Lifter Interface Signals
These signals can be directly connected to a Sensor™ PHC standard lifter using the supplied cable.
Lifter Interface Signals 9-Pin D Subconnector
Name Pin #s Signal Type
Lower limit switch * 6 - Switch to common Isolator input
Upper limit switch * 2 - Switch to common Isolator input
Torch breakaway switch 7 - Switch to common Isolator input
Torch tip touch sense 4, 5, 9 Attenuated filtered analog

Field common 3, 8 Field power common
* The PHC standard lifter does not include limit switches and the PHC detects the hard stop limits by
monitoring motor speed.
Lower Limit Switch
This signal is an output from the lifter and an input to the PHC. The lifter can activate this signal to indicate that
the lifter has reached the lower range of motion. The normally open/closed sense of this signal can be
changed through setup DIP switch #14. The use of a limit switch is optional.
Upper Limit Switch
This signal is an output from the lifter and an input to the PHC. The lifter can activate this signal to indicate that
the lifter has reached the upper range of motion. The normally open/closed sense of this signal can be
changed through setup DIP switch #14. The use of a limit switch is optional.
Breakaway Switch
This signal is an output from the lifter and an input to the PHC. The lifter can activate this signal to indicate that
the mechanical torch breakaway has tripped. The normally open/closed sense of this signal can be changed
through setup DIP switch #15. The use of a torch breakaway switch is optional.
