10.1 PROBLEMS WITH THE ELECTRONIC BOARD
In case of failures in the electronic board inside the control panel, a pumping job may be completed by manual operation.
You can control the pistons' pumping and sucking operations using the small levers (m1-m2) on the side of the control panel.
Open the side doors on the casing from the control panel side so that you can monitor the alternating lighting up of the LEDs
on the S-valve and the lubrication water tank.
- The LEDs on the two sensors next to the jacks controlling the S-valve show which of the two pistons is currently pumping.
- Two more sensors (and respective LEDs) on the water tank show when the relative pumping piston ends its suction phase
and is ready to start the pumping phase.
When the LED (FIG. 71-REF. 1) is on, meaning that the piston is ready for pumping, move the lever (m1) to position 1.
When the LED (FIG. 71-REF. 3) turns on the pumping phase is completed.
Now move the lever (m1) to position 2 to switch the position of the S-valve. LEDs (FIG. 71-REF. 2) and LED (FIG. 71-REF. 4)
will light up.
Move on to the lever (m2) and follow the same procedure: position 1 starts the pumping and position 2 switches the S-valve.
Proceed until the hopper is empty.

10.2 PUMPING SYNCHRONISM RESET
Perform the following operations if the pumping piston's synchronism is lost.
- stop pumping,
- ensure the hopper unload door and grid are closed;
- act on the m1 lever bringing it to position 2, holding it in position for a few seconds,
- carry out previous operation for the m2 lever also,
- re-start pumping.
Immediately inform Turbosol service of the problem.
