Error Signals
An error or fault signal is indicated when the transducer detects a condition which effects its
fundamental operation. An error or fault condition will be indicated by a solid red LED. Any
error that occurs will latch the LED on and it will remain on until the transducer is reset. An
error condition will override a warning and normal mode LED sequence.
If the error persists across multiple power cycles, a fault may have developed with the
transducer and you will need to contact the factory.
Peak Input
The peak input is a control signal and has two main purposes. It controls what data gets
applied to the torque analog output and it can be used to reset the peaks.
The peak input is activated by grounding pin 8 of the Analog 15 Way ‘D’ Socket. The best way
to control the peak input is to use a toggle switch.
Analog Output
When activated any analog output channel configured as “Torque – Auto Assign” will switch
from being the current torque value to the highest measured torque value since reset, if the
analog output is not unipolar then the torque direction will be output.
Peak Reset
When the peak input is toggled, i.e. off-on-off or on-off-on, all internal peak values on both
analog and digital interfaces will be reset to defaults. A peak input toggle will also clear any
latched fault condition.
