EN 60204 “Safety of machines” provides increased
operational safety by the monitoring of the control voltage circuit for
earth-fault using an insulation monitor. This is the main application
for the EMR4-R. There are similar requirements in medically used areas.
An earth-fault is signalled via a changeover contact so that a fault can
be cleared without expensive down time.
The device has a selectable fault memory so that the fault must be
acknowledged after it´s removal. By the use of a Test button the device
can be checked for correct operation at any time.

| AC or DC control voltage There is a device for
AC and also DC. Therefore the total control voltage range is covered.
The DC device has a multi-voltage source. Therefore AC as well as DC is
possible. |
