Electrical Connection
WARNING
Incorrect installation, wiring or power supply may cause overheating and can therefore lead to personal injuries or damage to
property. For correct cabling of the device, always observe the presented wiring diagram for the product version used.
The manufacturer cannot be held responsible for personal injuries or damage to property as a result of incorrect handling,
installation, wiring, power supply or maintenance of the device.
Hardware
The bus termination shall be implemented with a 120 Ω resistor, switch on the electronics board.
NOTICE
Improper handling of the device may result in its damage.
▪
The power supply must be strong enough to ensure supply voltage within the specified range (see technical data) at any time
and at all devices in the bus. This is particularly relevant when using long and thin cables which can cause high voltage drop.
Please note that a single EE650 requires peak current of 150 mA.

1) The choice of measurement units (metric or non-metric) must be done according to the ordering guide, refer to EE650 datasheet.
Switching from metric to non-metric or vice versa by using the PCS10 is not possible.
2) Register number (decimal) starts from 1.
4) Examples: For scale 100, the reading of 2550 means a value of 25.5. For scale 50, the reading of 2550 means a value of 51.

Address setting via PCS10 Product Configuration Software
All DIP switches at position 0 → address has to be set via PCS10.
Modbus (slave device): factory setting 65 (permitted values: 1...247).
BACnet (master device): factory setting 65 (permitted values: 0...127).
Example: Address is set via configuration software = factory setting.
Address setting via DIP switch
Modbus (slave device): Setting the DIP switches to any other address than 0, overrules the
Modbus address set via PCS10 (permitted values: 1...247).
BACnet (master device): Setting the DIP switches to any other address than 0, overrules the
BACnet address set via configuration software.
BACnet Note: permitted values are 0...127. The 8th bit of the DIP switches is ignored
(ID 127 = 0111 111). To set address 0 via DIP switches, the 8th bit shall be set to 1
(ID 0 = 1000 0000). Example: Address set to 11 (= 0000 1011 binary).
