➜ TTL level 0 V = clockwise rotation, TTL level 5 V = counter-
clockwise rotation.
➜ TTL-pulse 5 V switches the rotation on and off again at the next
pulse. This function is always activated.
➜ For controlling the [direction of rotation] and [rotation start/
stop] functions, a voltage of 5 V is also available at the
interface socket in order to be able to switch with potential-free
contacts.
➜ The analogue interface is detected at a voltage of 0.2 V or a
current of 4 mA;
➜ Hei-FLOW Ultimate: When the interface is detected, the display
shows
[EA]
. As long as the pump drive is controlled via the
analogue interface, the display and all buttons except [Start/
Stop] are inactive.
