Principle of Operation:

The relay can be configured in one of three programmable modes designated as “0100”, “0200”, “0300”. The difference in the functioning of DTDR when configured in the above mentioned modes is restricted to the manner in which its (NO) contacts of DTDR are reset.

DTDR, after sensing the operation (NO -> C) of a potential free contact (Timer Initiation Contact) connected to its terminals [6,7], starts decrementing its “relay operation timer” from an initial value. The initial value of the “relay operation timer” corresponds to “time delay setting”. After “relay operation timer” counts down to “0”. DTDR operates its NO contacts.

Description

DTDR reset operation in mode – “0100”: “0100” mode corresponds to “Hand Reset” mode. The NO contacts of the DTDR will remain in operated state until further human intervention. Following the operation (NO – > C) of DTDR contacts, DTDR can be reset by pressing “RESET” (RST) switch on the DTDR.

DTDR reset operation in mode – “0200”: “0200” mode corresponds to “TYPE-1 Self Reset” mode. Following the operation (NO -> C) of DTDR contacts, a “self reset timer” will start decrementing from a value equal to “Reset time delay”. When this “self reset timer” reaches its terminal count (‘0’), DTDR is reset.

DTDR reset operation in mode – “0300”: “0300” mode corresponds to “TYPE-2 Self Reset” mode. Following the operation (NO -> C) of DTDR contacts, DTDR transits to a wait state where it waits for the “Timer Initiation Contact” across [6,7] to change its state from “closed state TO Normally open state”. When “Timer Initiation Contact” across [6,7] changes state from “closed state TO Normally open state”, a “self reset timer” will start decrementing from a value equal to “Reset time delay”. When this “self reset timer” reaches its terminal count (‘0’), DTDR is reset.
