Security; Using Units Or Percent (%); Parameters Types - Siemens HydroRanger 200 Instruction Manual

Security

The Lock parameter P000 secures the HydroRanger 200 against parameter changes via
the handheld programmer. The unit can still be put into PROGRAM mode when locked,
and parameter values can be viewed, but no parameter values can be changed.
When P000 is set to 1954, programming is enabled. To disable programming, enter
another value.
P000 (1954) is a fixed value password. Therefore, you should use other means to secure
the HydroRanger 200 if security is a concern.
Simulation
P000 Lock also controls how simulations affect control relays. By default, control relays
are unaffected by simulation levels. But if P000 is set to –1, they react to the simulated

level. See

Using Units or Percent (%)

Many parameters can be viewed either in measurement units (P005) or as a percentage.
View the parameter and then press MODE
The LCD shows the selected measurement type, either units (m, ft) or percentage (%).
6 relay model only:
Percentage is also available when showing flow and volume with 100%, based on the
parameter that defines the maximum.

Parameters Types

View Only Parameters
Parameter values indicating status only. They cannot be altered.
Global Values
Parameter values common to all inputs and outputs on the HydroRanger 200.
When a global parameter is accessed, the index display automatically disappears. When
a non-global parameter is accessed, the index display reappears showing the last index
number.
