from opening. It can be unlocked approximately after 2 minutes of the program end.
This time delay is caused by the PTC which is assambled in the door lock.
8.7.1. Technical Features
Lock Time (20 °C)
2” – 6”
Unlock Time (20 °C)
35” – 75”
Nominal voltage
220 V
Nominal current
16 (4) A
8.7.2. Checking of Component
Check the resistance value on the component with multi-meter as shown in below figures.
Resistance value on the PTC should be 1000
Ω ±50% at 25 °C. That resistance value can be measured from terminal 3-4 (See wiring diagram page 51
below).
