PIN-TRACK 7T2287 - Caterpillar

Problem 1The pump will stop pumping when the number of successive errors are exceeded. The standard is ten times but can be changed.Probable cause
The pump turned off because the pressure switch did not turn on during a sequence of successive cycles. Note: The pump is looking at the change of signal of the pressure switch. The pump is not looking at the switch status.SolutionThe switch for the grease pressure did not turn on due to one of the following reasons:
The primary grease line contains a leak.
External problem to check (i) Broken primary grease line "(A or B)" (ii) An O-ring is damaged or missing causing a leak at one of the following:
The metering unit
The switch for the grease pressure
The blind plug
Internal problem to check (i) There is an internal leak in the metering unit or in the switch for the grease pressure.
Air is in the system. Automatic Lubrication System Air - Purge, "Purging the Lubrication Lines for the Automatic Lubrication System"
There is a wiring defect between the pressure switch and the pump.
The pressure switch is broken. Electrical System - Test, "Check for the Lube Pressure Switch"
The 5/2 solenoid valve is broken. Electrical System - Test, "Check for the Pump and the 5/2 Magnetic Valve". If a fault is found in either the pressure switch or the solenoid valve, replace the entire pump.
The viscosity of the grease is wrong or the surrounding temperature is too low. Problem 2There is no lubricant at the grease points and no reports regarding malfunctions have been given.Probable cause
Problem with the voltage supply for the pump
There is a problem with supply to pin (3) on the pump control or with the "Command Signal Inverted (CSI)" setting.
Information for operator
Pin (3) on the autolube pump is supplying the command signal to the pump.
The operator has a "Command Signal Inverted (CSI)" setting which can be modified with the TWIN GINA software.
The pump control has an interval timer. The interval timer counts down to the next grease interval:
- Pin (3) is powered and "CSI" setting equals "0 or NO".
- Pin (3) is not powered and "CSI" setting equals 1 or YES.
The "Command Signal Inverted (CSI)" setting equals Yes or 1 for Articulated Truck because pin (3) is not powered.
The "Command Signal Inverted (CSI)" setting equals NO or 0 for the Medium Wheel Loaders because pin (3) is powered.
Installed new pump
The "Command Signal Inverted (CSI)" setting equals No or 0 for Medium Wheel Loader.
The "Command Signal Inverted (CSI)" setting equals Yes or 1 for Articulated Truck.Solution
Check if supply voltage does not drop immediately after the start of the grease interval. Voltage drop could be related to voltage drops over cables, connections, or low battery voltage.
Check the "Command Signal Inverted (CSI)" setting to verify the setting. If the setting is in error, change the setting.
The "Command Signal Inverted (CSI)" setting equals NO or 0 for Medium Wheel Loader.
The "Command Signal Inverted (CSI)" setting equals Yes or 1 for Articulated Truck.
Same as the previous point Problem 3There is insufficient lubricant at
