User’s Responsibility
All Reactors and Pressure Vessels are designed and manufactured with great care to assure
safe operation when used within their prescribed temperature and pressure limits.
But…the basic responsibility for safety when using this equipment rests entirely with the user;
who must:
1. Select a reactor or pressure vessel that has the capability, pressure rating, corrosion
resistance, and design features that are suitable for its intended use. Our engineers will
be glad to discuss available equipment and material options with prospective users, but
the final responsibility for selecting a reactor or pressure vessel that will perform to the
user’s satisfaction in any particular reaction or test must rest with the user
.
In exercising the responsibility for the selection of pressure equipment, the prospective
user is often faced with the choice between over or under-designed equipment. The
hazards introduced by under-designed pressure vessels are readily apparent, but
the penalties that must be paid for over-designed apparatus are often overlooked.
Recognizing these criteria, our reactors and pressure vessels are offered in several
different styles, each designed for convenient use in daily operation within certain
temperature and pressure limits, using gaskets, closures, and other elements carefully
selected for safe operation within the limits specified for that design. But in order to
preserve the validity of these designs, all temperature and pressure limits must be
observed, and no attempt should be made to increase these limits by making alterations
or by substituting components which are not recommended by Company.
2. Install and operate the equipment within a suitable barricade, if required, with appropriate
safety accessories and in full compliance with local safety codes and rules.
All standard pressure vessels are provided with either a suitable relief device or
a means to attach one (typically in the form of a plugged opening). When a pressure
vessel is delivered without a pressure venting device, it is the customer’s responsibility
to provide pressure relief in order to protect the operator and the equipment from
destructive high pressures. If you need more information or need help in selecting a
proper relief device, please contact Company.
3. Establish training procedures to ensure that any person handling the equipment knows
how to use it properly.
4. Maintain the equipment in good condition and establish procedures for periodic testing to
be sure the vessel remains structurally sound.

COMPONENT SUMMARY
4848T Reactor Controller, Front Side
Switches and Indicators
The MAIN POWER switch on the back of the con-
troller will cut off power to the controller. Take care
to position the controller such that the main power
switch may be accessed easily when the controller
needs to be disconnected.
The HEATER Switch is a manual, three-position,
illuminated switch which controls the amount of
power sent to the heater. In the HIGH (II) position,
full power is developed by the heater. In the middle
(O) position the heater is off. In the LOW (I) position,
a diode is switched into the system to allow only one-
half of the rated voltage to be supplied to the heater.
This low setting will be most useful when operating
the reactor at temperatures below 175 °C. Power
for the heater is supplied through a solid state relay
controlled by the temperature control module. The
light in the heater switch will glow only when current
is flowing to the heater.
The HIGH LIMIT indicator light will glow if the
controller receives an indication from any of its
sensors that a high temperature or high pressure
limit has been reached and the HIGH LIMIT RESET
has opened. When the light comes on, the user
must find the source of the problem, correct it, and
then manually reset the system using the HIGH
LIMIT RESET button on the front of the controller.
The MOTOR CONTROLS consist of:
1. AUTO/MANUAL switch
2. ON/OFF(I/O) switch
3. SPEED control knob
The SPEED control knob should be turned down
to a minimum setting before turning on the motor
switch to minimize electrical surges within the
speed control unit.
When the auto/manual switch is in manual mode,
the speed control knob will adjust the motor stir-
ring speed. When the auto/manual switch is in
auto mode, the RPM module will adjust the motor
stirring speed.

Protective Fuses and Relays
4848T Reactor Controller (230V), Back Side
An instrument fuse is mounted on the back panel.
This is a Fast-acting, 250VAC, 2.0 amp fuse, intend-
ed to protect the temperature control module and
any installed display modules.
The motor reset/motor fuse provides overload
protection for 0-90VDC motors. This is a re-settable
breaker designed to protect the motor if it becomes
overloaded. The breaker will have a rating selected
to match the motor on the apparatus.
