7 LEVER Lever start up signal when the lever is pressed or a "START" signal is
transmitted. No signal during the untightening.
24 V-20 mA, max 0.5 W
8 ERROR Error signal is actuated when
- The torque is reached during the "slow start" phase
- The torque is reached during the "approach speed" phase
- The selected tightening time has elapsed without having reached the
