Microprocessor based monitoring relay to measure moisture in a submersible pump. Due to the advanced design of the unit a high accuracy and safety is achieved. Response delay are incorporated to prevent nuisance tripping. The unit energises on application of supply. If the current through the probes is more than 20uA or the resistance is smaller than 10 Mohm, the relay will de-energise after 10 sec. The relay will energise if the current is less than 15uA and the resistance is more than 1.4Mohm.
Pulse Controlled Interval Timer – T1I_P
Microprocessor based pump protection relay capable of protecting a submersible pump against all major power line faults. The unit calibrates itself under normal running conditions and stores these parameters in non-volatile memory. The unit also incorporates a reset delay for under current situations to enable the borehole to replenish itself. In an over current situation the unit will retry three times to prevent permanent tripping with temporary blockages.
The XP404 is a fully programmable microprocessor controlled four digit counter / timer. The set value can be entered via the front membrane switch and the function, range, relay action and UP or DOWN count / time is set with an extended menu. The unit also incorporates a supply for a NPN proximity switch which can be used to pulse the counter.