A lighted fuse holder provides protection for 0-180
VDC motors. A light will come on if the motor
becomes overloaded and the fuse burns out. The
fuse rating will be selected to match the motor on
the apparatus.
A load fuse is mounted on the back panel on 115V
systems. This fast-acting, 250VAC, 20 amp fuse
is intended to protect the controller and prevent
electric shock hazard from fault from occurring.
Two load fuses are mounted on the back panel on
230V systems. These are fast-acting, 20 Amps, 250VAC
and are intended to protect the controller and to pre-
vent electric shock hazard from fault from occurring.
The 4848T Controller has a number of fuses which
are intended to be field serviceable. See the Parts
List Section on page 23 for more information.
CAUTION! Unplug unit before servicing.
For continued protection against
possible hazard, replace fuses with same
type and rating of fuse.
Thermocouple burnout protection is included in
each of these controllers. If the thermocouple
should burn out, or if there is a break in the ther-
mocouple circuit, the apparent temperature will
rise to the top of the sensor limit, triggering a
sensor break alarm.
High Limit Reset
Each Series 4848T Controller has a high tempera-
ture limit control which will trip the High Limit
Relay and shut off the heater if the temperature
reaches a preset level. If tripped, the lockout relay
will pop out, thereby preventing the system from
heating the reaction when the temperature falls
back below the limit setting. This must be manually
reset before heating can occur again.
On Model 4848T Controllers the high temperature
limit is preset at the factory to 375 °C for most
systems. If the temperature exceeds the limit, the
controller alarm condition will appear.
Motor Speed Control
4848T Controllers are equipped with a solid
state speed control module for use with the variable
speed, DC motors installed on stirred reactors.
The module itself (approximately 4 inches square) is
mounted inside the chassis on the bottom plate. A
motor switch and a speed adjustment potentiometer
are mounted on the front panel. Each module also
requires a resistor matched to the horsepower of
the motor with which it will be used, as listed in the
following table:
Motor
Rating
Motor
Voltage
Resistor
Required
Part
Number
1/17 HP 90 VDC 0.25 ohm 876E6
1/8 HP 90 VDC 0.10 ohm 876E3
1/4 HP 90 VDC 0.05 ohm 876E
1/4 HP 180 VDC 0.10 ohm 876E3
1/2 HP 90 VDC 0.025 ohm 876E2
1/2 HP 180 VDC 0.05 ohm 876E
3/4 HP 180 VDC 0.035 ohm 876E5
4848T Controllers furnished as a part of a complete
stirred reactor system will have the proper
resistor installed at the factory. Any controller sold
separately will require a motor specification so that
the proper resistor may be provided.

Always turn the speed control knob fully counter-
clockwise to the off position before turning on the
motor switch, then advance the knob clockwise
slowly to develop the desired speed. Do not over-
load the motor. Any high speed or high viscosity
load which trips the circuit breaker (90 VDC motors)
is too heavy. Reduce the speed to avoid overload-
ing and use the reset button on the rear panel to
restart the motor.
Adjustments To Speed Control Board
There are five trimpots in the speed control module
that can be used to adjust the performance of the
motor. These are set at the factory for optimum
performance and should not be disturbed unless
customized settings are required to match a par-
ticular set of operating conditions. The instructions
below should be followed carefully if these controls
are to be readjusted.
The CL, current limiting/torque adjustment is set at
the factory to 1.5 times the motor rating. It is intend-
ed to protect both the module and the motor against
overloads and heavy surge currents during startup.
It can also serve as a torque limiting device by reduc-
ing the maximum power output of the system.
The IR, compensation adjustment is used to improve
motor control under varying load conditions. If the
loads do not fluctuate, this control can remain at
approximately one-fourth of full setting. But if the
motor speed drops more than 2% under load, this
adjustment should be increased. If it is set too high,
the motor speed will fluctuate in a cyclical manner.
