Task 2 Turn on hydraulic pressure
This task activates the hydraulic pressure.
Do not place any part of your body in the path of a moving actuator.
A crush zone exists between the actuator and any equipment in the path of
its movement. Immediate and unexpected actuator response is possible
when you apply hydraulic pressure to your system.
Stay clear of the actuators when applying hydraulic pressure.
1. Ensure that displacement control mode is selected.
Standalone FlexTest SE Controllers: Select Status > Control Mode >
Disp.
Automated Controllers: Check Control Mode on the Station Manager
Function Generator panel.
2. Ensure that the Span is set for 100%.
Standalone FlexTest SE Controllers: Select Status > Span
Automated Controllers: Check the Master Span setting on the Station
Controls panel
3. Check hydraulic and program interlock indicators.
Standalone FlexTest SE Controllers: If the Hydraulic Interlock or
Program Interlock indicator is lit on the front panel, determine the cause,
correct it, and then click Reset.
Automated Controllers: If the Interlock or Program indicator is lit on the
Station Controls panel, determine the cause, correct it, and then click Reset

If either interlock indicator lights again, you will need to determine the
cause of the interlock and correct it before proceeding.
