INTERPRETATION OF ACOUSTIC SIGNALS
The control unit emits sounds which help you understand if the fastening operation has been carried out
correctly or incorrectly. When the torque is reached meeting all the parameters set, the control unit utters a
0.5 sec "beep" as confirmation. On the other hand, torque reached under min time, during the Ramp time or
under the Brake time (see error signals on the display) will cause the control unit to utter two "beep" sounds.
I/O CONNECTIONS
On the back panel you'll find only one I/O connector with 10 pins.
INPUT:
PIN NAME
COM
Common pin. By closing the contact between pin 1 and any of the other pins ( 2, 3, 4, 5) to start the
1
0VDC function you need. This pin is connected to 0VDC and to the ground.
2 START
Remote start. Clockwise. Torque control.
3 REVERSE
Reverse remote start. Counterclockwise. No torque control
4 STOP
Stop motor. "STOP MOTOR ON" screen. Motor stops and starts again after the contact has opened.
NOT
5
Only used in special versions. See SPECIAL VERSIONS
USED
OUTPUT:
PIN NAME
Torque reached signal. Signal is 24VDC
6 TORQUE
Lever signal: when lever is pressed or when the start is remote. No signal during unscrewing cycle. It
7 LEVER
resets after their release. Signal is 24VDC
Error signal: it activates every time an error occurs.
8 ERROR
The error signal resets after 3 beep sounds.
Signal is 24VDC
Common pin for any output. Signals must be taken between pin 1 ( 0VDC common) and the other
9 COM0VDC
pins (6,7 and 8).

ATTENTION: Output signals are protected from an appropriate circuit. Overload of the available
signals (> 450 mA) or short circuit will result in the stop of the unit. To re-activate signals, it is
necessary to switch off the unit for 5-6 seconds, check connections and output loads then switch the
unit on.
