Din rail mounted SPCO “mains restoration auto restart timers”. The voltage and supply sensing built into these units are designed to sense voltage dips and momentary loss of supply referred to as “Brown Outs”. This phenomena is a particular threat in the water industry and regularly occurs at remote pumping locations, especially during electrical storms. Left unchecked, a supply dip can “lock out” all or part of a control system, causing system malfunctions over a wide area necessitating engineer’s site visits, just to reset and restart a control system. By monitoring the supply these tried and proven units will provide the “auto restart” signal to reset and restart the control system without the need for a site visit.
These timers are designed and operate in such a way that they reset far quicker (1mSec), than standard contactor and relay coils. They are offered in a choice of three functions:
Delay On “function 4” – on the application of the supply voltage the relay will energise after the set time delay. Should the supply be momentarily lost or dip below 80%* of the nominal supply voltage, the relay will de-energise and will commence timing again when the supply voltage is restored within 85%* or better of the nominal supply.
Pulse “function 5” – on the application of the supply voltage the relay will energise for the set delay time and then de-energise. The timer will then remain de-energised until reset by switching off normally, or by a momentary loss of the supply or dip below 80%* of the nominal supply voltage. The relay will again energise for the set delay time on restoration of a supply voltage within 85%* or better of the nominal supply.
Delayed Pulse “function 6” – on the application of the supply voltage the relay will after the set delay time pulse on for a fixed time of 500mSec. Should a momentary loss of the supply occur, or dips below 80%* of the nominal supply voltage the timer will be reset and on restoration of a supply voltage within 85%* or better of the nominal supply, the timer will commence with another set delay time after which the relay will energise for 500mSec.
