Setting up a backup pump for your chemical metering application can save you from downtime having a backup pump set to automatically turn on when a primary pump is in an alarm situation for example a tube is failed critical chemicals will continue being injected there's no more rushing to job sites let's start by taking a look into the wiring schematic for setting up a backup home a diagram shows both contact closure wiring necessary for triggering the backup pump when the primary has failed as well as wiring layout for looping a 4 to 20 mili-amp signal if you're not planning on using a signal to drive your pump no sweat the contact closure wiring remains the same when wiring your contact closure you should connect your wires from the t3 input terminal used for dry contact in your primary pump over to the t8 output terminal of your backup pump t8 is labeled cc1 this means contact closure number 1 your positive red wires should be in the one position with your negative wire in the two position of the green terminal block are you using a 4 to 20 mili-amp signal to drive your pump Chemical output if so make sure to review this diagram you will want to run your positive red wire from your signal generator to the t1 terminal of your primary pump and secure the wire into the third position a second wire will be needed to run from the same t1 terminal but starting in the second position and running over to your backup pumps t1 terminal in the third position your third and final wire will run from your backup pump in the t1 terminal second position back to the negative black wire connection now let's see the wires connected onto the pump the contact closure wire is placed into the T 3 terminal of the primary pump while we have the primary pump open let's take the 4 to 20 mili-amp signal that has been wired up and place it into the t 1 input terminal you can see there are two separate wires exiting the terminal the red wire is connected to the 4 to 20 mili-amp generator and the black wire is leading over to the backup home T 8 is plugged in to complete the contact closure circuit from the primary pump over to this backup pump next the signal input is plugged into the t1 terminal a bottom wire connects back into the primary pump and the top wire completes the signal circuit by connecting to the negative input of the 4 to 20 mili-amp generator on the primary pump we're going to program the contact closure first you'll want to press the menu button and scroll down and select the output setup option select contact closure number 1 on the first menu item pump run stop press enter the menu will prompt you to set a delay for how long you'd like the pump to wait until n initiates press ENTER to exit now that the pump runs stop is selected for contact closure number 1 back out of the menu by pressing the down button until you reach the done option you can now escape out of the rest of the menus for the backup pump press menu and scroll to the input setup option scroll down to contact input most likely disable will be selected you want to press ENTER on clothes stop pump you can set any sort of delay option here press done to back out of the menu and escape out of the input setup in the main menu you will now want to select the output setup select contact number one select pump run stop choose a delay again we chose to remain at zero for an instantaneous start now back out of all menus as you can see when we return to the main menu our pumps are already configured to a 4 to 20 mili-amp mode refer to the manual or our other video which reviews how to configure this function once programmed and turned on the primary pump screen will remain green oh the backup pump will illuminate blue reading standby remote the backup pump is waiting for signal from the primary pump that has failed we test the pumps by simply pressing the stop button on our primary pump as you can see the pump that is waiting in standby mode immediately turns on with the first pump stops now kick back and relax you've got one less thing to worry about.
