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).
4.4 Operating table cannot be operated using the IR remote control
- Check the system setting of the IR transmitter and IR decoder.

- If there is still no reaction, check the transmission power of the IR remote control using the IR tester.
- Test the charging station of the IR transmitter using the IR tester.
- Test the operating table function with another IR transmitter.
- Test the function of the IR transmitter previously used with another operating table.
- Test the operating table function with the IR tester.
- For further details, refer to the instruction manual of the IR tester and the technical
description “IR remote control unit “ for hydraulic operating tables (instruction manual).
