Installation, Operation, and
Maintenance Instructions
Type 600
Volume Booster
INSTALLATION
The ControlAir Type 600 ratio relay, volume booster is designed for air service only.
Maximum supply pressure is 250 psig. Maximum signal pressure is 150 psig for the 1:1
ratio; 75 psig for the 1:2 ratio; 50 psig for the 1:3 ratio, and 25 psig for the 1:6 ratio.
Operating temperature is -200F to 1600F.
Prior to installation clean all air lines to remove dirt and other debris. Apply a small
amount of compound to the male threads only and install the volume booster so that the
flow is in accordance with the IN and OUT ports as marked. The signal port is tapped
into the volume booster through the 1/4" NPT connection on top of the unit. Make sure
that all connections are tight and that the exhaust vent on the side of the volume booster
is not blocked. The volume booster can be mounted in any position without effecting
operation.
The use of a filter to remove dirt and liquid in the air line ahead of the booster is
recommended for consistent performance. If an air line lubricator is used, it should be
located downstream of the Type-600.
OPERATION
Apply an input signal to the signal port. There are no manual controls on the volume
booster.
OPTIONAL FIXED NEGATIVE BIAS
The Type 600 is available with an optional 4 + 1 psig (0.3 + 0.07 BAR) less than the
signal pressure.
This option allows zero output when utilizing I/P transducers (such as the ControlAir
Type 500X) that typically only are capable of providing pressures down to 3 psi. Note
that the negative bias has a tolerance of + 1 psi. This means that the actual bias will
range from -3 psi to -5 psi. Use the zero adjustment of the I/P to reach desired setting.
MAINTENANCE
Occasional attention may be required due to the accumulation of foreign material in the
instrument. The regulator is easily disassembled without removal from the line. Before
this is done, however, shut off valve upstream of the volume booster to prevent escape
of air when disassembled. Remove the two No. 8-32 screws on the bottom of the unit
and pull out the pintle assembly. Wash inner valve assembly with solvent, exercising
care to avoid damaging diaphragms and valve facings. Avoid such solvents as acetone,
carbon tet, trichloroethylene. Replace assembly carefully.
If further attention is required, repair kits and replacement parts may be purchased.
The vent hole in the bonnet should be kept clean. A slight flow of air through this hole is
necessary for the proper operation of the volume booster.
