The analog input requires a signal which is isolated
from frame. Min. resistance to frame: 50 kΩ.

Value according to analog signal
If 4-20 mA or 20-4 mA is selected and the signal falls
below 2 mA, the pump will indicate a fault. This
situation occurs if the connection is interrupted, for
instance if the wire is damaged.

5.16 Capacity limitation
5.13 Timer
The pump is dosing the set quantity in batches at the
maximum capacity or the set maximum capacity, see
section Capacity limitation.
The time until the first dosing "NX" and the following
sequences "IN" can be set in minutes, hours and
days. The maximum time limit is 9 days, 23 hours and
59 minutes (9:23:59). The lowest acceptable value is
1 minute. The internal timer continues even if the
pump is stopped by means of the on/off button, empty
tank or stop signal.
During operation, "NX" will always count down from
"IN" to zero. In this way, the remaining time until the
next batch can always be read.
"IN" must be higher than the time required to perform
one batch. If "IN" is lower, the next batch will be
ignored.
In case of supply failure, the set quantity to be dosed,
the "IN" time and the remaining "NX" time are stored.
When the supply is reconnected, the pump will start
up with the "NX" time at the time of the supply failure.
In this way, the timer cycle will continue, but it has
been delayed by the duration of the supply failure.

Setting range:
DME 60: 6.25 ml/batch - 120 l/batch
DME 150: 15.6 ml/batch - 300 l/batch
DME 375: 39.1 ml/batch - 750 l/batch
DME 940: 97.9 ml/batch - 1880 l/batch
Only values corresponding to complete dosing
strokes (according to the calibration factor) can be
selected. The minimum setting depends on the
calibration factor. The minimum setting shown above
corresponds to the default calibration value.
