User’s Responsibility
All Parr 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. Parr engineers will be glad to
discuss available equipment and material
options with prospective users, but the fi nal
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 - not with Parr.
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,
Parr 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 specifi ed 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 Parr Instrument
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 Parr pressure vessels are provided
with either 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 Parr Instrument 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.
Unpack Carefully
Unpack the equipment carefully and check all the
parts against the packing list. If shipping damage is
discovered, report it immediately to the delivering
carriers. Examine the components closely for any
loose parts or shipping damage and be sure to
check all layers of packing materials thoroughly so
as not to overlook any parts which might otherwise
be discarded.

Instructions for the A2110E Motor Controller
Motor Control Module (MCM)
RPM
This optional module can provide a means for
continuously monitoring the stirring speed in a Parr
reactor. It consists of an optical sensor installed in
the overarm drive on the reactor which is then connected to the A2110E Controller.
The connecting cable has a plug which fi ts the
marked socket on the back panel of the controller.
The digital display will show the stirring speed over
a range of 0-2200 rpm with a 1 rpm resolution and
+/- 10 rpm accuracy.
The left display in red shows the stirring speed,
and the right hand display in green shows the rpm
setpoint. The A2110E Controller is designed to run in
either Local or Remote stirring mode. The local/re-
mote switch on the front panel will toggle between
these two modes.
In Local mode, the stirring speed is controlled by
turning the speed control knob on the front panel.
The rpm setpoint has no bearing on the stirring
speed.
In Remote mode, the motor will stir at the rpm setpoint using closed loop PI control. The speed control knob has no bearing on the stirring speed.
The RPM setpoint may be adjusted by following the
steps below.
Note: The MCM leaves the factory in STOP mode.
Before the MCM may be used in remote mode it
must be set to RUN mode. Press the circular arrow
key to display the RUN/STOP screen.
For best results, use the RUN/STOP mode as the
fi nal switch. Return the MCM to STOP mode when
the setpoint motor control is not desired, and return
it to RUN mode as the last step to initiate the setpoint motor control.

Parr Instrument Company
1. Ensure the local/remote switch is in the REMOTE
position and the motor is motor switch is in the
ON (I) position.
2. Ensure the MCM is in STOP mode. This can be
done by momentarily pressing the return key
(circular arrow) once, then using the up or down
arrow to toggle between run and stop and pressing the SET key to solidify the change. Momentarily press the SET key to return to the operating display.
3. Press the UP arrow key until the red display indicates the desired setpoint. The display will blink
indicating that the value has not been set.
4. Press the SET key to solidify the change and the
display will stop blinking.
5. Return the controller to RUN mode by referencing step 1 above.
Motor Speed Control
Parr A2110E Controllers are equipped with a solid
state speed control module for use with the variable
speed, DC motors installed on Parr stirred reactors.
The module itself (approximately 4 inches square) is
mounted inside the chassis on the bottom panel. A
motor switch and a speed adjustment potentiometer
are mounted on the front panel. Each speed control module also requires a resistor matched to the
horsepower of the motor with which it will be used,
as listed in the table below:
Motor
Rating
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
A2110E Controllers furnished as a part of a complete
Parr stirred reactor system will have the proper
resistor installed at the factory. Any controller sold
separately will require a motor specifi cation so that
the proper resistor may be provided.
Always turn the speed control knob fully counterclockwise to the off position before turning on the
motor switch, then advance the knob clockwise
slowly to develop the desired speed. Do not overload the motor. Any high speed or high viscosity
load which trips the circuit breaker is too heavy.
Reduce the speed to avoid overloading and use the
reset button on the rear panel to restart the motor.

Adjustments To Speed Control Board
There are fi ve 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 particular 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 intended 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 re-
ducing 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 fl uctuate, 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 fl uctuate in a cyclical manner.
The MAX, maximum speed adjustment controls the
maximum speed of the motor. To increase the mo-
tor 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. Care should
be taken to ensure the setting will not allow the mo-
tor to turn faster than its maximum rated speed.
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 fi fth 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.
