Pressure Relief Procedure

Pressure Relief

Procedure

Kit Installation

System pressure can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.

1.

Set START/STOP switch to STOP.

2.

Push in SECURE DISABLE switch.

3.

Open the back pressure regulator and all fluid drain valves in the system, having a waste container ready to catch drainage. Leave open until you are ready to pressurize system again.

4.

Check that pressure gauges on fluid supply and return lines read zero. If gauges do not read zero, determine cause and carefully relieve pressure by

VERY SLOWLY loosening a fitting. Clear obstruction before pressurizing system again.

1.

Jog the motor to bring the stand side lower to the bottom of its stroke.

2.

Relieve pressure, page 2.

3.

Shut off electrical power to the unit.

4.

See F IG . 1. Remove two screws (12) and the cover

(A).

Pressure Sensor Calibration Information (non-ACS systems)

Pressure Sensor

Calibration Information

(non-ACS systems)

NOTE: To calibrate the transducer in systems using the

Graco ACS Module, see the ACS manual 3A0006.

Pressure sensor information (Pr 20.34, 20.35, and

20.36) for your system must be keyed into the Variable Frequency Drive before system start-up.

To prevent accidental change of pressure sensor calibration parameters, they are locked by Pr 20.16. To enter calibration parameters, perform the following steps: a.

Set Pr 20.16 to 777, to unlock pressure sensor parameters.

b.

Enter calibration parameters Pr 20.34, 20.35, and 20.36.

c.

Set Pr 20.16 to 0 to lock pressure sensor parameters.

Calibration Parameters from the label:

Pr 20.34 – Zero Calibration

Pr 20.35 – Calibration Pressure

Pr 20.36 – High Calibration

Pressure Transducer

Calibration Procedure

(non-ACS systems)

E-Flo pressure sensor must be calibrated against an instrument grade High Precision Pressure Transducer, which should be installed near the E-Flo pressure sensor.

1.

Ensure that the High Precision Pressure Transducer calibration is up to date.

2.

Set Pr 20.16 to 777, to unlock pressure sensor parameters.

3.

Calibrate Low Pressure Point as follows: a.

Ensure that system is not pressurized. Calibration instrument pressure reading should be 0 psi. b.

Use Keypad to navigate to Pr 20.33; monitor its reading for 5 – 10 seconds to determine its average value. Make a record of it.

c.

Navigate to Pr 20.34 and enter the recorded average value of Pr 20.33.

4.

Calibrate the High Pressure Point as follows: a.

Pressurize the system to 250 – 275 psi.

Do not exceed pressure rating of the system! If system is rated to a pressure lower then 250 psi, use maximum allowable rated pressure. Refer to Operation

Manual 311593.

b.

Keep the system pressurized and ensure that pressure does not fluctuate. c.

Take a pressure reading from the calibration instrument and make a record of it.

d.

Navigate to Pr 20.35 and enter the recorded system pressure.

e.

Navigate to Pr 20.33; monitor its reading for

5-10 seconds to determine its average value.

Make a record of it.

f.

Navigate to Pr 20.36 and enter the recorded value of Pr 20.33.

5.

Set Pr 20.16 to 0 to lock pressure sensor parameters.

6.

Verify pressure calibration.

a.

Relieve system pressure.

b.

Navigate to Pr 20.31 and verify that its reading is within the range of 0-3 psi.

c.

Pressurize the system to about 100 psi. Verify that reading of Pr 20.31 is within +/- 2.5 psi of the system pressure.

d.

Pressurize system to about 250 psi. Verify that reading of Pr 20.31 is within +/- 2.5 psi of the system pressure.
