values in the measurement buffer.
• Reset
Reset deletes the measurement buffer content.
• Save
Entering save saves the pending measurement values (e.g. burner period) in the corresponding meas-
urement value buffer.
• “Value name”
At least one value name must be set up (e.g. burner period).
NOTE: It is necessary to at least link the save input and a “value input”.

4.3.4.7 Energy Analyser D550D - Residual current monitoring (RCM)
Monitoring residual current by measuring residual current in electric systems is a precaution used in preven-
tative maintenance. Insulation faults caused by fault currents can be recognised early using residual current
monitors(RCM)asspeciedinDINEN62020(VDE0663).
• Residual current monitoring is not a substitute for the recurring inspections to be carried out in accord-
ance with DIN VDE 0105!
• Alternating currents and pulsing direct currents are monitored in accordance with
EN 62020:1998+A1:2005.
Application
Protection and monitoring of systems in which fault currents form, e.g. as a result of:
• Dust deposits or moisture,
• Porous cables and wires,
• Capacitive fault currents,
• Insulation faults.
Measuring current in the Energy Meter 750
Measurement range:
• Current measuring input I1...I3: via transformer ../5A or ../1A (0.001...7.5 A AC)
• Current measuring input I4: via residual transformer ../30mA (0.03...30 mA AC)
NOTE: Direct current cannot be monitored.
In no way does measuring in this way relieve the user from the obligation to carry out recurring in-
spections of permanently installed electrical systems in accordance with DIN VDE 0105-100.
