Selecting the HTG mode
1. Navigate to Setup → Advanced setup → Application → Tank calculation → HTG
2. Go to the
HTG mode
parameter (→ 206) and select the mode according to the
following table.

Assigning the P1 (bottom) pressure sensor
1. Navigate to : Setup → Advanced setup → Application → Tank configuration
→ Pressure
2. Go to the
P1 (bottom) source
parameter (→ 181) and select the device from
which the bottom pressure is obtained.
3. Go to the
P1 (bottom)
parameter (→ 118) and check whether the indicated
pressure matches the actual pressure at the P1 position. If necessary, the indicated
pressure can be corrected by the
P1 offset
parameter.
4. Go to the
P1 position
parameter (→ 182) and enter the distance from the datum
plate to the P1 sensor.
5. Go to the
P1 abs / rel
parameter (→ 182) and specify whether the P1 sensor
measures an absolute or a relative pressure.
Assigning the P2 (middle) pressure sensor
This procedure is only required for the following HTG modes:
• P1 + P2
• P1 + P2 + P3
1. Navigate to Setup → Advanced setup → Application → Tank configuration → Pressure
2. Go to the
P2 (middle) source
parameter (→ 183) and select the device from
which the middle pressure is obtained.
3. Go to the
P2 (middle)
parameter (→ 118) and check whether the indicated
pressure matches the actual pressure at the P2 position. If necessary, the indicated
pressure can be corrected by the
P2 offset
parameter (→ 184).
4. Go to the
P1-2 distance
parameter (→ 184) and enter the distance between the
P1 and P2 sensors.
5. Go to the
P2 abs / rel
parameter (→ 184) and specify whether the P2 sensor
measures an absolute or a relative pressure.
