(
Continued)
The pneumatic package includes a
pressure regulator with gage located
inside of the support stand housing. It
can be accessed by removing the back
panel of the support stand. The
regulator has been preset to 50 psi.
The regulator can be adjusted by lifting
up on the cap. Rotate clockwise to
increase pressure, counter-clockwise to
decrease the amount of pressure sent
to the pneumatic lift cylinder. Press the
cap back down after setting the
pressure.
The flow control valves have been
preset for optimum performance. Both
the speed and lifting capacity of the
pneumatic lift package can be adjusted
with the flow control valves located on
the input and output ports of the
pneumatic cylinder.
3. The Series 4848 Reactor Controller is
attached either to the work surface of the
moveable floor stand or to the shelf of
the fixed head support stand. The
controller/shelf attaches to the side panel
of the fixed head stand.
Set the Temperature Controller near the
reactor, leaving a space of at least six
inches between the controller and the base
of the reactor so that the controller will not
be unduly affected by radiant heat. Connect
the reactor to the controller using
information contained in its Instruction
Manual 548M or follow the steps below.
Labeled connections are provided on the
rear panel of the controller.
Parr Cooling Only:
The Parr Cooling output connector is to be
used only with Parr Instrument Company
cooling solenoid valve assemblies supplied
with the appropriate cooling power cord.
Parr Heating Only:
The Parr Heating output connector is to be
used only with Parr Instrument Company
heater assemblies supplied with the
appropriate heater power cord. Note: Do not
make connections to a Variac, Powerstat or
the like to attempt to control the heating
output. The heavy inductive load on the
primary side of such devices can destroy the
internal sold state relay located in the 4848
controller.
Motor:
Secure the clamp on motor cord
to the controller with the
provided screw next to the motor
socket for safety purposes.
The Motor output connector is to be used
only with Parr Instrument Company motor
assemblies supplied with the appropriate
motor power cord.
