Hydrostatic Tester Plan
Current State:
1.- Relace clamping plates to original plates
2.- Attach needle valve.
3.- Connect safety interlock/Emergency Stop
4.- Connect transformer (M. Barlett).
5.- Attach feedback tube.
Phase One (Hydraulic):
1.- Replace mechanical/analog controls and readouts.
2.- Program PLC:
- Valve diameter and hydro pressure.
- Determine clamp force.
- Allow operator to manually jog ram to position before pressure (electric motor).
- Button to depressurize.
3.- HMI:
-Hydraulic Pressure readout.
Phase Two (Hydro):
1.- Replace mechanical readouts and controls.
2.- Add Hydro to PLC program:
- Fill valve.
- Remove air bubbles.
- Time test.
- Drain.
3.- HMI:
- Hydro Pressure readout.
- Timer readout.
Inputs/Outputs:
Inputs:
- Jog Open.
- Jog Close.
- Pressurize.
- Depressurize.
- Pressure input (could be valve size and test pressure).
 Pressure Gauge.
Outputs:
 Relay to Electric motor.
 Valve to pneumatic motor.
 Open drain.
 Close drain.
 No-feedback solenoid open and close.
 Directional solenoid open.
 Directional solenoid close.
- Pressure readout.
