Tele, 12V ac, 400 V ac Process Pump Controller, 55 °C, IP40, IP20

Pump control, Alternating/parallel

• Alternated access of two pumps or other devices
• Even distribution of duty
• Parallel duty at high demand
• Operation using 1 or 2 input signals (two modes of operation)
• Timing offset of the two loads to avoid water hammer effcects
• Supply voltage selectable via TR2 power modules
• 2 separate change over relays for device control
• Width 22.5mm
• Industrial design
• Task
• Two pumps are installed at a sewage pumping station that are to be run alternately for equal periods to ensure equal wear.
• Solution
• The pump switchover system activates the pumps alternately, if needed, the second pump can also be activated so that both run at the same time (parallel operation)
• Use/value
• Equal wear, and therefore longer service intervals for both pumps
• Minimised pump failures through nearly equal number of operating hours
• Peak load coverage
• Zero-voltage safety in the event of power failures
• Applications
• Centrifugal Pumps
• Sewage Pumps
• Water & Waste
