Supply Air
Using the supplied 3/8" OD tubing connect the
Supply air inlet to a source of clean, dry factory
air having an operating pressure of 80 psi (5.5
bar) minimum and 110 psi (7.6 bar) maximum.
For optimal speed control response ensure the
supply air is at least 100 psi minimum operating
pressure.
Control Output(s) (CL1-CL6)
Using the supplied 5/32" OD tubing, connect the
control output(s) to the pilot signal port(s) of the
volume booster(s) which are supplying turbine air
to the rotator(s). It may be necessary to install
a 5/32" adapter fitting in the volume booster pilot
port. DO NOT replace this tubing with larger
diameter tubing or speed response may be ad-
versely affected.
Enable Input(s) (EN1-EN6)
The enable input is an interlock which must be
made active in order for speed control to occur
on a given channel. This can be done pneu-
matically by using the enable inputs on the right
side of the control panel or electrically by using a
remote switch across the enable input contacts
(see Electrical I/O later in this section).
For pneumatic activation, connect the supplied
1/4" OD tubing from the activation source to the
Enable input on the right side of the control panel.
Typically, the pneumatic Enable input is used
to interface with an Ransburg Air Logic Panel.
(See the appropriate service manual for further
information.)
Optional Brake Control Output(s)
(BR1-BR6) (Bells Only - See Figure
3)
Using the supplied 1/4" OD tubing, connect the
brake control output(s) to the pilot air input(s) of
the supplied brake valve assembly(s). Using the
supplied 3/8" OD tubing, connect the output port
of the brake valve assembly(s) to the brake air
input of the bell applicator(s).
When a lower speed is requested than the speed
the bell is currently spinning at, the brake valve will
turn on and apply air against the rotator vanes to
assist in a more rapid transition to the lower speed.
Once the new speed is reached, the brake valve
will turn off. Additionally, it is possible to configure
the system so that the brake turns on when the bell
speed is disabled, to assist in bringing the bell to
a full stop more quickly. This is explained further
under "Dip Switch Settings" in the "Installation "
section of this manual.
