8.2
(2.4.4.2) Frequency
Configure the power frequency of the IT system to be monitored.
8.2
(2.4.4.3) Trigger
The locating current pulse of the ISOMETER® is synchronised with the measurement techno-
logy in the EDS via the BMS bus. This allows a more reliable detection of the locating current
pulse in the event of disturbances. Disturbances can be caused e.g. by variable-speed drives,
rectifiers, actuators, noise filters, PLCs, or control electronics.
8.2
(2.4.4.4) Fault memory
Faults that only occur temporarily can be stored.
•50 Hz
•60 Hz
•400 Hz
•DC
Settings made to the menu points ‚System type‘ and ‚Frequncy‘ will only have
an effect on connected EDS460 and NOT on EDS44… devices.
•Com
Synchronisation via BMS bus. The EDS only searches for insulation faults if
the insulation fault location has been started. Less time is needed for the
insulation fault location than with the "auto" setting.
•auto
No synchronisation
(e.g. if there is no BMS bus).
The EDS continuously searches for insulation faults.
If the trigger mode is set to "auto", the use of a portable EDS must be enabled in
the menu (menu item = "on"), since the measurement method is correspondin-
gly adjusted via this menu item.
•on
After eliminating the cause of fault, alarm messages remain stored
until a reset is carried out. This function applies to alarm and device
fault messages.
•off
The EDS exits the alarm state as soon as the cause of fault is elimina-
ted.
