Safety Information
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of
correct voltage and current handling capability.
2. Ensure that the equipment is connected to
electrical service according to local national
electrical codes. Failure to properly connect may
create a fi re or shock hazard.
3. For continued protection against possible
hazard, replace fuses with same type and rating
of fuse.
4. Disconnect from the power supply before
maintenance or servicing.
To avoid personal injury:
1. Do not use in the presence of fl ammable or
combustible materials; fi re or explosion may
result. This device contains components which
may ignite such material.
2. Refer servicing to qualifi ed personnel.
Intended Usage
This controller has been designed for use with Parr
Pressure Vessels and Reactors. It has been designed, built, and tested to strict physical and electrical standards. However, it is the user’s responsibility to install and operate it in conformance with local
pressure and electrical codes.
If the instrument is used in a manner not specifi ed
by Parr Instrument Company, the protection provided by the equipment may be impaired.
Establish training procedures to ensure that any
person handling the equipment knows how to use it
properly.
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.

Installation
General Instructions
Valve Controllers
Set the controller near the reactor on a sturdy bench
or table where there is convenient access to an
electrical outlet capable of carrying the appropriate current. Leave a space of at least twelve inches
between the controller and the reactor so that the
controller will not be affected by radiant heat.
Attach the supplied power cord to the POWER INPUT connector located on the rear panel of the 4877
Valve Controller.
Front Panel
Plug the power cord into a properly grounded electrical supply outlet.
Main power switch
This switch located on the front panel will cut off
power to the controller.

Valve Controllers
Air Supply
Connect a dry air supply to the 1/4” Male Tube con-
nector provided on the rear panel of the 4877 Valve
Controller. The operating pressure of the air supply
is determined by the air actuated valves supplied
with your reactor system. The controller and the
supplied tubing are limited to a maximum working
pressure of 105psig.
Warning:
The controller and supplied tubing are
rated to a maximum working pressure of
105psig.
Reactor Outlet
There are up to 12 air outlets provided on the rear
panel of the 4877 Valve Controller. Each outlet is
numbered 1-12. Use the tubing supplied to connect the corresponding air actuated valve to the
appropriate outlet connection. This is unique with
each system but can be determined by the IO map
provided on the Process Controller CD supplied with
your particular reactor system.
Valve Control
The VALVE CONTROL connection on the rear panel
of the 4877 Valve Controller is to be connected to the
Process Controller provided with your system using
the supplied control cable.
Protective Fuses
Main fuses are mounted on the back panel of the
valve controller. These fast acting, 250VAC, 3 amp
fuses are intended to protect the controller and supply in case of a fault condition.
Warning:
Unplug unit before servicing. For continued protection against possible hazard,
replace fuses with same type and rating of
fuse.
