Unpacking

Unpacking the Product

The Dynastarr pump module was carefully packaged for shipment by Graco. When the package arrives, perform the following procedure to unpack the units:

1.Inspect the shipping box carefully for shipping damage. Contact the carrier promptly if damage is discovered.

2.Unseal the box and inspect the contents carefully. There should not be any damaged parts.

3.Compare the packing slip against all items in- cluded in the box. Any shortages or other inspec- tion problems should be reported immediately.

4.Store the box and packing materials in a safe place for future use. Graco recommends that all packing materials be saved in case the unit needs to be shipped again.

Pump Module Overview

Pump Module Capabilities

The Pump Module provides lubricant flow and pres- sure to operate a single line parallel automatic lubrica- tion system. The module requires a hydraulic power Supply and a timed signal from a lubrication controller. Based on these signals, the pump module provides lubricant flow and pressure to operate the injectors and vents the injector system to reset the injectors.

Pump Module Operation

Pump Module Operation performs these cycles:

1.Upon receiving a signal from a 24 volt lubrication controller, the 3–way solenoid valve (Fig. 3, item F) opens, starting the pump (D) and closing the vent valve (U).

2.The pumps builds pressure until the pressure switch in the system sends a signal to the timer, ending the cycle, or the pump stalls.

3.The timer terminates the 24 volt signal to the 3–way solenoid valve (F).

4.The 3–way solenoid valve (F) closes, stopping the pump and opening the vent valve (U).

5.The system lubricant pressure bleeds back through the vent valve (U) into the reservoir (P).

6.The pressure reducing valve (PRV) (item S) and flow control valve (FCV) (item N) control the pump output pressure and cycle rate.
