How does the ON delay function operate in this timer?

The ON delay function initiates the countdown immediately upon energisation, starting with contact 15-16 closing. After the pre-set time elapses, contact 15-16 opens and a fixed 50 ms lapse begins before contact 15-18 closes, ensuring no short-circuit occurs.

What are the considerations for resetting the device after use?

Upon de-energisation, both indicator lights turn off after 250 ms, signalling that the device has reset and is ready for a new cycle, facilitating a smooth transition between operations.

What factors can affect the time delay settings and how can they be accounted for?

Temperature variations can influence time delay settings, as the device has a drift rate of -0.2% per °C. It's advisable to consider this drift if adjustments are made significantly outside the standard operating temperature range for accuracy.
