Motor Temperature Control via PTC Probe

As soon as the temperature returns to the correct value, the relay can be unlocked (reset), either by pressing the "Test/Reset" button (for at least 200 ms), or by closing a volt-free contact (for at least 200 ms) between terminal Y1 and T1 (without a parallel load). When a fault is detected, the "temperature" output relay locks in the open position, even if the "Test/Reset" button is pressed.

With memory ("Memory" mode)


Use of the "Test/Reset" Button

When the temperature is normal, pressing the "Test/Reset" button simulates overheating, the "temperature" output relay contact is open.

Without memory ("No Memory" mode).

In "Memory" mode, "fault" indication is locked and the button must be released then pressed again to reset the function. When a fault has been detected and the temperature has returned to normal, the "temperature" control relay can be unlocked (reset) by pressing the "Test/Reset" button.
