The cablemust be connected to ground in compliance with the standard regardingelectromagnetic compatibility. Inductive loads (e.g. solenoid valves) connected to the melter must beequipped with a protective device (e.g. recovery diode) that disables theinductive voltage generated when an inductive load is switched off. The permitted voltage deviation is 10%. In Field bus mode (option Fieldbus communication) the unit can not becontrolled via the interface.Digital inputsPin Input Function1* 24 VDC Internal (melter)2* 0 VDC External (customer’s)NOTE: Customer connects his reference potential here, if 24 VDC is provided bycustomer.3 0 V24 V Rising edge: Heaters ON (main contactor closes)0 V24 V Falling edge: Heaters OFF (main contactor opens)4 24 V: All motors ON (collective enable)0 V: All motors OFF5 24 V: Enable Motor 10 V: No Motor 1 enable6 24 V: Enable Motor 20 V: No Motor 2 enable7 24 V: Enable Motor 30 V: No Motor 3 enable8 24 V: Enable Motor 40 V: No Motor 4 enable9 0 V24 V Rising edge: Switch on Standby0 V24 V Falling edge: Switch off Standby10 0 V24 V Rising edge: Key-to-line mode (for all motors)0 V24 V Falling edge: Manual mode (for all motors)* selectable
