Оvervoltage protection for professionals
The MF multifunction relay ZUBR (hereinafter referred to as the device) is intended to protect single-phase electrical equipment from deviation from the set limits for voltage, current or power. By using the device, it is possible to limit the power consumption of remote equipment.
IN THE BOX
- Multifunction relay ZUBR MF 1 piece
- Technical data sheet installation and operation manual warranty card 1 piece
- The packing box 1 piece
IMPORTANT. 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. THE DEVICE MEASURES ONLY THE ACTIVE
POWER. The total power consists of active and reactive powers and can be
calculated by multiplying the voltage by the current.
CONNECTION SCHEMES
The supply voltage (100-420 V, 50 Hz) in which current and power will be monitored is applied to terminals 1 and 2, with the phase (L) determined by the indicator and connected to terminal 2, and neutral (N) to terminal 1. The connecting voltage wires connected to terminal 3 and neutral terminal block (not included).
IF A NEUTRAL TERMINAL IS NOT USED TO CONNECT A NEUTRAL WIRE TO THE DEVICE, the connection of the mains neutral wire to the load neutral in terminal 1 of the device is allowed only if it is crimped in the sleeve.
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 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 be equipped with standard mounting rail 35mm width (DIN rail). The appliance takes in width of 3 standard module on 18 mm. The height of the appliance should be in the range 0,5…1,7 m from the floor. The appliance is installed and activated after installation and inspection of the voltage.For protection against short circuit and excess capacity in circuit load necessarily need to set in front of the appliance, the automatic circuit- breaker (Scheme 1, QF ). To protect person from electric shock leak is set safety shutdown device(QD).Terminals of the device designed for wire cross section up to 16 mm Clean the end wires of 10 ±0,5 mm2. . It isadvisable 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.
WARRANTY TERMS
The warranty for ZUBR devices is valid for from the date of sale, provided that the instructions are followed. The warranty period for products without a warranty certificate is counted from the date of production If you continue to have issues with the device, please send it to a Service Center or to the store where you purchased the device. If your device is defective due to our fault, we will repair or replace it under warranty within 14 business days.Please see the full text of the warranty and the data you need to send to your Service Center on the website https://www.ds-electronics.com.ua/en/. If you have a warranty case, please, contact the General distributor in your area.

EXPLOITATION
After switching on, the relay immediately starts to display the mains voltage. If the voltage is within the permissible limits, the load is switched on after the set time. The screens will flash over last 3 seconds before switching on the load. The green indicator signals about the activation of the load. The values of the current and the active load power will appear on the corresponding screens. If the voltage deviates from the set limits, the load will be disconnected. If the current or power limits are exceeded, the corresponding screen will flash, and protection will be activated after the load has been disconnected. The relay will turn off the load.
All settings are stored in NON-VOLATILE MEMORY. When setting the voltage limits USE THE PROTECTED EQUIPMENT TECHNICAL DOCUMENTATION
Setting voltage tipping point (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
**Delay in the load starting after a failure (control is described in table
- ** After a voltage jump before the countdown for 1,5 seconds, and emergency situation will be displayed, then for 1,5 seconds the values of the mains voltage, the current and the active load power
If the set delay time is more than 6 seconds during the countdown, the current screen will display the remaining time before the load is switched on, the power screen will signal that the relay is in the countdown. The voltage screen is the active voltage during the countdown
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.
Viewing of firmware version
Hold the button for 8 seс. T « » ≡ he rated current of your MF relay will
be displayed on the current screen. The manufacturer reserves the right to
modify the firmware to enhance the device technical characteristics.
Reset to factory settings
Hold three buttons for 8 seconds till the sign appears on the screen. After
releasing the buttons the device will restart and reset the settings to the
factory settings.
Use the button to navigate through the menu « » ≡ (table ). Use the 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. 3 seconds after the last pressing of the buttons or by briefly
pressing the middle button, the relay will return to normal operation.
POSSIBLE PROBLEMS, CAUSES AND WAYS TO OVERCOME THEM
On the screen normal 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.
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.
The load is disabled, «oht» flashes on the screen
The temperature inside the housing exceeded 80 °C and triggered protection against internal overheating. The voltage screen is flashing «oht» once for 1 second, the current screen is displaying the temperature of the protection sensor, and the power screen is displaying the temperature in Celsius.
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. ‘t 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 Intemal overheating: the device will be unlocked in case if the temperature inSde will decrease to 60 •C (the «oht» stops flashing) and one of the buttons is pressed
Every 5 sec the screen displays «Ert»
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.
The load is disabled, the screen displays « »
Cause: the triggered overcurrent protection or the active power protection in succession exceeded the set value. The relay is blocked.
It is necessary to:
- make sure that the current and active power trip limits are set correctly;
- if necessary, increase the current and active power pickup limits according to the requirements of the connected load, If this does not contradict the wiring section;
- make sure that the required trip limit is set for both current and active power;
- unlock the relay by pressing any button.
