Supra Motorscope (upto 37kW)

R4,336.00

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

Description

The power used by a working system varies with the application but must stay within safe limits.  Power consumption outside of this range indicates a faulty motor or system. The load or power consumption is measured at the input to the motor.  When the calibration button is pressed, with the jumper in place, the MOTORSCOPE defines the safe range for the system.  The motor must, at that time, run under normal working conditions.  The power supply has to be correct and stable, this is checked continuously.

The MOTORSCOPE keeps the motor running as long as the safe limits are not exceeded. The MOTORSCOPE has a RS232 output for serial communication with our OPTIMIZER or a PC.  The OPTIMIZER is used to improve settings, as an installation aid and for more detailed fault indication.  The OPTIMIZER can carry the data of the last 43 motor stops to be transferred to a PC or laptop.

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 16 hours.
AUXILIARY INHABIT: 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 43 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.
