Supra R3 Motorscope (upto 37kW)

Protection Relay for 400/525VAC, 6→37kW motors

 

The Supra-R3 is a Motor Protection Relay which measures Volts, Amps and Power Factor with limits on each for protection on Induction motors. These limits are checked continuously.

For the user-convenience sake, the Supra-R3 also includes Wi-Fi which could be used for remote start/stop and motor status monitoring.  The Wi-Fi protocol can be configured for:

  • MQTT (sparkplug B), which directs all status change messages to our own free to use remote monitoring website or
  • MODBUS (version 3 RTU) client, which can be continuously polled by a MODBUS server to display the motor status / remote start / stop the controller straight from existing Automation Control software.

It also includes configurable automation timers which can either be used as a scheduler (eight, seven day, twenty four hour schedules) OR sequencer (seven sequential ON / OFF timers).

  • The sequencer could be used to implement a delayed startup after Power ON. This function is used when multiple pumps are connected to a single power line. Bringing down the starting current on the line dramatically.
  • The scheduler could be used for planned motor runs with a specific start and stop time to let the motors run for example at times when electricity is priced at a lower rate.

Auxiliary input for peripheral control. For example a float switch to keep a tank or dam full of water.

And last but not least a recovery timer for the restart of a motor after a low power (Run Dry) trip to allow for the recovery of a sump or borehole level.

All Motorscope products can be monitored with our mobile application called NcsToolbox. It is already available for Andriod device via the Google Play Store and we are presently working on iOS mobile application for Apple devices. Most prominent features of the NcsToolbox Mobile Application:

  • Completely ad free and works with Bluetooth, which means that it does not require any active internet connection at site and no annoying advertisement interruptions.
  • Has a calibration wizard to improve user friendliness.
  • Parameters can be set without an extra tool.  All you need is a Smartphone.
  • Trip data can be downloaded in the field and shared immediately (or saved and shared when connected with internet again) with WhatsApp, Telegram or Email. This helps with fault finding and warranty claims.

Features:

  • Phase rotation, Voltage, Current and Wattage limit monitoring
  • Built-in Wi-Fi
  • Free basic status reporting and ON/OFF control via website.
  • Scheduler and sequencer timers that work when Supra-R3 is not connected to the network
  • Underload recovery timer
  • Auxiliary inhibit
  • Real time clock
  • Reset input (for star / delta or soft-start installations)
  • Alarm Relay
  • Event Logging
  • User friendly fine-tuning / log downloads via Mobile Application.

Additional information

Protection

Over-load (e.g. pump jammed)
Under-load (e.g. run-dry)
Over-Voltage
Under-Voltage
Phase Failure (e.g. a wire is cut)
Phase sequence changes (e.g. after a power failure, the phases are swapped)
Phase Imbalance (e.g. one of the phases carries more load than the other two)
Motor wire Insulation Test: Before starting the motor, the B110 tests the motor wires to verify that none of them are down to earth.
Not against lightning

Features

RECOVERY TIMES: The Supra has a Recovery Timer to allow a bore-hole to fill up before a restart attempt is made (after a run-dry condition). This timer is manually adjustable from 4 minutes to 17 hours.

AUXILIARY INHIBIT: The Supra has an Auxiliary Inhibit input which stops the motor when the circuit between AUX and COM is OPEN.
This input may thus be used to remotely stop the motor.
For example:A normally closed pressure sensor may be connected to this input. When a specified pressure is reached, the connection will open and the Supra will stop the motor.

REAL-TIME CLOCK: The Supra has a real-time clock. This allows the unit to store the date and time (year, month, day, hour, minute) of each one of the last 100 trips

RESET INPUT: This input is used to keep the controller in the reset (no fault recognition) state. In applications where a soft- or star-delta starter is used, the controller can be held in reset for the duration of the start-up period.

SCHEDULAR: Timer function with 8 timers. 7 Day 24 Hour timers. Setable with a start time and a duration time.

SEQUENCER: 6 Time functions that begins at Motorscope start-up. With a ON or OFF duration.
Example: 10sec Delay when power comes up after load shedding for voltage to stabelize.
