Motorscope S2LC

The Motorscope S2LC is a compact dual motor protection unit with an integrated level controller and more.

General

The Motorscope S2LC is a dual pump protection unit (2 Supra relays) with level control features.

Our compact S2LC replaces this relay-based control panel!

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)
  • Not against lightning
Features
  • Filling or Emptying
  • Float Switches or Probes
  • Manual or Auto

The two Supras share an alarm output for:

  • Over Current
  • Over Power
  • Minimum Phase Angle
  • No Current
  • Uncalibrated
  • Controller Error

Shared level and pump alarm output for:

  • Either high or Low level
  • Oil sump water detection

Each Supra has its own Recover Timer to allow the sump to fill up before a restart attempt is made (after a run-dry condition).
These timers are manually adjustable from 4 minutes to 16 hours.

Each Supra has a real-time clock. This allows each unit to store the date and time (year, month, day, hour, minute) of each one of the last 43 trips.

Built-in User Interface Options

 

The S2LC has a dedicated serial port for each Supra to which the following Built-in User interface options could be connected:

  • A single Mobi Board (Bluetooth Interface to App) which can manually be moved from one Supra’s serial port to the other.
  • Two Mobi Boards (one for each Supra)
  • A single Built-in Optimizer which can manually be moved from the one Supra’s serial port to the other Unfortunately the Built-in optimizers are too big to allow two of them to fit into each-other on the S2LC therefore no dual Built-In Optimizer option is available.
