General Notes on Startup
DANGER
Risk of electric shock if the protective earth conductor is not connected!
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the E-625 in the case of malfunction or failure of the system. If there are touch
voltages, touching the E-625 can result in serious injury or death from electric shock.
Connect the E-625 to a protective earth conductor (p. 15) before starting.
Do
not
remove the protective earth conductor during operation.
If the protective earth conductor has to be removed temporarily (e.g., in the case of
modifications), reconnect the E-625 to the protective earth conductor before restarting.
NOTICE
Damage of the positioner from oscillations!
Oscillation of the positioner is indicated by humming and this is caused by incorrect adjustment
of the notch filter and/or the P-I controller.
At the first startup, run a system test and, if necessary, correct the notch filter frequency
and the P-I controller settings in the E-625.
If oscillations occur during closed-loop operation, switch the servo mode off immediately.
If oscillations occur during open-loop operation, stop the positioner immediately.
