8.1. Interface (fig. 47)
This built-in analog interface allows external pump control.
-
Control voltage 0 - 10 volts equals a rotational speed of 0 to max.
control voltage
0 - 0,9 V
1 V
10 V
Or control current 4 - 20 mAmps for rotational speed of 0 to max.
control current
0 - 4.9 mA
5 mA
20 mA
5 V TTL signal inverts sense of rotation (at standstill only !)
-
A 5 volts TTL signal turns item ON, next signal to follow turns item OFF. This function is
-
available all the time (in internal mode either).
For triggering sense of rotation and ON / OFF function, a 5 volts pin is available in the
-
interface connector, which allows potential-free switching.
The analog interface is recognized at a level of 0.2 volts or a 4 m Amps current;
-
Interface socket wiring (37):
Interface socket is located on the pump drive's rear panel; pin wiring:
-
Use IP 67 plug connectors only (6-pin 99-5121-15-06) Heidolph P/N 14-010-006-81 not to
-
void splash protection.
Make sure, plug connectors are installed properly.