The MAX, maximum speed adjustment controls
the maximum speed of the motor. To increase
the motor speed, turn the control knob on the
front panel to its maximum setting, then use the
MAX trimpot to raise the speed to the desired
level. Note, however, that the motor may become
dangerous if the speed is raised above the motor’s
rated rpm.
The MIN, minimum speed adjustment can be used
to raise the minimum motor speed. To change this
setting, turn the control knob on the front panel to
its minimum setting, then adjust the MIN trimpot
to obtain the desired minimum speed, this adjust-
ment will also affect the maximum setting, making
it necessary to adjust both MAX and MIN trimpots
to obtain the desired spread.
The ACCEL, acceleration adjustment is normally set
to provide controlled acceleration from zero to full
speed in 2 seconds. It can be adjusted to higher or
lower acceleration times anywhere between 0.5 and
4 seconds, but changing this setting will affect the
MAX speed and IR compensation which will have to
be readjusted. If the acceleration time is reduced to
0.5 seconds (6 o’clock trimpot position), increase the
IR trimpot one quarter turn clockwise and decrease
the MAX trimpot one fifth turn counterclockwise. If
the acceleration time is increased to the maximum
time of 4 seconds (full rotation), the IR trimpot must
be decreased and the MAX increased in the same
rotation amounts mentioned above.
Solenoid Valve Module
This module provides a solenoid valve, a metering
valve and all parts needed to assemble an automatic
cooling system for any reactor. It usually is installed
in a cold water line with a flow connection to the
cooling coil and an electrical connection to the
cooling socket on the back of the 4848T Controller.
Coolant will then be admitted to the coil whenever
cooling is called for by the controller, thereby mini-
mizing any temperature overshoot. This system is
particularly advantageous when holding fixed tem-
peratures below 150 °C or for controlling exothermic
reactions. Compressed air can be used as a coolant
if the amount of heat to be removed is not large.
Access to the Controller Cabinet
To open the controller cabinet, unplug the power
cord and remove the five screws on each side of
the enclosure. Then lift the top cover upwards,
providing full access to all internal components.
CAUTION! Inside of controller cabinet
should be accessed by qualified
personnel only.

Tuning
The 4848T has a set of default PID values intended
to give reasonable control across a wide range of
conditions, but tighter control can be had by auto-
tuning the system.
To autotune the temperature meter from the main
screen, select the following:
1. Select the Display Icon in the icon
bar at the top of the screen
2. Select the Settings Option from
the main display
3. Select the Display Icon in the icon
bar at the top of the screen
4. Select the Tuning Option from
the main display to enter the
TemperatureTuning screen
The PID settings can be adjusted here manually.
Unless the operator has a background in PID
control, however, autotuning is recommended.
Autotuning is a method to help the controller deter-
mine the best PID settings to control tightly around
the intended setpoint. To do an autotune, fill the
pressure vessel with conditions as equivalent to
the intended process as possible (do a blank run),
and heat it up to the intended setpoint. Once the
temperature has reached setpoint, click on AT to
engage the autotune. During the autotune process,
the temperature will rise by a few degrees, drop
back down to setpoint, and repeat this process
perhaps three times. This can take a good deal of
time, especially in large vessels or in cases at low
temperatures. When the autotune is complete,
the controller will return to regular setpoint mode,
maintain the intended setpoint, and it will have
rewritten the PID values here to better values.
If you need to halt the autotune before completion,
click on the AT button again.

COMMUNICATIONS
This section provides instructions on how to
use the 4848T communication interfaces. As a
standard, the 4848T is equipped with an Ethernet
interface for user communications.
Ethernet Communications
The 4848T provides two forms of Ethernet com-
munication interfaces for monitoring and control-
ling the system across a network.The web server
interface provides a monitor only connection, while
the VNC server interface allows a user to manipu-
late and control the 4848T remotely by viewing the
4848T display directly on their PC screen.
