Load Limit Sensing Control System GLR

A machine’s efficiency is directly related to the exploitation of the diesel

engine. The load limit sensing control system regulates the decrease ofperformance. A motor overload is thus hindered and the motor outputcan be used optimally in all areas.Its versatile connection and functional options make the load limitsending control system applicable for a wide range of machines.

The GLR controller is constructed based on the hardware platformSGR. The hand terminal MT or the PC program ConDoc - Con-trol&Document®m serve to input the parameters.

GLR Performance features

• The rotary frequency set value is set using two potentiometers, an overriding control system (PLC) ordirectly as a fixed value.

• The actual rotary frequency is measured from clamp W, via a pickup sensor or using the SAE-J1939 CAN interface.

• The diesel motor is driven via a voltage output, a PWM output, an actuator or using the SAE-J1939CAN interface.

• Errors are indicated via a switch output.

• An automatic learning function supports the recording of the characteristic diesel curve.

GLR Functions

• The entire control pattern can be individually adapted to match the machine.• The automatic idle running lowers the diesel rotary frequency in a settable period.

• The economy function and the excess temperature function both reduce the power consumption ifrequired.

• The operation mode "automotive" - automatic pump adjustment using the setting values – makesthe operation of the machine considerably easier.

SGR Hardware

The control system is protected by robustaluminium housing.
