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. Failure to do so could
result in inadvertent trips or failure to trip at appropriate speed
resulting in property damage, injury, or death.
1. Switch the keyswitch to the PROGRAM position.
2. Press the MENU key to step through the parameter menu to the first tunable
parameter, TRIP SPEED SETPOINT.
3. Use the CURSOR RIGHT, ADJ UP, and ADJ DOWN keys to enter the
proper rpm for your preferred TRIP SPEED SETPOINT.
4. Press the MENU key to step to the next tunable parameter, MPU FAILED
SETPOINT.
5. Use the CURSOR RIGHT, ADJ UP, and ADJ DOWN to enter the proper
rpm for your preferred MPU FAILED SETPOINT.
