4.3 Red light on the control unit display - although the batteries have been charged for an extended
period of time (8 to 15 hours)
Test the batteries, the battery charger as well as the motor.
Test the transformer: If the battery charger stops charging the batteries before they are completely
charged, the transformer gets too warm and the NTC (connection A4 and A7) therefore interrupts the
battery charger.
For testing, detach the NTC connections (A4, A7).
If the battery charging has now improved, exchange the transformer -> too fast overheating.
For 1131.01 with 2 batteries: reduce the working pressure from 130 to 100 bar and, if this is not enough,
modify the battery charger (additional information can be obtained at the Rastatt manufacturing plant).
