Grundfos- PM Electronic Pump Controller
The PM 2 is the all-round control solution offering adjustable start at 1.5 to 5 bar. This enables customisation to different types of installations and desired comfort level. The start pressure is set by means of DIP switches located behind the control panel whereas the current pressure is indicated on the LED display on the front of the PM 2. The PM 2 starts the pump when the start pressure is reached, and the pump keeps running as long as there is a flow. The PM 2 can be optimised for operation with an external pressure tank by enabling the 1 bar differential-pressure function. This function significantly reduces the number of operating hours of the pump in installations with pressure tank.
*Joint Screw:1inch (25mm)
*The PM 2 has some additional functions which can be enabled and disabled with DIP switches located behind the control panel.
*Auto-reset : When the auto-reset function is enabled, cycling and dry-running alarms will be automatically reset. N
* Anti-cycling :To avoid inadvertent starts and stops of the pump in case of a failure in the installation, the anti-cycling function can be enabled. The function will detect cycling if it occurs and stop the pump with an alarm
*When the auto-reset function is enabled, the pump will be restarted automatically after 12 hours in alarm condition.
*Maximum continuous operating time (30 minutes) When this function is enabled, the pump will be stopped when the pump has been running continuously for 30 minutes. The purpose of this function is to avoid unnecessary water and current consumption, e.g. in case of pipe fracture or considerable leakages.
*Free choice of installation position
*Flexible power supply
*Rotary outlet connection
*Internal pressure tank
*Suitable for power supply from petrol generators
*Pump running indication
*Rotary outlet connection.
Typical applications are water supply systems and rainwater systems in :
* Irrigation and Gardening
*Liquids- Clean, thin, non-aggressive and non-explosive liquids without solid particles or fibres that may attack the unit mechanically or chemically such as municipal water and rainwater.
This controller comes Pre-wired. It has a standard 3 pin plug for the mains and a 3 pin receiver which allows for a 3 pin plug from the pumps motor to connect directly in to the controller.
