Connection
2.7 Connecting the Interface
A description of the interface for operating the TUR-
BOTRONIK with a computer can be ordered under the
description SB 05.207.
The parameters for the interface will be set at the DIP
switches.
At DIP switch 1 you can choose whether the analog out-
put voltage at the terminal strip REMOTE will rise pro-
portionnally to the motor current or the speed.
ON analog output = motor current LOAD.
OFF analog output = SPEED.
2.8 Connecting the Remote
Control Unit
For the signal assignments of the terminal strip REMO-
TE refer to fig. 12.
Switching examples see fig. 13.
Technical Data see section 1.3.
Relay statuses see table 4.
Note for Switching Example ON/OFF Switch
If instead of the ON-OFF switch a jumper is established
between Pin 4 and 20, the TURBOVAC will start up auto-
matically once the TURBOTRONIK is switched on.
Caution
The maximum permissible voltage at each
of the terminals is 25 Veff AC, 60 V DC ver-
sus protective conductor.
Inputs - Remote control active
REMOTE Disables the keys and activates the
remote control inputs
(continuous signal; High-active)
START pump Impulse or continuous signal;
High-active
STOP pump Impulse or continuous signal;
Low-active
HEATING Heating ON/OFF steady-state
signal; High = On, Low = Off
Speed (target value) analog signal
Due to safety reasons the STOP function (Low-active) is
dominant.
In order to start the TURBOTRONIK via the remote con-
trol:
the REMOTE-inputs must be activated
i.e. high-level between “+” and “-” terminal,
the STOP-inputs must be inactivated
i.e. high-level between “+” and “-” terminal,
the START-inputs must be activated
i.e. high-level between “+” and “-” terminal.
Outputs
Acceleration,
Normal operation,
Failure,
Current-/speed actual value,
The reference voltage is +15 V for speed potentiometer
and remote control inputs.
The reference voltage is protected by the fuse F7. Posi-
tion of the fuse se fig. 14. For changing the fuse open the
TURBOTRONIK as described in section 2.9.
