ELTEX POWER CHARGER PC - High Voltage Release Control

BA-en-3041-2008_PC 41
4.3 Releasing the high voltage
The release of the high voltage requires two steps:
• Hardware release, see Chapter. 3.10
• Software release as described below
Software release options
• Automatic
The software is released automatically once the generator has powered
up.
• Analog setpoint
The software is released when the minimum voltage / current is excee-
ded; the release is canceled when the voltage / current drops below this
minimum value.
• Integrated control
The release is enabled / disabled directly via a button (ON/OFF) of the
integrated control elements.
Operating the generators with the ECC visualization system, a release
for the generator set on the ECC has priority. A deactivation at the
generator is not possible if the release has been set on the visualization
system ECC at the same time. The generator must be deactivated via
the ECC visualization system.
• CANopen®
The release can be enabled or disabled with the command transmitted
by the CANopen® bus.
• Ethernet based field bus
The release can be controlled via the Ethernet-based field bus (e.g.
ModbusTCP).
Caution!
Please note that for variants with active discharging and corresponding
parameterization of the discharge mode as “active”, the hardware release
for discharging must always precede the release for charging.
