Description
Product name:IR1575-435 Bender Programmable controller
Product details:
The currently measured insulation resistance is indicated on the LC display. In this way
any changes, for example when circuits are connected to the system, can be recognised
easily. When the value falls below the preset response values, the response delay “ton”
starts. Once the response delay “ton” has elapsed, the alarm relays “K1/K2” switch and the
alarm LEDs “AL1/AL2” light up. Two separately adjustable response values/alarm relays
allow a distinction to be made between prewarning and alarm. If the insulation resistance
exceeds the release value (response value plus hysteresis), the alarm relays return to their
initial position. Insulation faults are distinguished according to AC and DC faults (indication ±).
In the event of insulation faults on the plus or minus conductor, the corresponding +/- symbol is
activated on the display. If the fault memory is enabled, the alarm relays remain in the
alarm state until the reset button is pressed or until the supply voltage is switched off.
The device function can be tested using the test button. The parameterisation of the device
can be carried out via the LC display or the function keys integrated in the front plate.
The AC/DC sensitive residual current monitor RCMA420 is designed for monitoring earthed
power supply systems (TN and TT systems) where smooth DC fault currents or residual
currents continuously greater than zero may occur. These are in particular loads containing
six-pulse rectifiers or one way rectifiers with smoothing, such as converters, battery chargers,
construction site equipment with frequency-controlled drives. Currents in single conductors
can be monitored too.
The prewarning stage (50…100 % of the set response value IΔn2) allow to distinguish between
prewarning and alarm. Since the values are measured with measuring current transformers,
the device is nearly independent of the load current and the nominal voltage of the system.
