j. INT69HBY motor protector
Hanbell develops an optional accessory, INT69HBY motor protector, of which major functions are the same with
those of INT69Y: monitoring of phase loss, phase sequence, motor temperature, discharge temperature but with
manually reset function.

INT69HBY & PTC temperature sensors connection diagram
Other major functional descriptions are as follow:
1. When supply voltage is applied, the output relay pulls in after an initialization period of approx. 3 seconds,
provided all thermistors lie below their rated response temperature.
2. 1 to 9 PTC thermistors with varied rated response temperatures can be connected in series to the input
terminals.
3. If any thermistor resistance increases above trip level the relay drops out. This failure results in a lockout. (5
minutes delay for 1st PTC failure, 60 minutes delay for 2nd failure, lockout for 3rd failure.)
4. If a rapid temperature increase is detected (locked rotor condition), the output relay drops out. This failure results
in a lockout.
5. The phase monitoring function is active 1 second after motor start during a 10 second window. Incorrect phase
sequence results in lockout trip. Phase loss results in lockout trip.
6. Lockout and time delay can be cancelled by mains reset of approx. 5 seconds.
7. To avoid nuisance tripping due to reverse running after shutdown (pressure equalization), the phase monitoring
function is only re-enabled approx. 20 seconds after motor stop.
8. A twin LED (red / green) provides operational information.
9. The relay is fed out as a N/O dry contact, which is closed under good conditions.
10. Sensor and supply circuits are galvanic isolated.
11.The motor protector is not suitable for use with frequency converters.
