BRACKET 9V9642 - Caterpillar

Set The Number Of Pumps : Select parameter "2", if two pumps are required. Two pumps are required in order to send hydraulic oil to the hammer through the combined function auxiliary line. See "Setting The Number Of Pumps".
Set The Pressure Of The Circuit For The Hammer : Enter the pressure that is required for the hammer. The pressure that is required for the hammer can be found in the specifications for the hammer. For example, if the pressure setting for the hammer is 17700 kPa (2567 psi), the formula is listed: 1 MPa () equals 1000 kPa () and 17700 kPa () divided by 1000 equals 17.7 MPa (2567 psi). Enter 18 MPa (2610 psi) by rounding off the result. See "Setting The Circuit Pressure".
Set The Flow For The Hammer Mode : Enter the required pump flow for the hammer. See "Setting The Pump Flow". The required pump flow can be found in the specifications for the hammer. Refer to item 6 when the speed of the hammer is a problem.
Set The Parameter That Requires High Flow To A Hammer : See the following information for a hammer that requires a flow rate of 250 L/min (66 US gpm) or more through the combined function auxiliary line:
Set the number of pumps to be used: Enter "1". See "Setting The Number Of Pumps".
Set the pressure for the hammer : Enter the pressure that is calculated by using the following formula:
For example, if the pressure setting for the hammer is 17700 kPa (2567 psi), the formula is listed: 1 MPa () equals 1000 kPa () and 17700 kPa () divided by 1000 equals 17.7 MPa (2567 psi). Enter 18 MPa (2610 psi) by rounding off the result. See "Setting The Circuit Pressure".
Set the pump flow to the hammer : Enter the flow that is calculated with the following formula:
The required flow that is described in the specification for the hammer is multiplied by 1/2. See "Setting The Pump Flow".

Preset The Hammer Mode : Select the "U2" Mode when a hydraulic hammer is used with auxiliary lines for the flow of two pumps. The maximum pump flow will be sent to the hammer, if the operator selects a work mode that is not "U2" resulting in damage to the hammer. This problem can be avoided by using a special security code to reset the preset of the hammer mode from the OFF position to the ON position.After this change is made to the software, the correct flow will be sent to the hammer when the pedal for the hammer is activated. The settings of the work mode do not affect this procedure.Note: The machine is set in the OFF position at the factory.
Access the service mode. Then, enter the service code "080251".
When "10" or "80" is display on the monitor, enter the new service code "89" on the character display.
The slow mode switch (25) is pressed in order to move the character to the right of the character
