The meanings of the items are as follows:
Permanent storage: C150-0000-STD new parameters will be stored in the device memory. They will be used immediately and every time
Valid at startup.
Temporary saving: new parameters are used immediately, but they cannot be saved in the device memory. At next startup
The previous parameters will be used.
Discard Changes: Discards the use of new parameters. No effect on the device.
When storing parameters, do not turn off the power of the host unit, or the entire device configuration may be damaged
In this case, you may need to download new configurations.

Protection function.
Use the up and down buttons to edit the time, then press Enter to confirm. You must complete the entry
Whole date and time: year, month, day, hour, minute, second.
Unit connected with the master clock: if the unit is connected with the master clock (especially when the signal is obtained through GPS
Clock), only the year can be set. The remaining date and time parts can be obtained from the master clock.
Unit connected to SCADA system: C150-0000-STD Generally, SCADA will change the date and time according to the service agreement used
Send to unit. When the protocols used are different, there are also some differences. IEC 60870-5-
103 Protocol: The IEC 60870-5-103 module controls the time. Time and date cannot be set from HMI.
LON LAG 1.4 protocol: the LON module controls the time. Time and date cannot be set from HMI. SPA
Bus and Modbus protocol: Generally, SCADA sets the date and time; However, it can still be set from HMI
Time and date.
In the debugging and testing mode, the user can access all switching and analog inputs of REF 542plus
Output. This mode is independent of the REF 542plus application. This mode of operation is designed to enable cabling
Verification is easier.
You need a super user key to enter this mode.
After entering this mode, the operation of protection function and control function will stop. Application software
No longer running, but not deleted from the device’s permanent memory. When the switchgear is off
When the power is on and in a safe state, enter the commissioning test mode.
To switch to this mode, the following operations must be performed in sequence.
*Close the REF 542plus host unit.
*Place the super user key in the electronic key sensor and keep connected.
*Open the host unit.
When the main unit starts, it will detect the electronic key and enter the debugging mode. In the startup status bar
Debug Test is displayed on the. After you see the text, you can remove the electronic key from the electronic key sensor
Out.
This mode allows to directly drive the switching output of the host unit. If these outputs match one
The secondary equipment can be operated when it is connected. The interlock function is disabled. Enter this mode
Before, put the switchgear in safe conditions.
