7.14.4.1 Simulating a fixed level
1. Set the desired fixed level value in Level Value (3.4.1.2.) (Page 258).
2. Set Ramp (3.4.1.3.) (Page 259
) to Disabled.
3. Enable Pump Activations (3.4.3.) (Page 259) if desired (see Pump relay behaviour during
simulation (Page 154)).
4. Set Level Simulation Enable (3.4.1.1.) (Page 258
) Enable to Enabled to start level
simulation.
Set Level Simulation Enable (3.4.1.1.) (Page 258) Enable to Disabled when you wish to stop
level simulation.
7.14.4.2 Simulating a changing level
1. Set the desired starting level value in Level Value (3.4.1.2.) (Page 258).
2. Set Ramp (3.4.1.3.) (Page 259) to Enabled.
3. Set Ramp Rate (3.4.1.4.) (Page 259
) to the desired speed, For example: Medium.
4. Enable Pump Activations (3.4.3.) (Page 259) if desired (see Pump relay behaviour during
simulation (Page 154)).
5. Set Level Simulation Enable (3.4.1.1.) (Page 258
) to Enabled to start level simulation.
The simulated level will initially begin ramping up from Level Value (3.4.1.2.) (Page 258)
(increasing level). When the level rises to 100% or falls to 0%, it reverses direction at the
same rate.
Set Level Simulation Enable (3.4.1.1.) (Page 258
) to Disabled when you wish to stop level
simulation.
7.14.4.3 Simulating Discrete Inputs
1. Enable Pump Activations (3.4.3.) (Page 259) if desired (see Pump relay behaviour during
simulation (Page 154)).
2. Set the discrete input to be simulated (Discrete Input 1 (3.4.2.1.) (Page 259), Discrete
Input 2 (3.4.2.2.) (Page 259) or both) to one of the following:
– ON: the discrete input is simulated to be on
– OFF: the discrete input is simulated to be off.
Set parameter(s) for DI to be simulated (Discrete Input 1 (3.4.2.1.) (Page 259) and/or
Discrete Input 2 (3.4.2.2.) (Page 259)) to Disabled if you do not wish to simulate a discrete
input, or to stop DI simulation that is currently running.
