INTERPRETATION OF ACOUSTIC SIGNALS
The control unit emits sounds which help you understand if the screwing has been carried out correctly or
not. When the torque is reached meeting all the parameters set, the control unit utters a 0.5 sec beep as
confirmation. In case of Program End, the unit will utter other two beeps. On the other hand, torque reached
under min time, during the Ramp time or under the Fast Speed (see error signals on the display) will cause
the control unit to utter three beep sounds.
I/O CONNECTIONS
EDU 2AE/TOP control unit series have connectors placed on the back panel. These connectors allow to
enable functions through inputs and to take signals through outputs. The inputs are activated by connecting
them to ground. A positive voltage must NEVER be brought to these inputs. Bringing 24V to the unit inputs
could damage the inputs themselves. As seen from the picture below, to enable the inputs it is recommended
to bring a clean contact by using a relay or a simple switch or button.
As for the outputs, they are all PNP type with active function. On each pin you will have 24V DC.
