After having the following parameters properly adjusted, enable the protection function for primary side of a transformer.
• Determination set value in case of a break on the secondary side of the transformer (a)
[Factory set value: 70 % of computed heater current value]
• Output limiter setting in case of a break on the secondary side of the transformer (h)
[Factory set value: 20.0 % of phase angle]
• Soft-start time in case of break on the secondary side of the transformer (u)
[Factory set value: 0.1 seconds]
