Circuit Description The torque curve switch circuit allows the operator to select from up to three preprogrammed torque curves using a two- or three-position switch depending on which curve the original equipment manufacturer (OEM) has provided.
Component Location The location of the torque curve switch circuit varies with each OEM and equipment model. Refer to the OEM manual.
Shop Talk The switch should be monitored for proper operation in INSITE™. If the switch is changing state correctly on the service tool, then the problem does not lie in the switch circuit. The three-position switch has three states:
1) Position 1 – open 2) Position 2 – closed 3) Position 3 – 1500-ohm resistance.
The two-position switch has two states: 1) Position 1 – open 2) Position 2 – closed.
