Pump Relay Behaviour During Simulation - Siemens SITRANS LUT400 Operating Instructions Manual

The following functions will not respond to the simulated value when in simulation mode:
• Fault Conditions - The LUT400 will never enter the Fail-safe state when in simulation
mode. For further details see
• Backup Level Override - If a Backup Level Override switch is configured and it lies
within the simulated Level range, it will not be simulated. To simulate a Backup Level
Override, simulate the discrete input. See
• Totalizing of OCM Flow - Totalizing of flow (OCM applications) does not occur during
simulation. The OCM Daily Totalizer (
increase in value during simulation.
• Totalizing of Pumped Volume - Totalizing of pumped volume does not occur during
simulation if
simulation, the material pumped will be totalized (
• External Sampler - The external sampler, if configured, will click at its timeout
interval when in simulation mode (see

This parameter has two possible values:
Disabled: Pump relays are not activated in simulation (default value)
Enabled: Pump relays are activated in simulation

corresponding relay icons will turn ON, but the relays will not energize). If

is Enabled, the relay icons will turn ON, and the relays will energize.
WARNING:
being damaged during simulation, or if the pumps have been locally disabled
through some other means.
Notes:
• If the pump relays are configured to physically activate in simulation mode, then any
time activated will be recorded in the pump Run Time parameter (see
on page 203.).
• If a pump start delay has been programmed for the device (
Starts
), it will be respected in Simulation mode.
