Manual 85204 ProTech 203 Overspeed Protection System Chapter 4. Configuration and Operation Figure 4-1. ProTech 203 Front Panel ® The ProTech 203 system can be operated in one of two modes, MONITOR or PROGRAM. Although the system will "run" in either mode, it is recommended that the unit be placed in the PROGRAM mode only during configuration and then placed in the MONITOR mode during normal operation. - Page 20 ProTech 203 Overspeed Protection System Manual 85204 PRESENT SPEED is the first parameter displayed. Each subsequent press of the menu key displays the next parameter in the list. Appropriate descriptive units for each parameter are also displayed. When the keyswitch is in the MONITOR position, the CURSOR RIGHT, ADJ UP, and ADJ DOWN keys have no effect.

Page 21: Programming
Manual 85204 ProTech 203 Overspeed Protection System Programming Programming of the ProTech 203 system consists of entering values for all the tunable parameters. The procedure for programming each speed-sensing unit is as follows: In order to ensure proper functioning of the ProTech 203 system, it is imperative that the tunable parameters in each of the units are programmed to result in identical trip points. -

Page 23: Operation
Start-up The ProTech 203 system allows two methods for turbine start. The "TIMER STARTS ON RESET" menu option determines which method is used. The default setting for this option is "NO", which provides separate reset and start functions. -
Page 24: Figure 4-3. Method 2 Block Diagram
ProTech 203 Overspeed Protection System Manual 85204 If the unit is being restarted after a normal rolldown (that is, there was no trip), the unit does not require a reset. The MPU fail trip is overridden because the MPU fail timer is cleared whenever speed exceeds the MPU fail set point. The MPU fail timer should be started by the operator when the turbine is ready to be started again. - Page 25 Manual 85204 ProTech 203 Overspeed Protection System When the "TIMER STARTS ON RESET" option is set to "YES", the "ALM IF SPD < MPU FAIL SETPT" option is active. If "ALM IF SPD < MPU FAIL SETPT" option is set to "YES", the alarm relay de-energizes whenever speed is below the MPU fail set point.
- Page 26 ProTech 203 Overspeed Protection System Manual 85204 Overspeed Test The overspeed test function is activated when the keyswitch is in the PROGRAM position and the operator presses and holds the OVSP TEST button on the touchpad. The microcontroller switches the source of the MPU signal from the MPU input to an on-board oscillator.
