CONNECTION SCHEMES

• The supply voltage (100–420 V, 50 Hz), in which the current or power is measured, is supplied to the terminals 1 {phase, L) and 2 ( neutral, N). If a circuit without a neutral bypass through MF2 is used, the neutral wire can also be connected to terminal 4.

• The connecting wires of the load phases are connected to the corresponding terminals 3, 4 (phase (L) is connected to terminal location 3, and zero (N) is connected to terminal location 4).

• Scheme 1. Option of wiring diagram with a neutral bypass through MF2-50 red

• Scheme 2. Option of the connection diagram with a neutral bypass through MF2-50 red

• 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.

• CURRENT AND POWER IS MEASURED at the phase input of the device.

• All settings are stored in NON-VOLATILE MEMORY

EXPLOITATION

• If the voltage is within acceptable limits, after the set delay time, the load is turned on and the green indicator starts to glow.
• When switched on, the device first displays the parameter symbols, then the parameters themselves.
• In case of an emergency, the alert type and its meaning will flash on the screen.
• Use the « » button to navigate through the menu (table 1 ). To change the parameter, press «+» once, the flashing value of the parameter can be changed with «+» and«-». 5 seconds after pressing return to the settings menu, after other 5 seconds to the indication of line parameters.

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.
• WHEN SETTING THE VOLTAGE LIMITS USE THE PROTECTED EQUIPMENT TECHNICAL DOCUMENTATION

Delay in the load starting after a failure
(factory setting 3 sec)

• Following the end of an emergency, the device does not immediately load the connected equipment, but after a set turn-on delay time.
• After a power surge, the device will display the type of failure, then the current line voltage and start the countdown. If the delay time is set to less than 6 seconds, the device will skip this step.
• In case of a long failure, the device will display the type of failure and its meaning, and the countdown will start when voltage stabilizes.

Viewing of temperature of a thermal protection sensor

• It is required to control heating inside the case.
• For example, to assess the degree of heating inside the case or to prevent overheating. To view hold the button « » for 20 sec.

Log for 100 accidents

• The device stores in non-volatile memory the last 100 values of voltage, current, power or thermal protection operation «oht», where «n 0» is the last entry, «n99» is the oldest).
• To enter the log, hold «i» for 3 seconds, the device will display the number of alarm entries in the log. After release, details of the last alarm (number, type and value) are shown.
• To view the log press the «+» or«-» buttons.
• To reset the log while viewing it, hold down «+» and «-» simultaneously until «Err rSt» appears. After releasing the buttons, the log will be cleared.

Examples of emergency log entries:

• View all measured parameters
  Hold «i» for 6 seconds to start viewing. The upper screen will display the parameter, while the middle screen will display its value. Use «+» and «-» to switch between parameters. To quickly exit the view, press «+» and «-» simultaneously. 30 seconds after entering the view mode, the device will return to displaying the measured parameters.

• Locking the controls
  To lock (unlock), hold down the «+» and «-» buttons for more than 6 seconds until the message «Loe» («unloc») appears on the screen.

• Viewing of firmware version
  Hold the button «i» for 9 sec. The version will be displayed as running letters. The manufacturer reserves the right to modify the firmware to enhance the device technical characteristics.

• A tripping counter
  To view hold the button «i» for 15 sec. It is used to estimate the number of switching’s of the power relay and its wear.

• Reset to factory settings
  Hold the button « » for 30 seconds till the «dEF» sign appears on the screen. After releasing the buttons the device will restart and reset the settings to the factory settings.

POSSIBLE PROBLEMS, CAUSES AND WAYS TO OVERCOME THEM

• Frequent load trip
  Possible cause: underestimated (overestimated) value of the upper (lower) limit. Exceeding the set current limits or selected power.
  It is necessary to: check which line parameter is triggered, and set the limits of this parameter so that the protected equipment is tolerant of such values.

• After turning on 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 screen do 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. «oht» and the temperature of the thermal protection sensor flash 1 time/sec on the screen.
  • Possible cause: inner overheating of the device to which can lead: bad contact in the terminals of the device, high ambient temperature or incorrectly selected cross-section of wires for connecting.
  • It is necessary to: check the tightness of the power wires in the terminals of the device and make sure that the cross section of the wires for connection is selected correctly.

• Feature of protection against internal overheating:
  the device will resume operation if the temperature inside the housing drops below 60 ‘C. If the protection is triggered more than 5 times within 24 hours, the device will lock
  (then «oht» is displayed permanently, and the bottom two screens will keep flashing), until the temperature inside the housing drops below 50 ‘C (the display will not flash) and one of the buttons is pressed.

• The load is disabled, the screen displays «rEP Err»

  • Possible cause: the maximum number of consecutive trips for exceeding current, power or 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.
