WEG SRW 01 Manual Del Usuario

Document: 10000116251 / 02
This ADDENDUM contains the modifications implemented for the V5.0X firmware, which must be used in
conjunction with the SRW 01 V4.0X User Manual.
The firmware version 5.0X of the SRW 01 Smart Relay has some operating differences from the previous version
4.0X. The first involves two new parameters to indicate the firmware version of the Current Measurement Unit
(UMC) or Current/Voltage Measurement Unit (UMCT) and the Expansion Digital Unit (EDU). The second deals with
a parameter to enable the use of the Expansion Digital Unit (EDU) and the third relates to the parameter to set the
Digital Output Functions (O1 to O8). The modifications are described below:
1. QUICK REFERENCE OF THE PARAMETERS
Parameter Description
P026 Firmware Version
(UMC/UMCT)
P027 Firmware Version (EDU)
P294 Expansion Digital Unit (EDU)
P277 to Digital Output Function O1 to
P284 O8
2. EXPANSION DIGITAL UNIT (EDU) CONNECTION
The Expansion Digital Unit (EDU) offers the option of increasing the number of digital inputs and outputs at the
Control Unit (UC). It has 6 digital inputs and 4 digital outputs. It is possible to use only one Expansion Digital Unit
(EDU) with each Control Unit, totalizing 10 inputs and 8 outputs. The Expansion Digital Unit (EDU) digital inputs
and outputs can be used to transfer any information to the system, to signalize the status of an external device, to
indicate error/trip, alarm or fault in the system etc.
The verification of the presence (connection) of the Expansion Digital Unit (EDU) is only performed if parameter
P294 is set to "1", indicating the use of the EDU. If the Expansion Digital Unit (EDU) is present and the
communication between both has been established, the Expansion Digital Unit (EDU) signalizes it through the Status
LED in solid green.
If the Expansion Digital Unit is connected without the proper setting of parameter P294 or if the communication with
the Expansion Digital Unit (EDU) is not established, the Expansion Digital Unit (EDU) will signal error by means of its
solid red STATUS LED. For details about the use of the LEDs of the Expansion Digital Unit (EDU), refer to item 7 of
the user manual.
Once the communication between the Control Unit (UC) and the Expansion Digital Unit (EDU) has been established,
if an interruption in the communication between the devices occurs, the action programmed by the user in the
parameter P312 will take place.
NOTE!
For firmware versions of the Control Unit (UC) below V5.00, the verification of presence
(connection) of the Expansion Digital Unit (EDU) was performed during the initialization of the
Control Unit (UC).
