ABL METERS Installation And Configuration Manual page 27

NOTE
Explanation of the fallback value
If you are not sure which static maximum current the charging group should be limited to if the time limit (see be-
low) is exceeded, enter the value 0 A here: This will cause all charging operations to be interrupted in the event
of a fallback.
WARNING!
Setting the other controller parameters
If required, you can also set the other controller parameters on this page. However, if you are unsure what each
parameter does, you should leave the value at the default setting!
ƒ Minimum Value: Specify a minimum current for the system here. The recommendation is 0 A, although you
may also increase this value if you want a minimum current in the installation.
ƒ Time Limit: Set how long the communication between the energy meter and the controller / control unit
needs to be interrupted before the charging group is set to the Fallback Value here (see above).
ƒ Start Value: Set the starting current for the charging group until the measured values from the energy meter
are available here. It is recommended to set the Start Value and Fallback Value the same.
ƒ Reading frequency: Set the time interval for retrieving the meter value here. The value must be greater
than 3 seconds. The recommendation is 5 seconds
ƒ Buffer width: Set a safety buffer here to avoid frequent and short-term oscillation of the current above
the main terminal current limit. The recommendation is to set the buffer width to 10% of the main terminal
current limit.
ƒ Validation Count: Set the number of measurements until the current setting is readjusted here. The product
of the Validation Count and the Reading frequency (see above) results in the time until the current set-
ting is readjusted (for example: 5 * 5 seconds = 25 seconds).
However, if the maximum current is exceeded, the current setting immediately readjusts.