NOTE: In order to use Ethernet communications, the
4848T must be properly connected to a network. To
connect the 4848T to a network, connect the touch-
screen’s Ethernet port to your network using a standard
CAT5 cable connection. Note that after connecting the
network cable, it may be necessary to cycle power to
the 4848T in order for it to obtain a valid IP address.
Guide to Smart Networking Practices
The expansion of Ethernet onto the industrial floor
has brought forth a new realm of possibilities from
the gathering of information to the inherent control
of equipment from anywhere around the world.The
flexibility and convenience that this provides makes
it a very desirable feature for new equipment.The
4848T provides this ability, but there are consider-
ations that must be taken by the end user to protect
their equipment and investment.
Just like placing a personal computer on the internet
opens it up to outside attack, placing your 4848T on a
network poses the same risk.The first thing to re-
member is this:The most likely cause of problems is
not a hacker trying to sabotage your equipment, but
more often to be related to the ubiquity of PCs with
Ethernet cards, the ease with which your own co-
workers can “hang stuff on the network”, and careless
or nonexistent internal security measures. Accidental
problems are more common than deliberate ones.
Allowing anyone access to the 4848T by placing it
on the office LAN, also opens the door for accidental
shutdown, damage to equipment, loss of data, lost
time, etc. This is possible even by the most well-
intentioned co-workers. Thus, there are several steps
that should be taken to minimize this risk.
The first is to never mix your office LAN with your
control LAN.The control LAN should be a separate
network that consists of your 4848T controller(s) and
possibly any other equipment that you may have that
is related to the operation of the system. It should be
separated from your office LAN by a firewall, or at
minimum, a bridge or router. A control network and a
business network have two entirely different purpos-
es and their interaction should be closely controlled.
It is also unwise to assume that any Ethernet capable
devices themselves have any security features at all.
The 4848T VNC server only provides minimal single-
password based security access. Separating the con-
trol LAN from the office LAN using a firewall would
increase security and only allow control access that
is based on a combination of IP source address,
destination address, and port number.This is by no
means completely “hacker-proof”, but it should keep
the well-meaning co-workers out.
Another hazard is connecting consumer “plug and
play” devices to your control LAN. A printer for
example, might flood the network with traffic in a
“broadcast storm” as it tries to self-configure or
advertise its presence to all nodes on the network.
Faulty devices, for example defective NIC cards,
can transmit large amounts of bad packets (i.e.,
runts, which are abnormally short Ethernet frames)
into your network. Using switches instead of hubs
will limit the effect of such problems.
The most commonly overlooked source of prob-
lems is cabling. Not all cables are created equal.
Electrical noise generated by factory equipment or
other electrical equipment in the area, could easily
corrupt transmitted data over the network and
cause devices to “lock up” or shut down the VNC
server, both of which then require the 4848T to be
shut down and restarted to clear the problem.
Select the right cable for the environment. Shielded
twisted pair (STP) cable is naturally more noise
immune and is preferable to unshielded twisted pair or
UTP in noisy situations. STP should have at least 40dB
CMRR and less than 0.1pF capacitance unbalance per
foot. Ground STP cable, making sure the ground is
connected only at one end. CAT5 STP patch panels
normally provide a grounding strip or bar. Hubs and
switches don’t provide grounding, use cables.

18
It’s wise to be pessimistic about a cable’s ability to
reject noise from 230 VAC and 460 VAC power lines
and electrically “noisy” equipment in the area.
Capacitance imbalance in cables greater than 70pF
per 100m can introduce harmonic distortion result-
ing in bit errors.The cost of cable is quite small
compared to total equipment cost, so if you’re
looking to save money, this is not a place to do
it. Choose a well designed cable to minimize bit-
error rate after installation, and that will give faster
throughput with fewer glitches.
Using the Web Server
The 4848T web server allows a user to remotely
monitor operations anywhere via a PC’s standard
web browser. When enabled, the web server pro-
vides a detailed status page of the current operat-
ing conditions.The web server can be enabled and
disabled by pressing the web server (Www.) button
on the communications screen (select “Comms”
from the Device\Settings\Set menu).
