• The Snapshot function, available with Guardian NT (sold separately*), is used to sample the load of all dimmers in the system
and remember the load for future comparison.
• During polling, the load connected to each dimmer is compared to the sampled load and any variation that is reported.
• Setup load comparison by selecting
Email / Log File
on the Setup menu.
:
• The dimmer cannot measure the load unless the dimmer is ON.
• In order to store accurate loads in the snapshot, each dimmer must have been set to a level greater than 10% for at least 60 seconds.
• All dimmers do not need to be on together, however, they must be on for a period prior to taking the snapshot.

• The Total Load function, available with Guardian NT (sold separately*), will display an approximation of the total load on each
phase of the system.
• Total Load assumes a properly wired, three-phase electrical system.
• The load is calculated by adding the load on each individual dimmer.
:
• The dimmer cannot measure the load unless the dimmer is ON.
• In order to store accurate loads, each dimmer must have been set to a level greater than 10% for at least 60 seconds.
• All dimmers do not need to be on together, however, they must be on for a period prior to displaying the Total Load.
