4405-178 Motor Protector

4405-178 Motor Protector

The temperature monitoring of the motor winding is done with two evaluation processes:

Static:        Switch-off is immediate if the nominal response temperature of the built-in AMS or PTC sensors is reached.
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.

Supply Voltage …………….AC 50/60Hz 115-240V; -15….+10% 3VA

Motor Voltage ……………..3 AC 50/60Hz 200-690V ±10%

Ambient Temp ……………-22 ~ 158°F (-30 ~ + 70°C)

4405-178 Motor Protector

Application

The compressor protection INT69HBY Diagnosis is a further development of the reliable motor protectors. Additional inputs for the phase monitoring as well as supplementary flexible-response protective functions help to improve the availability

and extend the service life of a refrigeration system.

The INT69HBY Diagnosis automatically saves operational and error data in a non-volatile memory. The data can be retrieved on a PC and analyzed for diagnosis.

The full scope of the diagnosis is achieved by using a specific AMS sensor.

This motor protector is mainly employed on compressors of which the motors direction of rotation is essential for the function.

 

Functional Description

The temperature monitoring of the motor winding is done with two evaluation processes:

  • Static: Switch-off is immediate if the nominal response temperature of the built-in AMS or PTC sensors is reached.
  • 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. A short cycling leads to a reset delay.

After cool down or elimination of the error and a subsequent reset delay, the compressor can be restarted; restarting after locking only after 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

or there is a phase failure, the motor protector will lock switch off.

After motor stop, the phase monitoring is deactivated for approx. 20 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 INT69HBY Diagnosis.

The built-in LED signals the current status of the motor protector (see flash code).

The mounting, maintenance and operation are to be carried out by an electrician.

The valid European and national standards for connecting electrical equipment and cooling installations have to be observed. Connected sensors and connection lines that extend from the terminal box have to feature at least a basic insulation
