Power On Load - gefran GFW ADV Configuration Manual

POWER ON LOAD

Power on the load in each zone is read in variable Ld.P and the corresponding energy value in variables Ld.E1 and Ld.E2.
These energy values show the value accumulated since the first power on or since the last reset (commands at bits 114 and
115); non-volatile memory is updated at power off.
Load impedance in each zone is read in variable Ld.I.
If zone 1 has a 3-phase load, variable Ld.P.t shows power and Ld.I.t total impedance, the corresponding energy value in va-
riables Ld.E1.t and Ld.E2.t.
Note that for loads such as IR lamps, impedance can vary greatly based on the power transferred to the load.
