i. INT69Y motor protector
In addition to the temperature monitoring function of INT69, Hanbell also supplies INT69Y motor protector with the
monitoring functions of phase loss, phase sequence, motor temperature, discharge temperature as an optional
accessory.

Note
：
Electric plate with PT100Ω/PT1000Ω connection (B) shown in above diagram is optional accessory. Only
when customer chooses PT100Ω/PT1000Ω function, Hanbell will supply this type of electric plate.
Phase loss, phase sequence:
Phase sequence and phase loss monitoring functions are active during a 5s window 1s after compressor start
( power on L1-L2-L3). If one of these parameter is incorrect, the relay locks out ( contacts M1-M2 are open). The
lockout can be cancelled by mains reset of approx. 5s (disconnect L-N)
Note: To make sure phase loss and phase sequence protection function well, please connect L1, L2 and L3 to
motor side as figure shown above.
Motor temperature:
Motor temperature is constantly measured by a thermistor (PTC) loop connected on S1-S2. If any thermistor
exceeds its response temperature, its resistance increases above trip level and the output relay trips ( contacts
M1-M2 are open ). After cooling down below the response temperature, a 5min time delay is activated. After the
delay has elapsed, the relay pulls in again (The contact M1-M2 is closed). The time delay can be cancelled by
mains reset of approx. 5s (Disconnect L-N)
Note: When choosing aforementioned INT69 or INT69Y motor protection, Hanbell strongly recommends adding
“Shutdown Lock-out” function and restarting by manual reset after abnormal trip and troubleshooting to prevent
too frequent cycle of “abnormal trip → auto reset → restart.”
