Pulsar Ultra 5 - Pump Controller Programming (replacing float switches)

- Customer unhappy with maintenance and failure rate of their float switches.
- They want to retro-fit an ultrasonic controller in the form of the Pulsar Ultra 5, as a replacement for their float switches.
- The customer would like to integrate the Ultra 5 into an existing control panel, leaving the wiring as-is to avoid complications.
- Note: This isn’t the convention way of doing pump control, typically the customer will use one relay for one-pump, which will control both the on and off set point .

at roughly 4:00 you say that you selecting "control down", however he goes onto press '2' which as far as I can see is "control up". can you clear this up?

Hi Josh, well spotted !
The purpose of selecting 'control up' or 'control down' is to guide the unit with regards to where the on/off set points should be, in relation to the operation span entered. However, it really doesn't matter for this specific application, as 2 relays are 'control down' relays (the pump lead and lag on points) and 1 relays is a 'control up' relay (off point for both pumps), this is because we are replacing float switches directly.
Relay 1 energizes ON to turn off both the lead and lag pumps (relay OFF point higher than the ON point)
Relay 2 energizes ON to turn on the lead pump on (relay OFF point lower than the ON point)
Relay 3 energizes ON to turn on the lag pump on (relay OFF point lower than the ON point)
But we will get this video updated and republished. Thanks again for spotting.
