7.17.2 Changing the State-Of-Charge-Dependent Generator
Request
Significance of the SOC limiting values:
If the battery reaches the lower SOC limiting value, the generator management requests the
generator. If the battery reaches the upper SOC limiting value during recharging, generator
management resets this generator request.
1. Switch to installer mode (see Section 7.5).
2. Select the 235.03 GnSocTm1Str parameter and set it to the lower SOC limiting value.
3. Select the 235.04 GnSocTm1Stp parameter and set it to the upper SOC limiting value.
4. Set the 235.07 GnTm1Str and 235.08 GnTm2Str parameters to the same value, e.g. both
to 000000. This deactivates the time-dependent generator request.
7.17.3 Setting Time-Dependent Generator Request
Significance of the start times and SOC limiting values:
The time-dependent generator request divides the day into two intervals. For each interval, you set the
conditions that apply for generator request (see Section 7.7"Setting Time-Dependent
Functions",page89). For example, you set the generator not to start at night. This ensures that the
noise pollution caused by the generator takes place during the day where possible.
Both intervals have a lower and an upper SOC limiting value each. If the battery reaches the lower
SOC limiting value, the generator management requests the generator. When the battery reaches the
upper SOC limiting value during recharging, generator management resets this generator request.
The following settings are possible for the SOC limiting values:
• The lower SOC limiting value is smaller than the upper SOC limiting value.
The generator is requested during this interval depending on the state of charge.
• The lower SOC limiting value is greater than or equal to the upper SOC limiting value.
The generator is not started depending on the state of charge. In this interval the other settings
for generator requests apply – e.g. load-dependent generator request.
