Not Used
External Print / Reset Input
Pins 1 & 2 are intended for use as an EXTERNAL PRINT / RESET:-
The switch must remain active for at least 200 mS. Screened cable is recommended.
Limit Outputs
Pins 3, 4, 5, 6, 7 & 8 are buffered logic outputs intended for Go/No Go control of external equipment.
The limit outputs are referenced to Pin 9 (Digital 0 V).
All limit outputs are active HIGH and are updated every 10 mS
The limit outputs change exactly with increasing torque, and at 0.5% of transducer capacity below the limit
with decreasing torque. This eliminates the logic lines oscillating.
The Limit output current is, High = -0.8 mA, Low = 16 mA (not for direct control of relays).
Tool Stop Output
Tool Stop is used to provide a stop signal for an external pneumatic, hydraulic or electric tool. When the
measured torque goes above the Tool Stop value (set in the Target Setup) this pin goes HIGH (5 V) with
reference to pin 9.
