About the 5466-318

Designed by Woodward Inc for the MicroNet Digital Control Series, the 5466-318 module was designed as a Triple Modular Redundant (TMR) Kernel Power Supply (P.S) module.

When this module is installed it will be used in applications that operate on a MicroNet TMR system as one of three kernel power supplies.

When installed this module will be inserted into the first slot of the kernel section.

Please note that prior to removing a module such as this, all modules within the MicroNet TMR Kernel Power supply must be removed.

The physical makeup of the 5466-318 module is metal and only has one LED on the front faceplate of the module.

The LED on the faceplate of the module is used to indicate the Power Health supply of the device.

This module will operate on a power supply of twenty-four volts of direct current which comes from the MicroNet main power source.

After the power supply has been received from the main MicroNet power source it will regulate it to either 10 A or 5 VDC for the remainder of the kernel section.

9907-147

Model 9907-147 uses magnetic pickups to monitor primer speed for overspeed conditions.

Devices in this series are susceptible to electromagnetic interference, vibration, moisture, and temperatures outside of the operating temp range of –25 to +60 °C (–13 to +140 °F).

ProTech overspeed protection models should be installed in locations that allow adequate ventilation for cooling, space for servicing, and away from direct sunlight, and away from high-current or high-voltage devices.

9907-147

This de-energize-to-trip system has a 100 Hz to 32 kHz speed-sensing frequency range and a ±(0.05% x Trip Point in Hz +2 Hz) accuracy rating.

Overspeed detection functions are carried out by three individual speed-sensing units, which act independently to monitor speed and perform speed calculations.

The three units are in a two-out-of-three vote configuration, so a prime mover trip relay will only occur if overspeed conditions are detected by at least two of the units.

The trip-point frequency range of ProTech overspeed protection model 9907-147 is 250 Hz to 25 kHz.

Trip set points are programmed for each of the units separately (they must be programmed identically for accurate outputs) using the operator interfaces.

There is one interface per speed-sensing unit. Each one has:

Two-line by 16-character LCD display

Touchpad

Potentiometer

LED indicators

Alarm output

Programming and testing functions are locked to prevent unauthorized changes.

One key switch to move between MONITOR mode and PROGRAM mode is connected to all three units.
