Firmware Updater
This software is to update the firmware version of the PCR-LE Series.
Ver.
5.07
Last update
2020/11/4
Configuration
- Applied Products : PCR-LE Series — All models (*PCR-LE2 excluded)
- Applied Firmware Version : ver2.00 or later
- Caution: This update file can not used on firmware ver1.99 or earlier. PCR-LE series with firmware ver 1.99 or earlier requires hardware alteration. Contact your kikusui agent or distributor for details.
Notes
- Confirm the firmware version of the PCR-LE.
*You can confirm the firmware version by the CONFIG (SHIFT + OPR MODE) > MODEL ID (F5). - If any data is stored in the internal memory, save the data to the USB memory before updating the firmware version.
- The USB memory (up to 16GB) that recognizes the PCR-LE is required for the firmware update
*To confirm the applicable USB memory : Insert the USB memory to the USB port of the PCR-LE, then check for the display. If the “USB Memory Found” shows on the display, the USB memory can be used for the firmware update. If the USB can not be recognized by the PCR-LE, nothing will be displayed. - In a PCR-LE system that uses options such as the three-phase output driver, the firmware of all the PCR-LE units that make up the system must be the same.
- In case of failure for the installation of firmware version update, please contact your local distributor.

PCR-LE firmware
Improvement
The protection function when the output voltage range is L range and Vcc is FIXed has been improved.
VER 5.06
2020-3-25
PCR-LE firmware
Resolved issues
When a protection function was activated by the detection of outage, processing to invalidate the output control from SCPI command has been added.
VER 5.05
2020-1-28
PCR-LE firmware
Resolved issues
When the SD021-PCR-LE reconnects communication with the PCR-LE, the problem that setting frequency became the input frequency (50Hz or 60Hz) has been corrected.
VER 5.03
2018-11-22
PCR-LE firmware
Resolved issues
When the SD021-PCR-LE reconnects communication with the PCR-LE, the problem that setting frequency became the input frequency (50Hz or 60Hz) has been corrected.
VER 5.02
2017-10-10
PCR-LE firmware
Resolved issues
The sudden phase change feature of the sequence function has been corrected.
VER 5.01
2017-9-08
PCR-LE firmware
New Feature
The single-phase three-wire/three-phase system (option) feature has been improved. The master-slave parallel operation (option) has been improved. Firmware version 5.xx is not compatible with version 4.xx or earlier. As such, a firmware version check function that runs when a multi-phase operation system or parallel operation system is turned on has been added. If the PCR-LE system contains a mixture of version 5.xx and version 4.xx or earlier versions, “TRBL-22 VERSION ERROR” will occur when the power is turned on.
New Feature
An aperture time setting function has been added. * In conjunction with this addition, the following functions have been changed or deleted. - The measurement update interval of measured values has been changed to aperture time (except line voltage measurements and harmonic current analysis data). - The measurement averaging function has been deleted. - The estimated minimum frequency function has been deleted (a function that was available when an analog signal interface option (EX05-PCR-LE) was installed).
Updated
The soft sensing correction range has been changed from +10% to ±10%.
Updated
Frequencies less than 40 Hz have been excluded from the Soft sensing operation correction range.
Improvement
A function that displays the soft sensing control status on the front panel has been added.
Improvement
The protection function processing that takes place when a sensing wire connection error is detected has been changed. When the protection function is activated, “ALM-22 SENSING FAILURE” will occur. To clear the sensing wire connection error, use alarm clear. * However, depending on the hardware version, the previous error (TRBL-22 SENSING FUSH TRIP) may occur. In this case, the method to clear the sensing wire connection error is the same as before (turn off the power switch and then back on).
VER 4.53

PCR-LE firmware
Resolved issues
When a sequence is ended in AC+DC mode, the problem of the voltage not being set to the AC voltage specified in the last step due to the peak voltage limit when the preset DC voltage before starting the sequence + the AC voltage waveform’s peak value set in the last step falls outside the -431 V to 431 V range (H range) or -215.5 V to 215.5 V range (L range) has been fixed.

Resolved issues
When phase voltage was specified in single-phase three-wire DC mode, conversion to line voltage could not be carried out. This has been corrected.
Resolved issues
If the output was turned on immediately after a sequence was stopped with the OUTPUT key, the PCR-LE/LE2 was generating the voltage specified before the sequence execution. This has been corrected so that PCR-LE/LE2 generates the voltage at the end of the sequence.

If the internal VCC voltage was fixed, there were cases where the output voltages could not be set at once. This has been corrected.
Resolved issues
A problem that occurred when an analog signal interface option (EX05-PCR-LE) was installed in a single-phase three-wire/three-phase system (option) has been corrected. Signal source status display, EXT.OPT menu operation, and EXT.SIG menu display have been corrected.
