LED strip: These three LED strips can be used to display the load status of the switch device obtained by quickly checking REF542plus
The most relevant information. They are labeled as M1, M2, and M3 respectively. Each of them consists of 12 LED lights, 10 of which are green, and 2
One is red. Under normal circumstances, 10 green LED lights are specifically used to display 0% -100% of the measured rated value of the configuration. to
Yes, each LED light corresponds to 10% of the rated value. Two red LED lights display a 20% overload status. These LED strips
The displayed measurement values can be set using operating tools.
Indicator LED: 8 freely programmable three color LED lights are available for display. These LED lights are distributed on 4 pages. Therefore, overall
32 indicator options, programmable for corresponding protection, control, monitoring, and switch input related time and status.
LED lights can be assigned to specific conditions using operating tools.
Infrared (lrDa) interface: This is an infrared serial interface that can be used to connect REF542plus to a personal computer. Use in combination
Suitable cables and operating tools can be used for the following operations:
Download the configuration to the unit.
·Upload the current configuration from the unit.
·After a malfunction occurs, upload the fault recording data. Only after pre enabling fault recording with the operating tool, can it proceed
Perform this operation.
Upload other information (measurement values, switch input status, switch output status).
Do not make any changes to the configuration of REF542plus unless you are familiar with REF542plus and its operating tools.
Changing its configuration may result in malfunctions and loss of warranty eligibility.
function. When the device is in operation, the green LED is turned on. When there is no auxiliary power supply or the equipment is not running (FUPLA is not available)
When running, the LED will turn off.
Communication malfunction. The display of this LED is only meaningful when the REF542plus is equipped with a communication module. When a communication module is detected,
The LED turns green when turned on. If there is no or no communication module detected, the LED will display in red. Installed Modbus communication
When the communication error rate increases after the signal module, the LED turns orange. When the communication error rate causes poor communication, it turns red.
When no communication error occurs or the module status register (see Modbus Technical Reference) is reset, the LED turns back green
Color. When the communication module is not present, the LED remains off.
·Alarm: When the user-defined alarm is valid, the LED turns red. Several alarm bars can be defined and configured using operation tools
Item. Alarm conditions can include tripping of protective functions, loss of SFs in circuit breakers, and so on. When the LED is turned on, it cannot be turned off
Close the circuit breaker or download a new configuration. Firstly, the alarm must be confirmed.
Interlock error: LED usually displays green. If the user attempts to perform an operation that violates the interlocking conditions, the LED will temporarily change to
red For example, operating the isolation switch when the circuit breaker is in the closed position.
