# Features
1. Forward, Reverse, and Ultimate Limit Override Buttons
2. Forward and Reverse Jog Buttons
3. OLED Status Display
4. Knob
5. Forward Safety Sensor, Reverse Safety Sensor, Valve Enable, and Power Indicator Lights
### Limit Switch Override Buttons
Ever hit a limit switch and grumbled about having to grab a screwdriver to adjust the switch during initial installation? Grumble no more, you can press the corresponding override button to temporarily disable the limit signal.
### Forward and Reverse Jog Buttons
Press and hold the FWD or REV jog button, then turn the speed knob, to manually move your hydraulic effect.
### OLED Status Display
A two-line display shows handy, at-a-glance info. It’s OLED which makes it easy to see backstage in the dark.
### Knob
When used with the jog buttons, turning the knob will adjust the speed from 0%-100%. The knob, when pressed, is also a button for network configuration.
### Status Indicator Lights
On the Stagehand Hydraulic, there are 4 LEDs to indicate the status of the controller. The 4 indicator lights display the following information
* FWD Safety Sensor Clear: A green light indicates that the forward safety sensors are not engaged. If a safety sensor is struck (e.g. bumper switches, pressure mats), the light will turn off and no further motion in the forward direction will be allowed.
* REV Safety Sensor Clear: A green light indicates that the reverse safety sensors are not engaged. If a safety sensor is struck, the light will turn on if no safety sensor (e.g. bumper switches, pressure mats) are engaged in the REV Safety control loop the light will turn off and no further motion in the reverse direction will be allowed.
* Valve Enable: A yellow light will turn on if the hydraulic valve is enabled
* Power: A green light will turn on if the Stagehand Hydraulic is receiving input power
### Persistent Position
Stagehands used to require a battery backup to maintain encoder position data through a power loss. However, we never loved this solution. Wouldn’t it be better if the Stagehand could remember the machine’s position without a battery? Yes, we thought so too. We developed a nifty feature in the Stagehand firmware that records the encoder position to flash memory and then reads that position back if it loses power. This bit of engineering removes the need for a battery backup inside the Stagehand Hydraulic.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.creativeconners.com/docs/stagehand/stagehand-hydraulic/features.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
