Spécifications des produits
Brand ZIEHL
Country of origin Germany
Rated supply voltage AC 220 - 240 V ±10 %, 50/60 Hz, 3VA
Protection housing IP 30
Protection terminals IP 20
Switching point < 4000 Ω
Ambient temperature range -20...+55 °C
Connectable PTC resistors 1...6 PTC according DIN VDE V 0898-1-401 (formerly DIN 44081/82)

The PTC-resistor relay MS 40 ZT monitors particularly engines at elevator cars and lifts. A pulse input monitors the movement of the elevator car as long as the motor is switched on.

  • watchdog timing adjustable 5 - 50 s.
  • temperature monitoring with PTC-resistor
  • integrated RESET-button
  • LED for temperatur alarm
  • LED for watchdog alarm

At elevator systems the temperature of the motor and the travelling motion have to be monitored. With the car at rest and contact between terminals 2 and 5 closed, the integrated relay picks up (terminals 8, 9 connected). The time monitoringstarts with the opening of the contact between terminals 2 and 5. Then the pulse input between terminals 3 and 6 must continously open and closeduring travelling motion. When the pulse stops or the nominal response temperature of the PTC-resistor is exceeded, the relay releases. Each disconnection is locked. A restart by pressing the RESET-button is only possiblewith closed contact between terminals 2 and 5 and low-resistive sensor.
