is a terminal for up to 3 binary
Inputs (DI1, DI2, DI3). 3 relay outputs (DO1, DO2, DO3) and 2 analog 4-
20 mA output signals (IO1, IO2).
The signal cable between the RDU and transmitter should not be
installed near high-voltage cables, large motors or frequency converters.
The wiring connections to the RDU are shown below.
Hint: Under the cover of the RDU there’s a small hole in the upper left
corner (2), where you can insert a screwdriver to support the cover while
making the wiring connections.

Initial Set-up
The initial set-up consists of three steps.
1. Set the Date and Time
2. Set the operating range for Consistency (IO1).
3. If a Sampling Switch was not purchased and a user supplied
Switch is not being added, skip this step. If a user supplied
Sampling Switch is added, you must configure the Sample Digital
Input (DI1).
The Satron RDU is the local interface and consists of a liquid crystal
display (LCD) and operating keys.
The RDU is able of displaying live operating conditions, perform diagnostic tests, view device information
and set configuration parameters for proper operation.
The 8-character LCD with backlight displays information with letters and numbers.
The operating keys (Esc, Up, Down and Enter) allow the navigation through the menus and allow the
modification of the display parameters:
•Press ENTER to accept a configuration, move to a lower menu level, accept a command or enter a
setting or parameter value into the transmitter memory.
•Use the UP arrow to move to a higher menu level or to increase a parameter value.
•Use the DOWN arrow to move lower in a menu level or to decrease a parameter value.
•Press ESC to move back towards the top of the main menu or to cancel the current action.
Setting the Date and Time
It is very important to set the correct date and time in the transmitter. The date and time are used to time
stamp the samples extracted from the process and to mark the diagnostic events that may occur during
transmitter operation.
