Pressure Settings

The pump has two methods for limiting the pull / advance pressure to the placing tool and further pressure relief valve for
limiting the return pressure. The process below explains how to correctly set these pressure limits.
Pull / Advance Pressure Settings:
IMPORTANT – THE PULL / ADVANCE PRESSURE RELIEF VALVE SETTING MUST NOT EXCEED 550 BAR.
IMPORTANT – THE HIGH PRESSURE ('HI PRESS') SETTING MUST NOT EXCEED 510 BAR WHEN CONNECTED TO
THE PLACING TOOL.
•
Disconnect the placing tool and hoses from the pump.
• Connect the unit to the power supply and switch on, as described on pages 11 and 12.
•
Activate the LOCAL mode by displaying the 'LOCAL' menu and toggling the setting to 'ON' using the Arrow buttons.
Save the setting by pressing the MENU button once.
•
Display the 'HI PRESS' menu and adjust the value to 600 BAR using the Up Arrow button. Save the setting and
return to the 'AVDEL' display by pressing and holding the MENU button for 2 seconds.
•
Turn on the pump by pressing the MOTOR On/Off button.
• Press and hold the Up Arrow. This will switch the valve solenoid to the pull / advance position and the relief valve
pressure setting will be displayed on the LCD screen. Releasing the Up Arrow will switch the valve solenoid back to
the return position and the return relief valve pressure will be displayed on the screen. The motor will then switch off
after 5 to 20 seconds and the solenoid valve will switch to the idle position.
•
Loosen the relief valve locking nut and turn the relief valve control handle counter-clockwise until there is a light drag
when turning, this will decrease the pull / advance pressure. Refer to the illustration below.
