2 Parameters
2.2 List of parameters
Description: Displays the power unit fan operating hours of the internal fan in the power unit.
The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has been replaced).
Dependency: Refer to: A30042
Note: For liquid-cooled chassis power units, the operating hours of the inner fan are displayed in p0251 and not in p0254.
Description: Sets the monitoring time for internal monitoring of the contactor feedback contacts.
For a value 0.0 or negative values, the particular monitoring is deactivated.
For index 0 ... 3:
Is used to monitor the delay time between the control and feedback signals of the particular contactor.
For index 4 ... 7:
Is used for simultaneity monitoring for a parallel connection. After a contactor has been opened or closed, this checks
whether, after the monitoring time has expired, all contactors of the parallel connection have assumed the same
state.
For index 2, 3:
The value -1.0 means that the particular opening time is taken from Index 0 or 1.
Index: [0] = Precharging contactor closing time
[1] = Bypass contactor closing time
[2] = Precharging contactor opening time
[3] = Bypass contactor opening time
[4] = Simultaneity precharging contactor closing time
[5] = Simultaneity bypass contactor closing time
[6] = Simultaneity precharging contactor opening time
[7] = Simultaneity bypass contactor opening time
Dependency: Refer to: r0256
Refer to: F05118, F05119, F30060, F30061
Notice: For index 4 ... 7:
The simultaneity monitoring is only activate after parameter save and POWER ON.
Note: - this parameter is only effective for chassis power units with 3 AC line connection and line contactors.
- the simultaneity monitoring can only be activated for a parallel connection.
- the feedback signal input of an open bypass contactor must be displayed in r0256 = 0.
- the feedback signal input of an open precharging contactor must be displayed in r0256 = 1.
- Determining practical monitoring times can be supported by a tracing r0256.
For power unit firmware version less than 4.6, the following applies:
There are no separate monitoring times for the delay time between opening and closing. In this case, the maximum
of the opening time and closing time is effective.
