2. DESCRIPTION
2.1. Fun tional Des ription
The following describes the function of the one–valve press beyond the description of the basic press covered
in 409–5128.
In the static condition, the cam switch (S8) is actuated OPEN by the cam on the transmission and the solenoid
valve is de–energized, thus supplying air through the top front port and exhausting return air through the
bottom front port and muffler to the atmosphere.
The press cycle begins the moment the foot switch (S3) is depressed. At approximately 4 degrees of the press
flywheel rotation, the cam switch is de–actuated which CLOSES the circuit to energize the solenoid valve. This
diverts air pressure out of the bottom front port of the solenoid valve and exhaust air back through the top front
port and muffler to the atmosphere. The solenoid valve remains energized as the press ram bottoms and
returns near the top of the upward stroke. At this point, the cam again actuates the cam switch and the circuit
is OPENED to de–energize the solenoid valve as the press returns to the static condition. This completes a
cycle of operation.
The purpose of the motor ON–OFF switch (S4) is to provide a means of stopping the motor for hand–cycling of
the press during setup and adjustments of the special machine or miniature applicator. With this switch OFF
and the main power switch (S2) ON, the solenoid valve is energized and de–energized during hand–cycling of
the press in the same manner as during normal operation.
2.2. Ele tri al Des ription
The electrical system is basically the same as the basic machine covered in 409–5128 except with the addition
of the solenoid valve (L2), cam switch (S8), and motor on–off switch (S4) as indicated in Figure 2.
3. RECEIVING INSPECTION AND INSTALLATION
All receiving inspection and installation information contained in 409–5128 is applicable to the one–valve press.
The one–valve press must be installed as described in 409–5128, and the plug must be connected to an
adequate and convenient electrical outlet with 115 Volts, 60 Hz, single phase, and a minimum continuous air
supply of 620 kPa [90 psi] connected to the sleeve valve. The sleeve valve must be OPEN, and the main
power switch (S2) and motor ON–OFF switch (S4) must be ON. With both switches ON, the motor runs
continuously and electric power is supplied to the cam switch (S8).
4. OPERATION
All operating information contained in 409–5128 is applicable to the one–valve press.
