MT-W...M time relays Time functions F0 – OFF - Constant service off. F0 function can be turned on at any time, during feeding the time relay with Un voltage. Turning on F0 function during carrying out any time function will cause the function to stop as well as constant operating relay R off (LED diode ”R” is off). Function F0 is activated by pressing ”F/T” button for a longer time (more than 2 seconds) and selecting F0 function. Confirm this function with red button ”OK” (after confirmation display will show digit 0). Exiting the service function needs a longer pressing of ”F/T” button - until...

MT-W...M time relays Time functions F6 – Wu(S) - ON for the set interval, with time measurement stopped with contact S closing. Turning on the feeding voltage U causes immediate turning on the operating relay R at the set time T1 (display shows vertical strip spinning to the right, LED diode ”R” is on). If the control contact S is closed, measuring T1 time will be stopped (display shows two horizontal strips) until the moment when control contact is opened. Opening contact S starts further measuring of T1 time. After finishing measuring T1 time the operating relay turns off (display shows ”End”,...

MT-W...M time relays Time functions F13 – EWa - OFF delay and breaking time delay with opening of the control contact S. Independent settings of T1 and T2 intervals. F16 – EWf - ON delay and OFF delay with the control contact S. Independent settings of T1 and T2 intervals. Time relay input is powered by voltage U in a constant way. Closing the control contact S causes immediate turning on the operating relay R (display shows two horizontal strips, and LED diode ”R” is on). Opening the control contact S starts measuring the time T1 (display shows a vertical strip spinning to the right), and after...

MT-W...M time relays Time functions F18 – Pi(S) - Cyclical operation pulse first. Independent settings of T1 and T2 intervals. Possibility of turninig on or omitting T3 time. Possibility of stopping and resuming cyclic work by control contact S. F19 – Pp(S) - Cyclical operation pause first. Independent settings of T1 and T2 intervals. Possibility of turninig on or omitting T3 time. Possibility of stopping and resuming cyclic work by control contact S. Turning on the feeding voltage U starts cyclic work from turning on the operating relay R for the T1 time (display shows a vertical strip spinning...
