The new addresses will be added in front of the last value. The
remaining linearisation points should be entered in the new
addresses, independently from their actual sequence.
The added values will again be sorted upwards
within the existing linearisation points before
being saved.

If two pumps are controlled using the process transmitter, the alternating pump control
enables an even loading of the pumps. If a switch point is reached the pump with the
shortest running time is switched on. If both pumps are operational and a switch off point is
reached then the pump with the longest running time is switched off. The running times are
calculated internally. They are always reset to zero when the alternating pump control is
activated/deactivated or there is a power failure. The alternating pump control should only
be used when both relays are set to
MAX-
or
MIN-
function.
