3.10. 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 Section 3.12. Connections
Diagram).
Pin occupancy and remote plug functions
(please see following table).
When connecting supply voltage, the turbopump
is started.
On delivery:
Pin 1, Pin 2, Pin 3 and Pin 4 are bridged in the
mating plug
.

motor, turbopump off
motor, turbopump on:
the turbopump is driven, current flows through the motor coils
4
pumping station off
pumping station on:
the turbopump is driven, backing pump is started via the relay box

heating off
heating on:
the heating is switched on once the rotation speed switchpoint is attained and off
when the rotation speed switchpoint is unattained
optional: sealing gas valve off1)
optional: sealing gas valve on1)

reset:
by supplying a pulse (T < 2s) with an amplitude of 24V a malfunction
acknowledgement can be processed

standby off
standby on:
pump is accelerated to 66% of its nominal rotation speed
