Hypertherm ArcGlide Torch Height Control - Operator tests

ArcGlide THC Instruction Manual 4-15
MAINTENANCE
The IHS test checks that the IHS process operates correctly. Perform this test when
lifter parameter values need to be adjusted or verified.
To test IHS:
• On the front of the HMI, press the IHS Test button. Each successive press of the
button moves the torch between the transfer and retract heights.
• On a Hypertherm CNC, the Test IHS soft key on the Process screen performs the
same function.
Operator tests
The operator can perform several tests to test lifter mechanics and initial height sense
(IHS).
• To test lifter friction, press the UP arrow button on the front of the control module
when the system turns ON.
• To test the up and down cycling of the lifter, press the DOWN arrow button on the
front of the control module when the system turns ON.
