Pin arrangement and remote plug functions
Pin Nr. Input open (low) Input closed (high) On + 24 V (pin 1)
1 +24 V
2 venting blocked (see Section 3.5.) venting release (see Section 3.5.)
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 activated.
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 4.10. ”Rotation Speed Setting Mode”)
8 Output (low) Output (high)
rotation speed set rotation speed switchpoint attained;
switchpoint not attained output can be loaded with 24 V/50 mA
9 Output (low) Output (high)
collective malfunction message; malfunction-free operations
output can be loaded with 24 V/50 mA

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 10 pole
screw connector plug (maximum cable cross section
0.14 - 1.5 mm2/connection).
Shielded cable should be used. Shielding has to be
connected with the TC casing on the plug side of the TC 600
by using cable clamps.
The inputs 2 - 6 are activated by connecting them to the + 24V
on pin 1 (active high) (please see Section 3.12. ”Connections
Diagram”).
Pin Arrangement 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
