epluse EE610 Low Differential Pressure Sensor

Specifications

Model: EE610 – Low Differential Pressure Sensor
Power Supply: 15-35 V DC
Analogue Output: 0-10 V / 4-20 mA
Digital Output: RS485

Product Usage Instructions

Electrical Connection

Ensure correct cabling of the device by following the wiring diagram for the product version being used. The power supply should be within the range of 15-35 V DC to avoid overheating and potential hazards.

Installation
Properly connect the pressure to the sensor and ensure a secure installation to prevent any leaks or malfunctions.

User Interface – LED Indication
The LED indicators provide important information about the status of the sensor:

Green LED:
- Flashing (1 s interval): Normal operation within the measuring range.
- One flash (2 s): Adjustment confirmation or return to factory settings.
- Off: No power supply or electronics failure.
Red LED:
- Flashing (1 s interval): Measured data is out of the selected range.
- One flash (2 s): Failure indication during adjustment.

Communication Settings
The sensor can communicate via RS485 interface with configurable settings such as Baud rate, Data bits, Parity, Stop bits, and Modbus address. These settings can be adjusted using the PCS10 software. Default settings are provided but can be customized based on user requirements.

FAQ

Q: How can I change the communication settings of the EE610 sensor?
A: The communication settings can be changed using the PCS10 software for user-selectable values such as Baud rate, Data bits, Parity, Stop bits, and Modbus address. Ensure to follow the provided guidelines for proper configuration.
Q: What should I do if the LED indicators show a failure during adjustment?
A: If the LED indicators show a failure during adjustment, refer to the user manual for troubleshooting steps or contact customer support for assistance. It is important to address any issues promptly to ensure accurate sensor readings.

User Interface – LED Indication

Green LED| | | Red LED|
---|---|---|---|---
Flashing (1 s interval)| EE610 operates normally, the measured data is within the selected measuring range| | Flashing (1 s interval)| The measured data is out of the selected range (overload or reversed pressure connection)
One flash (2 s)| Confirms adjustment or return to factory settings| One flash (2 s)| Indicates the failure of the attempt to adjust zero point or span point, or to return to factory adjustment
Off| No power supply or electronics failure
Fast flashing (0.2 s interval)| Auto-zero is executed, first time 10 s after start / reset|

Address Setting

Address setting via Software
- All DIP switches at position 0 → address has to be set via Software (via PCS10 Product Configuration Software or via protocol BACnet / Modbus). Defa lt address 44.
- Example: Address is set via configuration software.
Address setting via Dip-Switch
- Setting the DIP switches to any other address than 0, overrules the default address (44) or the address set via Software.
- Example: Address set to 3 (0000 0011 binary).
