Installation

Pressure Connection

Installation Examples

Use a Ø7.5 mm drill for installing the pressure connection nipples into the duct.

User Interface – LED Indication

Green LED

Flashing (1s interval) = EE610 operates normally, the measured data is within the selected measuring range
One flash (2s) = Confirms adjustment or return to factory settings
Off = No power supply or electronics failure
Fast flashing (0.2 s interval) = Auto-zero is executed, first time 10 s after start/reset

Red LED

Flashing (1s interval) = The measured data is out of the selected range (overload or reversed pressure connection)
One flash (2s) = Indicates the failure of the attempt to adjust zero point or span point, or to return to factory adjustment

EE600 with RS485 Interface

The bus termination shall be realized with 120 Ω resistor (slide switch on board).

Electronics Board Layout

  1. Termination resistor 120 Ω slide switch: 1=ON, 0=OFF
  2. Status LED
  3. USB configuration adapter
  4. Display
  5. Supply and RS485 terminals
  6. Push buttons for span and zero point adjustment
  7. Address switch
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). Default address 43.
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 (43) or the address set via Software.
Example: Address set to 3 (0000 0011 binary).

Communication Settings

---|---|---
| Factory settings| Selectable values| Factory settings| Selectable values
Baud rate| As ordered per type number | 9600, 19200, 38400, 57600, 76800| As ordered per type number| 9600, 19200, 38400

BACnet Protocol

The EE600 PICS (Product Implementation Conformance Statement) is available on the website at www.epluse.com/ee600.
The recommended settings for multiple devices in a BACnet MS/TP network are 38400, 8, None, 1.
Address and Baud rate can be set via:

  1. PCS10, Product Configuration Software and the USB configuration adapter cable HA011066.
  2. BACnet protocol, see the PICS.
Modbus Protocol

The recommended settings for multiple devices in a Modbus RTU network are 9600, 8, even, 1.
Address, Baud rate, parity and stop bits can be set via:

  1. PCS10, Product Configuration Software and the USB configuration adapter cable HA011066.
  2. Modbus protocol in the register 60001 (0x00) and 60002 (0x01).
    See Application Note Modbus AN0103 (available on www.epluse.com/ee600).

The measured parameters are saved as a 32 bit floating point value and as 16 bit signed integer value, see the Modbus register map below.
