ASSEMBLE THE REACTOR
( Continued )
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. 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 solid 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.
4.
Connect the heater cord from the
heater into the heater socket on the
rear panel of the Series 4848 Reactor
Controller.
5.
Plug the motor cord into the motor
socket on the rear of the controller.
Secure the clamp on the
motor cord with the
provided screw next to the
motor socket for safety
purposes.
6. Connect the thermocouple and
extension wire to both the
thermocouple and to the controller in
the “Primary Temp Input” position on
the rear panel. Insert the thermocouple
in the thermowell.
7. Connect leads from accessory
packages such as tachometer,
pressure transducer and high temp cut-
off to the designated positions on the
back panel of the 4848 Controller.
