Siemens F01034

What the Fault Means

Fault: Units changeover: Calculation parameter values after reference value change

Likely causes

• The change of a reference parameter meant that for an involved parameter the selected value was not able to be recalculated in the per unit representation
• The change was rejected and the original parameter value restored
• Fault value (r0949, parameter): Parameter whose value was not able to be re-calculated
• See also: p0304, p0305, p0310, p0596, p2000, p2001, p2002, p2003, r2004

Solution and Safe First Checks

1. Select the value of the reference parameter such that the parameter involved can be calculated in the per unit
2. Technology unit selection (p0595) before changing the reference parameter p0596, set p0595 = 1.

Safety: do not work inside the panel without isolating the power; if unsure, consult a qualified technician.
