Siemens 400 V / 210...590 A operating instructions Toggle key, Key

01.2004Parameterization

Toggle key	Since the seven-segment display on the PMU has only four digits, the 3
(P key)	descriptive elements of a parameter, i.e.
	♦ parameter number,
	♦ parameter index (for an indexed parameter) and
	♦ parameter value
	cannot be displayed simultaneously. It is therefore necessary to switch
	between the 3 elements. The toggle key is provided for this purpose.
	After the desired level has been selected, the parameter number can
	be adjusted with the Raise or Lower key.

Using the toggle key, you can switch

•from the parameter number to the parameter index

•from the parameter index to the parameter value

•from the parameter value to the parameter number

If the parameter is not indexed, the toggle key switches directly from the parameter number to the parameter value.

NOTE	If you change the value of a parameter, the new value normally
	becomes operative immediately. However, in the case of confirmation
	parameters (identified by an asterisk " * " in the Parameter List), the
	new value does not take effect until you switch from the parameter
	value to the parameter number.
	Changes to parameter settings made via the PMU are always stored in
	the non-volatile EEPROM after confirmation by the toggle key.
