Controllers: EMP401-1 controller
Question 7: I have followed the instructions and connections set-up for my EMP401-1 controller, however when I am at the Hyperterminal window, I notice that the E-STOP input is active and am unable to run my sequence programme. What could be the issue?

Answer : For the EMP400 series controller, the E-STOP input is normally closed. Hence, you will need to manually wire pin 2 (E-STOP input) of CN1 to GND. This would reverse the logic for the E-STOP input. (Refer to page 15 of the operating manual for more information *HP-19036-3)
