Timers and scenarios can be adjusted using the dials on the front panel of the relay. - Page 3 Table 1 continued Characteristics Values Item code RT-10 RT-10-2 RT-10-12-240 RT-10-12-240-2 Mechanical life, cycles 1 000 000 Number of switching contacts Rated load current, A 8 at 230V, AC1 3 in accordance with Interference immunity IEC 61000-4-4:2004 Max. altitude above sea 2000 level, m Degree of protection...
- Page 4 Indication Green "U" LED: constantly lit when the relay is powered. Red " " LED: flashes red during timer countdown. The relay is on, contacts 15-18 (25-28) are closed - constantly lit. The relay is off, contacts 15-18 (25-28) are open - does not light up. Attention! In order to repeat the cycle after power off, wait for at least 200 ms before reconnecting the supply.
- Page 5 Function diagram Function diagram Description Delay On (NOTC). After the relay is energized, a countdown (T) is started. During the count- down, relay contacts 15-16 (25-26) remain closed and contacts 15-18 (25-28) remain open (relay is off). Once the countdown is finished, contacts 15-16 (25-26) open, and contacts 15-18 (25-28) close (relay is on), remaining in this state until the relay is de-energized.
- Page 6 Function diagram Description Leading edge On / Trailing edge Delay Off. After the relay is energized, it remains in a steady state until a signal (S) is detected. As soon as the signal is detected, contacts 15- 16 (25-26) open, contacts 15-18 (25-28) close, and relay remains in the steady state while the signal (S) is being detected.
- Page 7 Function diagram Description Reappearance of the signal (S) while the countdown is running does not affect the execution of the relay scenario. Delay On (Leading edge) / Delay Off (Trailing edge).After the relay is energized, it remains in a steady state until a signal (S) is detected. Once the signal (S) is detected, a countdown (T) is started.
- Page 8 Function diagram Description Delay On One-shot (0,5s).After the relay is energized, a countdown (T) is started. During the countdown, relay contacts 15-16 (25- 26) are closed and contacts 15-18 (25-28) are open. Once the countdown is finished, contacts 15-16 (25-26) open, and contacts 15-18 (25-28) close for 0,5 s and then open again, remaining open for as long as the relay is energized.