You must use the assigned IP address to access the
4848T.The IP address is shown on the communica-
tions screen and is also included in the notifications
list. Write down the IP address so you will have it
later to enter into your web browser.
NOTE: Contact your network administrator prior to
enabling the web server of the 4848T. Company policy
may prohibit the use of web servers for security rea-
sons. Future Design Controls is not responsible for the
use of, nor makes any claims as to the security of the
web server interface over your network. The use of
the web server is the responsibility of the end user.
To access and view the 4848T web page, enter
the following link in your PC’s browser address
window: http://”IPaddress”/orion.html. Using the IP
address from the sample screen, the entry would
be: http://192.168.1.2/orion.html.The following
example is typical of the 4848T web page appear-
ance.The web page updates automatically every
30 seconds and provides information on each
individual control loop, ramp/soak program status,
alarm status and system event status.
Using the VNC Server
The 4848T VNC server allows a user to remotely moni-
tor and control 4848T by directly viewing and
manipulating the touchscreen over the network.You
must use the assigned IP address and VNC port number
to access 4848T.The IP address is shown on the commu-
nications screen and is also included in the notifications
list. Write down the IP address and port number so you
will have it to enter into your VNC viewer.

There are many VNC viewers available for both PC
and tablet use. Due to the ever changing market and
availability of such applications, it is not possible to
test them all for compatibility or provide assistance
for their use with the 4848T. It is the responsibil-
ity of the end user to test the chosen VNC client
for compatibility with the 4848T prior to putting
the unit into service. If the VNC client viewer has
compatibility issues with the 4848T, it can cause the
VNC server to stop responding and/or shut down
requiring power to be cycled to the 4848T in order
to reboot the system and restart the server.
Company has tested and recom-
mends the use of RealVNC’s viewer. It has been
tested for compatibility with the 4848T and a free
version can be obtained from RealVNC for PC/MAC
use. RealVNC does offer a version for the iPad that
can be obtained through the App Store for a small
fee.
NOTE: Contact your network administrator prior
to enabling the VNC server of the 4848T. Company
policy may prohibit the use of VNC servers and/
or viewers for security reasons.
Company is not responsible for the use of, nor
makes any claims as to the security of the VNC
server interface over your network. The use of the
VNC server is the responsibility of the end user.
Once the connection is established, the current
4848T display will be shown on your desktop.The
image will be a duplicate of what is on the 4848T.
As you manipulate the screen, the display of the
4848T will also be manipulated so that any local
operator will be able to see what is happening and
vice versa.
Multiple instances of the VNC viewer can be started
on your PC. By running multiple viewers, you can
have access to multiple 4848T controllers right
from your desktop.The heading of each VNC viewer
window will use the “VNC Device Name” entry for
the header. By entering a unique name for each
4848T, you can identify each VNC connection and
know which system you are accessing.
The VNC viewer is meant to be used for short term
control access to the 4848T. It is not meant for long
term monitoring of system operation. If long term
monitoring access is desired, use the built-in web
server of the 4848T or a PC with FDC software to
monitor and control the 4848T over its serial com-
munications port. The web server interface and PC
software is designed for long term monitoring and
status updates.
Due to the nature of VNC operation, and for secu-
rity reasons, the VNC viewer connection should
not be left open on your desktop.The viewer con-
nection should be opened in order to perform the
necessary control and/or status check of system
operation, and then closed once the task is com-
plete. Accidental manipulation of the control or
erroneous network activity could cause connection
problems over the VNC interface and result
in the VNC server shutting down and requiring the
4848T to be restarted in order to regain access.
NOTE: Some viewers may also contain additional
features for file transfer and other high level func-
tions. These functions are NOT compatible with
the 4848T. Any attempt to use them may cause
the 4848T VNC server to malfunction and require
power to be cycled in order to reboot the system.
