KRIWAN 31A634 INT69 Y Diagnose (AC 24V)
The KRIWAN 31A634 compressor motor protector is a specific model number for the KRIWAN INT69 Y Diagnose motor protection relay, designed for monitoring motor temperature and phase conditions.
Key Features and Specifications
- This device protects electric motors of compressors by monitoring temperature via PTC or AMS sensors and also includes phase monitoring functions.
- Model Name: KRIWAN INT69 Y Diagnose
- Part Number: 31A634
- Function: Motor protection against thermal overload, incorrect phase sequence, and phase failure.
- Supply Voltage: AC 50/60Hz 24V
- Sensor Type: Accepts 1-2 AMS sensors in series or 1-9 PTC sensors in series (according to DIN 44081, DIN 44082).
- Temperature Monitoring:
Static: Triggers an immediate switch-off when the nominal response temperature of the sensors is reached. - Dynamic: Shuts off the motor immediately if the temperature rises unusually quickly, even if the static limit is not yet reached.
- Phase Monitoring:
Monitors for incorrect phase sequence (active about 1 second after motor start for 5 seconds).Monitors for phase failure (active from 1 second after motor start until motor stop).
- Diagnostics: Features a diagnose function that stores operating and malfunction data in a non-volatile memory for later analysis.
- Output Relay: Potential-free changeover contact (Rated data: AC 250V max. 6A).
- Reset: The lock or reset delay can be cleared via a main reset (interrupting the supply voltage for >5 seconds).
- Ambient Temperature Range: -30°C to +70°C.
Functional Description
The temperature monitoring in the motor winding is done according to the static evaluation process; the motor is switched off immediately if the nominal response temperature of the built-in AMS or PTC sensors is reached.
A short circuit at an AMS or PTC input also leads to a switch-off. A short cycling leads to a reset delay.
Following cooling off and/or error rectification and subsequent restart delay, the compressor may be restarted. Restarting after a lock-out is only possible after a reset.
The phase monitoring of the motor voltage is active 1 second after the start of the motor.
The correct phase sequence is monitored for 5 seconds, the phase failure is monitored for the total motor running time. If a wrong phase sequence is detected, the motor protector will lock switch-off, if there is a phase failure then a switch-off takes place.
After motor stop, the phase monitoring is deactivated for approximately 15 seconds to prevent unintended locking due to brief reverse running of the compressor.
For operation in the specified manner, the supply voltage has to be on permanently on the INT69 Y Diagnose.

If a wrong phase sequence is detected, the motor protector will lock switch off, if there is a phase failure then a switch-off takes place.
After motor stop, the phase monitoring is deactivated for approximately 15s to prevent unintended locking due to brief reverse running of the compressor.

This motor protector is mainly employed on compressors which are qualified acc. to IEC/EN 60335.
Functional Description
The temperature monitoring of the motor winding is done with two evaluation processes:
1) Static: Switch-off is immediate if the nominal response temperature of the built-in AMS or PTC sensors is reached.
2) Dynamic: If the temperature increases unusually quickly, the motor is switched off immediately even if the temperature is still far below
the nominal response temperature. This prevents excess temperatures from occurring.
A short circuit at an AMS or PTC input also leads to a switch-off.
After expiration of the reset delay and elimination of the error or cooldown, the compressor can be restarted.

Functional Description
• The INT69 E1 can monitor up to nine PTC thermistors even with differing rated shut-off temperatures. If one or more PTC thermistors become highly resistive, the motor protector switches off and locks.
• The monitoring of the phase sequence becomes active 1 second after the motor has started, for a time window of 5 seconds. In case of a wrong phase sequence the relay switches off and locks.
• The phase failure detection is active for about 1 second after the motor starts until the motor stops. In case of a detected phase failure, the motor is shut-off and a restart commences after about 10 seconds.
After the third shut-off, caused by a phase failure, within 12 minutes or at the 10th shut-off within 24 hours, there is a locked shut-off.
• After the motor is shut off, the phase monitoring is inactive for 10 seconds to avoid an unintended shut off by a motor that possibly may be rotating in reverse.
• The lock-out can be removed by a mains reset (>5s).
• The sensor and supply circuits are galvanically isolated from each other.
• The relay output is designed as a potential-free change-over contact in closed-circuit principle.
• The INT69 E1 is not suitable for use with frequency converters.
