SEPHCO Digital 'Touch Type' Controls

MC12P Digital Controller

The MC12P controller features a touch type keypad and LED load display, built-in to load bank cable connection box or supplied loose for flush mounting and fitting into a remote location.

The MC12P controller offers simple operation of the load bank start up, kilowatt selection and load bank status. The unit automatically configures the load steps in the load bank to provide instant kilowatt response as selected by the Up/Down keys.

Other features include load bank "system check" which prevents loading in the event of fan cooling failure, fan reversal or high temperature.

The MC12P controller totally replaces outdated control devices such as toggle switches and push buttons.


SmartLoad LS800D Controller

The SmartLoad LS800D control uses the latest generation microprocessor with EEPROM memory for system back-up of operation parameters during power loss.

Advanced software programming provides a level of control not possible with any current sensing relays or PLC. By monitoring the generator set current via a appropriate C.T., the unit calculates the exact load required to precisely stabilize the generator set loading.

The linear hysteresis of the control ensures fast response and conditions the plant load accordingly by adding an appropriate load value from the
load bank to correspond with the controller's set value, generally set between 35% and 50 % of generator set rating.

Upon recovery of the plant load, the processor sheds loads from the load bank to maintain the current required. Connection for a voltage free signal is provided for interfacing with the building management system, transfer switch or generator start relay.

In the event of a utility power failure, occurring during auto operation, the voltage free signal disables the controller, instantly dumping of loads in the load bank and reinstating the "Auto Standby" mode for normal operation.


LS800D Soft Loading Capability


The LS800D "Soft " feature, ensures that overloading of the generator set does not occur during load bank startup. Loads are ramped up and down through an adjustable time sequence, each time the load bank is energized.

Similarly, the “soft” loading ensures that the generator set is not instantly unloaded when a sudden surge occurs in the system load. The provides smooth running for the engine avoiding unnecessary reaction to instant spikes.


Remote Control Manual Over ride and Genset Exercising Panel Model LS800MPE

The LS800MPE is an optional control panel added to the load bank installation for remote, manual overriding of the load bank.

Connection is by a simple three-core cable, connected to the load bank's auxiliary terminals. Featuring a touch-type keypad and LED display, the LS800MPE offers simple operation for manually controllability of the load bank.

Selection of operation includes Manual Loading, Auto-Load Shedding and Auto Genset Exercise
mode.The exercising function is programmable by setting up a load routine with time duration.

The LED display indicates the kilowatt value activated at the load bank during any of the switching operations. Additional LED's display mode selection and the status of the load bank, including fan-cooling fault.

Connection for a voltage free signal is provided for interfacing with the building management system, transfer switch or generator start relay.

In the event of a utility power failure, occurring during manual operation or auto exercising, the voltage free signal disables the controller, instantly dumping of loads in the load bank and reinstating the "Auto Standby" mode for normal operation.


SEPHCO RTSW Manual Control Switch

This economical range in the sizes up to 100kW Is controlled by rotary load selection switch located On the side of the control cabinet. The load sets are selected manually.
