3. Step-by-Step Commissioning Guide
Unless there´s some special/different things, the setting should be adjusted as below:
- θ1 if set to: 120°C means : contact relay K1 after Time Delay will be open if temp above 120°C
- θ2 if set to: 100°C means : contact relay K2 after Time Delay will be open if temp above 100°C
If temperature below the setting, relays K1 + K2 are energized (contact closed).
For Linear Motor (Liwind or Liweb) set :θ1 to 120°C and :θ2 to 100°C.
For Main Extrusion Motor insulation class H (watercooled ELIN) set :θ1 to 180°C and :θ2 to 160°C.
For Chill Roll Motor 1FW6 set :θ1 to 130°C and :θ2 to 100°C.
Others typically insulation class F (see name plate) set :θ1 to 145°C and :θ2 to 135°C.
- Set Hysteresis to 5.
- Set Time Delay to 1,0 second.
- Set Circuit Prin. to CLOSED.
- Set mode to OVER
- Set sensor type to K84 (KTY84)
