Operation

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 parameters P925–P927 on page 208 for running a simulation.

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 to toggle between units and percentage.

The LCD shows the selected measurement type, either units (m, ft) or percentage (%).

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.

Default Values

Parameter default values are indicated with an * in the parameter tables.

P000 Lock

The asterix identifies 1954 as the default value.
