3 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
5 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
5 reset:
by supplying a pulse (T < 2s) with an amplitude of 24V a malfunction
acknowledgement can be processed
6 standby off standby on:
pump is accelerated to 66% of its nominal rotation speed
7 rotation speed setting mode off the rotation speed can be changed by feeding a PWM signal to this pin or
via Serial Interface RS 485 (see Section 4.7. ”Rotation Speed Setting Mode”)

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 3.12. ”Connection Diagram”).
Pin occupancy and remote plug functions
(please see following table)
When connecting supply voltage, the turbopump
is started.
