■ Interval batch control (see page 42 & 54)
To make an interval batch control, set a date and time interval and the flow volume. The IX discharges the pro
-
grammed flow volume at a set interval. In the diagram below, the interval is set to 1 hour.
*
The pump runs at the MAN speed. The control is triggered by either the external pulse signal or the push of the key.
Push the key to stop the control when it is triggered by the key.
Example of use: Water transfer for a sprinkler system
AUX function
The pump runs at the AUX speed while receiving the external signal via the AUX terminal. See page 51.
*
This function works only when the pump is running in either MAN or EXT mode (see page 40.). The pump returns to the
MAN or EXT mode once the AUX signal stops.
Priming function
The pump runs at the MAN speed (or the maximum stroke rate with default setting) while both the UP and
DOWN keys are pressed. Use this function for priming or degassing. Release both the keys to stop the pump.
See page 55 for detail.
* This function is available at any time except when the pump is in the MAN/EXT selection or menu selection (see page 40.).
