Rs 232 Interface - Heidolph PD 5001 Manual De Instrucciones

IEI
TTL-level 0 V = CW rotation, TTL-level 5 V = CCW rotation.
-
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; This mode is
-
confirmed by "EA" in the display. As long as the pump drive is controlled via the analog
interface, Start / Stop-key will be the only active key on the item.
Wiring of the interface connector (37):

-
not to void splash water protection.
Installation of plug connectors is limited to skilled personnel.

9.4.2. RS 232 interface (fig. 50)
The RS 232 interface allows pump control from a PC via parallel interface.
-
The RS 232 interface connector is installed in the rear panel of the pump drive. Wiring:
-
Use IP 67 plug connectors only (Binder 8-pin 99-5171-15-08), Heidolph P/N 14-010-006-82,
-
not to void splash water protection.
Installation of plug connectors is limited to skilled personnel.
-
Interface parameters: 9600 Baud, no parity, 8 bit, 1 stop bit.
As long as the RS 232 interface is active, all of the pump's control elements and displays will
-
remain active.
