“Protection 15A” is displayed on the status bar (it
happens when current on mosfets of bridge H is > 15
A for at least 500 ms).
- Reduce cycle rate and check settings.
- Avoid motor stalling.
- Unscrewing too heavy.

“OUTPUT DISABLED” is displayed on the status
bar. It is on the protection of the output signals
exceeding the maximum load (400mA).

SERIAL PORT:
EDU 2AE/HPRO/TA control unit is supplied with a serial 9 pin male connector. In this way you can print the
results of each screwing. The transmission characteristics are the following:
9600 (bits per second), 8 (data bits), n (no parity), 1 (bits stop 1).
Connection pin: PIN 2 = TX, PIN 5 = GND
The print string is the following:
Result = screw evaluation: correct or incorrect.
OK = the torque has been correctly reached, all the selected parameters are satisfied and the control
unit will give out a beep sound of 0.5 sec.
NOK = the torque has been reached during the ramp time or the fast speed (see error table). In this
case, the unit will give out 2 beep sounds and the red led will light up.
Screwdriver model = model of selected screwdriver.
% Torque = percentage of the set torque level.
S: Speed = speed value.
ST: Screwing time = it indicates the time of the screwing.
Screws Count = number of screws screwed/number of total screws of the sequence/ program.
T: Torque = torque value.
A: Angle = angle value.
Notice = in case of program end, it prints “Program End” or it indicates the type of error (see paragraph:
trouble shooting).
