Pin 3-8 must be shorted to allow the Turbo-V 2000HT 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
INTERLOCK optically isolated from the internal circuit, this signal can be used
to delay the starting of the turbopump. requires a permanent closed contact
before starting the turbopump.
SYSTEM OVERRIDE optically isolated from the internal circuit, this signal is
used to stop the pump in emergency condition, requires a closed contact.
When the contact is closed, the turbopump and the interconnected devices are
stopped.
