Product description

Electronic monitoring of motor currents protects the pump from dry running, overheating and overload.

If the above mentioned operating states are not absolutely impossible with your installation, you should use an electronic process monitor to switch off the pump before it is damaged. Such monitors will not only avoid damage to the pump, but also downtime and costs resulting thereof. At the same time, the monitor checks the pumping process for the set delivery rate. Once the cause of a malfunction is eliminated, the pump is immediately ready to continue operation. The process monitor is easy to install into the pump's power supply unit. As it is not necessary to build it into pipe runs, this process monitor also is ideal to retrofit existing installations. Four different types of process monitors are available:

RPR CONTROL 100-1
to be built into control cabinets (mounted on top-hat rail) without programming unit.

RPR CONTROL 100-2
to be built into control cabinets (mounted on top-hat rail) with integrated programming unit.

RPR CONTROL 100-3
Field device with power section of up to 4.0 kW (up to 7.5 kW optionally available),
mounted in an IP 65 casing for installation in the field (e.g.at the filter), complete with indicating lamps and push-button but without programming unit.

SEPARATE PROGRAMMING UNIT
Hand-held appliance with cable and plug to programme the switching thresholds of RPR-Control 100-1 and RPR-Control 100-3.

FUNCTION
An overload controller with analogue output monitors the actual
power of the pump motor. There are four switching thresholds defined:
- dry-running (fault, the motor is switched off);
- overheating (fault, the motor is switched off);
- overload (fault, the motor is switched off);
- filter contaminated (warning).

The switching thresholds are user-programmable.
Also included is a real-time clock with elapsed-time meter, e. g. to monitor maintenance intervals.
