EXPLOITATION

3F will immediately begin to display the voltage in three phases. If the voltage is normal, the voltage will be applied to the load after the set time and the red indicator will light up.

Use the middle button to navigate through the menu (table ). Use the 1 «+ » « –»  and  buttons to change the parameters. After pressing the button for the first time the parameter will flash, after pressing it for the second time the parameter will change. In 5 sec after the button was pressed the indicator will return to displaying the system voltage.
All settings are stored. in NON-VOLATILE MEMORY When setting the voltage limits USE THE PROTECTED EQUIPMENT TECHNICAL DOCUMENTATION.
Setting trip limits ( factory setting V V 242 / 198 ) To view the upper limit, press the «+» button, lower — «–» . To change the limit as necessary use the and «+» «–» .

**Delay in the load starting after a failure( control is described in able t

1. ** During a short-time voltage jump before the countdown for 2 sec, an emergency situation will be displayed, then for 2 seconds the current and remaining time before the load is switched on. Screen during the delay countdown:

current phase voltage time to turn on the voltage in seconds current phase number

FOR PROTECTION OF REFRIGERATION
EQUIPMENt, where there is a compressor, it is recommended to set a delay of turning on load 120–180 sec. It will allow to increase the service life of the compressor .

Factory reset
Hold the three buttons at the same time until message appears. After releasing the buttons, the settings will be reset and the device will restart. «dEF»

Log for 100 accidents
The device stores in non-volatile memory the voltage values at which the load was interrupted. To enter the log, press the « » button. ≡ Log entries are displayed in order from the last to the oldest («n 0» is the last entry, «n99» is the oldest).
To move through the log and view previous alarms, use the » or «+ « »– buttons. In the first 2 seconds, the relay wil display the number and type of the alarm. In the next 2 econds, it will display the value.

Examples of alarms log entries:
Phase unbalance alarm. The imbalanced phases will blin.

To clear the log file, enter it by pressing the middle button once. Then hold the middle button for 3 seconds until the message appears «Err» . Keep holding the middle button until the message appears «Err rSt» . After releasing the button, the log file will be cleared. If the log file is empty, after pressing the middle button, the relay screen will display _ « » .

FUNCTION MENU| Press « »≡| Screen| Notes
---|---|---|---
View the log for 100 accidents| 1 time| | The log stores the cause of the load shedding. If several faults occur  simultaneously, the log entries will be made according to the following priority :
1. Three-phase fault or incorrect phase sequence.
2. Voltage imbalance.
3. Exceeding the upper or lower limit.
Delay in the load starting after a  failure (factory setting se  3 с, 3– 600 с a range of change se )| 2 times| | It is used to protect compressor equipment.
It is recommended to set a delay of turning on load 120–180 sec. It will allow to  increase the service life of the compressor.
Phase unbalance voltage (  20 , 10–80 factory setting V a range of  change V)| 3 times| | To disable, increase the unbalance value until the «oFF» message appears. If the  load is switched off due to a violation  of the phase unbalance voltage limit, the  v current phase voltages will alternate on the screen and  current phase unbalance  in volts  numbers of the phases with unbalance
The phase unbalance disconnection time (  1 с,  0–30 с) factory setting se a range of  hange  se|  times| | Permissible time of excessive voltage imbalance.
If the protection trips frequently, increase the time or the value of the phase- alteration voltage so that the protected equipment is tolerant.
Phase sequence (factory setting on  )  « »| 5 times (4 times, if  «Phase unbalance voltage» is off)| | If the phase sequence is violated, the current phase sequence and the voltage  across them will alternate on the screen. The phase sequence is always  determined relative to phase L1.
No-phase control (factory setting  on )  « »| 6 times (5 times, if  «Phase unbalance voltage» is off)| | No-phase control is only possible when the «Phase Unbalance Voltage» menu is  off. When the function is disabled, the device will not interrupt the load when  there is no voltage on the phase(s).
Professional model of the tripping  time when the voltage goes beyond the limits (factory  setting  «oFF» )| 7 times (6 times, if  «Phase unbalance voltage» is off)| | Does not disable the protected equipment at safe voltage deviations in value and  duration.
More details about the tripping time model when the voltage is out of range see Table 2.
Correction of voltage (  0 ,  ±20 ) factory setting V  a range of change V| 8 times (7 times, if  «Phase unbalance voltage» is off)| | You can use correction if voltage indications on the screen of the device and  your reference device differ.
To switch between the corrections for each phase, use the  « »≡
button, the fourth press brings you back to the function menu
number of the current phase
correction in volts
Hysteresis (factory setting 1 V, a range of change 0–5 V)| 9 times (8 times, if  «Phase unbalance voltage» is off)| | It is necessary to reduce the number of the device operations by the limit, when  the voltage in the network is close to the limit and is not stable.
Maximum number of protection  operations in sequence (factory  setting 3 operations, a range of  change 1–5)| 10 times (  times, if  «Phase unbalance 9 voltage» is off)| | Limits the number of repeated trips of the device by the limit, if no more than 20  seconds have elapsed between shutdown at  the limit and turn on the load.  To disable this function, select «oFF».
Enable/disable the screen in the  standby mode (factory setting  «on»)| 11 times (  times, if  «Phase unbalance voltage» is off) 10| | To disable this function, select «oFF». Turns off the screen after 30 seconds after  the last interaction with the device and in the absence of an emergency  situation. In the event of an emergency situation the screen will flash. To exit the  sleep mode, press one of the buttons once.
Type of voltage on-delay ( factory  setting  «tAr»)| 12 times (  times, if «Phase unbalance voltage» is off) 11| | «tAr» time after voltage recovery — delay is counted from the moment of  voltage recovery. «tAo» time after switching off — delay is counted from the  moment the relay is turned off. This type of delay takes into account response  time of the emergency in the total on-delay time.

Viewing of calculated linear stresses
Hold the button « »≡ for 3 sec. At the corresponding screens, the phase numbers will appear, between which linear voltages are calculated. When releasing the screens for 30  sec calculated linear voltages will be displayed with an accuracy of 2-3 V.

A tripping counter
(not discharged) Hold the button « »≡ for 15 sec

Viewing of firmware version
Hold the button « »≡ 2 for 1 sec. The manufacturer reserves the right to modify the firmware to enhance the device technical characteristics.
