ZUBR D2-32 Overvoltage Protection For Professional Instruction Manual

ZUBR D2-32 Overvoltage Protection For Professionals

Technical data sheet, installation and operation manual

Voltage monitoring relay ZUBR D2 (hereinafter referred to as the device) designed to protect electrical equipment from high and low voltage and from zero break. In case of voltage deviations, ZUBR D2 turns off the load, and in case of normalization it turns it back on. Equipment that is easily affected to line voltage deviations: refrigerators, TVs, video and audio equipment, computers, etc. All settings are stored in non-volatile memory.

INSTALLATION

Important. Before the installation and operation of the device, please read this document to the end. This will help to avoid possible danger, mistakes and misunderstandings.

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 °C.

The appliance is installed in a special box, which allows to conduct an easy installation and operation. Cabinet should be equipped with standard mounting rail 35 mm width (DIN rail). The appliance takes of two standard module on 18 mm in width. The height of the appliance should be in the range 0,5 … 1,7 m from the floor.
It’s important to set the automatic circuit-breaker (QF) in front of the appliance in order to protect against short circuit and excess capacity in circuit load. The automatic switch off is established in the open-phase fault wire, as it is shown at the Scheme 1. Safety shutdown device is set to protect a person from electric shock leak.
Terminals of the device are designed for wire cross section 2 up to 16 mm. 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 N•m. A screwdriver with a blade more than 6 mm wide can cause mechanical damage to the terminals. Doing so will void your warranty claim.

TECHNICAL DATA

CONNECTION SCHEMES

The power supply voltage (100-420 V, 50 Hz) is applied to terminals 1 and 3, with phase (L) connected to terminal 1 and neutral (N) to terminal 3.
The load connection wires are connected to terminal 2 and to the neutral terminal block (not supplied).

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.

Setting voltage limits
(factory setting 242 V / 198 V)
To see the upper limit press «+» button, lower limit press «-» button. To change use «+» and «-» buttons.
IMPORTANT. During voltage limits settings use technical documentation for protected equipment.

Menu

Use the «=» button to navigate through the menu. Use the «+» and «-» buttons to change the parame­ters. After first pressing parameter will flash, after second pressing it will change. After 10 sec after pressing – display returns to the mains voltage.
To browse the abbreviation expansion of parame­ters, use the «i» button.

Alarm log for 100 values
The device stores in non-volatile memory the voltage values at which the load was interrupted or overheat triggering «oht» (scan 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 «+» or«-».

The value of each alarm is accompanied by a single flash of display with its number, where «n 0» – is the newest 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.

Button lock
Hold down the «+» and «-» for more than 6 sec until the message «Loc»/«unLoc» appears on the screen.

View the temperature inside the case. If overheating has occurred and «oht» is displayed, press the «i». If there is no overheating, hold «i» for 24 seconds.
View the firmware version. Hold «i» for 6 seconds.
A tripping counter. Hold «i» for 12 sec. Viewing only.

Reset to factory settings

Hold «-» and «=» buttons simultaneously until the «dEF» message appears on the screen. When you release the button, the settings are reset and the device reboots.

POSSIBLE PROBLEMS, CAUSES, AND WAYS TO OVERCOME THEM

• At turning on neither the indicator nor the screen don’t light up Possible cause: there is no power supply voltage.
• It is necessary to: ensure supply voltage presence.
• Screen normal voltage level, 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; and 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 enclosure is above 80 °C and the Overheat Protection has tripped.

It is necessary to: check the tightness of the power wires in the device terminals; make sure that the power to be switched does not exceed the permissible load and that the connection cross-section of the wires is correct.
If the protection trips more than 5 times a day, the relay will lock and «oht» will be displayed permanently. Eliminate the overheating problem and wait until the temperature inside the relay drops below 60 °C – the relay will indicate this by displaying a dot at the end of «oht.» Then, to unlock, press any button on the relay.

The load is disabled, the screen displays «rEP»
The relay was locked to draw attention to the dangerous situation and protect the equipment.
Cause: the maximum number of frequent operations in case of unstable network has been exceeded.
Required: unlock the relay by pressing any button, then press «i» to find out the cause of tripping in the Alarm log. Take steps to correct the problem, if possible. Note that the relay will unlock automatically 1 hour after the «rEP» is triggered, this measure will keep your equip­ment partially operational until the network problem is corrected.

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.
