Pneumatic System
The pneumatic system is contained within the actuator’s sheet metal enclosure. Refer to
Figure 5.1
2000X Actuator Pneumatic System.
The pneumatic system is contained within the actuator and the remote pneumatics box.
The system consists of:
1. a primary solenoid valve,
2. a cooling solenoid valve,
3. an air cylinder,
4. a pressure regulator,
5. an air-pressure gauge
6. a down speed flow control valve
The horn’s rate of descent (downspeed) is adjusted at the front of the actuator using the
Downspeed control knob. The rate of ascent is fixed.
CAUTION
Do not loosen the top hex-headed nut. Damage to the mechanical
stop can result.
NOTICE
Turning clockwise will increase the stroke length; turning counter-
clockwise will shorten the stroke length. Adjustment is approximately
0.04-inch (1 mm) per rotation.
