How the input check circuit
detects resolver chain breakage
When the dual safety valve relay is energized by the press
control to start the press, voltage will be produced in the input
check circuit. This signals DiPro that the press ram should begin
to move. If DiPro gets no signals from the resolver within a short
period of time (resolver not turning), it opens the emergency stop
circuit. A "loss of rotation" fault message is displayed on the
screen. The press could have started but the resolver belt or chain
broke or was way too loose so the resolver shaft did not move.
Other possible reasons for the fault could be low air pressure to
the clutch or a bad clutch.

5. Find the 115V-230V voltage selector switch. It is just below the power
connection to the left. If your AC power is 115V, check to see that "115V" is
displayed in the switch cavity. If your AC power is 230V, push the handle down.
You will see "230V" displayed.

6. Run power, stop circuit, and input check circuit wires through flexible liquid tight
conduit to the enclosure. The DiPro 1500 enclosure is rated NEMA 12 (protected
against dust and oil). You must use conduit of the same rating and make proper
connections to ensure NEMA 12 protection.
