MOTOR GP-PISTON 1560761 - Caterpillar

standard configuration for the EMCP 3.2 and for the EMCP 3.3 has only one "Programmable Trip Point" function block. The "Programmable Trip Point" is configured to respond to the %KW of the generator set.Note: The "Programmable Trip Point" feature is not available on the EMCP 3.1 control. The EMCP 3.1 does not monitor power.Note: The "Programmable Trip Point" function cannot be configured to act upon a different parameter from %kW. If a different capability is desired, a custom flash file must be ordered. Contact your technical communicator for details.The set points of the "Programmable Trip Point" are configured by default. If the %kW exceeds 90 percent for 10 seconds, then the output of the "Programmable Trip Point" will become true. The output of the "Programmable Trip Point" will remain true until the %kW drops below 85 percent for 1 second.The output of the "Programmable Trip Point" function can be configured by either of the following:
"Digital Selector 2" to "Relay output 4"
"Digital Selector 7" to "Digital (transistor) Output 1"The set points in the "Programmable Trip Point" function can be changed with the use of the EMCP 3.Programmable Trip Point Function Trigger Condition (Default = Trip Above Threshold) - Selects whether the output will be active if the value is above or below the threshold.Programmable Trip Point Function Percentage Threshold (Default = 90%) - The threshold that the measured parameter must pass in order to change the state of the output. In the default case for %kW, this value is 90 percent of rated kW.Programmable Trip Point Function Hysteresis Percentage (Default = 5%) - Once the output is on, the value must exceed the threshold by the default value before the output turns off again. In the case of the default %kW, the 5 percent value causes the relay to remain on until 85 percent of rated kW is reached. Therefore, if the rated kW is 90 percent, then the output will not switch off until 85 percent is reached. This hysteresis is used to ensure that a value close to the threshold does not cause the output to toggle on and off.Programmable Trip Point Function Trip Activation Delay Time (Default = 10 seconds) - The time that the value must exceed the threshold before the output of the block becomes active. The activation delay time is used in order to ensure that the momentary transients do not trip the relay.Programmable Trip Point Function Trip Deactivation Delay Time (Default = 1 second) - The time that the value must return past the hysteresis threshold before the output of the block becomes inactive again. The deactivation delay time is used in order to ensure that the momentary transients do not deactivate the relay.
