# ๐ฆ Status LEDs Indications
| Action | Description | LED |
|---|---|---|
| Power on | The device will turn on as soon as the required input voltage is supplied to the Dryer 2.1 and perform a startup self-check. | Red, yellow & green blink thrice |
| Stopped | The machine is not drying hydrogen, waiting for action. | Green off |
| Stand-by (Max pressure state) | The device is waiting for inlet pressure and will resume hydrogen drying automatically when the restart input pressure setpoint is reached. | Green blinking |
| Button press | When the start-stop button is pressed. | Red, yellow & green blink once |
| Factory Settings Reset | Simultaneously pressing the start-stop button and power up the device will activate Factory Settings Reset. | Running fire (each LED blinks after another) |

# Logic States
While operating the Dryer can be in the various logic states. CODE field is a numeric representation of the state available on the EL2.1 Modbus Interface. NAME field is a string representation of the state displayed in the Enapter Cloud and in the Enapter Web GUI interface. DESCRIPTION is the human-readable description of the state.
| CODE | NAME | DESCRIPTION |

| 263 | WAITING FOR PRESSURE | The dryer is waiting for a sufficient amount of inlet pressure |
| 259 | STOPPED BY USER | The dryer is not drying hydrogen because it has been stopped by the user. It is waiting for the next command desired by the user |
| 260 | STARTING | The dryer is starting up and checking which state to be in next |
| 262 | STANDBY | The dryer is waiting for the output pressure to decrease below the allowable threshold value |
| 265 | IDLE | The dryer is automatically stopped by DCN/IDCN, will be automatically started when at least 1 EL2.1 will become steady |
| 513 | DRYING 0 | Block 0 is drying the hydrogen, while block 1 is being heated and regenerated |
| 514 | COOLING 0 | Block 0 is drying the hydrogen, while block 1 is being cooled down after its regeneration |
| 515 | SWITCHING 0 | Block 0 is drying the hydrogen while slowly pressurizing block 1, to prepare block 1 for the next drying cycle |
| 516 | PRESSURIZING 0 | Both blocks dry the hydrogen to smoothly transition into the drying cycle of block 1 |
| 517 | FINALIZING 0 | Block 1 dries the hydrogen and block 0 prepares to be regenerated |
| 769 | DRYING 1 | Block 1 is drying the hydrogen, while block 0 is being heated and regenerated |
| 770 | COOLING 1 | Block 1 is drying the hydrogen, while block 0 is being cooled down after its regeneration |

# โ๏ธ Factory Settings Reset
Factory Settings Reset (Hard Reset) allows to reset device to factory settings.
To enable Factory Settings Reset:
- Turn off the device.
- Press and hold the
Start/Stopbutton and turn on the device. - Hold the button. LEDs start blinking one after another.
- Release the button. All LEDs will blink once.
- Factory Settings Reset started. Device will be automatically rebooted. All LEDs blink trice.
If the Start/Stop button have not been released Dryer will be in Stand-by.
# ๐ Remote Monitoring and Control
# Introduction
Dryer 2.1 comes with pre-installed UCM (Universal Communication Module) that allows users to monitor the device. Over-the-air updates ensure that the latest protocols and security fixes are supported.
Pre-installed UCM connects to the Enapter Gateway and send performance and error data to the Enapter Cloud. The data is stored in a time series database which displays it real-time on customizable dashboards.
Enapterโs mobile application ensures quick and easy installation of any energy system. Users can manage the dryer via the mobile app and will receive push notifications to warn of energy system issues.
# Network Requirements
# WI-Fi Requirements
802.11a/b/g/n (2.4 GHz only)
802.12 WEP, WPA, WPA2 Personal (Pre-shared key)
Wi-Fi client isolation must be disabled
Note
No captive portal or WPA2 Enterprise supported.
General Wi-Fi Note
The Enapter Cloud connection based on wireless communication and therefore the functionality can be affected with distance in between devices, obstructions between the devices and interference. Communication module inside the dryer works in station mode and utilizes Wi-Fi channel set in your infrastructure Wi-Fi router for used SSID. You are responsible to select the correct channel according to the local radio regulations.
# Connecting your Dryer 2.1 to Wi-Fi
To connect the dryer to wireless networks, follow the steps in the iOS or Android Mobile Application guides below. Please note, the QR-code or preinstalled UCM's ID and PIN are required when connecting to Wi-Fi as well as credentials for the 2,4 GHz Wi-Fi network.
