3.12. Connecting The Remote Control
Unit
Remote control options for various functions are provided
with the connection "REMOTE" on the TC 600 via the 15-pole
D-Sub-Connector. Shielded cable must be used. Shielding is
on the plug side of the TC 600 connected to the TC casing.
The inputs 2-6 are activated by connecting them to the + 24 V
on pin 1 (active high) (please see 3.12. ”Connection
Diagram”).
Pin occupancy and remote plug functions
(please see following table)
Pin arrangement and function of the
remote plug functions
1) The option must be set via the Serial Interface RS 485
(see Operating Instructions PM 0547 BN, Pumping Operating with DCU)
2) The following technical data is applicable for the contacts:
Umax = 50 VDC
Imax = 1 A
