DIN RAIL 8 & 11 PIN PLUG IN DEDICATED VOLTAGE, SINGLE TIME RANGE, MAINS RESTORATION “BROWN OUT” TIMERS

Din rail mounted or 8 & 11 pin plug in SPCO and DPCO “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 engineers’ site visits, just to reset and restart a control system. By monitoring the supply these tried and proven Foxtam units will provide the “auto restart” signal to reset and restart the control system without the need for a site visit. For added convenience DPCO units are also available with the extra contact used as say a telemetry output to notify an operations centre that an incident has occurred.

These timers are designed and operate in such a way that they reset as quick, if not quicker, than standard contactor and relay coils. They are offered in a choice of three functions:

Delay On “A” function - on the application of the supply voltage the relay will energise after the set time delay. Should the supply then be lost for 1 cycle (20mSec)* and/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.

Pulse “H” function - on the application of the supply voltage the relay will energise for the set delay time and then deenergise. The timer will then remain de-energised until reset by switching off normally, or by the loss of the supply for 1 cycle (20mSec)* and/or dip below 80% of the nominal supply voltage. The relay will again energise for the set delay time on restoration of a healthy supply voltage.

Delayed Pulse “Q” function - on the application of the supply voltage the relay will after the set delay time pulse on for a fixed time of 300mSec. Should the supply be lost for 1 cycle (20mSec)* and/or dip below 80% of the nominal supply voltage the timer will be reset and after restoration of the supply the timer will commence another set delay time after which the relay will energise for 300mSec.
