Transcript (auto-generated):

The flex pro peristaltic metering pump features four input signal capabilities for external control in this video we will be reviewing the 4 to 20 milliamp input mode setup and function press and release select run mode to change input option press and hold select run mode once for 2 20 milliamp input is displayed at the top left corner of the screen upon entering the mode use the up and down arrows to adjust the minimum and maximum values of the milliamp signal and percentage of motor speed press ENTER to save changes continue the process until all four screens have been configured the pumps output speed adjusts automatically based on the value of the 4 to 20 milliamp signal in this example 4 milliamps result in an output of twenty percent and 60 milliamps orzel in an output of seventy percent the linear pump output slope will be created if the pump receives more than 60 milliamps the output will remain at seventy percent alternatively the pump can be configured by pressing the menu button then selecting input set up input modes and then 4 to 20 milliamp input at this point execute the same as the previous method to exit select escape at the bottom of every screen menu until you see the run mode screen displayed here is an overview of the required tools and parts to connect the 4 to 20 milliamp cable to the a 3 flex pro pump first remove power to the pump remove the liquid tight seal from the junction box enclosure with a flathead screwdriver next remove the four screws with the provided allen key unplug the power from the terminal board install the liquid tight connector seal this is provided in the shipping kit with every flex pro pump now we run the 4 to 20 milliamp cable through the connector press the 4 to 20 milliamp cable connector into the t1 terminal block also reinstall power to the terminal board reinstall the junction box to the pomp finally tighten liquid tight connectors after the pump has been configured for the 420 milliamp signal and the 4 to 20 milliamp wire is connected to the terminal board we can use a 4 to 20 milliamps signal generator to test the pump here a fluke device is being connected to the 4 to 20 milliamp cables apply power to the pump in the fluke device press the start button on the pump and activate the fluke meter notice how the pump operates in relation to the output signal from the 4 to 20 milliamp generator the pump is operating correctly.
