Users will have to study the schematic diagram given in the manual to understand the diagnostic display lights in the front side of the TVD 1.2-15-03 power supply module. There are four sets of Red and Green lights vertically placed and each has a function to do. While in operation, if there are situations of overcurrent or if the temperature or voltage exceeds the limits set, the Red LED light will glow. You will then be alerted of the anomaly and it can be taken care of.
The manual has a complete breakdown of the information on these diagnostic display lights. Bosch Rexroth advises that you could keep a spare module ready for such problematic situations. Just pull the TVD 1.2-15-03 power supply module out and insert the spare one and carry on with the production activity. This is a convenience you enjoy with the module-type build of these parts. If you don’t want to stock a replacement power supply module, the manufacturer may send you one on immediate notice and then you may send the faulty part for repairs.
Buyers will have to note that an appropriate braking resistor has to be in place since these power supply modules are not power-regenerative by design. This TVD 1.2-15-03 power supply will come fitted with the NAM 1.2-15 Filter module as well. The sizing of these filters is done at the factory.
