PR 5714 with Pt100 sensor offers these features:
• continuous monitoring of the motor temperature
• protection against too high motor temperature.
Protecting the motor against too high motor temperature is the simplest and cheapest way of avoiding that the motor life is reduced. The Pt100 sensor ensures that the operating conditions are not exceeded and indicates when
it is time for service of the motor.
Monitoring and protection by means of a Pt100 require the following parts:
• Pt100 sensor
• PR 5714 relay
• cable.
The following temperature limits are preset on delivery:
• 60 °C warning limit
• 75 °C stop limit.
To set the warning limit, observe the temperature at normal operation and add 10 °C. Additionally add 10 °C for stop limit.
