Checking Volume Characterization [6 Relay Model]; Checking Ocm Flow Characterization [6 Relay Model] - Siemens HydroRanger 200 Instruction Manual

3. Press the ARROW
chart on page 84. The maximum rate is 4% of Span / second.
The effect of the ARROW key is determined by the state (rate of rise or fall) immediately
before the key is pressed.
Action State (prior to pressing key)
Stop
Rise at 1% of Span / second
Rise at 4% of Span / second (max.)
Press
Fall at 1% of Span / second
Fall at 4% of Span / second
Stop
Rise at 1% of Span / second
Press
Rise at 4% of Span / second (max.)
Fall at 1% of Span / second
Fall at 4% of Span / second (max.)
When the level rises to 100% or falls to 0%, it reverses direction at the same rate.

Checking Volume Characterization [6 relay model]

To confirm universal volume calculations (P050 = 9, 10) are correct:
1. Go to P920.
2. Key in a level associated with a known volume.
3. Press ENTER
4. Check the returned volume against the manufacturer's chart.
5. Change parameters P054 and P055, as required.
6. Repeat steps 2 to 5 until the volume curve is verified.
Checking OCM Flow Characterization [6 relay
model]
To confirm universal flow calculations (P600 = 4, 5) are accurate:
1. Go to P925.
2. Enter a level with a known flow.
3. Press ENTER
