Voltage relay ZUBR D2: (hereinafter referred to as the device) designed to protect electrical equipment from critical mains voltage surges. Equipment sensitive to line voltage deviations: refrigerators, TVs, video and audio equipment, computers, etc.

IN THE BOX

Voltage relay ZUBR D2: 1 piece
Technical data sheet and installation and operation manual and warranty card: 1 piece
The packing box: 1 piece

CONNECTION SCHEMES

Supply voltage (100 – 420 V, 50 Hz) served on terminals 1 2, and phase (L) is connected to terminal location 1, and the neutral conductor (N) to terminal 2. If a circuit without a neutral bypass through D2 is used, the neutral wire can also be connected to terminal 4.

• Before the installation and operation of the device,
• PLEASE READ BY THE END OF THIS DOCUMENT.
• This will help to avoid possible danger, mistakes and misunderstandings.
• All settings are stored in NON-VOLATILE MEMORY

INSTALLATION

The appliance is intended for installation inside residences The risk of moisture or humidity in the installation site should be minimal.The ambient temperature during the installation should be within –5…+45 °С.

The appliance is installed in a special box, which allows to conduct the easy installation and operation. Cabinet should beequipped with standard mounting rail 35 mm width (DIN rail). The appliance takes in width of two standard module on 18 mm. The height of the appliance should be in the range 0,5…1,7 m from the floor.

For protection against short circuit and excess capacity in circuit load necessarily need to set in front of the appliance, the automatic circuit- breaker (QF). The automatic switch off is established in the open-phase fault wire, as shown at the schemes 1, 3. To protect person from electric shock leak is set safety shutdown device.

Terminals of the device designed for wire cross section 2 up to 16 mm². It is advisable to use a soft wire, which is tightened in the terminals with a screwdriver with a tip width of no more than 6 mm with a torque of 2.4 Nm. A screwdriver with a blade more than 6 mm wide can cause mechanical damage to the terminals. Doing so will void your warranty claim.

EXPLOITATION

The device will immediately begin to display the voltage on phase. If the voltage is normal, the voltage will be applied to the load after the set time and the green indicator will light up.

• Use the button to navigate through the menu.
• Use the and «–» buttons to change the parameters.
• To browse the abbreviation expansion of the menu item, use the «і» button. After pressing the button for the first time the parameter will flash, after pressing it for
  the second time the parameter will change. After 5 sec after pressing — return to the mains voltage display.

WHEN SETTING THE VOLTAGE limits use theprotected equipment technical documentation.

Setting trip limits (factory setting 242 V / 198 V)
To view the upper limit, press the«+» button, to view  the lower limit, press the  «–» button. Then use the «+» and «–»  buttons to change the limit as necessary.

Locking the controls

Hold down the «+» and «–» buttons for more than 6 sec until the message «Loc» («unLoc»)  appears on the screen

A tripping counter

Not discharged. To view hold the button «і» for 12 sec.

Delay in the load starting after a failure (control is described in table 1)
During a voltage jump before the countdown for 1,5 sec, an emergency situation will be displayed, then for 1,5 sec the voltage with a flashing dot to the right.

The countdown in seconds («t99.», start until the load is turned on.
If you set a delay longer than 100 sec, the screen will display the current voltage with a flashing dot to the right. If the remaining time is less than
99 sec, it will display the countdown in seconds.

Reset to factory settings
Hold the buttons «+» and «–» until «dEF» message appears on the screen. After release, reset to factory settings and reboot will take place, the alarm log is cleared.
Viewing of firmware version
Hold the button «і» for 6 sec. The manufacturer reserves the right to modify the firmware to enhance the device technical characteristics.

More about some functions via QR code
The link describes in more detail the functions of your device as listed in Table 1. Please note that your device only has the functions described in these instructions. Notes

• 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.
• You can use correction if voltage indications on the screen of the device and your reference device differ.
• Does not disable the protected equipment at safe voltage deviations in value and duration. See the link via QR code (page 6) for more details.
• It is necessary to fine-tune the response time of the protection to power failures. See the link via QR code for more details: the Pro mode is enabled: 154-176 V, the Pro mode off: 120-210 V.
• «tAr» — delay is counted from the moment of voltage recovery. «tAo» — delay is counted from the moment the relay is turned off and takes into account response time of the emergency in the total on-delay time.
• 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. See the link via QR code (page 6) for more details.
• It limits the number of repetitive limit trips if no more than 20 seconds have elapsed between the trip and the load turning on. To disable the function, select «oFF». See the link via QR code (page 6) for more details.
• At 0, 30 seconds after the last button press, the screen is completely off. During an emergency, the screen will be 100% lit.

Log for 100 accidents
The device stores in non-volatile memory the voltage values at which the load was interrupted or «oht» overheat triggering (see the link via QR code for more details).
To view: the alarms press «i». Log entries are displayed in order from the last to the oldest («n 0» is the last entry, «n99» is the oldest). Hold down «i» to browse through the log quickly. To browse up or down, use «+» «–».
The value of each crash is accompanied by a single flash of its number, where «n 0» —is the most recent and «n99» is the oldest

To reset the log, wait until the device returns to the mains voltage display. Then hold down the «i» button for 3 sec until «rSt» appears. After releasing the button, the log will
be cleared.

POSSIBLE PROBLEMS, CAUSES AND WAYS TO OVERCOME THEM

At turning on neither indicator nor screendo not shine

• Possible cause: There is no power supply voltage.
• It is necessary to: Ensure supply voltage presence. After turning on on the screennormal voltage level, but load is not turning on
• Possible cause: the current voltage in the network is close to the established limits and not stable.
• It is necessary to: check the values of the limits; increase their values so that the protected equipment is tolerated to them. In other cases, please, address to a service centre.

The load is disabled, «oht» flashes on the screen
The temperature inside the housing exceeded 80 °C and triggered protection against overheating. The screen shows «oht» 1 second.

Possible cause: inner overheating of the device to which can lead: bad contact in the terminals of the device, high ambient temperature, overwhelming power output or incorrectly selected cross-section of wires for connecting.

It is necessary to: check tension of power wires in the device terminals, make sure that the switching load does not exceed the permissible and that the cross section of the wires is selected correctly. Feature of protection against internal overheating — see the link via QR code (page 6) for more details.

The load is disabled, the screen displays «rEP»
Possible cause: the maximum number of consecutive trips for exceeding voltage limits has been exceeded.

It is necessary to: check the cause of the operation according to the alarm log. Make sure that the protection operation settings are correct (see Table 1 «rEP»).
If necessary, change the protection settings, if this does not conflict with the capabilities of the connected load. Unlock the relay by pressing any button.

Every 5 sec the screen displays «Ert »

Possible cause: open or short circuit of the internal overheating sensor. Control over inner overheating will not be done.
It is necessary to: Send the device to the Service Center. Otherwise, control over inner overheating will not be done.
