Pin 3-16 must be shorted to allow the Turbo-V 2000 ICE pump to start if no
NOTE
interlock contact is connected. If after starting the pump, the interlock contact
opens, it has no effect on the operation and the pump continues to turn.
The following figure shows a typical contact logic input connection
and the related simplified circuit of the controller.

DESCRIPTION
FAULT signal 24 V, 60 mA, optically isolated output (pin 23 positive pin 11
negative). The output Voltage will be present when a fault condition is
displayed on the front panel display, with exception of an overtemp condition.
Analog output Voltage of power drawn by the turbopump (pin 12 positive, pin
25 negative). 10 Vdc proportional to 1000 W.
Analog output voltage (0 - 10 V) of pump speed (pin 13 positive, pin 25
negative).
BRAKING signal 24 V, 60 mA, optically isolated output (pin 24 positive pin 23
negative). The output voltage will be present when the pump is in its
deceleration phase, with exception of an overtemp condition.
Open collector type contacts
